  FIG. 4 is a flowchart showing the processing procedure of the control unit 11 related to the accumulation of information. The control unit 11 acquires the detection result information and probe information of the sensor 4 (step S11). And the control part 11 calculates the average travel time of each road link R1, ..., R7, ... based on the acquired sensing result information and probe information (step S12), and stores the calculated average travel time in the storage part 15. It memorizes (Step S13).

  FIG. 5 is a conceptual diagram showing an example of a record layout of the average travel time DB 15b. The average travel time DB 15b has a plurality of columns, for example, a “road link” column for storing IDs of road links R1,..., R7,. The time zone on a weekday is, for example, 24 hours divided by 30 minutes into “10:00 to 10:30”, “10:30 to 11:00”, and so on. Similarly, the time zone on holidays is divided into 24 hours in 30 minute increments. In each row of the average travel time DB 15b, the average travel time in each of the weekday and holiday time zones is stored so as to correspond to each column.

  Next, the control unit 11 receives the brake operation status information (step S14), and stores the received brake operation status information in the storage unit 15 (step S15). Specifically, the control unit 11 receives the position information and the brake operation status transmitted from the in-vehicle device 3 by the communication unit 14. Then, the control unit 11 refers to the clock 16 and identifies the time zone, weekday, and holiday when the brake operation is performed.

The event information can be acquired, for example, by extracting character information and the like related to the event from the web page stored by the web server 6.

  6 and 7 are flowcharts showing the processing procedure of the control units 11 and 21 related to the travel route guidance. The control unit 21 of the car navigation device 2 displays the map information 15a (step S51), and receives the destination using the operation unit 27 (step S52). The map information 15a may be stored in the storage unit 25 of the car navigation device 2 in advance, or the map information 15a transmitted from the route information transmitting device 1 is requested to the route information transmitting device 1 each time. May be received.

  Next, when the destination is received in step S52, the control unit 21 transmits the destination information including the destination information received in step S52 and its own position information to the route information transmitting device 1 through the communication unit 24. (Step S53).

  The control unit 11 of the route information transmitting device 1 receives the destination information and the position information transmitted from the car navigation device 2 by the communication unit 14 (step S54). Next, the control unit 11 searches for a travel route from the current location indicated by the received position information to the destination indicated by the destination information (step S55). Here, the shortest route from the current location to the destination may be searched. Then, the control unit 11 causes the communication unit 14 to transmit traveling route information indicating the searched traveling route to the car navigation device 2 (step S56).

  The control unit 21 of the car navigation device 2 receives the traveling route information transmitted from the route information transmitting device 1 by the communication unit 24 (step S57). Then, the control unit 21 displays the traveling route on the map based on the received traveling route information (step S58), and executes the guidance processing of the traveling route (step S59).

  FIG. 8 is a schematic view showing an example of a map image displaying a travel route. The map image includes an image of the road R on which the vehicle B heading for the destination travels and an image of a building around the road R. In addition, a travel route image 7 showing a travel route as a diagram is superimposed on the map image. One end of the travel route image 7 corresponds to the travel position of the vehicle B, and the image of the vehicle B is superimposed on the one end. The other end of the travel route image 7 corresponds to the destination, and an image indicating the destination, for example, an arrow image is superimposed thereon.

  The control unit 11 of the route information transmitting apparatus 1 that has transmitted the traveling route information calls a subroutine related to the search of the alternative traveling route, and searches for the alternative traveling route (step S60).

  FIGS. 9 and 10 are flowcharts showing the processing procedure of a subroutine related to the search of the alternative travel route, and FIG. 11 is an explanatory view conceptually showing the method of searching the alternative travel route. The control unit 11 performs congestion prediction on the traveling route being guided (step S91), and determines the presence or absence of the possibility of congestion on the traveling route (step S92). For example, based on the time when the vehicle B travels on a certain road link R1,..., R7,... And the average travel time stored in the average travel time DB 15b, the control unit 11 determines the average travel time of the travel route at that time, and By comparing the average travel time in other time zones, traffic congestion on the travel route is predicted. For example, when the average travel time of the travel route at the time is α times the average total travel time, it is determined that there is a possibility of congestion. α is an arbitrary value and can be arbitrarily set by the user.

  When it is determined that there is a possibility of traffic jam (step S92: YES), the control unit 11 searches for one or a plurality of alternative travel routes (step S103), and ends the subroutine processing. The alternative travel route need not be the shortest route. For example, referring to the average travel time DB 15b, if a travel route composed of road links R1,..., R7,. good. However, β is smaller than α. The value of β may also be set arbitrarily by the user. When there are a plurality of alternative travel routes that do not cause traffic jams, the control unit 11 further travels such that there are few people within the predetermined range of the alternative travel routes, no events are held, and there are few accidents. Select a route. In this way, the control unit 11 searches for a safe travel route as an alternative travel route without causing traffic congestion. As an alternative travel route, when there is a margin before the departure time, another time zone that is not crowded may be recommended, or public transportation instead of a car may be recommended.

