     The utilization supporting system  1  provides a service of proposing matching to a user and a rideshare vehicle registered to utilize the utilization supporting system  1 . Information of the user is recorded in a user DB (database)  32 , and information of the rideshare vehicle is recorded in a rideshare vehicle DB  33 . In addition, reservation information of the rideshare vehicle is recorded in a reservation DB  34 . The rideshare vehicle may be not only a shared vehicle by so-called ridesharing but also a shared vehicle by carsharing or a taxi or the like. 
     In an example in  FIG. 1 , a situation where employees of a Y plant  300  (shortened and described as a plant  300 , hereinafter) of an X company go home to their own houses by utilizing the rideshare vehicles  50 ,  60 ,  70 ,  80  and  90  is shown. Signs  100 ,  101 ,  110 ,  111 ,  120 ,  121 ,  130 ,  131 ,  140 ,  141  and  142  in  FIG. 1  respectively denote the houses of users A 1 , A 2 , B 1 , B 2 , C 1 , C 2 , D 1 , D 2 , E 1 , E 2  and E 3  of the utilization supporting system  1 , who are the employees of the plant  300 . 
     For the rideshare vehicle  50 , a ridesharing plan of traveling a route Ra from a location spot Ps of the plant  300  via a location spot Pa 1  of the house  100  of the user A 1  to a location spot Pa 2  of the house  101  of the user A 2  by a schedule of 17:30-18:00 is determined. For the rideshare vehicle  60 , a ridesharing plan of traveling a route Rb from the location spot Ps of the plant  300  via a location spot Pb 1  of the house  110  of the user B 1  to a location spot Pb 2  of the house  111  of the user B 2  by the schedule of 17:15-17:50 is determined. 
     For the rideshare vehicle  70 , a ridesharing plan of traveling a route Rc from the location spot Ps of the plant  300  via a location spot Pc 1  of the house  120  of the user C 1  to a location spot Pc 2  of the house  121  of the user C 2  by the schedule of 17:00-18:00 is determined. For the rideshare vehicle  80 , a ridesharing plan of traveling a route Rd from the location spot Ps of the plant  300  via a location spot Pd 1  of the house  130  of the user D 1  to the house  131  of the user D 2  by the schedule of 17:30-18:30 is determined. For the rideshare vehicle  90 , a ridesharing plan of traveling a route Re from the location spot Ps of the plant  300  via a location spot Pe 1  of the house  140  of the user E 1  and a location spot Pe 2  of the house  141  of the user E 2  to a location spot Pe 3  of the house  142  of the user E 3  by the schedule of 17:15-17:45 is determined. 
     The user U illustrated in  FIG. 1  is an employee of the plant  300 , and is already registered to utilize the utilization supporting system  1 . The user U has a user terminal  45 , and is about to reserve a rideshare vehicle for going home to a house  150 . By executing a ridesharing matching application provided from the utilization supporting system  1  in the user terminal  45 , the user U communicates with the utilization supporting system  1 , and enjoys a rideshare vehicle utilization supporting service by the utilization supporting system  1 . 
     The utilization supporting system  1  refers to the reservation DB  34 , and extracts a predetermined rideshare vehicle suited to a desired utilization condition of the user U, from the rideshare vehicles, the ridesharing plan of which is already determined. Then, the utilization supporting system  1  transmits, to the user terminal  45 , data of a predetermined ridesharing route guide screen (details will be described later) indicating a scheduled traveling route (predetermined ridesharing route) by the ridesharing plan of the predetermined rideshare vehicle superimposed on a map of the area Ar. 
     The user U can visually recognize the predetermined ridesharing route guide screen displayed at a display unit of the user terminal  45 , select one of the predetermined rideshare vehicles, the ridesharing plan of which is already determined, and apply for a reservation. In the example in  FIG. 1 , the user U can confirm the predetermined ridesharing routes Ra, Rb, Rc, Rd and Re of the rideshare vehicles  50 ,  60 ,  70 ,  80  and  90  that are the predetermined rideshare vehicles, and select the rideshare vehicle from which getting off at a spot near a desired get-off spot Pg is possible, from the rideshare vehicles  50 ,  60 ,  70 ,  80  and  90 . 
