Component

This research effort is geared towards better representation of vehicle dynamics in traffic simulation. The result will not only lead to improved understanding of traffic dynamics but also provide insight into highway design, traffic safety, more accurate estimates of vehicle emissions, and transportation forensics. The objective of this paper is to propose a simple and computationally affordable dynamic vehicle model that is capable of representing vehicle movement with high fidelity. The objective is accomplished by mathematical representations of a vehicle’s power-train, brake and steering mechanisms while providing a medium through which a driver can interact with these components. The effects of some of the more dominant external forces on vehicle motion as also accounted for in the vehicle model. Validation results demonstrate that this model is successful in representing acceleration, braking and steering performance of three passenger cars.
