T/ITS 0040-2015 Cooperative Intelligent Transport System Speed Guidance Service Data Specification
Basic Information
Scope
Scope: This standard applies to the application of cooperative intelligent transportation systems that dynamically guide vehicle speeds based on the real-time status of traffic lights, enabling vehicles to pass through intersections without stopping. Main technical content: This standard specifies the terms and definitions between the roadside units in cooperative intelligent transportation systems and various roadside systems such as traffic signal control systems, vehicle detection systems, and violation capture systems in road traffic intersections; data communication protocols; interaction modes; data exchange standards; and standards for roadside units to provide speed guidance data services to vehicle-mounted units, among other content.
