Modeling the Effects of Speed Limit, Acceleration, and Deceleration on Overall Delay and Traffic Emission at a Signalized Intersection

摘要

This paper proposes a microscopic spatial-temporal method to capture the vehicle movement trajectories at an isolated intersection. A bi-objective programming model is presented to minimize the overall delay and emission increment with and without traffic signal by jointly determining the optimal signal timing and speed limit. The proposed method explicitly incorporates the effects of vehicle speed limit, acceleration, deceleration, and signal timing on the overall delay (including the delays caused by traffic signal, acceleration, and deceleration) and emission increment with and without traffic signal control at the intersection.
