The absolute road attribute information usually indicates the attribute of the road on which the mobile object has traveled.

  The relative road attribute information is road attribute information indicating a difference between two or more absolute road attribute information having the same attribute. In addition, the difference is, for example, a result of comparison between one absolute road attribute information and another absolute road attribute information, a difference between one absolute road attribute information and another absolute road attribute information, For example, a difference between one absolute road attribute information and another absolute road attribute information.

  In addition, the relative road attribute information usually includes one or more absolute road attribute information indicating the attribute of the road on which the mobile object has traveled, and one or more absolute road attribute information indicating the attribute of the road on which the mobile object has not traveled. It is the information which shows the difference. The “road on which the moving body did not travel” is a road on the route from the departure place to the destination, and is a road different from the road on which the moving body traveled.

  Note that the above difference does not matter which absolute attribute information is the difference. That is, the difference may be a difference between one or more absolute road attribute information indicating the attribute of the road on which the mobile object has not traveled with respect to one or more absolute road attribute information indicating the attribute of the road on which the mobile object has traveled. The difference may be a difference in one or more absolute road attribute information indicating the attribute of the road on which the mobile object has traveled with respect to one or more absolute road attribute information indicating the attribute of the road on which the mobile object has not traveled.

  Further, (d) shows, for example, the type of road that did not travel, the structure of the road, and the like. That is, (d) is usually negative of absolute road attribute information. (D) is, for example, “unused: type: highway”, “unused: type: general road”, “unused: structure: tunnel”, “unused: structure: bridge”, and the like. Note that (d) may indicate the width of a road that has not traveled, the number of traffic signals on the road, the number of lanes on the road, the speed limit on the road, and the like.

  The relative road attribute information (a) to (d) above includes (1) relative road width information indicating a difference in road width information and (2) traffic for each road attribute indicated by the relative road attribute information.

The information includes, for example, “not running”, “not used”, “not used”, and the like.

  The reception unit 113 receives current position information or a route generation instruction from the terminal device 12. The current position information is position information indicating the current position of the terminal device 12. The route generation instruction is an instruction for generating route information indicating a route to the destination. Further, the current position information and the route generation instruction are usually associated with a terminal identifier for identifying the terminal device 12. The terminal identifier is usually an arbitrary ID or the name of the terminal device 12, but may be a user ID for identifying a user who uses the terminal device 12.

  Further, the route generation instruction usually includes departure place information indicating a departure place and destination information indicating a destination. In addition, the route generation instruction may have route point information indicating a route point. The departure point information, destination information, and waypoint information are usually point information indicating points. The point information includes, for example, point position information which is position information indicating the position of the point on the map, point name information indicating the name of the point on the map, a point identifier for identifying the point, and the like.

  For the map information stored in the map information storage unit 111, the route information generation unit 114 includes one or more traveling road attribute information stored in the road attribute information storage unit 112 and the route received by the reception unit 113. The departure point information included in the generation instruction and the destination information included in the route generation instruction are applied. In addition, when the route generation instruction includes route point information, the route information generation unit 114 also applies the route point information to the map information.

  “Apply departure point information to map information” means that a point on the map indicated by the departure point information is set as a departure point. “Applying destination information to map information” means that a point on the map indicated by the destination information is a destination. Further, “applying the traveling road attribute information to the map information” means selecting a road on the map that matches the traveling road attribute information as a route. Further, “apply route point information to map information” means that a point on the map indicated by the route point information is set as a route point. Further, since the route search is publicly known, detailed description thereof is omitted.

  Then, the route information generation unit 114 searches for one or more routes that are one or more routes from the departure point to the destination, and that matches the one or more traveling road attribute information, and displays one or more routes indicating the respective routes. Generate route information. The route information usually includes one or more road information.

