Empirical Study and Modeling of Vehicular Communications at Intersections in the 5 GHz Band
Mobile Information Systems
Event warnings are critical in the context of ITS, being dependent on reliable and low-delay delivery of messages to nearby vehicles. One of the main challenges to address in this context is intersection management. Since buildings will severely hinder signals in the 5 GHz band, it becomes necessary to transmit at the exact moment a vehicle is at the center of an intersection to maximize delivery chances. However, GPS inaccuracy, among other problems, complicates the achievement of this goal.doi:10.1155/2017/2861827 fatcat:oakkykedonfzziyvghz6z5mawa
