TRAFFIC FLOW MEASURING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a traffic flow measuring system capable of measuring a traffic flow parameter at extremely high accuracy without using an ultrasonic wave or an image. SOLUTION: The traffic flow measuring system 1 for measuring a traffic flow parameter such as a vehicle traveling speed expressing the traffic flow of plural vehicles 2 on a road R is provided with plural beacons 3 arranged along the lanes of the road R at a prescribed interval and capable of receiving the vehicle ID of each vehicle 2 transmitted from the vehicle 2 itself when the vehicle 2 passes a prescribed position of the lane and a central control center 10 for generating the moving locus data of respective vehicles 2 on the road R on the basis of the ID information of the vehicles 2, which is received from respective beacons 3 and finding out a traffic flow parameter on the basis of the generated moving locus data of respective vehicles 2.
