Synchronous Framework Extended for Complex Intersections

Abstract:
Current trends towards smart mobility aim at mitigating traffic congestion and providing intelligent and sustainable transportation. Intelligent intersection management systems are an integral part of this trend and profoundly impact urban traffic management. To this purpose, we proposed in prior work a specific Intelligent Intersection Management Architecture (IIMA) for single-lane isolated intersections with an associated Synchronous Intersection Management Protocol (SIMP). The IIMA/SIMP framework targeted autonomous and human-driven vehicles and outperformed competitors in several metrics, i.e., intersection throughput, time loss, fuel efficiency, and polluting emissions. This paper extended such a framework to the more complex scenario of multi-lane intersections, particularly for dedicated left-turn lanes and shared lanes. Using SUMO, we compare its performance against several approaches for traditional and intelligent intersection management. Simulation results under varying vehicle arrival rates confirm the advantages of IIMA/SIMP even in complex intersections, improving intersection throughput, reducing average trip time loss and the average number of stops.
