Volume-based Probabilistic Approaches to Determining When to Turn on and off Signal Coordination Plans
Traffic signal coordination is an engineering tool used to enhance the quality of traffic flow, increase traffic throughput, reduce travel time and delay, and reduce number of stops by providing good progression along major arterials. While vehicles on major arterials benefit from signal …
