     DESCRIPTION OF EMBODIMENT 
     Now, an embodiment of the present invention will be described with reference to  FIGS. 1 to 14 . A route evaluation apparatus according to the embodiment of the present invention can be applied to management systems that manage workers in charge of work in assigned areas, in various industries. Hereafter, an example will be described in which the route evaluation apparatus is applied to a management system that manages delivery workers who deliver cargos, flyers, mail pieces such as letters and postcards, or the like. That is, an example will be described in which delivery workers in charge of delivery work at the distribution center of a distribution business, post office, or the like are regarded as workers in charge. 
     To allow the delivery workers to efficiently perform such delivery work, it is common to sort cargos, flyers, mail pieces such as letters or postcards, or the like into predetermined areas (blocks) at the distribution center and to cause the delivery workers to deliver the cargos or the like to the blocks assigned to the delivery workers through predetermined routes. While the delivery workers perform such delivery work through the predetermined scheduled routes, they may actually perform such delivery work through routes different from the scheduled routes on the basis of their know-how. To grasp the actual state of such delivery work and use the actual state to set optimum scheduled routes, the route evaluation apparatus according to the present embodiment is configured to be able to evaluate the travel routes of the delivery workers in terms of the required time period and work efficiency as follows. 
     [Functional Configuration of Management System  100 ] 
     First, the functional configuration of a management system  100  according to the embodiment of the present invention will be described.  FIG. 1  is a diagram showing an example of the system configuration of the management system  100 . As shown in  FIG. 1 , the management system  100  includes multiple (two in  FIG. 1 ) delivery worker terminals  1 A and  1 B, a management server  2 , and a manager terminal  3  that are connected through a network  4 , including a public wireless communication network typified by the Internet network, mobile phone network, or the like. In the management system  100  thus configured, the management server  2  and manager terminal  3  form a route evaluation apparatus  5  according to the embodiment of the present invention. The management server  2  or manager terminal  3  alone may form the route evaluation apparatus  5 . The network  4  also includes a closed communication network provided in a predetermined control area, such as a wireless LAN and Wi-Fi® (Wireless Fidelity). 
     The delivery worker terminals  1 A and  1 B are held in clothes pockets, bags, pouches, or the like of the delivery workers A and B, or disposed in the cradles or the like of vehicles  6 A and  6 B used for delivery work. In the present embodiment, smartphones or tablet terminals, mobile phones, personal digital assistants (PDAs), and various types of wearable terminals that are connectable to a public wireless communication network are collectively referred to as the delivery worker terminals  1 A and  1 B. The delivery worker terminals  1 A and  1 B have the same configuration. The number of delivery worker terminals may be three or more. The vehicles  6 A and  6 B are transportation vehicles, such as four-wheeled vehicles, motorcycles, bicycles, or carts.  FIG. 1  shows a light truck (e.g., a truck having a predetermined displacement or less)  6 A, which is widely being used to deliver cargoes, flyers, mail pieces such as letters and postcards, or the like, and a motorized bicycle (e.g., a motorcycle including a motor having a predetermined displacement or less)  6 B as an example. The delivery workers A and B may perform delivery work on foot without using the vehicle  6 A or  6 B. 
     Next, the configuration of the delivery worker terminals  1 A and  1 B, management server  2 , and manager terminal  3  will be described. 
     &lt;Delivery Worker Terminals  1 A and  1 B&gt; 
     First, the delivery worker terminals  1 A and  1 B will be described. Various types of application software can be installed on the delivery worker terminals  1 A and  1 B. The delivery worker terminals  1 A and  1 B form a part of the management system in accordance with application software installed on smartphones. By using commercially available smartphones, the system construction cost can be suppressed. 
       FIG. 2  is a block diagram showing a schematic configuration of the delivery worker terminals  1 A and  1 B. As shown in  FIG. 2 , the delivery worker terminal  1 A includes a control unit  10 , a storage unit  11 , a wireless unit  12 , a sensor unit  13 , a display unit  14 , and an input unit  15 . 
     The storage unit  11  consists of a semiconductor memory, hard disk, or the like. The storage unit  11  stores software, including an operating system (OS) and application programs for supporting delivery work, and various types of information, including map information such as road maps and residential maps and customer information about delivery destinations. The customer information includes the addresses and phone numbers of the delivery destinations, as well as customer-related information, such as whether the customers have delivery boxes. The software, map information, and customer information may be previously stored in the storage unit  11 , or acquired from the management server  2 . 
     The wireless unit  12  includes a digital signal processor (DSP) and the like and is configured to be able to wirelessly communicate with the management server  2  through a wireless communication network typified by a mobile phone network, such as 3G, LTE, 4G, or 5G. The wireless unit  12  may include a near-field wireless communication unit (not shown) capable of using a near-field wireless communication technology, such as Wi-Fi® or Bluetooth®. The wireless unit  12  is able to transmit a login ID for identifying the delivery worker A or B (“delivery worker ID”), information on the current location of the delivery worker A or B or vehicle  6 A or  6 B, speed information, and the like to the management server  2 . 
     The sensor unit  13  includes a GPS sensor  13   a  that receives locating signals from multiple GPS satellites and measures the absolute location (latitude, longitude) of the delivery worker A or B corresponding to the delivery worker terminal  1 A or  1 B, a gyro sensor  13   b  that detects the angular velocity, and the like. If it is difficult to receive locating signals from the GPS satellites, the current location of the delivery worker A or B or vehicle  6 A or  6 B may be calculated using Assisted Global Positioning System (AGPS) communication on the basis of information on the base stations of the wireless communication network acquired from the wireless unit  12 . 
     The display unit  14  consists of a display device, such as a liquid crystal display or organic EL panel. The display unit  14  receives an instruction from the control unit  10  and displays a map, a button icon for operating a touchscreen, or the like. The display unit  14  is also able to display various types of information, such as the current location of the delivery worker A or B or vehicle  6 A or  6 B, a map around the current location, and a map around the delivery destination. 
     The input unit  15  consists of a physical switch, such as a numeric keypad, operated by the delivery worker A or B, an input device (not shown), such as a touchscreen, disposed so as to be overlaid on the display surface of the display unit  14 , or the like. The input unit  15  outputs a signal based on operation input, such as depression of the numeric keypad or touchscreen by the delivery worker A or B, to the control unit  10 . Thus, for example, the screen display of the display unit  14  is changed. 
     Although not shown, the delivery worker terminals  1 A and  1 B may further include a speaker, vibrator, light, microphone, or the like. The speaker, vibrator, or light notifies the delivery worker of various types of information through a sound, vibration, or light. The speaker outputs a sound to the delivery worker, and the microphone collects a sound or the like issued from the delivery worker. Thus, the delivery worker terminals  1 A and  1 B are able to output various types of information from the speaker in the form of sounds and to input various types of commands inputted in the form of sounds through the microphone by the delivery worker to the control unit  10  using a sound recognition technology. 
