Intelligent transport systems. Traffic and travel information (TTI) via transport protocol experts group, generation 2 (TPEG2). Traffic event compact (TPEG2-TEC) | Status: Superseded, Withdrawn

1 Scope This part of ISO/TS 21219 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, non-functioning emergency telephones).
