Advantages of Synchronizing Vehicles Intersection Access
Ref: CISTER-TR-230405       Publication Date: 2023

Abstract:
Intersection space is a common resource that must be efficiently shared between vehicles with conflicting trajectories from several road lanes. The main objective of traffic light control (TLC) strategies is to periodically switch intersection access between road lanes by permitting vehicles either sequentially, parallelly, or synchronously. In this work, we compare the performance of five state-of-the-art TLC approaches in a road network of intersections. Among them, three approaches serve vehicles sequentially from one road lane at a time, one approach permits vehicles parallelly from opposite lanes, and the last one synchronizes the vehicles access to the intersection from all non-conflicting road lanes, one vehicle per road lane. SUMO simulation results suggest that the synchronous approach outperforms the sequential and parallel approaches in a multitude of situations in terms of network throughput, travel time loss and associated fuel consumption.
