• Description:
  The primary objective of this project was to develop an integrated freeway control system that can effectively guide the timely activation of key operation components either concurrently or sequentially in contending with daily recurrent congestion. This project produced four traffic models for highway agencies to overcome various constraints existing in practice. Depending on the congestion patterns and their spatial evolution over the target freeway segment, responsible traffic control centers can apply these models individually or collectively, ranging from local ramp metering to coordinated freeway control or eventual integrated corridor management. Such applications can be in either a time-of-day mode or real time responsive mode if traffic detection is available at the required level of accuracy.
