Abstract:Vehicle-to-infrastructure (V2I) communication, which involves the exchange of safety and operational data between vehicles and elements of the transportation infrastructure, offers a wide range of safety, mobility and environmental benefits. When cars, buses, trucks and emergency vehicles are able to “talk” to traffic signals, stop signs, crosswalks and other features of the surface transportation system, drivers can be alerted and avoid crashes. Traffic management centers can use the data to improve system performance and minimize environmental impacts. Even bicyclists and pedestrians carrying smartphones can participate in the V2I communication network, enabling traffic control devices to respond to their behavior. The V2I program seeks to identify, develop and deploy applications that leverage the full potential of V2I communication to better inform travelers, enhance operational practices and transform surface transportation systems management. V2I technology is a key focus of the connected vehicle research of the Intelligent Transportation Systems Joint Program Office (ITS JPO) within the U.S. Department of Transportation (USDOT) Office of the Assistant Secretary for Research and Technology (OST-R). Today, the program aims to apply the results of that research to facilitate V2I deployments that provide real-world benefits. ITS JPO coordinates its V2I-related efforts with agencies within USDOT including the National Highway Traffic Safety Administration (NHTSA), Federal Motor Carrier Safety Administration (FMCSA), Federal Highway Administration (FHWA), Federal Transit Administration (FTA) and Federal Railroad Administration (FRA).
