标准摘要
[中文适用范围]： 本文件规定了“交通事件契约”(TEC) TPEG 应用。 TEC 应用程序专门设计用于支持有关交通事件（例如道路施工、交通拥堵）的信息。 交通事件的一种具体形式是局部危险警告，其是与安全相关的消息，以高优先级发送以警告驾驶员意外的危险情况（例如黑冰、弯道外事故、道路上的障碍物等）。 一般来说，TEC 应用程序的设计目的是让接收器能够： ——确保驾驶员的出行安全； ——能够计算替代路线； ——避免延误（例如交通拥堵）； ——警告驾驶员路线上有障碍物； ——向驾驶员提供有关基础设施问题的信息（例如关闭的加油站、无法使用的紧急电话）。 [外文原描述]： This document specifies the "traffic event compact" (TEC) TPEG application. The TEC application has been specifically designed to support information about traffic events (e.g. road works, traffic jams). A specific form of traffic event is local hazard warnings which, being safety-related messages, are sent with high priority to warn a driver of unexpected dangerous situations (e.g. black-ice, accident beyond curves, obstacles on road, etc.). Generally, the TEC 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).
