Coordination of Freeway Ramp Metering and Arterial Traffic Signals

In the current state of practice, arterial traffic signals and freeway ramp meters operate independent of each other. Arterial traffic control typically maximizes traffic flow by progressively coordinating series of adjacent traffic signals while freeway ramp meters maximize the mainline flow by restricting arterial traffic from entering the freeway if the total demand from the mainline and the arterial exceeds the freeway’s capacity. However, implementing these control strategies with conflicting objectives has resulted in reduced performance of both the freeway and the arterial. The project proposes a control strategy for coordinating arterial traffic signals with freeway ramp metering. Currently, the control strategy is being simulation tested on a freeway corridor with multiple on-ramps and adjacent arterials. Field implementation has been planned for future work. This project is joint work with Xiao-Yun Lu and Prof. Alexander Skabardonis.
