LATE NIGHT TRAFFIC SIGNAL CONTROL STRATEGIES FOR ARTERIAL SYSTEMS

The late night low volume arterial roadway presents a specific signal aontrol problem. The control decision involves a trade off between the motorists on the artery and those on the cross streets. The motorists on the artery are irritated by frequent stops if signals are not coordinated, while those on the cross street are annoyed by a long waiting time if signals are coordinated. The choice between coordination and free operation is often subjective, especially when semi-actuated signals are involved. The paper presents a method to facilitate the choice between coordination and free operation on arterial roadways controlled by semi-actuated signals when traffic is light during off-peak hours. The decision is made based upon a disutility function which is a combination of the number of stops on the artery and the average cross street waiting time. A case study was performed to demonstrate the application of this methodology under the closed loop signal system in the City of Gainesville, Florida. The results indicate that this method provides a promising tool for arterial control with semi-actuated signals during late night hours.