     The control unit  10  includes a microprocessor including a CPU, RAM, ROM, I/O, and the like. The CPU executes a previously stored program and transmits and receives signals to and from the storage unit  11 , wireless unit  12 , sensor unit  13 , display unit  14 , and input unit  15 . The control unit  10  includes, as functional elements, a display control unit  101 , a connection processing unit  102 , and a location information notification unit  103 . 
     The display control unit  101  controls the screen display of the display unit  14  by generating image signals in response to an operation on the input unit  15  or in response to the wireless unit  12  receiving various types of information and transmitting the image signals to the display unit  14 . Screens that the display control unit  101  causes the display unit  14  to display include a login screen for logging in to the management system  100 , and the like. 
     The connection processing unit  102  transmits, to the management server  2  through the wireless unit  12 , a login ID and a password inputted by the delivery worker A or B on the login screen displayed on the display unit  14  through the input unit  15 . Thus, the delivery worker terminal  1 A or  1 B is communicatively connected to the management server  2 . The delivery worker performs this login input when starting to work, that is, when departing from the distribution center. Also, when logout is inputted through the input unit  15 , the connection processing unit  102  transmits the logout to the management server  2  through the wireless unit  12 . Thus, the communication connection between the delivery worker terminal  1 A or  1 B and management server  2  is complete. The delivery worker performs this logout input when finishing work, that is, when returning to the distribution center. Logout may be automatically performed on the basis of the time or location information when the delivery worker returns to the distribution center. 
     The location information notification unit  103  transmits information on the current location of the delivery worker A or B or vehicle  6 A or  6 B traveling with the delivery worker terminal  1 A or  1 B calculated on the basis of GPS signals received by the sensor unit  13  (GPS sensor  13   a ), current time information acquired from a clocking unit (not shown), and the like to the management server  2  through the wireless unit  12  at predetermined time intervals (e.g., at intervals of 1 s) such that these pieces of information are associated with the delivery worker ID. The current time information includes not only the time but also the year, month, day, and the like. 
     The positions of the delivery workers A and B or vehicles  6 A and  6 B change from moment to moment. For this reason, when current location information is acquired at predetermined time intervals, the location obtained from the latest current location information and the actual location may not exactly match each other. However, the deviation is small and therefore the location obtained from current location information acquired at predetermined time intervals can be considered as the current location. Multiple pieces of information, such as information on the current location of the delivery worker A or B or vehicle  6 A or  6 B acquired at predetermined time intervals and current time information, may be collectively transmitted at once (so-called “burst transmission”). The time intervals at which information on the current location of the delivery worker or vehicle, and the like are acquired (e.g., intervals of 1 s), the number of pieces of information transmitted at once when burst-transmitting multiple pieces of information collectively, or the like may be previously set. 
     &lt;Management Server  2 &gt; 
     Next, the management server  2  will be described. While, in the present embodiment, the management server  2  will be described as a single server having various functions, it may be a distributed server consisting of servers having different functions or may be realized by a cloud server (virtual server). 
       FIG. 3  is a block diagram showing a schematic configuration of the management server  2 . As shown in  FIG. 3 , the management server  2  includes a control unit  20 , a storage unit  21 , a communication unit  22 , a display unit  24 , and an input unit  25 . The display unit  24  and input unit  25  may be omitted or may consist of other information terminals (not shown) connected to the management server  2 . 
     The storage unit  21  consists of a semiconductor memory, hard disk drive, or the like. The storage unit  21  stores software, such as an operating system (OS) and applications, and other various types of information. For this reason, various storage areas, such as a delivery worker information area  211 , a vehicle information area  212 , a delivery destination information area  213 , a map information area  214 , and a management information area  215 , are ensured in the storage unit  21 . An information area is, for example, a table in a database management system, or the like. 
     The delivery worker information area  211  is an information area in which delivery worker information used to manage each delivery worker, such as the name of the delivery worker and the ID of the center to which the delivery worker belongs, is stored so as to be associated with the employee ID of the delivery worker (also referred to as the delivery worker ID), which is identification information of the delivery worker. A vehicle ID, which is identification information of a vehicle used by each delivery worker, that is, the vehicle  6 A or  6 B, is also stored in the delivery worker information area  211  so as to be associated with the delivery worker ID. For example, the manager of the distribution center sets the association of the vehicle IDs with the delivery worker IDs before daily delivery work is started. 
     The vehicle information area  212  is an information area in which information on each vehicle, including the vehicle type, such as four-wheeled vehicle, motorcycle, or bicycle, and the size of the cargo room, is stored so as to be associated with the vehicle ID. 
     The delivery destination information area  213  is an information area storing delivery destination information, such as the addresses (latitudes, longitudes) and phone numbers of the delivery destinations, blocks including the delivery destinations, and the delivery workers A and B in charge of the blocks including the delivery destinations. The blocks are areas previously set by the manager of the distribution center to sort delivery work. For example, each block corresponds to one or more city blocks and consists of delivery destinations consisting of 10 to 30 households. The delivery workers A and B are in charge of assigned areas each consisting of multiple blocks. 
     The map information area  214  is an information area in which map information is previously stored. The map information includes road link information, map data for displaying the background, such as roads and road maps, and the like. Such map information is updated periodically. 
     The management information area  215  is an information area storing information on the scheduled routes of the delivery workers A and B previously set by the manager of the distribution center, the amount of work in each block, the time-series locations of the delivery workers A and B or vehicles  6 A and  6 B acquired from the delivery worker terminals  1 A and  1 B, and sections set by the manager of the distribution center. The amount of work in each block refers to the amount of cargos, flyers, mail pieces such as letters and postcards, or the like delivered. As the amount of work in each block, the number of delivery households in each block is previously set on the basis of the map information, customer information, and the like, or the number of actually delivered cargos, flyers, mail pieces such as letters and postcards, or the like is set through the manager terminal  3  or the like. 
       FIG. 4  is a diagram showing a scheduled route RTS and an actual route RTA. As shown in  FIG. 4 , for example, the order in which a delivery worker, for example, the delivery worker A, passes through assigned blocks BL 1  and BL 2  (BL 1 →BL 2  and the like in  FIG. 4 ) and the order in which the delivery worker A passes through delivery destinations in the blocks BL 1  and BL 2  ( 1 → 2  and the like in  FIG. 4 ) are previously set as the scheduled route RTS of the delivery worker A. Information on the scheduled route RTS is transmitted to the manager terminal  3  of the distribution center and displayed on a map. The manager is able to use this information to arrange cargos, flyers, mail pieces such as letters and postcards, or the like to be delivered by the delivery worker A, in the order of delivery at the distribution center. The information on the scheduled route RTS may be transmitted to a sorter or the like of the distribution center so that cargos, flyers, mail pieces such as letters and postcards, or the like are automatically arranged in the order of delivery. 
