Abstract
The movement of a single vehicle can impact significantly the performance of a traffic stream. Consider a slow-moving vehicle at the front of a long line of vehicles traveling behind it, with no-passing opportunities. The performance of this lead vehicle significantly affects the speed and travel time of the following vehicles. Understanding the characteristics, performance, and movement of each vehicle type allows us to model groups of vehicles and to evaluate the performance of the traffic stream. Furthermore, the movement of individual vehicles allows us to develop better highway design and traffic control solutions. For example, understanding the acceleration and deceleration constraints of various vehicle types can help us design more effective passing zones and to allocate appropriate yellow and all-red intervals at signalized intersections.