  When it is determined in step S92 that there is no possibility of traffic jam (step S92: NO), the control unit 11 specifies the total number of brakes of the vehicle B traveling on the traveling route being guided (step S93). It is determined whether the number of brakes is equal to or greater than a specific number (step S94). The specific number of times may be set to, for example, a predetermined multiple of the average number of times of braking in the traveling route under guidance or a part of the road links R1, ..., R7, ... of the traveling route. The average number of times of braking is an average value of the number of times of braking in each time zone in the travel route or part of the road links R1,..., R7,.

  When it is determined that the total number of brakes is equal to or greater than the specific number of times (step S94: YES), the control unit 11 searches for one or a plurality of alternative travel routes (step S103) and ends the subroutine processing. When it is determined that the total number of brakes is less than the specific number of times (step S94: NO), the control unit 11 refers to the person position information DB 15d, as shown by an ellipse in FIG. The number of persons A existing within a predetermined range including a part of the travel route is specified (step S95). Then, the control unit 11 determines whether the number of persons A present in the predetermined range is equal to or more than the specific number (step S96). That is, the control unit 11 determines whether or not the number of GPS portable communication devices 5 existing within the predetermined number is equal to or greater than a specific number.

  When it is determined that the number of persons A existing within the predetermined range is greater than or equal to the specific number (step S96: YES), the control unit 11 searches for one or a plurality of alternative travel routes (step S103). Finish the process. When it is determined that the number of persons A is less than the specific number (step S96: NO), the control unit 11 refers to the accident information DB 15e and identifies past accidents that have occurred on the route being guided (step S97). Then, it is determined whether or not there has been a predetermined number of accidents within a certain past period on the travel route (step S98).

  When it is determined that there have been a predetermined number of accidents within a certain past period (step S98: YES), the control unit 11 searches for one or a plurality of alternative travel routes (step S103), and ends the subroutine processing. When it is determined that the number of accidents within the past certain period is less than the predetermined number (step S98: NO), the control unit 11 refers to the event information DB 15f, or the traveling route being guided or the traveling route The number of events to be performed within a predetermined range including a part of the number is specified (step S99).

  And the control part 11 determines the presence or absence of the event performed within the said predetermined range (step S100). When it is determined that there is an event to be performed within the predetermined range (step S100: YES), the control unit 11 searches for one or a plurality of alternative travel routes (step S103) and ends the subroutine processing.

  When it is determined that there is no event to be performed within the predetermined range (step S100: NO), the control unit 11 specifies the number of other vehicles B scheduled to travel on the traveling route being guided (step S101). Then, the control unit 11 determines whether the number of other planned vehicles to travel on the traveling route being guided is equal to or greater than a specific number (step S102). When it is determined that the number of other planned traveling vehicles is less than the specific number (step S102: NO), the control unit 11 determines that the alternative travel route search is unnecessary, does not perform the alternative travel route search, Finish the process. When it is determined that the number of other scheduled traveling vehicles is equal to or greater than the specific number (step S102: YES), the control unit 11 searches for one or a plurality of alternative travel routes (step S103) and ends the subroutine processing.

  Returning to FIG. 6, the processing after step S61 will be described. After completing the process in step S60, the control unit 11 determines whether there is an alternative travel route based on the process result in step S60 (step S61). When it determines with there being an alternative travel route (step S61: YES), the control part 11 transmits the alternative travel route information which shows an alternative travel route to the car navigation apparatus 2 in the communication part 14 (step S62).

  Next, the control unit 21 of the car navigation device 2 receives the alternative travel route information at the communication unit 24 (step S63). Then, the control unit 21 displays the alternative traveling route on the map based on the received alternative traveling route information (step S64), and receives the alternative operation of the traveling route (step S65).

  FIG. 12 is a schematic diagram illustrating an example of a map image displaying an alternative travel route. By the process of step S64, in addition to the current traveling route image 7, alternative traveling route images 81 and 82 in which one or more alternative traveling routes are graphically represented are superimposed on the map. In the process of step S <b> 65, for example, the control unit 21 accepts substitution of a traveling route by accepting a pointing operation of the alternative traveling route images 81 and 82 at the operation unit 27.

  Next, the control unit 21 determines whether or not a travel route alternative operation has been performed (step S66). When it determines with alternative operation having been performed (step S66: YES), the control part 11 detects an own position, and determines whether the vehicle B is drive | working the alternative travel route (step S67). When it determines with driving | running | working on an alternative driving route (step S67: YES), the control part 11 shows the driving result information and the identification information of the car navigation apparatus 2 which show that the vehicle B is driving | running an alternative driving route. Then, the communication unit 14 transmits the information to the route information transmitting device 1 (step S68).

  The control unit 11 of the route information transmitting device 1 receives the travel result information and the identification information transmitted from the car navigation device 2 at the communication unit 14 (step S69), and determines the contribution points according to the received travel result information. Processing to be given to the user B is performed (step S70). The user can specify the identification information.

