EU: In-Vehicle Information - Wide Area Broadcast

Description:

This solution is used within Australia and the E.U.. It combines standards associated with EU: In-Vehicle Information with those for C-X: Wide Area Broadcast. The EU: In-Vehicle Information standards include upper-layer standards required to provide a visualisation of static and/or dynamic traffic sign information inside a vehicle. The C-X: Wide Area Broadcast standards include lower-layer standards that support one entity broadcasting information to all wireless devices over an area that covers at least a metropolitan area without any expectation of acknowledgement or response; security is provided by the upper-layers.

Solution Issues Severity: 7

The severity issue score calculation only includes issues associated with standards that are included by default.

Solution Issues:

Default Severity Name Type Description
True Low Ubiquitous broadcast technology SubNet Gap With the continual enhancement of broadcast technologies and a mixture of free and subscriber-based systems, it is difficult to identify any single technology that can be used to reliably reach the bulk of drivers in a timely manner.
True Medium Secure data access not provided Security Gap The solution does not define rules on how the application entity authenticates requests to accept or provide data.
True Medium Use case not considered in design (medium) ITS Info Gap While the indicated standards nominally address the information flow, the design may not meet practical constraints because this particular use case was not the focus of the design effort.
