Recent development of inter-vehicular wireless communication technologies have motivated many innovative applications aiming at significantly increasing traffic throughput and improving highway safety. Powerful traffic simulation is an indispensable tool for developing these applications and studying their effects before large-scale deployment. One of the necessary advances to such a tool is to incorporate vehicle dynamics in traffic simulation so that the effects of improved driving strategies and the cooperation between drivers can be examined at a great level of detail. Existing dynamic vehicle models, typically developed for single vehicle applications (such as vehicle design) with high modeling fidelity, are not suited for efficient simulation of many vehicles in a traffic system. To fill the gap, we propose a simple Dynamic Interactive Vehicle (DIV) model which requires little calibration effort and computational resources. The DIV model takes as input a driver’s desired level of acceleration, deceleration, and steering, and outputs vehicle dynamic responses including longitudinal and lateral accelerations, and yaw velocity.
