Abstract:
A system is disclosed in which maps and travel directions are generated, on the basis of subjective criteria input by a user in a particular business with certain transportation/logistics patterns in a mapping and travel direction inquiry, using data comprising objective geographic road data and subjective links to selectable criteria. The disclosed method of generating driving direction information, comprises creating a database comprising roads and subjective assessment information, of at least one type, associated with at least some of the roads. A driving direction information request associated with at least one of the subjective assessment information types is received from a requester. Driving direction information based, at least in part, on the subjective assessment information is generated and transmitted to the requester. 
     The subjective assessment information includes the identification of the class of the requester. The generation of driving direction information is based more heavily on data collected from individuals of the specified class of requesters.

Description:
TECHNICAL FIELD 
       [0001]    The present invention relates to the generation of maps and directions in response to a consumer inquiry, especially inquiries specifying a starting point and an ending point. 
       BACKGROUND OF THE INVENTION 
       [0002]    One of the services which has come out of the information age is the generation of customized travel directions and maps. These have largely supplanted the traditional use of travel maps where the traveler has the opportunity to access the Internet prior to making a trip. Such products are generally accessible through the Internet. 
         [0003]    With such products, prospective users sign on to the website of the provider and provide their planned travel information. The provider then generates travel directions and/or map information which is returned to the user. This information may then be printed or stored on the hard drive or flash memory of the computer or other device for later retrieval. 
         [0004]    Such systems operate on databases of information compiled by and made available in the United States by the government. For example, databases currently exist where, for each portion of a road or street, many dozens of items of information of a wide array of sorts are available. Such information may include street numbers, speed limits, number of lanes, traffic information, general nature, and so forth. 
         [0005]    Today, numerous devices may be used to download maps and travel directions based on such information. These include conventional personal computers hardwired to the Internet through modems connected to Internet service providers. Likewise, such services may be accessed by handheld devices, such as Blackberry brand handheld communicators, Treo brand handheld e-mail devices, and ultrasmall/ultralight personal computers incorporating wireless communications devices, such as PCMCIA based wireless modules (having substantially wider bandwidth and greater speed as compared to handheld communicators), which are plugged into such personal computers. 
         [0006]    Among the most well-known mapping/travel direction products is that provided under the trademark MapQuest. Using this product, a consumer inputs a starting point for a journey and an ending point. The system generates driving directions including, for example, roads, turning directions, driving distances and drive time. The user is also provided with a map of the route, showing the surrounding area and offering panning and zooming functions. This map may also be stored or printed for later use together with the other materials, for example while driving in an automobile. 
         [0007]    More sophisticated products give the user the opportunity to specify details respecting the route which he or she wishes to travel. 
         [0008]    For example, one popular service allows the user to specify whether he wishes the shortest route or one which takes the least amount of time to travel. Still other websites offering travel direction and mapping services present patrons with more elaborate choices. For example, the Rand McNally website offers the patron selections between 1) fewer steps and more steps (presumably fewer steps being easier to follow and more steps being somewhat shorter), 2) the fastest route or the shortest distance, 3) units in miles or kilometers, and 4) an overview map and destination map, or text-only, or an overview map, step-by-step maps and a destination map, with the option of showing total accumulated distance for each step. 
       SUMMARY OF THE INVENTION  
       [0009]    While such flexibility in the provision of information by travel direction and mapping services is useful, such objective criteria only go so far in assisting travelers in making informed driving choices. For example, drivers are often in the position of having to refer to traffic reports, for example those broadcast on television in map form showing blockages and bad traffic conditions. Ideally, the traveler would then correlate information and, perhaps, break the trip into several segments in an attempt to generate a map without segments with less than tolerable traffic. 
         [0010]    In accordance with the present invention, maps and travel directions are generated, on the basis of subjective criteria input by the user in a mapping and travel direction inquiry, using data comprising objective geographic road data and subjective links to selectable criteria. More particularly, in accordance with the present invention, such subjective criteria are implemented as biases associated with the inventive system&#39;s selection of roads. 