  “A route suitable for the traveling road attribute information” is usually a route having only a road corresponding to the traveling road attribute information, but is a route having at least one road corresponding to the traveling road attribute information. Also good. The “road corresponding to the road attribute information” is a road that matches the travel road attribute information, and is a road indicated by the road information having the travel road attribute information. The route information usually includes one or more road information.

  For example, when the traveling road attribute information is relative road attribute information, the route information generation unit 114 normally searches for one or more routes from the departure point to the destination, and includes the relative road attribute information in the route. Select a matching route. For example, when the relative road attribute information is the relative traffic signal number information “number of signals: small”, the route information generation unit 114 normally searches for two or more routes from the departure point to the destination, Select the path with the least number of signals. In this case, for example, the route information generation unit 114 searches for two or more routes from the departure point to the destination, and selects a route having a number of signals equal to or less than a predetermined number from the routes. Also good. In this case, for example, the route information generation unit 114 searches for two or more routes from the departure point to the destination, and selects a predetermined number of routes in the order from the smallest number of signals. May be.

  In general, in route search, a route from a departure point to a destination is searched in consideration of the cost (time, distance, fuel consumption, fee, etc.) of a road between points (nodes) on the map. Therefore, for example, when the traveling road attribute information is relative road attribute information, the route information generation unit 114 may perform a route search by changing the cost according to the relative road attribute information.

  For example, it is assumed that the relative road attribute information is relative traffic signal number information “number of signals: small”. In this case, for example, when there are two or more road options at one point, the route information generation unit 114 compares the traffic signal numbers of the two or more roads, and the smaller the traffic signal number, the lower the cost of the road. The route search may be performed by reducing the cost so that the decrement increases. For example, assume that there are two roads A and B at one point. Then, it is assumed that the number of traffic signals on each of the two roads is “10” and “15”. In this case, the route information generation unit 114 compares the two traffic signal numbers, and reduces the cost of “10” roads A, which is the smaller, to be smaller than the cost of the roads B.

  For example, it is assumed that the relative road attribute information is relative road width information “width: wide”. In this case, for example, when there are two or more road options at one point, the route information generation unit 114 compares the road widths of the two or more roads. The wider the road width, the lower the cost of the road. The cost may be reduced and the route search may be performed so that becomes larger. For example, assume that there are two roads A and B at one point. The road widths of the two roads are “8 m” and “6 m”. In this case, the route information generation unit 114 compares the widths of the two roads, and reduces the cost of the wider “8 m” road A so as to be smaller than the cost of the road B.

  Further, for example, it is assumed that the relative road attribute information is relative road type information “use: general road”. In this case, for example, when there are two or more road options at one point, the route information generation unit 114 causes the cost of a road that is a general road among the two or more roads to be smaller than the cost of other roads. Alternatively, the cost may be increased and a route search may be performed.

  Further, for example, it is assumed that the relative road attribute information is relative road type information “not used: highway”. In this case, for example, when there are two or more road options at one point, the route information generation unit 114 causes the cost of a road that is a highway among the two or more roads to be higher than the cost of other roads. Alternatively, the cost may be increased and a route search may be performed.

  Further, the route information generation unit 114 counts, for example, the number of relative road attribute information stored in the road attribute information storage unit 112 for each road attribute indicated by the relative road attribute information, and according to the number The cost may be increased or decreased. That is, the route information generation unit 114 determines a cost reduction coefficient (weight) based on the relative road attribute information according to the number of relative road attribute information stored in the road attribute information storage unit 112, for example. May be. For example, it is assumed that the relative road attribute information is relative road type information “use: general road” and relative road width information “width: wide”, and the numbers are “10” and “8”. In this case, the number of relative road type information is larger than the number of relative road width information. Therefore, the route information generation unit 114 reduces the cost of each road so that the cost reduction by the relative road type information is larger than the cost reduction by the relative road width information, for example. For example, the route information generation unit 114 first sorts the roads as options in the order of narrowness. Then, the route information generation unit 114 reduces the cost of each sorted road in order so that the cost reduction increases (for example, increases by 1) as the width increases. At this time, the decrement when the cost was reduced last is held. Then, the route information generation unit 114 reduces the cost by decrementing “+1” to the decrement retained for the road that is an ordinary road among the roads as options.

