Abstract

The use of lasers, cameras, and advanced signal processing to help isolate individual offenders on crowded highways is discussed. The limitations of the predominant radar in use today, namely down-the-road Doppler-radar in which the axis of the antenna is directed along the line of travel of the target vehicle, are described. The potential of video records, across-the-road radar, and both across and down-the-road laser systems is examined. Passive monitoring and the use of surveillance cameras at red lights are also considered