     Information on the time-series locations of the delivery workers A and B or vehicles  6 A and  6 B acquired from the delivery worker terminals  1 A and  1 B is also transmitted to the manager terminal  3  and displayed on a map. For example, the location of the delivery worker A is displayed as a plotted point at predetermined time intervals. A line obtained by connecting the plotted points corresponding to the locations of the delivery worker A on a time-series basis is displayed as the actual route RTA of the delivery worker A. For example, the adjacent plotted points are connected by straight lines on a time-series basis. 
       FIG. 5  is a diagram showing setting of sections. The manager of the distribution center sets sections SCT 1  and SCT 2  corresponding to the blocks BL 1  and BL 2  on the actual route RTA displayed on the manager terminal  3  along the scheduled route RTS, that is, in the previously set order of passage. For example, when setting the section SCT 1  corresponding to the block BL 1 , the manager places a cut icon CT 1  specifying the start point of the section SCT 1  and a cut icon CT 2  specifying the end point thereof, as shown in  FIG. 5 . 
     The cut icons CT (CT 1 , CT 2 ) are placed as line-segment icons or rectangular icons, and the display positions, display directions, and sizes (lengths) thereof on a map are determined in accordance with operations performed on the icons by the manager. The cut icons CT are placed with a length corresponding to the road width so as to intersect the actual route RTA, for example, so as to be perpendicular to the actual route RTA. The cut icons CT may be points, circles around points, or areas (geofences) inside polygons. By placing the cut icons CT 1  and CT 2 , a section from a plotted start point Pin 1  immediately behind the cut icon CT 1  to a plotted end point Pout 1  immediately before the cut icon CT 2 , of the actual route RTA is set as a section SCT 1 . The section SCT 1  is highlighted, for example, by differentiating the color, shape, or size of the plotted points thereof from that of the plots of the other sections. In this way, the manager is able to specify the desired section SCT 1  with an intuitive operation as if the manager cut the section SCT 1  from the actual route RTA displayed on the manager terminal  3  using scissors. 
     Information on the positions of the cut icons CT specifying the start points and end points of the sections SCT 1  and SCT 2  (information on the display positions on the map) is stored in the management information area  215  for each of the sections SCT 1  and SCT 2  as section information. The information on the positions of the cut icons CT specifying the sections SCT 1  and SCT 2  can be read and used. For example, when setting the section SCT 2  corresponding to the block BL 2 , which is a block immediately after the block BL 1  in the order of delivery, the start point of the block BL 2  can be specified by the cut icon CT 2  specifying the end point of the immediately preceding block BL 1 , as shown in  FIG. 5 . The sections SCT 1  and SCT 2  corresponding to the blocks BL 1  and BL 2  may also be set on an actual route RTA on a different day of the week or in a different time slot on the basis of information on the positions of the cut icons CT specifying the sections SCT 1  and SCT 2  stored in the management information area  215 . 
       FIGS. 6A and 6B  are diagrams showing selection of the start points and end points of the sections SCT 2  and SCT 3  following the section SCT 1  with the start point of the section SCT 1  specified by the cut icon CT 1  and show the time-series locations of the delivery worker A or B as plotted points P 1  to P 13 . The cut icon CT 2  of  FIGS. 6A and 6B  specifies the plotted end point Pout 1  of the section SCT 1 , as well as specifies the plotted start point Pin 2  of the section SCT 2  following the section SCT 1 . A cut icon CT 3  of  FIG. 6B  specifies the plotted end point Pout 2  of the section SCT 2 , as well as specifies the plotted start point Pin 3  of a section SCT 3  following the section SCT 2 . As shown in  FIGS. 6A and 6B , when the delivery worker A or B makes a round trip on the same place, for example, on the same road, the actual route RTA may pass through the cut icons CT multiple times. 
     In an example in  FIG. 6A , the plotted end point Pout 1  of the section SCT 1  and the plotted start point Pin 2  of the section SCT 2  following the section SCT 1  are specified by the cut icon CT 2 . As shown in  FIG. 6A , the actual route RTA including the plotted points P 1  to P 13  first passes through the cut icon CT 2  between the plotted points P 3  and P 4  and then again passes through the cut icon CT 2  between the plotted points P 10  and P 11 . 
     In this case, the actual route RTA is divided into the sections SCT 1  and SCT 2  between the plotted points P 3  and P 4 , between which the actual route RTA first passes through the cut icon CT 2  on a time-series basis. That is, the plotted point P 3  is specified as the plotted end point Pout 1  immediately before the cut icon CT 2  (as the end point of the section SCT 1 ), and the plotted point P 4  is specified as the plotted start point Pin 2  immediately behind the cut icon CT 2  (as the start point of the section SCT 2  following the section SCT 1 ). Thus, a section up to the plotted point P 3  of the actual route RTA is set as the section SCT 1  and highlighted. The confirmed section SCT 1  is regarded as having been cut from the actual route RTA and is not considered when setting the sections SCT 2  and SCT 3  subsequently. 
     In an example in  FIG. 6B , the plotted end point Pout 2  of the section SCT 2  following the set section SCT 1  and the plotted start point Pin 3  of the section SCT 3  following the section SCT 2  are specified by the cut icon CT 3 . As shown in  FIG. 6B , the actual route RTA including the plotted points P 4  to P 13 , from which the set section SCT 1  has been cut, passes through the cut icon CT 3  between the plotted points P 10  and P 11 . Thus, the actual route RTA is divided into the sections SCT 2  and SCT 3  between the plotted points P 10  and P 11 , and the plotted point P 10  immediately before the cut icon CT 3  is specified as the plotted end point Pout 2  of the section SCT 2 , and the plotted point P 11  immediately behind the cut icon CT 3  is specified as the plotted start point Pin 3  of the section SCT 3 . 
     In this way, the manager is able to divide the actual route RTA obtained by connecting the time-series plotted multiple points displayed on the manager terminal  3 , into desired sections with an intuitive operation as if the manager cut the sections from the actual route RTA sequentially from one end to another using scissors. Even if the actual route RTA makes a round trip on the same place, the manager is able to divide the actual route RTA into multiple sections in the order of passage on a time-series basis. Note that, for example, a technique of dividing the actual route RTA using mesh areas AR 1  to AR 25  corresponding to the latitude and longitude, as shown in  FIG. 13 , is also conceivable. However, such a technique has difficulty in dividing the actual route RTA into multiple sections in the order of passage on a time-series basis. 