         [0011]    More particularly, in accordance with the invention a method of generating driving direction information, comprises creating a database comprising roads and subjective assessment information, of at least one type, associated with at least some of the roads. A driving direction information request associated with at least one of the subjective assessment information types is received from a requester. Driving direction information based, at least in part, on the subjective assessment information is generated and transmitted to the requester. 
         [0012]    The subjective assessment information includes the identification of the class of the requester. In accordance with the invention, the generation of driving direction information is based more heavily on data collected from individuals of the specified class of requesters. 
         [0013]    The creating of a database is initiated by advertising on a website featuring travel direction information offerings and functionality. 
         [0014]    Positive and negative information is collected with respect to roads. In addition, information may be collected with respect to the reason for which the individual providing the information for the database is traveling on a road being assessed. 
         [0015]    The database may receive information during the same period of time during which it is providing information to users. 
         [0016]    In accordance with the preferred embodiment, information in the database is assigned a lifespan, the information being removed from the database as the lifespan expires. 
         [0017]    In accordance with a preferred environment of the invention, individuals providing information during the creation of the database are queried as toward whether they are motorcycle enthusiasts or families traveling with small children. Requesters of driving directions may specify a road favored by motorcycle enthusiasts or families traveling with small children. 
         [0018]    A requester may specify a number of subjective assessment items to design a driving direction generation function tailored to the requester&#39;s specific needs. Such features may include the requester specifying a starting point and an ending point for a journey. The requester may also specify one or more intermediate points in an itinerary in addition to a starting point and an ending point. 
         [0019]    A requester may also specify a number of subjective assessment items to design a driving direction generation function tailored to the requester&#39;s specific needs. The driving directions are then provided in accordance with such specified subjective assessment items to the extent that statistically sound results can be provided, or, where statistically sound results cannot be provided, the closest statistically sound driving directions are provided instead. In this case, the requester may be informed of the parameters of the driving directions sent to the requester. 
         [0020]    In accordance with a preferred embodiment of the invention, those individuals receiving driving direction information are contacted later for their feedback. This may be done by pop-up e-mails when they next visit the website which provided the driving directions. 
         [0021]    In accordance with one embodiment of the invention, time of day information is obtained from the requester and associated with the assessment information. 
         [0022]    The inventive system may be implemented by biasing speed or distance to reflect any preference, and thus skew an algorithm based on minimizing time of travel or distance traveled respectively.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0029]    Referring to  FIG. 1 , the method  10  of the present invention may begin with a subjective information gathering step  12 . More particularly, information may be gathered by advertising for comments from drivers. Such advertising is done, for example, over the Internet with a pop-up advertisement which says, for example: “Tell us about your favorite road”. Negative information may also be gathered, for example, with a pop-up advertisement which says: “Tell us about the road you never want to be on again!” Alternatively, the ad may simply be an invitation to participate in a survey. In accordance with the preferred embodiment, such advertising would be done on a website which is likely to be related to automobile travel, for example, a website offering maps and directions. 
         [0030]    In response, viewers of the advertisement click on a link on, for example pop up advertisement, to generate a participation request which is received by the system at step  14 . When the system receives such a participation request, it presents to the person responding to the pop-up advertisement a questionnaire which is presented at step  16 . 
         [0031]    The questionnaire may take any one of numerous questionnaire formats known in the art. In accordance with the invention, however, information may be sent to a database as it is received in order that information will be gathered, from forms which are only partially filled out. The system may be programmed to assess the value of the data and use it to the extent it is believed to be valuable, where the data is incomplete. 
         [0032]    In accordance with the invention, it is contemplated that the questionnaire will request data from a survey participant in a number of areas. For example, the system along with requesting road identification data for most favorite and least favorite roads, for example, or perhaps only a most favorite road or roads, or alternatively the most favorite road at step  20 . The system also requests the reason for which the person travels that road at step  20 . This along with vehicle information received at step  22  comprises core information in providing subjective/objective information to individuals requesting travel and mapping information. 
         [0033]    In addition, the system may also request other information which would be useful in providing the subjective/objective travel and mapping information. This may include receiving participant age information at step  34 , receiving gender information at step  36 , receiving information about the type of work a person does at step  38 , and receiving information about the size and nature of the family to which the person responding to the survey belongs at step  40 . 