     In this way, by proposing matching with the rideshare vehicles  50 ,  60 ,  70 ,  80  and  90 , the ridesharing plan of which is already determined, to the user U, a matching rate is expected to be improved compared to the case of newly retrieving a rideshare vehicle, creating a ridesharing plan and making an arrangement.

     The rideshare vehicle registration unit  11  registers the rideshare vehicle to the utilization supporting system  1 . The rideshare vehicle is registered by recording the information of the rideshare vehicle in the rideshare vehicle DB  33 . As the information of the rideshare vehicle, the rideshare vehicle registration unit  11  records a rideshare vehicle ID (identification) issued to the rideshare vehicle, a model of the rideshare vehicle, a riding capacity, a utilization cost, a utilizable period and the like in the rideshare vehicle DB  33 . 
     The user registration unit  12  registers the user to the utilization supporting system  1 . The user is registered by recording the information of the user in the user DB  32 . As the information of the user, the user registration unit  12  records a user ID issued to the user, a name of the user, a home address, workplace information (a company name, a location, a belonging department and the like) in the user DB  32 . 
     The rideshare vehicle management unit  13  creates the ridesharing plan based on a reservation status for the rideshare vehicle recorded in the rideshare vehicle DB  33 , and records the plan in the reservation DB  34 . As illustrated in  FIG. 3 , in the reservation DB  34 , information of a rideshare vehicle ID  34   a , a ridesharing plan  34   b , and a reserved ridesharing person  34   c  is recorded for each rideshare vehicle.  FIG. 3  illustrates the reservation status of the rideshare vehicles  50 ,  60 ,  70 ,  80  and  90  according to the situation in  FIG. 1 . For example, for the rideshare vehicle  50 , CID-001 is recorded in the rideshare vehicle ID  34   a , and the ridesharing plan of traveling the ridesharing route Ra (Ps→Pa 1 →Pa 2 ) from 17:30 to 18:00 on Feb. 25, 2019 is recorded in the ridesharing plan  34   b . In addition, the users A 1  and A 2  are recorded in the reserved ridesharing person  34   c.    
     The desired get-on time recognition unit  14  recognizes a desired time for the user U to get on the rideshare vehicle, based on desired get-on time information transmitted from the user terminal  45 . The desired use condition recognition unit  15  recognizes a desired use condition of the user U for the rideshare vehicle, based on desired use condition information transmitted from the user terminal  45 . The desired use condition includes a use condition of a compartment of the rideshare vehicle (such as non-smoking) and a condition of a passenger (such as women only) or the like. 
     The retrieval target time zone setting unit  16  sets a prescribed time zone including the desired get-on time (for example, one hour between the hours before and after the desired get-on time) as a retrieval target time zone. Note that the retrieval target time zone may be specified by an operation of the user terminal  45  by the user U. The desired get-on/get-off spot recognition unit  17  recognizes a desired get-on spot and a desired get-off spot of the user U for the rideshare vehicle, based on desired get-on/get-off information transmitted from the user terminal  45 . 
     The predetermined rideshare vehicle extraction unit  18  sets an area including the desired get-on spot and the desired get-off spot of the user U as a retrieval target area of the rideshare vehicle to be matched with the user U. The rideshare vehicle of a matching candidate travels the ridesharing route set within the retrieval target area. In  FIG. 1 , the area Ar is set as the retrieval target area. 
     The predetermined ridesharing route guide unit  19  transmits, to the user terminal  45 , the data of the predetermined ridesharing route guide screen displaying the route of the rideshare vehicle of the matching candidate extracted by the predetermined rideshare vehicle extraction unit  18  superimposed on the map of the retrieval target area. The user U can confirm the predetermined ridesharing route guide screen displayed at a display unit  45   a  of the user terminal  45 , select a desired rideshare vehicle from the rideshare vehicles, the ridesharing plan of which is already determined, and apply for a reservation. Details of the predetermined ridesharing route guide screen will be described later. 
