This standard defines a framework for Edge intelligent terminal (EIT) devices. The EIT framework defines: 1) Use requirements for Cooperative transportation use cases in typical expressway scenarios, e.g. traffic congestion warning, road condition danger alert and emergency vehicle alerts. 2) The design architecture and essential functionality needed to develop edge intelligence for various expressway related scenarios, including but not limited to autonomous driving remote procedure call, local storage of High Definition (HD) map static data, and fusion of map data with EIT-perceived information. 3) The Information interface between EIT and perception equipment, cloud intelligence and vehicle intelligence to enable cloud-edge & Vehicle to Infrastructure (V2I) data interaction, autonomous driving and cooperative transportation.
