Vehicle to infrastructure (V2I) is a communication framework that connects vehicles to public infrastructure to capture vehicle-generated traffic data, wirelessly sharing information between infrastructure and vehicles in order to improve safety and traffic efficiency. V2I systems are enabled by vehicle sensors, city camera systems and sensors, software applications, and bi-directional wireless communications. V2I sensors can capture infrastructure data and provide travelers with real-time advisories about such things as road conditions, traffic congestion, accidents, construction zones and parking availability. Likewise, traffic management supervision systems can use infrastructure and vehicle data to set variable speed limits and adjust traffic signal phase and timing to increase fuel economy and traffic flow.