  That is, when the cost of the road between points is changed according to the relative road attribute information, the route information generation unit 114 selects the road that matches the difference indicated by the relative road attribute information as described above. Increase or decrease costs.

  For example, when the traveling road attribute information is relative road attribute information, the route information generation unit 114 may perform a route search using the relative road attribute information as the cost. For example, it is assumed that the relative road attribute information is relative traffic signal number information “number of signals: small”. In this case, for example, the route information generation unit 114 uses the traffic signal number information as the cost of a road between points, and searches for a route that minimizes the cost. For example, it is assumed that the relative road attribute information is relative road width information “width: wide”. In this case, for example, the route information generation unit 114 uses the road width information as the cost of a road between points, and searches for a route having the maximum cost.

  Note that the route search method and procedure are the same for other relative road attribute information, and a description thereof will be omitted.

  For example, when the traveling road attribute information is absolute road attribute information, the route information generation unit 114 normally selects a road that matches the absolute road attribute information and performs a route search. For example, when the absolute road attribute information is road width information “6 m”, the route information generation unit 114 normally selects a road having a road width of “6 m” and performs a route search. In this case, the route information generation unit 114 may perform route search by selecting at least one road having a road width of “6 m”, for example. In this case, the route information generation unit 114 may perform a route search so that, for example, a road having a road width of “6 m” is half or more of a road in the route. Further, the “6 m” may be, for example, “6 m or more”, “6 m or less”, or “around 6 m”. In addition, a threshold for determining whether or not “before and after” is usually determined in advance.

  Note that the route search method and procedure are the same for other absolute road attribute information, and the description thereof will be omitted.

  For example, when the road attribute information storage unit 112 stores absolute road attribute information and relative road attribute information having the same attribute, the route information generation unit 114 normally uses one of the traveling road attribute information. . Also, which traveling road attribute information is used is usually determined in advance.

  For example, in a situation where road width information “10 m” and relative road width information “wide” are stored in the road attribute information storage unit 112, a road with a road width of “9 m” and a road width of “12 m” Suppose you select one of the roads. In this case, for example, when the road width information is used, the route information generation unit 114 calculates the difference between the road width information “10 m” and the width of the road of the option, and the road width with a small difference is “9 m”. Select the road. Further, for example, when using the relative road width information, the route information generation unit 114 compares the road widths of the options and selects the road having the wide road width of “12 m”.

  In addition, the route information generation unit 114 normally searches for a route that matches the travel road attribute information using the travel road attribute information corresponding to the terminal identifier included in the route generation instruction received by the reception unit 113.

  In addition, the route information generation unit 114 may calculate an average of one or more traveling road attribute information stored in the road attribute information storage unit 112 and search for a route that matches the average. In addition, the route information generation unit 114 counts the number of the same attribute of the traveling road attribute information stored in the road attribute information storage unit 112, for example, and matches the traveling road attribute information having the largest number. A route may be searched. For the calculation of the average or the maximum number of traveling road attribute information, for example, all the traveling road attribute information stored in the road attribute information storage unit 112 may be used, or traveling within a predetermined period of time may be used. Road attribute information may be used. The period is, for example, one month before the day for performing the route search, one year before the day, a month including the day, the same month as the month including the day, or the like. Moreover, although the said period is usually decided beforehand, it may not be so.

  That is, the route information generation unit 114 statistically processes the history of one or more traveling road attribute information stored in the road attribute information storage unit 112, and uses the traveling road attribute information that is a result of the statistical processing to perform a route search. May be performed. The statistical processing may be performed, for example, every time the reception unit 113 receives current position information (immediately after the reception), or every time the reception unit 113 receives a route generation instruction (immediately after the reception). Or every time the road attribute information accumulation unit 116 accumulates road attribute information (immediately after the accumulation), and the timing is not limited.

