は以下のような式で表せる。Next, the relationship and operation of each of the above components will be explained. A vehicle sensor 1 transfers data on vehicles that have passed through that point to a data collection unit 2. The traffic data calculation unit 3 calculates traffic data (traffic volume, speed, occupancy rate, etc.) per unit time. The traffic data processing unit 4 deletes the traffic volume calculated by the traffic data calculation unit 3 that does not reach a certain threshold. The output unit 5 outputs the results obtained by the traffic data processing unit 4. Specifically, the operation of the traffic data processing unit 4 can be expressed by the following equation.
