Analysis of speed using Radar, Vascar, Lasers and other techniques
In 1983 I acted as an adviser to the Scientific Research and Development Branch of the Home Office in connection with its extensive technical appraisal of speed measuring devices. After an exhaustive programme of theoretical and practical study, this appraisal culminated in a type approval specification together with recommendations for maintenance, operator training and usage. All speed meters have to satisfy the type approval specification.
I have dealt with several hundred speeding cases where the defendant has claimed some technical problem with the speed measurement.
