This research was directed at designing, developing and implementing a device to monitor vehicle speed and actuate a warning device when critical conditions of low speed and volume were attained. An initial device was developed and field tested by the Transportation Laboratory. A modified standard product was obtained from a manufacturer and field tested. Both versions of the Traffic Congestion Monitor operated successfully.