         [0034]    As the information is accumulated, or after all information has been accumulated, at steps  18 ,  20 ,  22 ,  34 ,  36 ,  38  and  40 , answers are downloaded to database  42 . In accordance with the present invention, it is contemplated that database  42  may contain data which is periodically updated by user inputs. Likewise, in accordance with the invention, information, depending on its nature, is periodically purged. This is done in order to keep the system current and with a maximized utility and reliability. 
         [0035]    Once enough information has been stored in the database at step  42 , appropriate search categories are defined at step  44 . For example, for individuals who ride motorcycles, a search category for motorcycles may be defined. Likewise, if there is a sufficient quantity of data respecting families with children under seven, or under fifteen, such a category may also be defined. 
         [0036]    In accordance with the invention, maps and travel directions are offered at step  46  to users of the system on a screen which includes blanks for the address of the starting point, the address of the destination, and a selection of a route type statistically most favored by, for example, bikers, families traveling with children under seven, or salesman making sales calls. 
         [0037]    In accordance with the invention, it is contemplated that in addition to predefined search categories, as are presented at step  44 , to the extent that data is available, a user can design a search category, and his reason for travel (for example travel to a single point, travel for a scenic drive, travel along a route with attractions for children), the family circumstances associated with the travel, the gender of the driver, and so forth. In addition, the person making a request for map and or travel directions may specify which of the factors in the profile is most important to the user. 
         [0038]    In accordance with the present invention, it is also contemplated that the user will have the option of filling in more than starting point and ending point addresses if the user wishes to make a plurality of stops. 
         [0039]    After an offer of a map and or travel directions is made at step  46 , the same may result in the consumer contacting the website of the operator of the inventive system and sending in a mapping/driving directions request at step  48 . This request, as noted above, includes subjective preference information, such as routes favored by families traveling with small children, routes favored by motorcycle enthusiasts, and so forth. 
         [0040]    After a request for travel directions and/or mapping is received at step  48 , the system proceeds to step  50  where the information in database  42  is consulted. In the event that there is sufficient statistical data, a map can be generated at step  50 , which is precisely tailored to the demographic preferences of the user. Alternatively, it may be a map simply keyed to a particular category, such as roads preferred by motorcycle enthusiasts. The map and/or travel directions are then transmitted at step  52  to the user. 
         [0041]    In accordance with the invention, in order to keep the database up to date, several techniques may be used to continue to gather more information. In addition to optional further advertising at step  12 , the system sends e-mails at step  54  to inquire respecting previously sent information. If the user accepts participation in a follow-up survey the same is received at step  56 . The system then proceeds to present a follow-up questionnaire at step  16  to the user. This follow-up questionnaire does not repeat basic information but is designed to gather information to measure the accuracy of the previously furnished information and the satisfaction of the user with the information presented at step  52 . After presenting the follow-up questionnaire at step  16 , the system proceeds to the information gathering steps in the manner indicated above. 
         [0042]    In addition, the system may present a pop-up follow up message the next time that the user of the service signs on to the website, as indicated at step  58 . Upon receipt of an indication of agreement to participate at step  60 , the system again proceeds to step  16  and presents a follow-up questionnaire. Once again, after presenting the follow-up questionnaire at step  16 , the system proceeds to the information gathering steps in the manner indicated above. 
         [0043]    A system  62 , for implementing the method of the present invention, is illustrated in  FIG. 2 . Generally, a server  64  consults with database  42  and communicates with cyberspace  66  via a modem  68  and Internet service provider  70 . Users, including handheld users  72 , may access the system through their Internet service providers  74 . In principle, the system may also be accessed by texting by a cellular telephone user  76 . However, it is contemplated that the most common user will be based, perhaps at a home or office  78  and using a personal computer  80 , accessing the Internet through a modem connected to the local telephone office  82 , through its Internet service provider  84 . In accordance with the invention, it is also contemplated that users with cellular telephone/portable e-mail service and located in automobiles  86  will also access the system. 
         [0044]    The following are descriptions of alternative embodiments of the invention. For purposes of organization, where possible, corresponding functions or analogous method steps have been given numbers which differ from the embodiment of the invention illustrated in  FIG. 1  by multiples of 100. 
