TRAFFIC MONITORING AND WARNING SENSOR UNITS

A traffic sensor unit (150, 250, 300, 400, 520, 522, 524, 770) for monitoring and warning is provided. The traffic sensor unit (150, 250, 300, 400, 520, 522, 524, 770) includes a processor, one or more sensors (310, 402) to sense motor vehicles (140, 240, 540, 542, 544, 546, 640, 645) and one or more alert strobes (330). The traffic sensor unit (150, 250, 300, 400, 520, 522, 524, 770) is to monitor sensor data generated by the one or more sensors (310, 402) and process the sensor data to detect a traffic condition (100, 200), determine a traffic state of a plurality of traffic states based at least in part on the sensor data and enable or disable one or more alert strobes (330) based at least in part on the determined traffic state.
