Synchronous Intersection Management to reduce Time Loss
Ref: CISTER-TR-200707       Publication Date: 16 to 18, Sep, 2020

Abstract:
Conventional intersection management that allows multiple vehicles from one road at a time, e.g., Round-Robin (RR), may constitute bottlenecks in urban traffic management. Consequently, new intelligent intersection management (IIM) approaches were proposed to reduce time loss, fuel wastage, and ecological damage. IIM is also suited to take advantage of the new communication capabilities of autonomous vehicles that are emerging, though still co-existing with human-driven vehicles. This paper extends the analysis of a recently proposed synchronous IIM system, the Synchronous Intersection Management Protocol (SIMP), that is compared with the RR scheme in a four-way single-lane intersection as those found in urban residential areas, under maximum vehicle speeds of 30~Km/h and 50~Km/h and various traffic arrival rates. We characterize performance by measuring time loss, i.e., the additional trip delay due to forced slowdown, supported with an analysis of fuel efficiency. The experimental results obtained with the SUMO simulation framework indicate an advantage for SIMP in both metrics, which becomes a more significant methodology for both urban residential as well as main-road conditions and various traffic intensities.
