This Technical Specification defines the TPEG application Traffic Event Compact (TEC). It has been specifically designed to support information about traffic events, e.g. road works, traffic jams. A specific form of traffic event are local hazard warnings, which as safety-related messages, are sent with high priority to assist a driver in encountering dangerous situations (e.g. black-ice, accident behind curves, obstacles on road) unexpectedly. Generally, TEC focuses on the following requirements: ensuring travel safety for the driver; enabling the calculation of alternative routes; avoiding delays (e.g. traffic jams); warning the driver of obstructions on route; informing the driver of infrastructural problems (e.g. closed petrol stations, non-functioning emergency phones).
