BS PD ISO/TS 21219-15:2016 Intelligent transport systems. Traffic and travel information (TTI) via transport protocol experts group, generation 2 (TPEG2). Traffic event compact (TPEG2-TEC)
: Brown Technical Book Store
BS PD ISO/TS 21219-15:2016 specifies the TPEG application: Traffic Event Compact (TEC). The TEC application has been specifically designed to support information about traffic events (e.g. road works, traffic jams). A specific form of traffic events are local hazard warnings which, being safety-related messages, are sent with high priority to warn a driver that may encounter dangerous situations (e.g. black-ice, accident beyond curves, obstacles on road, etc.) unexpectedly. Generally, the Traffic Event Compact application is designed to allow receivers to ensure travel safety for the driver, enable the calculation of alternative routes, avoid delays (e.g. traffic jams), warn the driver of obstructions on route, and provide the driver with information on infrastructural problems (e.g. closed petrol stations, nonfunctioning emergency telephones).