         [0045]    Referring to  FIG. 3 , the method  110  of the present invention may begin with a subjective information gathering step  112 . More particularly, information may be gathered by advertising for comments from drivers. Such advertising is done, for example, over the Internet with pop-up advertisements of suitable content. 
         [0046]    In response, viewers of the advertisement click on the pop-up advertisement to generate a participation request which is received by the system at step  114 . When the system receives such a participation request, it presents to the person responding to the pop-up advertisement a questionnaire which is presented at step  116 . 
         [0047]    The questionnaire may take any one of numerous questionnaire formats known in the art, or as described above. In accordance with the invention, information may be sent to a database as it is received in order that information will be gathered, even in cases where questionnaires are only partially filled out, and the system may be programmed to assess the value of the data and use it to the extent it is believed to be valuable. 
         [0048]    In accordance with the invention it is contemplated that the questionnaire will request data from a survey participant in a number of areas. For example, the system along with requesting road identification data, for example most favorite road at step  118 , will also request reason for travel information at step  120 . This, along with vehicle information received at step  122 , comprises core information in providing subjective/objective information to individuals requesting travel and mapping information. 
         [0049]    In accordance with the invention, information respecting the reason for the good or bad opinion of a particular road is collected at step  124 . For example, the system may present various choices such as traffic, scenery, restaurants, and so forth. This information may then be used to define user map and driving direction categories and provide information to users with various interests, as detailed above. 
         [0050]    Likewise, information input at step  124  may be used to determine the lifespan in the database for the report. For example if the reason for the good opinion is a street carnival, the report should have, for example, only a few days lifespan. If the reason is scenery, then the report should be assigned a lifespan of relatively long duration, for example ten years. Such lifespan is assigned at step  126 . 
         [0051]    In addition, the system may also request other information which would be useful in providing the subjective/objective travel and mapping information. This may include receiving age information at step  134 , receiving gender information at step  136 , receiving information about the type of work a person does at step  138 , and receiving information about the size and nature of the family to which the person responding to the survey belongs at step  140 . 
         [0052]    As the information is accumulated, or after all information has been accumulated, at steps  118 ,  120 ,  122 ,  134 ,  136 ,  138  and  140 , such information is downloaded to a database at step  142 . In accordance with the present invention, it is contemplated that downloading of information to the database at step  142  is dynamic and constantly updated by user inputs. 
         [0053]    Likewise, in accordance with the invention, information, depending on its nature, as detailed above, is periodically purged. This is done to keep the information current and with a maximized utility and reliability. 
         [0054]    Once enough information has been stored in the database at step  142 , appropriate search categories are defined at step  144 . From that point, the use and updating of the databases are analogous and similar to that of the system illustrated in  FIG. 1 , including pop-up follow-up at step  158  and presentation of a questionnaire at step  116 , in response to receipt of a participation agreement at step  160 . 
         [0055]    After an offer of a map and or travel directions is made at step  146 , the same may result in the consumer contacting the website of the operator of the inventive system and sending in a mapping/driving directions request at step  148 . 
         [0056]    After a request for travel directions and/or mapping is received at step  148 , the system proceeds to step  150  where the information in database  142  is consulted to generate a map which is sent at step  152 . 
         [0057]    For example, in addition to optional further advertising a step  112 , the system may send pop-up e-mails at step  154  to inquire respecting the experience of the user. If the user accepts participation in a follow-up survey the same is received at step  156 . The system then proceeds to present a follow-up questionnaire at step  116  to the user. 
         [0058]    The system may present a pop-up follow up message the next time that the user of the direction service signs on to the website as indicated at step  158 . Upon receipt of an indication of agreement to participate at step  160 , the system proceeds to step  116  and presents a follow-up questionnaire. 
         [0059]    Referring to  FIG. 4 , another alternative method  210  in accordance with the present invention may begin with a subjective information gathering step  212 . In response, viewers of an advertisement click on the pop-up advertisement to generate a participation request which is received by the system at step  214 . When the system receives such a participation request, it presents, to the person responding to the pop-up advertisement, a questionnaire which is presented at step  216 . 