     The communication unit  22  implements a communication protocol enabling wireless communication, such as 3G, LTE, 4G, or 5G, to communicate with the delivery worker terminals  1 A and  1 B. On the other hand, the communication unit  22  implements a communication protocol enabling wired communication (e.g., Internet line or the like) or wireless communication to communicate with the manager terminal  3 . 
     The control unit  20  includes a processor including a CPU, RAM, ROM, I/O, and the like. The control unit  20  includes, as functional elements, a connection processing unit  201 , an information acquisition unit  202 , a start point/end point selection unit  203 , a required time calculation unit  204 , a work efficiency calculation unit  205 , a matching determination unit  206 , and an information output unit  207 . 
     The connection processing unit  201  processes login from the delivery worker terminal  1 A or  1 B and connects the delivery worker terminal  1 A or  1 B to the management server  2 . The connection processing unit  201  also processes logout from the delivery worker terminal  1 A or  1 B and completes the connection between the delivery worker terminal  1 A or  1 B and the management server  2 . The connection processing unit  201  also processes login from the manager terminal  3  and connects the manager terminal  3  to the management server  2 , as well as processes logout from the manager terminal  3  and completes the connection between the manager terminal  3  and management server  2 . 
     The information acquisition unit  202  acquires various types of information by receiving data transmitted from the delivery worker terminals  1 A and  1 B to the management server  2  and data transmitted from the manager terminal  3  to the management server  2 , through the communication unit  22 . The information acquired by the information acquisition unit  202  includes information on the locations of the vehicles  6 A and  6 B transmitted from the location information notification units  103  of the delivery worker terminals  1 A and  1 B and time information corresponding to the location information, information on the scheduled routes and sections of the delivery workers A and B transmitted from the manager terminal  3 , and the like. Specifically, the location information is represented by the latitude and longitude. 
     The start point/end point selection unit  203  selects the start points and end points of the sections SCT 1  and SCT 2  corresponding to the blocks BL 1  and BL 2  on the basis of section information stored in the management information area  215 , that is, information on the locations of the cut icons CT specifying the start points and end points of the sections SCT 1  and SCT 2 . Specifically, the start point/end point selection unit  203  selects a plotted point immediately behind each cut icon CT as the plotted start point Pin of the following section from among the time-series plotted multiple points forming the actual route RTA, as well as selects a plotted point immediately before the cut icon CT as the plotted end point Pout of the preceding section from thereamong. 
     The required time calculation unit  204  calculates the required time periods in the blocks BL 1  and BL 2  on the basis of information on the time-series locations of the delivery workers A and B or vehicles  6 A and  6 B stored in the management information area  215 . That is, the required time calculation unit  204  calculates the required time periods in the blocks BL 1  and BL 2  on the basis of information on the times of the plotted start points Pin and information on the times of the plotted end points Pout selected by the start point/end point selection unit  203 . For example, when calculating the required time period in the block BL 1 , the required time calculation unit  204  calculates the required time period in the section SCT 1  corresponding to the block BL 1  on the basis of information on the times of the plotted start point Pin 1  and plotted end point Pout 1  of the section SCT 1 , as shown in  FIG. 5 . Information on the required time periods in the blocks BL 1  and BL 2  is transmitted to the manager terminal  3  of the distribution center as route evaluation information. The manager of the distribution center is able to evaluate the actual route RTA by checking the required time periods in the blocks BL 1  and BL 2  through the manager terminal  3 . Thus, for example, the manager is able to divide a block having a long required time period into multiple blocks and assign the blocks to multiple delivery workers. The manager is also able to review the delivery workers in charge of the respective blocks or review the scheduled routes on a day-of-the-week or time-slot basis by making a comparison between the required time periods on the actual routes RTA that differ in delivery worker, day of the week, time slot, or the like. 
     The work efficiency calculation unit  205  calculates the work efficiency in each of the blocks BL 1  and BL 2  on the basis of information on the required time periods in the blocks BL 1  and BL 2  calculated by the required time calculation unit  204  and information on the amounts of work in the blocks BL 1  and BL 2  stored in the management information area  215 . For example, if the required time period in the block BL 1  is 4 min and the number of delivery destination households of 24 in the block BL 1  is registered as the amount of work, the work efficiency is calculated as 6 households/min. If the number of flyers or mail pieces of 24 actually delivered in the block BL 1  is registered as the amount of work, the work efficiency is calculated as 6 pieces/min. Information on the work efficiency in each of the blocks BL 1  and BL 2  is also transmitted to the manager terminal  3  as route evaluation information. The manager of the distribution center is able to evaluate the actual route RTA by checking the work efficiency in each of the blocks BL 1  and BL 2 . 
     The matching determination unit  206  determines whether the scheduled route RTS and actual route RTA match each other, on the basis of information on the scheduled route RTS of the delivery worker A or B stored in the management information area  215  and information on the time-series locations of the delivery worker A or B or vehicle  6 A or  6 B. Specifically, the matching determination unit  206  determines whether the actual route RTA passes through the cut icons CT specifying the start points and end points of the sections corresponding to the respective blocks in the scheduled order. Information on the determination as to whether the scheduled route RTS and actual route RTA match each other is also transmitted to the manager terminal  3  of the distribution center as route evaluation information. The manager of the distribution center is able to evaluate the scheduled route RTS by checking whether the scheduled route RTS and actual route RTA match each other. That is, if it is determined that the scheduled route RTS and actual route RTA do not match each other and the delivery worker is actually selecting a delivery route different from the scheduled route RTS, there may be a rational reason. If so, the manager is able to review the scheduled route RTS. 
     The information output unit  207  outputs various types of information by transmitting data from the management server  2  to the manager terminal  3  through the communication unit  22 . The information outputted by the information output unit  207  includes the required time periods and work efficiency in the blocks BL 1  and BL 2 , the determination as to whether the scheduled route RTS and actual route RTA match each other, and the like. 
       FIG. 7  is a flowchart showing an example of a process performed by the CPU of the management server  2  in accordance with a previously stored program. The process shown by this flowchart is started, for example, when the management server  2  receives a route evaluation information output request from the manager terminal  3 . 
     First, in step S 1 , the information acquisition unit  202  reads the route evaluation information output request received from the manager terminal  3  through the communication unit  22  and reads information on the time-series locations of the specified delivery worker A or B in a specified delivery period. Then, in step S 2 , the information acquisition unit  202  determines whether information on the sections corresponding to the blocks assigned to the specified delivery worker A or B is stored in the management information area  215 . Step S 2  is repeated until the determination becomes YES. 
