Wide Area Information Disseminator System --> Other ITS Objects:
wide area broadcast ITS information

Definitions

wide area broadcast ITS information (Information Flow): ITS information of broad interest that is relevant over a wide area and suitable for broadcast distribution. This flow is a super-flow; it does not define specific content since it represents all wide-area broadcast information flows defined in ARC-IT. This information flow represents any of those broadcast information flows and inherits the data content and attributes defined in the more detailed information flows.

Wide Area Information Disseminator System (Source Physical Object): The 'Wide Area Information Disseminator System' represents the center based systems and communications equipment that is used to send messages to equipped vehicles using wide-area wireless communications such as satellite radio, terrestrial FM broadcast subcarrier, or cellular data networks.

Other ITS Objects (Destination Physical Object): Representing other ITS Objects, 'Other ITS Objects' provides a source and destination for information exchange between ITS Objects.

Rating Not Applicable Moderate Low
Basis By definition this is publicly broadcast data. The distribution of this data is intended to be very large, as such the impact of corrupted data will be significant. Probably not HIGH, as there are other distribution channels for this data. There are multiple channels for the delivery of this information, so if this one is not available, others will work. Could consider raising this to MODERATE if it is the sole mechanism able to reach certain areas.