         [0060]    The questionnaire may take any one of numerous questionnaire formats known in the art, or as described above. In accordance with the invention, information may be sent to a database as it is received in order that information will be gathered, even in cases where questionnaires are only partially filled out, and the system may be programmed to assess the value of the data and use it to the extent it is believed to be valuable. 
         [0061]    In accordance with the invention, it is contemplated that the questionnaire will request data from a survey participant in a number of areas. For example, the system along with requesting road identification data for example most favorite road at step  218 , will also request reason for travel information at step  220 . This along with vehicle information received at step  222  comprises core information in providing subjective/objective information to individuals requesting travel and mapping information. 
         [0062]    In accordance with the embodiment of the invention illustrated in  FIG. 4 , it is contemplated that the system will determine whether the survey participant falls into one of a number of classes. For example, at step  228  it could determine whether the individual is a motorcycle enthusiast. At step  229 , if the individual is a motorcycle enthusiasts it could query whether the opinion is based on the safety of the road, the scenic value of the road or traffic, for example. 
         [0063]    Similarly, if the individual is not a motorcycle enthusiast, the system will, for example, determine whether it is a family traveling with small children at step  230 . If, at step  230 , it is determined that the respondent is answering for a family traveling with small children, at step  231  the system may put out an inquiry in multiple choice format asking whether the reason for the opinion is the easy availability of rest stops, the scenic nature of the drive, or the convenience of restaurant dining. 
         [0064]    If respondent is not a motorcycle enthusiast or an individual answering for a family traveling with small children, at step  232  the system can determine whether the respondent is in a sales profession. If, at step  232 , it is determined that the respondent is in a sales profession and thus has very different needs from others with respect to a route of travel, at step  233  the system may put out an inquiry in multiple choice format asking whether the reason for the opinion is the convenience of restaurant dining, proximity to towns or quickly moving traffic, as these factors are of interest to, for example, a salesman. 
         [0065]    In accordance with the invention, information respecting other reasons for the good or bad opinion of a particular road is collected at step  224 . Such information is analyzed and organized to be included in user category databases to be querried in response to users in such categories requesting maps and/or directions. For example, the system may present various choices such as traffic, scenery, restaurants, and so forth. This information may then be used to define user map and driving direction categories and provide information to users with various interests, as detailed above. 
         [0066]    Likewise, information input at step  224  may be used to determine the lifespan for the report. Such lifespan is assigned at step  226 . In similar fashion, reasons for the opinion collected from motorcycle enthusiasts, families traveling with small children and salespeople may be assigned a lifespan at step  226   a . When the lifespan for a particular item has run, it is removed from database  242 . 
         [0067]    In addition, the system may also request other information which would be useful in providing the subjective/objective travel and mapping information. This may include receiving age information at step  234 , receiving gender information at step  236 , receiving information about the type of work a person does at step  238 , and receiving information about the size and nature of the family to which the person responding to the survey belongs at step  240 . 
         [0068]    As the information is accumulated, or after all information has been accumulated, at steps  218 ,  220 ,  222 ,  234 ,  236 ,  238  and  240 , the same is downloaded to a database at step  242 . In accordance with the present invention, it is contemplated that downloading of information to the database at step  242  is dynamic and constantly updated by user inputs. Likewise, in accordance with the invention, information, depending on its nature, as detailed above, is periodically purged. This is done in order to keep the information current and with a maximized utility and reliability. 
         [0069]    Once enough information has been stored in the database at step  242 , appropriate search categories are defined at step  244 . From that point, the use and updating of the databases is analogous and similar to that of the system illustrated in  FIG. 1 , including pop-up follow-up advertising at step  258  and presentation of a questionnaire at step  216  in response to receipt of a participation agreement at step  260 . Alternatively, or in addition, a pop-up e-mail to the user of the website may be presented at step  258   a.    
         [0070]    After an offer of map and or travel directions is made at step  246 , the same may result in the consumer contacting the website of the operator of the inventive system and sending in a mapping/driving directions request at step  248 . 