     If the determination in step S 2  is YES, the process proceeds to step S 3 . The start point/end point selection unit  203  selects the plotted start points Pin and plotted end points Pout of the sections SCT 1  and SCT 2  corresponding to the blocks BL 1  and BL 2 . Then, in step S 4 , the required time calculation unit  204  calculates the required time periods in the blocks BL 1  and BL 2 . Then, in step S 5 , the work efficiency calculation unit  205  calculates the work efficiency in each of the blocks BL 1  and BL 2  on the basis of the required time periods calculated in step S 4  and information on the amounts of work stored in the management information area  215 . Then, in step S 6 , the matching determination unit  206  determines whether the scheduled route RTS and actual route RTA match each other, on the basis of the information on the scheduled route RTS and time-series locations stored in the management information area  215 . Then, in step S 7 , the information output unit  207  transmits, to the manager terminal  3 , route evaluation information including the required time periods and work efficiency in the blocks BL 1  and BL 2  and the determination as to whether the scheduled route RTS and actual route RTA match each other calculated in steps S 4  to S 6 . 
     The manager of the distribution center is able to check the required time periods and work efficiency in the blocks BL 1  and BL 2  and whether the scheduled route RTS and actual route RTA match each other, through the manager terminal  3 . Thus, the management is able to evaluate the travel routes of the delivery worker A or B, that is, the actual route RTA and scheduled route RTS thereof and to review the ranges of the blocks, the delivery worker in charge of the blocks, the scheduled route, and the like in accordance with the evaluation. 
     &lt;Manager Terminal  3 &gt; 
     Next, the manager terminal  3  will be described. The manager of the distribution center uses the manager terminal  3  to check and evaluate the travel routes of the delivery workers A and B. The manager terminal  3  is any type of computer, such as a personal computer, tablet terminal, or smartphone, disposed in the distribution center and transmits and receives information to and from the management server  2  through the network  4 . 
       FIG. 8  is a block diagram showing a schematic configuration of the manager terminal  3 . As shown in  FIG. 8 , the manager terminal  3  includes a control unit  30 , a storage unit  31 , a communication unit  32 , a display unit  34 , and an input unit  35 . 
     The storage unit  31  consists of a semiconductor memory, hard disk drive, or the like. The storage unit  31  stores software, such as an operating system (OS) and applications, and other various types of information. 
     The communication unit  32  implements a communication protocol enabling wired communication (e.g., the Internet line or the like) or a communication protocol enabling wireless communication, such as 3G, LTE, 4G, or 5G, and is connected to the management server  2  to transmit and receive various types of data to and from the management server  2 . 
     The display unit  34  consists of a display device, such as a liquid crystal display or organic EL panel. Upon receipt of an instruction from the control unit  30 , the display unit  34  displays a map, a button icon for operating a touchscreen, or the like. The display unit  34  also displays route evaluation information or the like transmitted from the information output unit  207  of the management server  2 . 
     The input unit  35  consists of physical switches, such as a numeric keypad, operated by the manager, an input device (not shown), such as a touchscreen, disposed so as to be overlaid on the display surface of the display unit  34 , or the like. The manager inputs, through the input unit  35 , a command to change the display screen of the display unit  34 . The manager is able to set, through the input unit  35 , the scheduled routes RTS of the delivery workers A and B, the amounts of work in the blocks BL 1  and BL 2 , and the positions of the cut icons CT specifying the start points and end points of the sections SCT 1  and SCT 2 . 
       FIG. 9  is a diagram showing placement of a cut icon CT on the display screen DP of the display unit  34  through the input unit  35 . In an example in  FIG. 9 , an actual route RTA obtained by connecting time-series plotted multiple points is displayed on the display screen DP of the display unit  34  so as to be overlaid on a map, for example, on a road RD. When the manager specifies a point PS and a point PE on the map displayed on the display screen DP of the display unit  34  by operating the input unit  35  (e.g., a touchscreen), a line segment-shaped cut icon CT having the point PS as one end and the point PE as another end is drawn, that is, placed. Information on the location of the cut icon CT (the display location, display direction, and size on the map) is transmitted to the management server  2  and stored in the management information area  215 . A rectangle having the points PS and PE as a pair of opposite angles may be placed as a cut icon CT, or an ellipse inscribed in a rectangle having the points PS and PE as a pair of opposite angles may be placed as a cut icon CT. The point PS (PE) itself may also be used as a cut icon CT. 
     The control unit  30  includes a processor including a CPU, RAM, ROM, I/O, and the like. The control unit  30  includes, as functional elements, a display control unit  301 , a connection processing unit  302 , an evaluation information request unit  303 , and a server information acquisition unit  304 . 
     The display control unit  301  controls the screen display of the display unit  34  by generating image signals in accordance with an operation on the input unit  35  and transmitting the image signals to the display unit  34 . Screens that the display control unit  301  causes the display unit  34  to display include a login screen for logging in to the management system  100 , a setting screen for setting the scheduled routes RTS of the delivery workers A and B, the amounts of work in the blocks BL 1  and BL 2 , the positions of the cut icons CT specifying the start points and end points of the sections SCT 1  and SCT 2 , a route evaluation screen for displaying route evaluation information, and the like. 
       FIGS. 10A and 10B  show an example of a setting screen DP 1  for setting the positions of cut icons CT specifying the start points and end points of sections. As shown in  FIGS. 10A and 10B , the setting screen DP 1  displays a main menu DP 11 , a map display DP 12 , a playback menu DP 13 , and a task menu DP 14 . 
     The main menu DP 11  shows the name of the distribution center (a distribution center A in  FIGS. 10A and 10B ) on the basis of information on login of the manager. The main menu DP 11  also displays selectable main menus (buttons) BT 1  to BT 3 , such as block registration, time-measured section cut, and cut pattern list. When the button BT 1  is selected by depressing it, a screen is displayed so that the manager can register a new block or change the range of a registered block thereon. When the button BT 2  is selected by depressing it, the setting screen DP 1  of  FIG. 10A  is displayed so that the manager can sequentially place multiple cut icons CT and divide (cut) the actual route RTA into multiple sections on the map display DP 12 . Information on the positions of the sequentially placed multiple cut icons CT is registered as the time-measured section cut pattern of the actual route RTA, for example, so as to be associated with the assigned area. When the button BT 3  is selected by depressing it, a screen having registered cut patterns selectively listed thereon is displayed. 
     The map display DP 12  shows the actual route RTA in a specified delivery period on a map of the area assigned to the delivery worker A specified on the task menu DP 14  along with the scheduled route RTS. The map display DP 12  also shows, on the actual route RTA, a current location icon PA corresponding to the current location of the delivery worker A at a time specified on the playback menu DP 13 . Note that the actual route RTA up to the current location on a time-series basis and the actual route RTA following the current location are displayed by plotted points having different colors. 
