Background

There is a high probability of traffic accidents at an intersection in which many of the accidents result in fatalities.  Because of obstructions surrounding the intersection many of these accidents are due to a lack of visual warning.  Critical decision making by drivers is dependent on extra information about the situation.  A vehicle-to-vehicle communication system is the path to providing this information.  Using a precise sensory network, coupled with an effective wireless communication system, we will provide a proof of concept of vehicle-to-vehicle communication.

 

Abstract

When vehicles approach an intersection there is the potential risk of colliding with another vehicle. The cause for these collisions are the result of careless action by the driver and obstructions that prevent the drivers from making any preliminary assessments of a potential accident. A vehicular ad-hoc network provides a means for drivers to assess and react to dangerous situations on the road.
