Vehicular wireless short-range communication for improving intersection safety

Vehicle-to-infrastructure and vehicle-to-vehicle communication has recently garnered considerable attention from both academia and industry because it holds the potential to improve road safety and to reduce road accidents. For this reason, V2X communication has been considered a key technology of the future Intelligent Transportation Systems. Use cases for V2X communication for enhancing intersection safety are appealing because intersections are the most complex and dangerous driving environments. This article reviews major related work and presents a communication architecture for intersection safety that supports these use cases. Our communication architecture respects the salient traits of V2X communication and fits into the overall V2X communication architecture. We perform various simulations to quantify the load of V2X communication at intersections and report the findings of our simulation study.