     The playback menu DP 13  shows a selectable playback button BT  4  for moving the current location icon PA corresponding to the current location of the delivery worker A at a specific time with a lapse of time and other buttons. The playback menu DP 13  also shows the time corresponding to the current location as a time display TR. When the playback button BT  4  is selected by depressing it, the time on the time display TR proceeds and the current location icon PA moves (is played back) on the actual route RTA with a lapse of time. During playback, a stop button is shown in place of the playback button BT  4 . When the stop button is selected by depressing it, the time on the time display TR stops and the current location icon PA stops on the actual route RTA. 
     The task menu DP 14  shows a block selection menu DP  14   a  for selecting a block, an actual route selection menu DP  14   b  for selecting an actual route RTA, a section setting menu DP  14   c  for setting a section, and a pattern registration menu DP  14   d  for registering a cut pattern. 
     The block selection menu DP  14   a  is used to select a block from blocks which form a scheduled route RTS and whose delivery order is previously set (scheduled delivery order blocks), or a new block (original block). When selecting a block from the scheduled delivery order blocks, a desired area, for example, an area assigned to the delivery worker A, is selected from the previously registered areas through a pulldown menu PD 1  and the ordinal number of the desired block in delivery is specified through a button BT 5  or BT 6 . In an example in  FIG. 10A , the block BL 1  with the first ordinal number in delivery is specified from the six blocks BL 1  to BL 6  included in the area assigned to the delivery worker A. The specified ordinal number in delivery is shown on a delivery ordinal number display NB. When the button BT 6  is depressed, the ordinal number in delivery proceeds to the next block; when the button BT 5  is depressed, it returns to the preceding block. Note that when setting a section on the actual route RTA used for delivery in place of the scheduled route RTS, the button BT 7  is selected by depressing it and a new block is specified. 
     The actual route selection menu DP  14   b  is used to specify a desired delivery period and delivery worker through a pulldown menu PD 2 . When a delivery period and a delivery worker are specified, a corresponding actual route RTA is shown on the map display DP 12 . 
     The section setting menu DP 14   c  is used to specify the start point and end point of a section corresponding to a block specified on the block selection menu DP 14   a.  In the example in  FIG. 10A , the start point and end point of the section SCT 1  corresponding to the block BL 1  that is specified on the block selection menu DP 14   a  and has the first ordinal number in delivery are specified. That is, the cut icon CT 1  specifying the start point of the section SCT 1  and then the cut icon CT 2  specifying the end point of the section SCT 1  are placed on the map display DP 12 . By selecting the buttons BT 8  and BT 9  by depressing them, the cut icons CT 1  and CT 2  can be relocated. When the cut icons CT 1  and CT 2  are placed, the section SCT 1  from the plotted start point Pin 1  to the plotted end point Pout 1  is highlighted and a selectable button BT 10  for confirming the section SCT 1  is displayed. When the button BT 10  is selected by depressing it, the section SCT 1  corresponding to the block BL 1  with the first ordinal number in delivery is confirmed and information on the positions of the cut icons CT 1  and CT 2  are registered. 
     This allows the start point and end point of a section corresponding to the block BL 2  with the second ordinal number in delivery to be specified, as shown in  FIG. 10B . When specifying the start point of a section corresponding to a block with the second or later ordinal number in delivery, the position of the exit of the immediately preceding section is used by selecting a button BT 11  by depressing it. That is, in an example in  FIG. 10B , the start point of the section SCT 2  is specified by the cut icon CT 2  specifying the end point of the section SCT 1 . 
     The pattern registration menu DP 14   d  is used to register all the confirmed sections as one cut pattern. Specifically, by confirming all the desired sections, for example, the sections SCT 1  to SCT 6 , and then selecting a button BT 12  by depressing it, information on the positions of multiple cut icons CT specifying the sections SCT 1  to SCT 6  is registered as one cut pattern. When the button BT 3  of the main menu DP 11  is selected by depressing it, the registered cut patterns are listed. 
       FIG. 11  is an example of a route evaluation screen DP 2  showing route evaluation information. As shown in  FIG. 11 , the route evaluation screen DP 2  displays a main menu DP 21 , a map display DP 22 , a playback menu DP 23 , and a route evaluation display DP 24 . 
     The main menu DP  21  shows the name of the distribution center on the basis of information on login of the manager. The main menu DP  21  also shows selectable main menus (buttons) BT 21  to BT 23 , such as block delivery efficiency list, playback player, and analysis record list. When the button BT 21  is selected by depressing it, a screen having the work efficiency of all the registered blocks listed thereon is displayed. When the button BT 22  is selected by depressing it, a route evaluation screen DP 2  of  FIG. 11  is displayed. When the current location icon PA of the delivery worker A displayed on the map display DP 22  is moved using the playback menu DP 23 , information on the route evaluation of a block corresponding to the current location of the delivery worker A is highlighted on the route evaluation display DP 24 . When the button BT 23  is selected by depressing it, a screen showing an analysis result of route evaluation information is displayed. 
     The map display DP 22  shows a pulldown menu PD 3  for selecting a desired area from the areas whose cut patterns have been registered on the setting screen DP 1  and a pulldown menu PD 4  for specifying a delivery period (the delivery date in  FIG. 11 ) and a delivery worker (the delivery worker A in  FIG. 11 ) whose actual route RTA is desired to be displayed. When a cut pattern and an actual route RTA are specified through the pulldown menus PD 3  and PD 4 , the specified cut pattern and actual route RTA are displayed, as on the map display DP 12  of the setting screen DP 1  ( FIGS. 10A and 10B ). Information on the cut pattern specified through the pulldown menu PD 3  and the delivery period and delivery worker specified through the pulldown menu PD 4  is transmitted from the manager terminal  3  to the management server  2  as a route evaluation information output request. The playback menu DP 23  is similar to the playback menu DP 13  of the setting screen DPI ( FIGS. 10A and 10B ). 
     When the cut pattern, delivery period, and delivery worker are specified through the pulldown menus PD 3  and PD 4  of the map display DP 22  and the route evaluation information output request is transmitted from the manager terminal  3  to the management server  2 , the management server  2  calculates the required time periods and work efficiency in the blocks BL 1  to BL 6 . The required time periods and work efficiency in the blocks BL 1  to BL 6  calculated by the management server  2  are transmitted from the management server  2  to the manager terminal  3  as route evaluation information and displayed on the route evaluation display DP 24 . 
     The route evaluation display DP 24  shows a work time display DP 24   a  showing the work time of the delivery worker A in the specified delivery period and an evaluation result display DP 24   b  showing a route evaluation about each section. 
     By moving up and down a scroll bar SB through the input unit  35  (touchscreen), route evaluations about all the sections, for example, the sections SCT 1  to SCT 6  corresponding to the blocks BL 1  to BL 6 , are displayed. In addition to the route evaluations about the sections SCT 1  to SCT 6 , the evaluation result display DP 24   b  also shows the time period required to travel from the distribution center to the first section SCT 1  and the time period required to travel from the last section (e.g., the sixth section) SCT 6  to the distribution center. The evaluation result display DP 24   b  also shows the time period required to travel from one delivery section to the next delivery section. 