         [0071]    After a request for travel directions and/or mapping is received at step  248 , the system proceeds to step  250 , where the information in database  242  is consulted to generate a map which is sent at step  252 . 
         [0072]    For example, in addition to optional further advertising at step  212 , the system may send pop-up e-mails at step  254  to inquire respecting the experience of the user. If the user accepts participation in a follow-up survey the same is received at step  256 . The system then proceeds to present a follow-up questionnaire at step  216  to the user. 
         [0073]    The system may present a pop-up follow up message the next time that the user of the service signs on to the website as indicated at step  258 . Upon receipt of an indication of agreement to participate at step  260 , the system proceeds to step  216  and presents a follow-up questionnaire. 
         [0074]    In accordance with the present invention, it is also contemplated that the various embodiments of the method of the present invention may also include the collection of data on the time of day that the respondent uses the road and associate the same with the opinion of the road which the individual responding to the questionnaire has provided. This information can then be used to provide a customization opportunity for the person requesting driving directions or a map. For example, the request form for driving directions, in addition to showing the beginning point and endpoint of the journey and all the other information in accordance with the present invention may also include a selection of a time of day for travel, for example, morning rush hour, morning, noon, afternoon, evening rush hour, evening, and after midnight. 
         [0075]    In accordance with the present invention, it is also contemplated that the inventive system may be made available to a particular group, for use only by that particular group. For example, the inventive system may be implemented on a private network. Alternatively, instead of giving a user the option of selecting, for example, shortest route, shortest time or most scenic, the website may include a further selection which says “Proprietary User Sign in”. 
         [0076]    For example, the inventive system may be implemented at a company which provides parcel delivery, such as UPS. If the user clicks “Proprietary User Sign in”, the user may be prompted to input a user-name and password. Once this information has been input by the user and this test has been successfully completed by the user, the user is given access to the system, and to the proprietary database which implements the type of routes which the user&#39;s organization has decided to make available to its, for example, employees. 
         [0077]    The operation of such a proprietary experience-based system may be understood with reference to a parcel delivery service. For example, in such a system, biasing effects implemented by the system may take into account time based information. 
         [0078]    For example, the proprietary information input into the system may be the frequency with which particular roads or streets are traveled at a particular time of the day. In accordance of the present invention it is contemplated that system inputs may be input in an automated fashion, for example, by a computer system which has received package pickup requests as a result of e-commerce over the Internet, or, by way of an alternative example a regular stop request from a particular customer, whether or not packages are present on a particular day to be picked up. Such information may generate bias information on a historical basis as well as generate routing instructions on an ongoing basis. 
         [0079]    More particularly, proprietary information in the database may indicate that a particular portion of a street has business for the parcel service only in the afternoon. Thus, a system input to the effect of requesting a stop at a particular location which experience shows only has business in the afternoon or which is located on a street which is characterized by afternoon business, would result in a route design by the system heavily biased toward stopping at such location or traveling along such street at such a point in the route which is likely to result in such stop being made in the afternoon. 
         [0080]    A similar arrangement may be used by a police department in connection with the answering of calls, where routes in low priority or routine cases would be subjected to modification in response to enterprise specific biases which result in increasing the likelihood of a route output by the system passing through neighborhoods or going down streets or roads, where problems are likely to be encountered, or calls likely to be made requesting police help. 
         [0081]    In accordance with the present invention, it is contemplated that biases may take the form of altering the algorithm determinative parameter. More particularly, map and direction generating systems generally operate by selecting a particular parameter of the dozens of parameters associated with a particular road segment, for operation of the system. For example, if the user wishes to take a minimal mileage route, prior art systems operate on the database of road and street segment information sets by looking at the distance information associated with each particular segment of each road which may be used to generate a user specific route map. 
         [0082]    In accordance with the present invention, this particular parameter may be biased up or biased down. For example, if a road is selected by motorcycle fans 80% of the time, and the system algorithm is based upon lowest mileage, the mileage of the road segment may be decreased to correspond to the degree of favor of motorcycle fans for route map generations input by persons requesting the motorcycle fan&#39;s preference. For example, if 80% of motorcycle fans select a particular road, mileage may be reduced by 20%, while if only 50% of motorcycle fans select a particular road, mileage may only be reduced by 10%, thus skewing a low mileage preference algorithm appropriately. 
