The moving means estimating means 33 estimates whether the moving means of the mobile terminal 22 is walking, bicycle, car or train from the moving speed calculated by the speed calculating means 32. The moving means estimating means 33 estimates, for example, walking if the moving speed is about 4 km / h, bicycle if the speed is about 20 km / h, car if the speed is about 40 to 100 km / h, and train if the maximum speed is about 100 km / h. To do. Since the moving speed of the car and the train overlap, in addition to the hourly speed information, the information from the acceleration sensor of the portable terminal 21 and the position information are further referred to as necessary to estimate the moving means. To do.

  FIG. 3 shows processing in the server 10 of FIG. In step S <b> 1, the server 10 determines whether or not the recommended route information receiving unit 11 has received a distribution request for recommended route information specifying the departure place and the destination from the user. If there is a distribution request in step S1, the process proceeds to step S2, where the moving means / route search unit 12 acquires the weather information corresponding to the area of the route from the weather information center server 23 via the weather information acquisition unit 13. To do. The travel means / route search unit 12 retrieves recommended route information including the recommended travel means and route from the traffic information DB 14 based on the date / time and weather information of the day, and gives the recommended route information presentation unit 16. The recommended route information presentation unit 16 transmits the received recommended route information to the mobile terminal 21 that has transmitted the distribution request (step S3).

  FIG. 4 is a flowchart showing the processing of the traffic information generation unit 15. The traffic information generation unit 15 extracts the position information from the mobile terminals 22 of an unspecified number of users, and determines whether or not the mobile terminal 22 is moving (step S11). If the mobile terminal 22 has moved, the stop position when the mobile terminal 22 has stopped for a certain period of time prior to step S11 is set as the departure point A of the mobile terminal 22 (step S12). In this case, if the moving distance is less than the threshold value, it is considered that the vehicle has stopped. In step S13, the current weather information is acquired from the server 23 of the weather information center. The season, date (day of the week), current time zone, and weather information are recorded in association with the movement.

  The data generation means 34 of the traffic information generation unit 15 monitors whether or not the mobile terminal 22 stays within a certain distance for a certain time after the mobile terminal 22 starts to move. Consider (step S14). Next, the stop position is set as the destination B, and a route from the departure point A to the destination B is acquired (step S15). The speed calculation means 32 measures the travel time from the departure point A to the destination B (step S16), and calculates the travel speed from the travel distance and travel time from the departure point A to the destination B (step S16). S17). The moving means estimating means 33 estimates the moving means from the moving speed (step S18). Thereafter, when the mobile terminal 22 starts to move further, data is acquired in the same manner with the previous stop position as the departure point and the next stop position as the destination.

  The data generation unit 34 stores the estimated moving unit, route, and moving time (moving speed) for each combination of the departure point and the destination (step S19). FIG. 5 exemplifies the traffic information data generated and recorded by the data generation means 34 regarding the movement from the departure place A to the destination B obtained in this way. In the information of each “route” shown in FIG. 5, the travel time recorded on the route is stored correspondingly. The travel time in which a plurality of movement means such as walking and bicycle or walking and train are combined is also recorded.

  FIG. 6 shows how the traffic information data of FIG. 5 is stored for each traffic condition. That is, the data in FIG. 5 is stored in the traffic information DB 14 for each traffic condition such as date, day of the week, time zone, weather information, and the like. Although not shown, seasonal factors such as summer vacation, winter vacation, and GW are further added to the traffic conditions. Each route information in FIG. 5 is stored, for example, in order from the highest moving speed. The moving speed may be averaged when searching for recommended route information from the traffic information DB 14, or may be averaged in advance prior to searching for recommended route information, and the average value may be used. When there is a request for distribution of recommended route information from the mobile terminal 21 of the user, the moving means / route search unit 12 refers to FIG. 6 and searches for the same traffic condition as that when the request was made. With reference to the data in FIG. 5, the route and travel time for each travel unit are referred to, and the travel unit and route having the shortest travel time are searched.

  An acceleration sensor attached to the portable terminal 22 may be used in combination for detecting the movement of the portable terminal 22 or estimating the moving means. In the above embodiment, an example in which the departure point and the destination specified by the user's portable terminal 21 exist in the traffic information DB 14 as they are. However, for example, the departure point and the destination are in the traffic information DB 14. It may be divided and recorded. For example, if there is an intermediate point C between the departure point A and the destination point B, the route may be searched by a combination of the departure point A and the destination point C and the departure point C and the destination point B. Similarly, if there is an intermediate point C between the destination A and the destination B, the data generation unit 34 uses the data of the departure point A and the destination B as the departure point A, the destination C, and the departure point. Data of C and destination B may be stored.

  In the above embodiment, when the user designates a departure place and a destination and requests information distribution of a recommended route, the shortest time is estimated from the date (day of the week) / time zone / weather information on the server side. A moving means and a moving route are searched from past data and distributed as recommended route information. For this reason, the user can obtain both the recommended moving means and the recommended route, for example, recommended route information suitable for a navigation system mounted on a mobile phone.

  As described above, the present invention has the following effects. The first effect is the calendar information (weekday / Saturday / Holiday / Summer vacation / Winter holiday / GW, etc.) of the requested date for the transportation means and travel route estimated to reach the destination from the departure point in the shortest time. It is possible to derive in consideration of traffic conditions such as time zone and weather information.

  The second effect is calendar information (weekdays / Saturdays / Sundays / Holidays / Summer holidays / Winter holidays / GW, etc.) with recommended route information including travel means and travel routes that are estimated to reach the destination in the shortest time from the starting point. Since the data is stored in the server for each traffic condition such as time zone and weather information, the recommended route information that matches the traffic condition in actual travel can be obtained.

  While the present invention has been particularly shown and described with reference to exemplary embodiments, the invention is not limited to these embodiments and variations thereof. It will be apparent to those skilled in the art that various modifications can be made to the present invention without departing from the spirit and scope of the invention as defined in the appended claims.