  Moreover, as long as the traveling road attribute information used by the route information generation unit 114 for the route search is traveling road attribute information corresponding to the terminal identifier included in the route generation instruction received by the reception unit 113, any traveling road attribute information is possible. It does not matter whether information is used. The route information generation unit 114 only needs to be able to search for a route that matches the travel road attribute information, and any search method or procedure may be used.

  The road attribute information acquisition unit 115 acquires one or more traveling road attribute information. The road attribute information acquisition unit 115 normally acquires one or more traveling road attribute information by means described below.

  The road attribute information acquisition unit 1151 acquires one or more absolute road attribute information indicating the attribute of the road on which the mobile object has traveled. The road attribute information acquisition unit 1151 normally acquires road information corresponding to the current position information received by the reception unit 113 from the map information stored in the map information storage unit 111. At this time, for example, the road attribute information acquisition unit 1151 may acquire road information corresponding to the current position information every time the reception unit 113 receives the current position information, or the current information received by the reception unit 113. The position information may be accumulated in an arbitrary storage area, and road information corresponding to the accumulated current position information may be acquired at each predetermined timing. That is, the road attribute information acquisition unit 1151 may acquire the absolute road attribute information corresponding to the current position information received by the reception unit 113 from the map information storage unit 111, and the acquisition timing is not limited.

  Note that the type of absolute road attribute information acquired by the road attribute information acquisition unit 1151 may or may not be predetermined.

  The non-running route information generating unit 1152 has the departure point information included in the route generation instruction received by the receiving unit 113 and the purpose information included in the route generation instruction with respect to the map information stored in the map information storage unit 111. Apply. In addition, when the route generation instruction includes route point information, the route information generation unit 114 also applies the route point information to the map information. Then, the non-running route information generating unit 1152 searches for two or more routes to the destination, and obtains one or more pieces of route information indicating one or more routes in which the moving body did not travel among the two or more routes. Generate.

  The non-running route information generating unit 1152 applies various information to the map information as described above, searches for one or more routes to the destination, and indicates the one or more routes. One or more pieces of route information may be generated. In this case, normally, the generated route information includes route information indicating a route on which the mobile object has not traveled.

  In addition, when generating the one or more route information, the non-running route information generating unit 1152 is, for example, when the moving body has arrived at the destination or while the moving body is traveling toward the destination. In addition, the route information is generated. Further, when the two or more pieces of route information are generated, the non-running route information generation unit 1152 is configured such that, for example, when the moving object leaves the destination or when the moving object arrives at the destination, the moving object The route information is generated while traveling toward the road.

  The relative road attribute information acquisition unit 1153 includes one or more pieces of absolute road attribute information acquired by the road attribute information acquisition unit 1151 and one or more route information generated by the non-running route information generation unit 1152. One or more relative attribute information indicating a difference from the absolute road attribute information is acquired.

  For example, when the non-running route information generation unit 1152 generates one or more pieces of route information, the one or more pieces of route information do not include route information indicating a route that the mobile object has not traveled. Therefore, the relative road attribute information acquisition unit 1153 includes one or more absolute road attribute information acquired by the road attribute information acquisition unit 1151 and one or more route information indicating a route on which the mobile body did not travel. One or more relative attribute information indicating a difference from the absolute road attribute information is acquired.

  Further, for example, when the non-running route information generating unit 1152 generates two or more pieces of route information, the two or more pieces of route information include route information indicating a route in which the mobile object has not traveled. Therefore, the relative road attribute information acquisition unit 1153 uses the one or more absolute road attribute information acquired by the road attribute information acquisition unit 1151, and each of the two or more route information indicates a route on which the mobile object has not traveled. It is determined whether it is route information. Then, the relative road attribute information acquisition unit 1153 includes one or more absolute road attribute information acquired by the road attribute information acquisition unit 1151 and one or more route information indicating a route on which the mobile body did not travel. One or more relative attribute information indicating a difference from the absolute road attribute information is acquired.

