The close integration of vehicles and the infrastructure in the surface transportation system has been envisioned for years, but recent advances in wireless communications has made such integration feasible. Given this feasibility, a coalition of the public and private sectors is currently exploring the national deployment of vehicle infrastructure integration (VII), based on the relatively new Dedicated Short Range Communications (DSRC) standard. The Virginia Department of Transportation (VDOT) is a member of this coalition, known as the National VII Coalition. Most of the effort at the national level is focused on technology aspects and study of safety benefits. In order to best inform design, deployment and operations decisions, it is also necessary to fully evaluate potential VII-enabled operations applications. This research effort focused on the development of a simulation environment to model VII and associated operations applications. This model was then used to begin to explore implications of VII design decisions on the potential for VII to support traffic operations. A major contribution of this research was the development of a high resolution VII/traffic simulation environment. This environment uses AIMSUN for traffic simulation, integrated with custom code that emulates VII functionality. Using this model, VII roadside units (RSUs) were 'placed' based on guidance from VII architecture and the extent of VII coverage was determined. A prototype traffic monitoring application was developed and evaluated for various penetration rates of VII equipped vehicles on an urban traffic network in the Tysons Corner area.
