Modelling an Emergency Vehicle Early-Warning System Using Real-Time Feedback

Emergency vehicles, while usually equipped with warning sirens and/or beacons, are still often impeded by other traffic and involved in numerous collisions. An effective warning system for alerting other vehicles that an emergency vehicle is approaching is therefore crucial. The paper is investigating the use of wireless communication from emergency vehicles to warn other traffic. However, communication in dynamic wireless networks is not reliable. In this paper, the authors propose a novel emergency vehicle early-warning system that relies on wireless technology to inform other vehicles of the arrival of emergency vehicles, and returns feedback in real-time when communication degrades.
