Abstract

A field experimental standard for traffic speed measurement was set up at No.G92 Expressway of China from Hangzhou to Shanghai for field tests of vehicle speed-measuring devices in actual traffic, and it met the requirements of the recommendation in OIML R 91 about the metrological field tests of pattern approval. This paper firstly introduces the speed measurement principle of the standard equipment and evaluates the uncertainty of speed measurement. Secondly, a field test based on this standard equipment is designed and performed on a radar speed-measuring device to evaluate its actual speed measurement performance in actual traffic. Finally, the uncertainty of measurement of field test error in actual traffic is evaluated.
