Abstract
The present invention extends to configuring detection zones in a traffic monitoring system and to association of detection zones with corresponding traffic signal phases. One or more sensors detect targets within a roadway intersection. The sensors integrate acquired sensor data for the targets into track files. The track files are subsequently used to identify common target paths. A histogram is used to identify common target positions for stationary targets. From the common target positions and the common target paths detection zones are configured. Detection zones are associated with traffic signal phases so that specific detections can be created. Lane boundaries within the roadway intersection are inferred from the common target paths. Permanent stationary target locations are identified from the common target positions.
