Abstract
A Traffic-Light Status Remote Sensor System is disclosed. The basic system consists of a set of lenses, detectors, and narrowband filters. The sensor system is capable of determining the status of a traffic light (red, amber, or green) from a distance, without any connection to the electronic boards controlling the traffic light. A portable red-light photo-enforcement system working independently from the traffic light controllers is a potential application of the remote traffic light sensor.