  Moreover, the relative road attribute information acquisition unit 1153 normally acquires a difference between two or more absolute road attribute information having the same attribute as relative road attribute information.

  For example, when the absolute road attribute information is a numerical value, the relative road attribute information acquisition unit 1153 normally calculates a difference between the numerical values and acquires relative road attribute information corresponding to the difference. In this case, the relative road attribute information acquisition unit 1153 normally holds a correspondence table between the sign of the difference and the relative road attribute information, and acquires the relative road attribute information based on the correspondence table.

  For example, it is assumed that the relative road attribute information acquisition unit 1153 holds a correspondence table of “positive: wide | negative: narrow”. Further, it is assumed that the road attribute information acquisition unit 1151 acquires the road width information “6 m”, and the route information generated by the non-running route information generation unit 1152 has the road width information “4 m”. In this case, the relative road attribute information acquisition unit 1153 calculates “6-4 = + 2”, and acquires relative road attribute information “road width: wide” from the correspondence table. Further, it is assumed that the road attribute information acquisition unit 1151 acquires the road width information “6 m”, and the route information generated by the non-running route information generation unit 1152 has the road width information “8 m”. In this case, the relative road attribute information acquisition unit 1153 calculates “6-8 = −2”, and acquires relative road attribute information “road width: narrow” from the correspondence table.

  Also, for example, it is assumed that the road attribute information acquisition unit 1151 acquires road width information “6 m”. Further, it is assumed that the non-running route information generation unit 1152 generates three route information, and each of the three route information has road width information “4 m”, “6 m”, and “5 m”. In this case, for example, the relative road attribute information acquisition unit 1153 first calculates an average “(4 + 6 + 5) ÷ 3 = 5” of road width information included in each of the three route information. Then, the relative road attribute information acquisition unit 1153 calculates a difference “6-5 = + 1” between the road width information “6 m” acquired by the road attribute information acquisition unit 1151 and the average road width information “5 m”. The relative road attribute information “road width: wide” is acquired from the above correspondence table.

  For example, when the absolute road attribute information is other than a numerical value, the relative road attribute information acquisition unit 1153 acquires, for example, the absolute road attribute information acquired by the road attribute information acquisition unit 1151 as the relative road attribute information. Further, the relative road attribute information acquisition unit 1153 may acquire, for example, absolute road attribute information included in the route information generated by the non-running route information generation unit 1152 as the relative road attribute information.

  For example, it is assumed that the road attribute information acquisition unit 1151 acquires road type information “highway”, and the route information generated by the non-running route information generation unit 1152 has road type information “general road”. In this case, the relative road attribute information acquisition unit 1153 compares the two road type information, for example, and determines whether or not they are different. Since the two road type information is different, the relative road attribute information acquisition unit 1153 acquires the road type information “highway” acquired by the road attribute information acquisition unit 1151.

  Further, for example, it is assumed that the road attribute information acquisition unit 1151 acquires road type information “highway”. Further, it is assumed that the non-running route information generating unit 1152 generates three route information, and each of the three route information includes road type information “general road”, “general road”, and “highway”. . In this case, the relative road attribute information acquisition unit 1153, for example, first acquires the road type information “general road” that is the most among the road type information included in each of the three route information. Then, the relative road attribute information acquisition unit 1153 compares the road type information acquired by the road attribute information acquisition unit 1151 with the most frequently used road type information, and determines whether or not they are different. Since the two road type information is different, the relative road attribute information acquisition unit 1153 acquires the road type information “highway” acquired by the road attribute information acquisition unit 1151.

