If it is determined that it has been received, the process proceeds to step S24. On the other hand, if it is determined that it has not been received (for example, if the first random number has not been received since the first random number has been transmitted), the process returns to step S22.

  In step S24, the processing unit 21 combines the first random number generated in step S22 and the second random number received in step S23 based on a predetermined rule, and generates a system ID.

  In step S54, the processing unit 11 controls the position detection unit 14 to detect the position of the mobile phone 1 at the first time (the position of the first measurement point). The position detection process here and the position detection process in step S57 described later are the same as those described with reference to the flowchart of FIG.

  In step S <b> 55, the processing unit 11 transmits the point information (position information and first time) regarding the first measurement point and the system ID to the management device 2 via the communication unit 15 and the antenna 16.

  Next, in step S56, the processing unit 11 refers to the built-in clock, waits until the current time reaches the second time, and proceeds to step S57 when the second time is reached.

  In step S57, the processing unit 11 controls the position detection unit 14 to detect the position of the mobile phone 1 at the second time (the position of the second measurement point), and in step S58, the second measurement point. The point information and the system ID related to are transmitted to the management device 2 via the communication unit 15 and the antenna 16.

  Thereafter, the process ends. The operation of the management device 2 when receiving the system ID and the point information of the first measurement point or the second measurement point (steps S55 and S58 in FIG. 10) transmitted from the mobile phone 1 is as follows. Since it is the same as that described with reference to the flowchart of FIG.

  Next, details of the process (system ID acquisition process) in step S52 of FIG. 10 will be described with reference to the flowchart of FIG.

  In step S61 to step S64 and step S67, the same processing as in the case of step S11 to step S14 and step S17 in FIG.

  In step S65, the processing unit 11 of the mobile phone 1 uses the communication unit 15 to receive the system ID (the ID generated by combining the first random number and the second random number) from the management device 2, and the first It is determined whether or not the time information of the second time and the second time have been received. If it is determined that the time information has been received, the process proceeds to step S66 to store them in the storage unit 13.

  Next, the operation of the management apparatus 2 when executing a process (system ID assigning process) corresponding to the system ID acquisition process shown in the flowchart of FIG. 11 will be described with reference to the flowchart of FIG.

  Next, the operation of the management apparatus 2 in the case of executing the process of calculating the moving speed (vehicle speed) of the mobile phone 1 using the point information of the first measurement point and the second measurement point will be described with reference to FIG. This will be described with reference to the flowchart of FIG. The first measurement point and the second measurement point here are specified by the management device 2 (FIG. 6).

  In step S81, the processing unit 21 of the management apparatus 2 initializes a value 1 to a counter i that counts the management number i.

  In step S82, the processing unit 21 reads out the position information and arrival time of the first measurement point given the management number of the value of the counter i from the storage unit 23, and was given the same management number in step S83. The position information and arrival time of the second measurement point are read out.

  Next, in step S84, the processing unit 21 calculates the vehicle speed based on the read position information and arrival time of the first measurement point, and position information and arrival time of the second measurement point.

・・・・（１） For example, Formula (1) is calculated and the vehicle speed is calculated. In the formula, coordinates (x1, y1) are position information of the first measurement point, and coordinates (x2, y2) are position information of the second measurement point. T1 is the arrival time at the first measurement point, and t2 is the arrival time at the second measurement point.

(1)

  Next, in step S85, the processing unit 21 determines whether or not the value of the counter i is greater than the maximum number N of the management numbers given to the system ID and the spot information stored in the storage unit 23. If it is determined that the value is not larger, the process proceeds to step S86, the value of the counter i is incremented by 1, and the process returns to step S82. That is, the processes in steps S82 to S86 are repeatedly executed until the respective vehicle speeds are calculated based on all the spot information stored in the storage unit 23.

  If it is determined in step S85 that the value of the counter i is greater than N, the process proceeds to step S87, and the processing unit 21 corresponds to all the vehicle speeds calculated in step S84 with the system ID as shown in FIG. To be stored in the storage unit 23. Thereafter, the process ends.

