Annex Operational radiocommunication objectives and requirements for advanced ITS 1 Elements of ITS Based on major services required for ITS, the elements of ITS and the associated RF interfaces are listed in the following sections. For rural area applications, it may be necessary to appropriately tailor these technologies to meet the operational requirements. 1.1 Advanced vehicle control systems Advanced vehicle control systems are oriented to complementing major portions of the driving task. Radio interface options Elements helps to prevent head-on, radar, high-resolution shortrange Longitudinal collision avoidance: or backing collision between vehicles, vehicles to objects or radar, millimetre-wave communications pedestrians helps prevent collisions when vehicles Short-range radar, high-resolution shortrange Lateral collision avoidance: leave their lane of travel radar prevent collisions at Short-range vehicle-to-vehicle, Intersection collision avoidance: intersections toinfrastructure communication, communications, shortrange radar improves driver’s ability to see the Forward looking infrared radar, Vision enhancement systems: roadway and objects on or along the roadway resolution short-range radar (short-range radar) anticipates an imminent collision Short-range radar, high-resolution shortrange Pre-crash restraint deployment: and activates passenger safety systems before the collision occurs radar earlier than is currently feasible Short-range vehicle-to-vehicle Automated road systems communication, short-range radar, short-range vehicletoinfrastructure communication provides warnings about the condition of the Shortrange vehicle-toinfrastructure Safety readiness: driver, the vehicle and the roadway communication, wide area communication 1.2 Advanced traffic management systems Advanced traffic management systems are intended to improve traffic flow and result in more efficient use of the road systems. Elements Radio interface options manages the movement of Radar, short-range vehicletoinfrastructure Traffic network monitoring and control: traffic on streets and highways communication, broadcast, wide area communications supports policies and regulations Short-range vehicle-to-infrastructure Travel demand management: designed to mitigate the environmental and social impacts of traffic communication, broadcast, wide area congestion communication
