Details of the tests were revealed in evidence to the House of Commons Transport select committee by PIPS Technology, which devised the system,
A Home Office spokeswoman declined to comment on the trials.
The SpeedSpike system uses automatic number plate recognition and GPS to capture the positions of cars and then calculate an average speed over a distance.
