Abstract

A method is disclosed for enforcing a speed limit in a zone of a roadway, such as a construction zone, where the ability of an officer to stop a speeding vehicle may be limited. A Doppler traffic radar unit and a video camera are set up at an off-road surveillance site typically adjacent the zone, and aimed at a common target area in the zone through which vehicles will sequentially pass. The speed information, Doppler audio and video are transmitted from the surveillance site to a more distant off-road location (remote site) that is accessible from the roadway, where a patrol car is located. The patrol car at the remote site receives the transmission and is equipped with an in-car video/audio system having a video buffer and a record mode. When the officer witnesses a speeding target vehicle on the video screen and hears the corresponding Doppler tone, the officer activates the video/audio system to the record mode to provide a video record of the violation including the period prior to activation stored in the history buffer. The officer may then apprehend the violator after the target vehicle leaves the restricted zone.