  The contribution points are given by, for example, the degree to which the numerical values of various DBs in one or more road links R1,..., R7,. Taking the average travel time as an example, it is assumed that the value estimated to take about 50 seconds in the past statistics has been improved to about 35 seconds in the time zone in which the alternative travel route is proposed. The degree of improvement is calculated as, for example, 50/35 ≒ 1.43 points. For road links R1,..., R7,... That have been determined to be dangerous due to the number of sudden braking operations, the degree of contribution is calculated according to the degree of improvement in the total number of brakes stored in the brake operation status DB 15c. The degree of contribution is similarly calculated according to the degree of improvement of the numerical values of the person position information DB 15d, the accident information DB 15e, and the event information DB 15f that store information related to other traffic jams and dangers. And the control part 11 adds up all the contribution degrees, and makes the added value the contribution point.

  FIG. 13 is a conceptual diagram of the contribution point table. The storage unit 15 stores a contribution point table. The contribution point table has a plurality of columns, for example, a "user ID" column, an "apparatus ID" column, a "contribution point" column, and an "alternative route benefit use count" column. The “alternative route privilege use count” column is further classified into a “restaurant” column, a “fashion” column, and a “miscellaneous goods” column according to the type of privilege. The “user ID” column stores a user ID for identifying the user, and the “device ID” column stores identification information of the car navigation device 2 used by the user. In addition, the number of times of use of the privilege is stored in the “number of times of use of the alternative route privilege” for each type of privilege used by the user in the past. The control unit 11 stores the contribution point calculated in step S70 in the contribution point table in association with the identification information received in step S69.

FIG. 14 is a schematic diagram showing a map image on which a coupon image is displayed.
Furthermore, a coupon image 9 may be displayed in the vicinity of the alternative travel route image 81 to provide a stronger incentive for the user to select an alternative travel route. As the coupon image 9, the coupon image 9 corresponding to the type of privilege that is frequently used by the user may be selectively displayed. The types of benefits that are frequently used by the user can be identified by referring to the contribution point table.
When the information is accumulated in the contribution point table, the alternative traveling route may be searched using the information of the contribution point table. That is, you may comprise so that the alternative driving | running | working path | route which the shop which provides the same kind of service or goods with many use frequency | counts by a user exists in the periphery may be selected preferentially. By proposing an alternative travel route in which a store that provides goods and services desired by the user or a privilege exists, the user can be given a stronger incentive to select an alternative travel route.

In addition, non-life insurance premiums may be returned according to the contribution points.
FIG. 15 is a conceptual diagram of an insurance premium table. The insurance premium table is a table in which contribution points are associated with insurance premiums for each vehicle type. The user can receive insurance premiums according to the contribution points, and can give the user an incentive to select an alternative travel route. With this incentive, it is possible to more effectively alleviate traffic congestion and reduce the risk of travel routes.

  Next, the control unit 11 causes the communication unit 14 to transmit reception confirmation information including the information of the contribution point given in step S70 to the car navigation device 2 (step S71).

  The control unit 21 of the car navigation device 2 receives the reception confirmation information transmitted from the route information transmitting device 1 (step S72). Then, the control unit 21 displays the reception result on the display unit 26 based on the received reception confirmation information (step S73). For example, the control unit 21 displays the given contribution points on the map.

  Next, when it is determined in the above-described processing that there is no alternative travel route (step S61: NO), the control unit 21 does not perform an alternative operation for the travel route (step S66: NO), and the vehicle B is alternative travel. When it is determined that the vehicle is not traveling on the route (step S67: NO), or when the process of step S73 is completed, the control unit 21 detects its own position information, and whether or not the vehicle B has arrived at the destination. It is determined (step S74). When it determines with the vehicle B not having arrived at the destination (step S74: NO), the control part 11 returns a process to step S59. When it determines with the vehicle B having arrived at the destination (step S74: YES), the control part 11 finishes a process.

  According to the car navigation system, the car navigation device 2, and the route information transmitting device 1 configured as described above, an alternative travel route that can avoid traffic congestion or danger compared to the shortest travel route is proposed, and the user can The fact that the vehicle has traveled along the travel route can be confirmed.

In addition, by configuring to contribute points when traveling on a user alternative travel route, the user is given an incentive to select an alternative travel route, more effectively alleviating traffic congestion, and reducing the risk of the travel route. Can be reduced.
For example, according to the contribution point, the user can receive the insurance premium corresponding to each period, and displays, for example, a coupon image 9 of a type that the user uses frequently according to the number of times of use of the benefits of the alternative travel route. By doing so, an incentive to select an alternative travel route can be given to the user. Therefore, it is possible to alleviate traffic congestion more effectively and reduce the risk of the travel route.

  Furthermore, by having the user use an alternative travel route in which the vehicle B travels relatively little, a business opportunity can be provided in the vicinity of the alternative travel route.
