The project investigates the utility of an automatic in-vehicle warning system that uses acceleration, speed, driver intent, and other data from several vehicles ahead to help drivers anticipate hazardous situations. Unlike headway warning systems, which have focus on the interaction between the driver's vehicle and the vehicle immediately ahead, this system assumes communication between all nearby vehicles in the vicinity and examines how this information could be used to reduce accident rates. Simulation experiments based on traffic data collected on I-40 in New Mexico were designed to examine the relationship between look-ahead communication range, in both distance and number of vehicles, and the number of accidents that would be prevented. Other questions, such as the effect of less-than-total market penetration of the system on system effectiveness, were also addressed.