     In an example in  FIG. 11 , the current location icon PA of the delivery worker A displayed on the map display DP 22  is located in the first section SCT 1  and therefore the route evaluation about the first section SCT 1  is highlighted on the route evaluation display DP 24 . The number of pieces delivered and the delivery time period in the block BL 1  corresponding to the section SCT 1 , as well as the delivery efficiency therein is displayed as the route evaluation about the first section SCT 1 . The route evaluation display DP 24  also shows the time slot in which the delivery worker has stayed in the section SCT 1 . The route evaluations about the second to sixth sections SCT 2  to SCT 6  are displayed as well. 
       FIG. 12  shows an example of analysis results of route evaluation information displayed when the button BT 23  is selected on the main menu DP 21  of the route evaluation screen DP 2  and shows the actual performance of the specified delivery worker in the specified delivery period for each travel section. As shown in  FIG. 12 , the actual time and actual efficiency in the specified delivery period, as well as the median value and the difference between the median value and actual value in the data accumulation period (e.g., in each month) are displayed as the analysis results of the route evaluation information. The manager of the distribution center is able to relatively evaluate the delivery time period and delivery efficiency of the specified delivery worker in the specified delivery period by viewing the analysis results of the route evaluation information. Thus, the manager is able to review the delivery workers in charge of the respective blocks or the scheduled routes on the respective days of the week or in the respective time slots. 
     The connection processing unit  302  ( FIG. 8 ) processes login to the management server  2  using, for example, an identification number for identifying the manager or responsible person of the distribution center (center manager ID) and a password. 
     The evaluation information request unit  303  specifies a delivery worker and a delivery period in accordance with an operation on the input unit  35  by the manager and transmits a route evaluation information output request to the management server  2 . 
     The server information acquisition unit  304  acquires route evaluation information or the like transmitted from the management server  2  (information output unit  207 ). Thus, the route evaluation screen DP 2  ( FIG. 11 ) or the analysis results of the route evaluation information ( FIG. 12 ) is displayed on the display unit  34 . 
     [Operation of Management System  100 ] 
     Next, an example of the operation of the management system  100  will be described. For example, when departing from the distribution center, that is, when starting work, the delivery worker A who drives the vehicle  6 A inputs his or her login ID and a password on the login screen displayed on the display unit  14  of the delivery worker terminal  1 A through the input unit  15 . Thus, the management server  2  processes connection from the delivery worker terminal  1 A. Subsequently, the delivery worker terminal  1 A communicates with the management server  2  at predetermined time intervals (e.g., at intervals of 1 s), for example, transmits information on the location of the delivery worker A or vehicle  6 A to the management server  2 . The communication between the delivery worker terminal  1 A and management server  2  continues until the delivery worker terminal  1 A logs out. 
     On the other hand, the manager of the distribution center inputs the center manager ID and a password on the login screen displayed on the display unit  34  of the manager terminal  3  through the input unit  35 . Thus, the management server  2  processes connection from the manager terminal  3 . When the manager specifies the delivery worker A and a delivery period through the input unit  35  (touchscreen), the scheduled route RTS and actual route RTA of the delivery worker A in the specified delivery period are displayed on the display unit  34  ( FIG. 4 ). The manager places the cut icon CT 1  specifying the start point of the section SCT 1  corresponding to the block BL 1  and the cut icon CT 2  specifying the end point thereof on the actual route RTA through the input unit  35  (touchscreen) ( FIG. 5 ). 
     In response to this input, the management server  2  selects the plotted start point Pin and plotted end point Pout of the specified section SCT 1  and calculates the required time period and work efficiency in the section SCT 1  (steps S 1  to S 5 ). Also, when the sections corresponding to all the blocks assigned to the delivery worker A are specified, the management server  2  determines whether the scheduled route RTS and actual route RTA match each other (step S 6 ). Information on the required time period and work efficiency in the section SCT 1  and the determination as to whether the scheduled route RTS and actual route RTA match each other calculated by the management server  2  is transmitted to the manager terminal  3  as route evaluation information. Thus, the route evaluation screen DP 2  ( FIG. 11 ) or analysis results of the route evaluation information ( FIG. 12 ) are displayed on the display unit  34  (step S 7 ). 
     Through the manager terminal  3 , the manager of the distribution center is able to check the required time period and work efficiency in the block BL 1  and whether the scheduled route RTS and actual route RTA match each other and to evaluate the travel routes of the delivery worker A, that is, the actual route RTA and scheduled route RTS thereof. The manager is also able to review the range of the block BL 1 , the scheduled route RTS, or the like in accordance with the evaluation of the travel routes and thus to improve the efficiency of the delivery work of the delivery worker A. The manager is also able to make a comparison between the evaluations of the travel routes of the multiple delivery workers A and B belonging to the distribution center, to review the delivery worker in charge of the blocks BL 1  and BL 2  when necessary, and thus to improve the efficiency of delivery work of the entire distribution center. 
     The present embodiment can achieve advantages and effects such as the following: 
     (1) The route evaluation apparatus  5  is configured to evaluate the travel route of the delivery worker A, B who conducts delivery work. The route evaluation apparatus  5  includes: the information acquisition unit  202  configured to acquire the location information of the delivery worker a, B calculated based on GPS signals received by the GPS sensor  13   a  provided on the delivery worker terminal  1 A,  1 B carried by the delivery worker A, B, and configured to acquire the time information about when the location information is calculated; the display unit  34  configured to display the plurality of plotted points corresponding to the location information based on the location information and the time information acquired by the information acquisition unit  202 ; the input unit  35  (touchscreen) configured to place the cut icons CT 1 , CT 2  on the actual route RTA connecting plotted points next to each other in timing from among the plurality of plotted points displayed by the display unit  34 ; the start point/end point selection unit  203  configured to select the plotted start point Pin corresponding to the cut icon CT 1  placed by the input unit  35  (touchscreen), and configured to select the plotted end point Pout corresponding to the cut icon CT 2  placed by the input unit  35  from among the plurality of plotted points; and the required time calculation unit  204  configured to calculate a required time period for the section SCT 1 , SCT 2  from the plotted start point Pin to the plotted end point Pout selected by the start point/end point selection unit  203  ( FIG. 3 ,  FIG. 8 ). This configuration allows the manager of the distribution center to specify the specific sections SCT 1  and SCT 2  of the travel routes, particularly, the actual route RTA of the delivery worker A or B, to calculate the required time periods, and to evaluate the travel routes. 
