Dr. G.L. Chang's Team to Demonstrate New Variable Speed Control System in Maryland

The research team led by Dr. Gang-len Chang is demonstrating a travel-time estimation and variable speed control system on the segment Between MD100 and US29 for mitigating day-o-day recurrent congestion. The entire control system consists of 4-image cameras for license plate recognition, 4-radar sensors for flow measurement, and 4 variable message signs for displaying estimated travel time and the suggested optimal speed. The research team will collect both field data and driver responses during the one-month demonstration period for effectiveness evaluation. This project is sponsored by Maryland State Highway Administration.
