ISO TS 21219-15

Description / Abstract: 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, nonfunctioning emergency telephones).
