The Connected Vehicle Safety Pilot Model Deployment is a major test of safety applications that are based on vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) dedicated short range communications (DSRC). Approximately 3000 vehicles in a mid-sized city (Ann Arbor, MI) will be equipped with devices in order to assess safety benefits in a naturalistic environment. To ensure that sufficient data are collected, participants will be chosen so that their vehicles will interact frequently with each other and with the roadside equipment. Since the 3000 vehicles are a small fraction of all vehicles in the city, choosing a deployment strategy requires careful analysis of the network and traffic flows. This research describes the development of a regional traffic microsimulation model that was used to estimate the number and spatial/temporal locations of V2V interactions under various deployment strategies. Steps taken to develop the model included the following: (a) converted the existing network planning model for the Ann Arbor area to a regional microsimulation model, (b) developed a method to identify the numbers, origins, and destinations of trips using equipped vehicles, and (c) developed postprocessing code to track all equipped vehicles from the second-by-second microsimulation vehicle snapshot data and to identify interactions between equipped vehicles. This interaction information was integrated with available Integrated Vehicle-Based Safety Systems (IVBSS) data to estimate the potential number of conflicts among equipped vehicles. The resulting model was used to assess various safety deployment scenarios in a field operational test.
