ABSTRACT:
A traffic monitoring system including a non-intrusive lane monitor is provided. The lane monitor comprises one or more laser channels, a user interface, and a programmable controller in communication with the laser channels and the user interface. In accordance with one embodiment of the present invention, a pair of laser channels are provided. The first laser axis is substantially parallel to the second laser axis and the first and second laser axes lie substantially in a common horizontal plane. The programmable controller is configured to generate reflected laser pulse count corresponding to reflection of a pulsed laser signal from a target positioned along one of the laser axes and identify the reflected signal as a valid or invalid target by comparing the pulse count to a predetermined valid target count.