  Further, for example, it is assumed that the road attribute information acquisition unit 1151 acquires road type information “general road”. Further, it is assumed that the non-running route information generating unit 1152 generates three route information, and each of the three route information includes road type information “highway”, “highway”, and “highway”. . This indicates that the user has headed using a general road to a destination that is normally headed using a highway, for example. Therefore, in such a case, for example, the relative road attribute information acquisition unit 1153 first acquires the road type information “highway” which is the most among the road type information included in each of the three route information. Then, the relative road attribute information acquisition unit 1153 compares the road type information acquired by the road attribute information acquisition unit 1151 with the most frequently used road type information, and determines whether or not they are different. Since the two road type information is different, the relative road attribute information acquisition unit 1153 acquires the road type information “highway” included in the route information generated by the non-running route information generation unit 1152. Then, the relative road attribute information acquisition unit 1153 gives information indicating that the road type information is not used to the acquired road type information, and acquires, for example, “unused: highway”.

  In addition, about the other relative road attribute information which is a numerical value, since the acquisition method, procedure, etc. are the same as the above, description is abbreviate | omitted. Also, with respect to other relative road attribute information other than numerical values, the acquisition method and procedure are the same as described above, and thus the description thereof is omitted.

Also, for example, it is assumed that the road attribute information acquisition unit 1151 acquires road width information “8 m”, road type information “general road”, and traffic signal number information “12”. Further, it is assumed that the non-travel route information generation unit 1152 generates three route information, and each of the three route information has the following absolute road attribute information.
(1) Road width information “4 m”, road type information “general road”, traffic signal number information “11”
(2) Road width information “6 m”, road type information “general road”, traffic signal number information “6”
(3) Road width information “5 m”, road type information “general road”, traffic signal number information “8”
In this case, the relative road attribute information acquisition unit 1153 performs the same processing as described above, and acquires three pieces of relative road attribute information “road width: wide”, “road type: unquestioned”, and “traffic light: many”.

  As described above, the relative road attribute information acquisition unit 1153 includes, for example, the absolute road attribute information included in the absolute road attribute information acquired by the road attribute information acquisition unit 1151 and the route information generated by the non-running route information generation unit 1152. A difference from the average may be obtained.

  Also, the relative road attribute information acquisition unit 1153 is, for example, the largest of the absolute road attribute information included in the absolute road attribute information acquired by the road attribute information acquisition unit 1151 and the route information generated by the non-running route information generation unit 1152. The difference from the road attribute information may be acquired.

  Further, the relative road attribute information acquisition unit 1153 statistically calculates, for example, the absolute road attribute information acquired by the road attribute information acquisition unit 1151 and all the absolute road attribute information included in the route information generated by the non-running route information generation unit 1152.

  The type of relative road attribute information acquired by the relative road attribute information acquisition unit 1153 may or may not be determined in advance. The relative road attribute information acquisition unit 1153 also has one or more absolute information included in the one or more route information generated by the non-running route information generation unit 1152 with respect to the one or more absolute road attribute information acquired by the road attribute information acquisition unit 1151. What is necessary is just to be able to acquire the difference in road attribute information, and the acquisition method and procedure are not limited.

Then, the terminal accepting unit 123 accepts a route generation instruction that is an instruction to generate a route with the point x in FIG. 8 as the departure point and the same point b as the destination. The route generation instruction includes departure point information indicating the point x and destination information indicating the point b.

  Next, the terminal transmission unit 124 transmits the route generation instruction received by the terminal reception unit 123 to the server in association with the terminal identifier “NAVI001” stored in the terminal identifier storage unit 121.

  Next, the reception unit 113 of the server receives the above route generation instruction associated with the terminal identifier “NAVI001”.

  Next, the route information generation unit 114 acquires the terminal identifier “NAVI001” associated with the route generation instruction. At this time, if absolute road attribute information and relative road attribute information having the same attribute exist, the relative road attribute information is acquired. Then, the route information generation unit 114 acquires relative road attribute information from “ID = 014” to “ID = 016” in FIG. 7, which is relative road attribute information corresponding to the terminal identifier.
