EU: TPEG2 Parking Information - BTP/GeoNetworking/G5

Description:

This solution is used within Australia and the E.U.. It combines standards associated with EU: TPEG2 Parking Information with those for V-X: BTP/GeoNetworking/G5. The EU: TPEG2 Parking Information standards include upper-layer standards required to implement parking information flows. The V-X: BTP/GeoNetworking/G5 standards include lower-layer standards that support broadcast, near constant, low latency vehicle-to-vehicle and vehicle-to-infrastructure communications using the ETSI GeoNetworking Bundle over the 5.9GHz spectrum.

Relevant Regions:

• Australia
• European Union

Solution Issues Severity: 21

Solution Issues:

Default	Severity	Name	Type	Description
True	Low	Protocol features partly not applicable in the given context	Performance / Applicability Gap	A feature of the protocol is not fully applicable in the given context, e.g. GeoNetworking multi-hop forwarding in 5.9 GHz channels.
True	Medium	Overlap of standards	Overlap	Multiple standards have been developed to address this information and it is unclear which standard should be used to address this specific information flow.
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	Security inadequate	Security Gap	The solution does not provide adequate communications security for the information triple, which potentially jeopardizes C-ITS operations.
True	Medium	Uncertainty about trust revocation mechanism	Security Gap	The mechanisms used to prevent bad actors from sending authorized messages is unproven.
True	High	Data/comm profile pairing	Standardization Gap	There are ambiguities as to how to (or if one should) couple the upper-layer standards defined in this solution with the indicated lower-layer standards.