     3. Matching Processing of Rideshare Vehicle with User 
     According to a flowchart illustrated in  FIG. 4 , in the situation illustrated in  FIG. 1 , matching processing of the rideshare vehicle with the user U executed by the utilization supporting system  1  will be described. In step S 1  in  FIG. 4 , when desired get-on condition information indicating a desired get-on condition is received from the user terminal  45 , the utilization supporting system  1  advances the processing to step S 2 . 
     The desired get-on condition includes the desired get-on time information, the desired get-on/get-off spot information, and the desired use condition information described above. In step S 2 , the desired get-on time recognition unit  14  recognizes the desired time for the user U to get on the rideshare vehicle from the desired get-on time information. In addition, the desired get-on/get-off spot recognition unit  17  recognizes the desired get-on spot to the rideshare vehicle for the user U and the desired get-off spot from the rideshare vehicle for the user U, from the desired get-on/get-off spot information. Further, the desired use condition recognition unit  15  recognizes the rideshare vehicle use condition of the user U from the desired use condition information. 
     Here, as illustrated in  FIG. 1 , it is recognized that the desired get-on spot for the user U is Ps (the location spot of the Y plant  300  of the X company), the desired get-off spot is Pg (the location spot of the house  150  of the user U), the desired get-on time is 17:20, and the use condition of the rideshare vehicle is non-smoking. In following step S 3 , the predetermined rideshare vehicle extraction unit  18  sets the area Ar including the desired get-on spot Ps and the desired get-off spot Pg as the retrieval target area of the rideshare vehicle to be matched with the user U. 
     In following step S 4 , the retrieval target time zone setting unit  16  sets a time zone from the hour 17:00 immediately before the desired get-on time 17:20 for the user U to the hour 18:00 immediately after as the retrieval target time zone. In following step S 5 , the predetermined rideshare vehicle extraction unit  18  extracts the predetermined rideshare vehicle for which the ridesharing plan of starting movement on the ridesharing route within the retrieval target time zone (here, 17:00-18:00) is already determined, a reservation is possible, and non-smoking is set as the use condition. In the example in  FIG. 1 , it is assumed that the rideshare vehicle  50  (the ridesharing plan in 17:30-18:00), the rideshare vehicle  60  (the ridesharing plan in 17:15-17:50), the rideshare vehicle  70  (the ridesharing plan in 17:00-18:00), the rideshare vehicle  80  (the ridesharing plan in 17:30-18:30), and the rideshare vehicle  90  (17:15-17:45) are extracted as the predetermined rideshare vehicles and description is given below. 
     In following step S 6 , the predetermined ridesharing route guide unit  19  transmits, to the user terminal  45 , the data of the predetermined ridesharing route guide screen displaying the predetermined ridesharing route which is a moving route of the predetermined rideshare vehicle superimposed on the map of the area Ar. Here, with reference to  FIG. 5 , the predetermined ridesharing route guide screen will be described. A predetermined ridesharing route guide screen  200  illustrated in  FIG. 5  corresponds to the situation in  FIG. 1 , and displays a predetermined ridesharing route map  201  in which predetermined ridesharing routes Ra, Rb, Rc, Rd and Re of the predetermined rideshare vehicles  50 ,  60 ,  70 ,  80  and  90  are superimposed on the map of the area Ar. On the predetermined ridesharing route map  201 , the travel scheduled time and the get-on/get-off spots of the respective predetermined ridesharing routes are illustrated. 
     In addition, the predetermined ridesharing route guide screen  200  displays a rideshare vehicle desired get-on time input column  203 , a rideshare vehicle desired get-on spot input column  204 , a rideshare vehicle desired get-off spot input column  205 , and a desired use condition input column  206 . The user U inputs the utilization condition of the rideshare vehicle to the input columns  203 - 206 , and thus the utilization condition information is transmitted to the utilization supporting system  1 . In the example in  FIG. 5 , by receiving the information of the desired get-off spot Pg, the predetermined ridesharing route guide unit  19  emphatically displays (displays with x in  FIG. 5 ) the get-off spots Pb 1 , Pc 1  and Pd 1  near the desired get-off spot Pg, and improves visibility by the user U. 
