A computer-implemented method and system for testing the accuracy of a road safety camera

Abstract

A speed-accuracy verification system for testing the accuracy of a road safety camera implementing a primary speed detection device, comprising: a video camera configured to capture video of a detection site monitored by the road safety camera over a defined time, the video camera being independent of the road safety camera and having a time clock that is synchronised to a known reference time; a speed verification device implementing a time clock that is synchronised to a known reference time, the speed verification device configured to record verification event data for vehicles passing through the detection site during the defined time and which are determined to satisfy predefined incident criteria, verification event data comprising incident time and vehicle speed; a processor implementing a video event correlation module configured to receive the verification event data and captured video and process the same to generate images of each vehicle satisfying the predefined incident criteria and record corresponding verification event data in association with each image; a processor implementing a camera interface module configured to communicate with the road safety camera to obtain incident event data recorded by the road safety camera over the defined time, the incident event data comprising vehicle speed, incident time and corresponding images for vehicles that satisfy the predefined incident criteria; and wherein the incident event data is compared against data recorded in the verification data log to determine whether the road safety camera is accurately recording vehicle speed. 20 25 20 14 01 27 F eb 2 02 5 A B S T R A C T 2 0 2 5 2 0 1 4 0 1 2 7 F e b 2 0 2 5 Figure 2 100 102 / 115 106 212 / 214 104 112 216a 113 216a 210 200 202 / 203 / 206 / 208 114 108 20 25 20 14 01 2 7 Fe b 20 25 2025 2025201401 27 Feb 113 108 216a 114 200 210