  Even when the point information of the first measurement point and the second measurement point is determined based on time, the moving speed of the mobile phone 1 is calculated by the same process as the process shown in the flowchart of FIG. In this case, the position information and the first time of the first measurement point are read out in the process corresponding to step S82, and the position information and the second time of the second measurement point are read out in the process corresponding to step S83. The time is read out.

  In the above, the vehicle speed is calculated. For example, the value of the denominator of Equation (1), that is, the transit time between the first measurement point and the second measurement point, is an index that represents the traffic situation. It can also be.

  Next, operation | movement of the management apparatus 2 in the case of calculating space velocity using the vehicle speed calculated as mentioned above is demonstrated.

  The space speed is an average value of vehicle speeds of a plurality of automobiles passing through a predetermined section of the road, and is used as an index representing a traffic situation in the section.

  For example, in the example of FIG. 15, the average value of the vehicle speeds of each of the m automobiles 1 to m traveling in the section indicated by the measurement point A and the measurement point B is set as the space speed of the section.

  The processing procedure of the management apparatus 2 when calculating the space velocity will be described with reference to the flowcharts of FIGS. 16 and 17 (two processing procedures will be described).

  First, the processing procedure shown in the flowchart of FIG. 16 will be described.

  In step S91, for example, the processing unit 21 of the management device 2 calculates the space velocity (corresponding to the measurement point A in the example of FIG. 15) in response to the operation of the input unit 22 of the management device 2 by the administrator. The section to the measurement point B) is determined.

  Next, in step S92, the processing unit 21 refers to the storage unit 23 and is stored corresponding to the position information of the first measurement point and the second measurement point in the section determined in step S91. The current vehicle speed is detected from the storage unit 23. That is, the vehicle speed calculated when traveling in the section is detected.

  In step S93, the processing unit 21 calculates the average value of the vehicle speeds detected in step S92 as the space speed.

  Thereafter, the process ends.

  Next, the processing procedure shown in the flowchart of FIG. 17 will be described.

  In step S101, the processing unit 21 of the management device 2 calculates the space velocity corresponding to the operation of the input unit 22 of the management device 2 by the administrator, for example, as in step S91 of FIG. To decide.

  Next, in step S102, for example, the processing unit 21 corresponds to an operation of the input unit 22 of the management apparatus 2 by the administrator, for example, a time zone for calculating the space velocity (for example, from 10 am to 11 am). Time zone), and further, in step S103, the traveling direction of the vehicle (for example, the upward direction or the downward direction) is determined.

  In step S104, the processing unit 21 refers to the storage unit 23 and is in the time zone determined in step S102, the positional information of the first measurement point and the second measurement point in the section determined in step S101. The vehicle speed stored in correspondence with the time (arrival time, or the first time or the second time) and corresponding to the traveling direction determined in step S103 is detected from the storage unit 23. That is, the vehicle speed calculated when traveling in the determined section, time zone, and direction is detected.

  In step S105, the processing unit 21 calculates the average value of the vehicle speeds detected in step S104 as the space speed.

  Thereafter, the process ends.

  Thus, by determining the time zone in addition to the travel zone and calculating the space velocity, it is possible to know the change in the space velocity for each time zone in the zone. Further, by limiting the traveling direction, it is possible to distinguish between vehicles traveling in the up lane or the down lane.

  In the above, the operation of the mobile phone 1 and the management device 2 when the general information collection button A of the mobile phone 1 is operated has been described. Next, the start / end point information collection button B of the mobile phone 1 is operated. The operation of the mobile phone 1 and the management device 2 will be described.

  First, the operation of the mobile phone 1 will be described with reference to the flowchart of FIG.

  In step S111, for example, an operation to turn on the start / end point information collection button B of the mobile phone 1 is performed, and a signal corresponding to the operation is input from the input unit 12 to the processing unit 11. Proceed to S112. For example, the user (driver) of the mobile phone 1 turns on the start / end point information collection button B at the departure point (for example, in front of the house).
