1 Scope
This part of ISO/TS 21219 defines the TPEG Weather (WEA) application for reporting weather information for
travellers. It provides general weather-related information to all travellers and
is not limited to a specific mode of transportation.
This application does not provide specific weather-related safety warnings to drivers;
these are provided as Safety Related Messages as part of the TPEG2-TEC application.
The WEA application provides weather-related forecasts and status information over
multiple time periods and for multiple, possibly linked, geographical areas.
NOTE The presentation of the information is dependent of the specific HMI of the receiving device. This part of ISO/TS 21219, therefore, does not define any prerequisites for the HMI of the device.
