Development of verification device for on-site velocity measurement error of vehicle speed monitoring system

In order to accurately detect the velocity error of motor vehicle speed monitoring system, a high accuracy velocity measurement device was set up next to the vehicle speed monitoring system. The device is able to carry out synchronous measurement and synchronous image acquisition on the social vehicles in the area of equal speed monitoring and image acquisition. Based on a target velocity source of social vehicles, the vehicle speed monitoring system was verified and calibrated by comparing the two velocity values between the target vehicle and measured vehicle. In order to verify the linearity and error of the measured velocity values of the monitoring system, the proposed verification device is able to measure as many samples of social vehicles as possible and comparatively analyze the measured velocity values around the limited value. The device is easy to install and convenient to use. It can significantly improve the efficiency of verification and operational safety.
