Comparison of Delay Time Models for Over-Saturated Traffic Flow Conditions at Signalized Intersections

Abstract

Delays at the signalized intersections the most important parameters of the signal timing optimization and level of service (LOS) estimations. The determination of the delays at the signalized intersections has a significant importance for the evaluation of the performance and travel time of the transportation modes. The optimization of the travel time delays at the signalized intersections provides a better fuel economy. This study compared these delays in the scope of the various model studies in Turkey and other countries considering the signalized intersection approaches controlled in fixed-time and operated in a range of conditions. This study also specifically focused on the differences between Iran and Turkey considering the modal approaches and the driver behavior variations.
