[Abstract] In this paper, the vehicle-to-infrastructure (V2I) communication system is designed; a couple of on-board communication units (OBU) and roadside units (RSU) are developed; and a real-world networked vehicle (NV) platform of both the OBU and RSU is built and tested. We point out that a V2I communication system lays the foundation for NV, and a dedicated short-range communication (DSRC)-based V2I communication system significantly reduces communication delay during information interaction. This system not only ensures communication quality of the vehicular network at high speed and when the network topology changes but also establishes a reliable, stable, and efficient communication service platform for vehicle-to-vehicle (V2V) and V2I.
