Reactive Cooperation of Multi-Vehicle System for Efficient Intersection Crossing Based on PIDP Speed Space Assessment

This paper proposes a Dynamic Collision-Free Co-operative decision-making method based on the Predicted Inter-Distance Profile (DCFC-PIDP) for Connected Autonomous Vehicles (CAVs), aimed at solving congestion, and increasing the efficiency and safety of the transport system. Under this framework, this paper studies a typical urban driving scenario: unsignalized intersection. The method employs a greedy algorithm to explore with an appropriate metrics, the main possible scenarios, involving CAV s with a risk of collision and find the suboptimal feasible solution. The decision-making cost function is constructed by considering the risk of collisions and the passing efficiency of CAV s. Finally, the effectiveness and feasibility of the proposed decision-making framework are verified under statistic studies.
