Generating Traffic Information from Connected Vehicle V2V Basic Safety Messages

The National Highway Traffic Safety Administration (NHTSA) has proposed issuing a regulation requiring all new cars to have an awareness device broadcasting Basic Safety Message (BSM) containing data about the car's position, speed, and acceleration. The proposed project will filter speed and location information from BSMs through a mesoscopic traffic flow model to create a Traffic State Estimator (TSE) providing traffic measurements at high resolution. By combining the developed TSE with simulation, the functional requirements for a system collecting BSMs from hundreds of thousands of vehicles over a large geographic area will be identified and a prototype of the BSM-based traffic performance measures methodologies will be tested.
