V2V for Safe Intersections

Increasing the use of information technology (IT) in future vehicles can solve or mitigate many of the fundamental problems that are faced today in transportation such as energy efficiency, reduced carbon footprint for cars, greener environment, and several others. Specifically, the focus of the proposed work is on making vehicles more intelligent for increasing safety at intersections, mitigating congestion, reducing the commute time of urban workers, increasing productivity of the USA (as well as other countries), increasing the energy efficiency of cars, reducing the carbon footprint of cars, and supporting a greener environment. In particular, the project propose a new technology which migrate infrastructure-based traffic lights to in-car traffic. Using the emerging vehicle-to-vehicle (V2V) communications capability of modern cars through the dedicated short range communications (DSRC) standard at 5.9 GHz, it has been shown that this technology can make traffic control ubiquitous at every intersection in urban areas. Through V2V communications, the vehicles at different legs (or approaches) of an intersection can elect a leader which can manage the traffic flow at that intersection, thus acting as a "Virtual Traffic Light". The results of our investigation in the last three years have shown that this technology can reduce the commute time of urban workers between 40-60% during rush hours which seems pretty significant in terms of reducing accidents at intersections, mitigating congestion, increasing productivity, reducing carbon footprint of cars, increasing the energy-efficiency of transportation, and supporting a greener environment.
