Development and simulation-based testing of a 5G-Connected intersection AEB system

Abstract

In Europe, 20% of road crashes occur at intersections. In recent years, evolving communication technologies are making vehicle-to-vehicle and vehicle-to-infrastructure faster and more reliable; with such advancements, these crashes, as well as their economic cost, can be partially reduced. In this work, we concentrate on straight path intersection collisions. Connectivity-based algorithms relying on 5G technology and smart sensors are presented and compared to a commercial radar AEB logic in order to evaluate performances and effectiveness in collision avoidance or mitigation. The aforementioned novel safety systems are tested in a blind intersection and low adherence scenarios. The first proposed algorithm is obtained by incorporating connectivity information into the original control scheme. The second proposed algorithm is a novel control logic fully capable of utilising the adherence estimation provided by smart sensors. Test results show an improvement in terms of safety of the control architecture and high prospects for future developments.
