Abstract:

A radar camera of a signalized traffic control system determines rain intensity, compares it to a threshold, then adjusts traffic signal operation. Rain intensity of a level relative to the threshold causes the traffic control system to operate in a rain intensity mode. The rain intensity mode has the system hold a call to a traffic light controller during the time when rain intensity is above the threshold. The traffic control system includes a radar camera, traffic controller, a computer with memory, and program instructions. A manner of operation includes sampling camera radar, counting the number of raindrops and raindrop size within a predetermined range, determining rain intensity using the measured raindrop parameters/characteristics, comparing the determined rain intensity with a rain intensity threshold, and operating the traffic controller accordingly while the rain intensity is above the threshold.