     (2) The start point/end point selection unit  203  is configured to select a plotted point nearest in distance to the cut icon CT 1  placed by the input unit  35  (touchscreen) as the plotted start point Pin, and is configured to select a plotted point nearest in distance the cut icon CT 2  placed by the input unit  35  (touchscreen) as the plotted end point Pout. With this, the manager of the distribution center is able to specify the desired sections SCT 1  and SCT 2  with a simple, intuitive operation of simply placing the cut icons CT (CT 1  and CT 2 ) on the actual route RTA displayed on the display unit  34 . 
     (3) The input unit  35  (touchscreen) is configured to place the cut icon CT 1  as a line segment or an area crossing the actual route RTA, and is configured to place the cut icon CT 2  as a line segment or an area crossing the actual route RTA. With this, the manager of the distribution center is able to specify the desired sections SCT 1  and SCT 2  with an intuitive operation as if the manager cut the sections SCT 1  and SCT 2  from the actual route RTA displayed on the manager terminal  34  using scissors. 
     (4) The route evaluation apparatus  5  further includes: the storage unit  21  (management information area  215 ) configured to store the information on the positions of the cut icon CT 1  and the cut icon CT 2  ( FIG. 3 ). With this, the route evaluation apparatus  5  is able to read and use information on the locations of the cut icons CT specifying the sections SCT 1  and SCT 2 . 
     (5) The travel route sequentially passes through a plurality of predetermined blocks BL 1 , BL 2  in a predetermined passing order ( FIG. 4 ,  FIG. 5 ). The input unit  35  (touchscreen) is configured to place a plurality of cut icons CT on each entering points of the plurality of blocks BL 1 , BL 2 , and is configured to place a plurality of cut icons CT on each exiting points of the plurality of blocks BL 1 , BL 2  ( FIG. 5  to  FIG. 6B ). The required time calculation unit  204  is configured to calculate the required time period for each of a plurality of sections SCT 1 , SCT 2  corresponding to the plurality of blocks BL 1 , BL 2  in the delivery order. With this, the manager is able to grasp the required time periods in the blocks BL 1  and BL 2  with respect to the entire actual route that sequentially passes through the multiple blocks BL 1  and BL 2  and to review the scheduled route RTS that sequentially passes through the multiple blocks BL 1  and BL 2 , when necessary. 
     (6) The start point/end point selection unit  203  is configured to select from among the plurality of plotted points a plotted point behind in timing than the plotted end point Pout 1 , Pout 2  of the section SCT 1 , SCT 2  immediately preceding in the predetermined passing order and nearest in timing to the plotted end point Pout 1 , Pout 2  of the section SCT 1 , SCT 2  immediately preceding in the predetermined passing order as the plotted start point Pin 2 , Pin 3  of the section SCT 2 , SCT 3  immediately after in the predetermined passing order ( FIG. 5  to  FIG. 6B ). The time-measured sections are along the order of delivery. For this reason, even if the required time period in a section corresponding to a specific block is measured and then the delivery worker passes through the block a number of times on that day, the measured required time period is not affected. For example, even if the delivery worker travels the sections SCT 1  to SCT 4  corresponding to the blocks BL 1  to BL 4  and then passes through the blocks BL 1  to BL 4  as shown in  FIG. 14 , the measured required time periods in the sections SCT 1  to SCT 4  are not affected. 
     (7) The information acquisition unit  202  is configured to further acquire information about the amount of work predetermined for each of the plurality of blocks BL 1 , BL 2 . The route evaluation apparatus  5  further includes: the work efficiency calculation unit  205  configured to calculate the work efficiency in each of the plurality of blocks BL 1 , BL 2  based on the required time period of each of the plurality of sections SCT 1 , SCT 2  corresponding to the plurality of blocks BL 1 , BL 2  calculated by the required time calculation unit  204  and the information about the amount of work predetermined for each of the plurality of blocks BL 1 , BL 2  acquired by the information acquisition unit  202  ( FIG. 3 ). With this, the manager is able to evaluate the actual route RTA by checking the work efficiency in each of the blocks BL 1  and BL 2 . 
     (8) The information acquisition unit  202  is configured to further acquire information about the scheduled order for passing through the plurality of predetermined blocks BL 1 , BL 2 . The route evaluation apparatus  5  further includes: the matching determination unit configured to determine whether the actual order (actual route RTA) in which the delivery worker A, B actually passes through the plurality of blocks BL 1 , BL 2  and the scheduled order (scheduled route RTS) match each other based on the location information, the time information, and the information about the scheduled order acquired by the information acquisition unit  202  ( FIG. 3 ). With this, the manager is able to evaluate the scheduled route RTS by checking whether the scheduled route RTS and actual route RTA match each other. 
     (9) The information acquisition unit  202  is configured to further acquire information about the scheduled route RTS of the delivery worker A, B. The display unit  34  is configured to further display the scheduled route RTS acquired by the information acquisition unit  202  ( FIG. 10A  to  FIG. 11 ). With this, the manager is able to grasp whether the delivery worker A or B has used the scheduled route RTS and to review the scheduled route RTS when necessary. 
     The above-mentioned embodiment can be modified into various forms. Hereafter, modifications will be described. While, in the above embodiment, an example in which the route evaluation apparatus  5  evaluates the travel routes of the delivery workers has been described, the route evaluation apparatus is not limited to this example as long as it evaluates the travel routes of workers in charge of work. 
     While, in the above embodiment, the GPS sensors  13   a  are mounted on the delivery worker terminals  1 A and  1 B carried by the delivery workers A and B, the GPS sensors may be of any type as long as they are disposed on mobile terminals carried by the workers in charge or disposed on moving bodies driven by the workers in charge. 
     While, in the above embodiment, the information acquisition unit  202  acquires information on the locations calculated by the delivery worker terminals  1 A and  1 B, the information acquisition unit that acquires information on the locations of the workers in charge and information on the times at which the locations have been calculated may be configured otherwise. For example, the management server  2  may calculate the locations on the basis of GPS signals received by the delivery worker terminals  1 A and  1 B. 
     While, in the above embodiment, the cut icons CT are placed through the input unit  35  (touchscreen) of the manager terminal  3 , the icon placement unit that places first and second icons on the travel route may be configured otherwise. For example, the display positions of the cut ions may be moved in conjunction with an operation on a mouse, numeric pad, or the like by the manager. Coordinate values or the like corresponding to the display positions of the cut icons may be directly inputted. 
     While, in the above embodiment, information on the display positions on a map of the cut icons CT is stored in the management information area  215  of the storage unit  21 , the storage unit that stores information on a first line segment or first area and a second line segment or second area may be configured otherwise. For example, the storage unit may store information on the latitude and longitude on a map at which the cut icons are displayed. 
     The above description is only an example, and the present invention is not limited to the above embodiment and modifications, unless impairing features of the present invention. The above embodiment can be combined as desired with one or more of the above modifications. The modifications can also be combined with one another.
