<Bicycle usage history information collection operation>
Next, the operation of the bicycle use history information collection server 3 for collecting the bicycle use history information will be described with reference to the flowchart of FIG.

  First, the bicycle use history information collection server 3 is a probe when the user of the mobile terminal device 7 having the device ID stored in the subscriber information DB 331 is near his / her home within a past predetermined period (eg, one year). Information is acquired from the probe information collection server 2 (step S21). Here, the vicinity of the home is a range that can be moved by bicycle (eg, within a radius of 10 km).

  Next, the bicycle use history information collection server 3 determines whether or not the acquired probe information is for when the bicycle is moving (step S22). Here, the determination as to whether or not the bicycle has been moved can be made based on whether or not the movement speed calculated from the displacement of the position information and the time difference is the normal movement speed of the bicycle, for example. In addition to the moving speed, the accuracy can be improved by using the determination result of whether or not the position information indicates that the vehicle is moving on a road through which an automobile cannot pass.

  When it is determined that the acquired probe information is the one when the bicycle is moving (step S22: YES), the CPU of the control unit sets the bicycle flag in the RAM to “1”. On the other hand, if it is determined that it is not the one when the bicycle was moved (step S22: NO), the processing is terminated as it is.

  Next, the bicycle use history information collection server 3 acquires weather information on the positioning date and time of the probe information with the bicycle flag set to “1” from the weather information providing server 5 (step S24), and determines whether or not it was raining. Determination is made (step S25).

  As a result of the determination, if it is raining (step S25: YES), the CPU of the control unit sets the rain flag in the RAM to “1”. On the other hand, if it is determined that it is not rain (step S25: NO), the process is terminated as it is.

  Here, when both the bicycle flag and the rain flag are set to “1”, the user of the mobile terminal device 7 is moving by bicycle and the weather is raining at the positioning date and time of the probe information. Means. If the bicycle flag is set to “1” but the rain flag is not set to “1”, the user of the mobile terminal device 7 is moving by bicycle at the positioning date / time of the probe information. The weather means it wasn't raining. Therefore, by executing this flow, the information shown in FIG. 4 can be stored in the bicycle use history information DB 332.

  Here, step S24 is executed for each probe information in which the bicycle flag is set to “1”, but in actuality, for all probe information in which the bicycle flag is set to “1” for each terminal device ID. Run in bulk. Further, the entire flow of FIG. 7 is also collectively executed for a plurality of portable terminal devices 7.

<Route guidance operation>
Next, an operation in which the route guidance server 4 performs route guidance in response to a request from the mobile terminal device 7 will be described with reference to FIGS. Here, FIG. 8 shows an outline of the entire operation, and FIG. 9 shows details of the route information creation processing in FIG.

  First, the mobile terminal device 7 transmits a connection request to the route guidance server 4 in accordance with a user operation (step S31). This connection request includes the device ID stored in the ROM 712 of the mobile terminal device 7.

  When receiving the connection request, the route guidance server 4 transmits a route guidance condition input screen to the mobile terminal device 7 (step S41). The mobile terminal device 7 receives the route guidance condition input screen and displays it on the display unit 73 (step S32).

  In the mobile terminal device 7, the user inputs, as conditions on the route guidance condition input screen from the operation unit 72, for walking or bicycle, current location (start location), destination location (goal location), desired date and time, etc. By performing the operation, a route guidance request including the route guidance conditions is transmitted to the route guidance server 4 (step S33). Here, when the user does not input the current location, the measurement position by the position measurement unit 74 is set. Further, when the user does not input the desired date and time, the current time that is being measured by a clock (not shown) is set. Such setting information is held by the RAM 713.

  The route guidance server 4 receives the route guidance request (step S42), and creates route information according to the route guidance conditions (step S43). Then, the created route information is transmitted to the mobile terminal device 7 (step S44). The mobile terminal device 7 receives the route information and displays it on the display unit 73 (step S34).

  Details of step S43 will be described with reference to FIG. First, the bicycle use history information on the same day of the week as the date and time (current or desired date) set in the route guidance conditions is acquired from the bicycle use history information collection server 3 (step S51). That is, if the current or desired date and time is Monday, the bicycle use history information for Monday is acquired.

  Next, it is determined whether or not the bicycle flag of the acquired bicycle use history information is “1” (step S52). If the result of determination is not “1”, the bicycle was not used on the day of the week set in the route guidance conditions, so that pedestrian route information is generated (step S58), and the process is terminated. . Here, the determination in step S52 is performed by statistically processing (for example, majority decision) the bicycle flags of all applicable days of the past predetermined period. You may weight according to the time of the day and the season.

  If the bicycle flag is “1” (step S52: YES), it is checked whether the weather information providing server 5 has weather information for the date and time set in the route guidance conditions (step S53). Normally, weather forecasts are made up to one week ahead, so if the set date and time is within the current period or within a predetermined period (one week), there is weather information, and if it exceeds one week, it can be said that there is no weather information. .

  If there is weather information (step S53: YES), the weather information is acquired (step S54), and it is determined whether the weather is rainy (step S55). If the result of determination is that it is not rain (step S55: NO), route information for bicycles is generated (step S57), and the process is terminated.

  If it is raining as a result of the determination (step S55: YES), it is determined whether or not the rain flag of the bicycle use history information acquired in step S51 is “1” (step S56). If it is raining as a result of the determination (step S56: YES), the bicycle is moved on a rainy day on the same day of the week as the set date and time, so that the route information for the bicycle is generated (step S57). The process ends. If it was not rain (step S56: NO), the day when the bicycle was moved on the same day of the week as the set date and time was not rain, so pedestrian route information was generated (step S58), and the process was terminated. To do.

  If there is no weather information (step S53: NO), route information by bicycle is generated (step S57), and the process ends.

  In addition, it replaces with the rain flag which shows whether it is raining, the parameter which shows the grade of rain in steps (example.1-5) is employ | adopted, and it is comprised so that route information may be produced | generated according to the value of a parameter May be. Moreover, although the above embodiment is related with the system which provides route information with respect to a portable terminal device, apparatus ID of the portable terminal device 7 and apparatus ID of fixed terminal devices (desktop personal computer etc.) are obtained. By registering in the associated route guidance server 4, route information can also be provided to the fixed terminal device.
