ABSTRACT:
A residual charge traffic sensor for monitoring the number and speed of vehicles traveling in multiple lanes of a roadway includes a housing containing a cavity, a conductive mounting bar adapted to fit within the cavity, at least two sensing elements mounted on the mounting bar which generate a signal when impacted by a vehicle tire, a transmission cable connected with the sensing elements for transmitting the electric signals generated by the sensing elements, and analyzing equipment for evaluating, displaying, and recording the data generated by the sensing elements. Signals are transmitted through every other wire of the transmission cable to minimize cross-talk between the signal carrying wires.
