Paper Abstract

Traffic speed enforcement is an important issue to guarantee public road security and to reduce the number of traffic accidents. Traffic speed meters are important legal measuring instruments specially used for traffic speed surveillance and enforcement in China and around the world. An online test method based on actual traffic with no need to close the road is introduced in this paper. Firstly, the principle of the online test method based on actual traffic and the requirements for the standard speed-measuring instrument are introduced. Secondly, three main standard speedmeasuring instruments respectively using piezoelectric film sensors, 3D tracking radar and light barrier are given. Finally, two comparison experiments were carried out in the field to evaluate the field speed-measuring performances of the standard speed-measuring instruments used for online tests for verification of traffic speed meters in actual traffic.