         [0083]    Referring to  FIG. 5 , a personalized route map  310  generated by the system is illustrated. Such a route map may be accompanied by written directions or any other sorts of information typically included with maps generated by computer-based systems today. In most respects, map  310  resembles maps generated by prior art systems. In accordance with the invention, however, if a user decides that he or she wishes to rate a particular section of the route, this can be done over the Internet by going to the website of the map provider. In accordance with the invention, the website may provide a menu of previously generated maps upon the user&#39;s signing in or merely going to the website. The user then sees an entry corresponding to the map generated in response to the inquiry which generated the map of  FIG. 5 . 
         [0084]    The user then clicks on that entry and the map illustrated in  FIG. 5  is displayed. If the user wishes to rate a particular segment of the map, the user may use his mouse to drag a box  312  over that portion of the map to be rated. The system then generates a map such as that illustrated in  FIG. 6 . 
         [0085]    The user is then presented with an on-screen button which allows the user to select all portions of the illustrated segment. This may then be rated by the user through the presentation of a series of questions, preferably multiple-choice questions or questions with numerical answers to allow for automated handling of the information. Alternatively, plain English or other language responses may be entered into the system and artificial intelligence used to generate information, assign reliability data to the same and factor the same into selection criteria for future map generation. 
         [0086]    More particularly, it is noted that map segment  314  includes a plurality of interchange points  316 - 328 , and a plurality of road segments  330 - 340 . The option may also be presented to edit a particular boxed map segment such as that illustrated in  FIG. 6 . For example, the right button may be clicked to deselect segments, or to select segments. One possibility is to put a button on the web page which says to “Deselect All Road Segments”, or “Select All Segments”. 
         [0087]    For example, if the user clicked on the button which says “Deselect All Road Segments” and then put the cursor on road segment  338 , and clicked, the display may take the form shown in  FIG. 7  where the segment to be rated, namely segment  338 , is visually emphasized. The left mouse button may be used for such clicking to show a segment to be rated. Alternatively, the user may drag boxes, as illustrated in  FIG. 5  to select subportions of the route. Yet another option is for the right mouse button to be used to unselect portions of a map segment. 
         [0088]    In accordance with the present invention, after the clicking of the button which allows the deselection of all portions of the map, the user may, on a magnified map segment select, for example, portion  338  by using the left mouse button. The result may be a map such as that illustrated in  FIG. 8 . The user is then presented with the questions for rating of portion  238 . After this is completed, the user may unselect portion  338  (by clicking with the right mouse button, for example) and click on portion  332  using the left mouse button to select portion  332 . Upon the entry of a new selection, a dialog box inviting rating of the new selection may be presented. Such dialog boxes include a button to begin the rating process. 
         [0089]    In accordance with the present invention, it is contemplated that the user may continue to adjust the extent of the portion to be rated prior to clicking on the button to begin the rating process. 
         [0090]    Yet another feature of the invention involves the generation of feedback and the presentation of an alternative to the user of the system. For example, if a selected route results in the selection of a street having a tendency toward flooding, such information may be presented to the user. Moreover, if desired, the user may be sent a message indicating the problem and asking if the user wishes an alternative. 
         [0091]    In accordance with a particular preferred embodiment of the invention, extraneous data, such as weather reports, may be used to determine whether the possibility of flood is substantial and thus whether the user should be sent such a message. 
         [0092]    In connection with the above, it is also contemplated that the user will be provided with the opportunity of inputting the date and time of travel and this information may be used, together with weather data, traffic, and the like to determine potential problems and present alternatives to the user in advance. 
         [0093]    Still yet another alternative in accordance with the invention is the receipt of map correction data from individual users. This data may be received by selection of a particular map segment and a user report in words of the correction to the map. 
         [0094]    While only several illustrative embodiments of the invention have been described, it is understood that modifications will be apparent to those of ordinary skill in the art on the basis of the above description and the associated figures. For example, information may be input into the system through the use of global position system (GPS) information or the like. Such modifications are within the spirit and scope of the invention which is limited and defined only by the appended claims.
