Abstract:In recent years, the deployment of wireless communication technologies in transportation systems has gained momentum due to their potential to enhance safety, efficiency, and mobility. Vehicle-to-vehicle (V2V), vehicle-to- infrastructure (V2I) and vehicle-to-everything (V2X) communication systems enable real-time data exchange, enabling vehicles to communicate with each other and with the surrounding infrastructure. This communication facilitates the implementation of new advanced traffic management and safety applications or improvements to existing applications. To determine which applications to implement, transportation agencies will need to develop, test, and evaluate numerous potential strategies using analysis, modeling, and simulation (AMS) techniques, prior to selecting the most effective applications for implementation. Conducting such analysis requires accurate modeling and simulation of wireless communications among vehicles and between vehicles and infrastructure. However, there appears to be limited information on how transportation agencies can incorporate wireless communications into their traditional modeling and simulation activities. Through a comprehensive examination of literature, this white paper seeks to advance the understanding of modeling wireless communications in traffic simulators by documenting the current state of practice, and providing insights on limitations, challenges, gaps and research needs. Potential projects to address the research and development needs are also provided.