     Further, the predetermined ridesharing route guide screen  200  displays an input column  207  for a rideshare vehicle selection condition. The user U selects the desired ridesharing route, the desired get-on spot and the desired get-off spot from the predetermined ridesharing routes Ra, Rb, Rc, Rd and Re displayed on the predetermined ridesharing route map  201 . The user U selects the predetermined ridesharing route by touching one of the predetermined ridesharing routes displayed on the predetermined ridesharing route map  201 . In addition, the user U selects the desired get-on spot and the desired get-off spot by touching the get-on/get-off spots in the selected predetermined ridesharing route.  FIG. 5  illustrates the case where the user U selects the predetermined ridesharing route Pd of the rideshare vehicle  80  (the vehicle ID is CID-004), selects Ps (the location spot of the Y plant of the X company) as the desired get-on spot, and selects Pd 1  (the location spot of the house of the user D 1 ) as the desired get-off spot. 
     Further, the predetermined ridesharing route guide screen  200  displays a reservation status graph  202  (corresponding to a reservation status display portion of the present invention) displaying a count of established reservations for each time zone. The reservation status graph is illustrated by setting hourly time zones (15:00-16:00, 16:00-17:00, . . . ) on a horizontal axis and setting a count of ridesharing already established in each time zone (corresponding to a reservation establishment degree of the present invention) on a vertical axis. In  FIG. 5 , the retrieval target time zone 17:00-18:00 set by the retrieval target time zone setting unit  16  is illustrated with oblique lines. 
     By confirming the reservation status graph, the user U can change the desired get-on time to a time zone in which a reservation may be made, and in accordance with the change of the desired get-on time, the predetermined rideshare vehicle is extracted again by the predetermined rideshare vehicle extraction unit  18 . Then, the predetermined ridesharing route guide unit  19  transmits, to the user terminal  45 , the data of the predetermined ridesharing route guide screen indicating the predetermined ridesharing route of the predetermined rideshare vehicle extracted again. Thus, the matching rate of rideshare vehicles by the user U is expected to be improved. 
     By the user U touching a reservation applying button  208  displayed on the predetermined ridesharing route guide screen  200 , reservation application information indicating a reservation application condition (the predetermined ridesharing route and the vehicle ID of the predetermined rideshare vehicle, the desired get-on spot and the desired get-off spot) inputted in the input column  207  for the rideshare vehicle selection condition is transmitted from the user terminal  45  to the utilization supporting system  1 . 
     In step S 7 , when the reservation application information is received from the user terminal  45 , the rideshare vehicle management unit  13  advances the processing to step S 8 . In step S 8 , the rideshare vehicle management unit  13  transmits reservation inquiry information inquiring propriety of the reservation to an operator terminal used by an operator (a driver, a manager or the like) of the predetermined rideshare vehicle selected by the reservation application condition recognized from the reservation application information, and performs processing of determining matching with the user U. 
     When information of approving the reservation is received from the operator terminal, the rideshare vehicle management unit  13  changes the ridesharing plan of the rideshare vehicle  80 , and adds getting on at the spot Ps and getting off at the spot Pd 1  of the user U. In addition, when the rideshare vehicle  80  can cope with getting off at the location spot Pg of the house of the user U, the rideshare vehicle management unit  13  changes the ridesharing route of the rideshare vehicle  80  so as to go through the location spot Pg. 
     In following step S 9 , the rideshare vehicle management unit  13  transmits, to the user terminal  45 , application result information notifying the propriety of the reservation. In the case where the reservation cannot be made, the user U can deal by applying for the reservation of the other rideshare vehicle  60  or rideshare vehicle  70 , changing the desired get-on time to change the rideshare vehicle to be a selection target or the like. 
     4. Other Embodiments
