Abstract

Traffic monitors based on non-imaging radiation detectors are described. A traffic monitor includes a non-imaging radiation detector that senses spatially patterned radiation emanating from objects moving in a traffic pattern. The detector generates a time varying output signal based on the sensed radiation. Signal processing circuitry is used to analyze the time varying output signal using time domain analysis to provide the traffic information.
