Microscopic Estimation of Freeway Vehicle Positions from the Behaviors of Connected Vehicles

Noah Goodall, Brian Smith & B. Brian Park
The modern passenger vehicle is an incredibly sophisticated machine, with computer monitoring and control of most of its functions, including speed, acceleration, heading, and GPS-enabled position. Vehicles are beginning to communicate these data wirelessly to other vehicles and to roadside equipment.
