US: SAE Traveler Info - WAVE WSMP

Description

This solution is used within the U.S.. It combines standards associated with US: SAE Traveler Info with those for V–X: WAVE WSMP. The US: SAE Traveler Info standards include upper–layer standards required to implement V2X traveler information flows. The V–X: WAVE WSMP standards include lower–layer standards that support connectionless, near constant, ultra–low latency vehicle–to–any communications within ~300m using the WAVE Short Messaging Protocol (WSMP) over IEEE WAVE in the 5.9GHz spectrum. The broadcast mode is interoperable with M5 FNTP.

It also describes administrative functions necessary to support the core security functions.
SecurityIEEE 1609.2bIEEE Standard for Wireless Access in Vehicular Environments––Security Services for Applications and Management Messages – Amendment 2––PDU Functional Types and Encryption Key ManagementThis standard defines secure message formats and processing for use by Wireless Access in Vehicular Environments (WAVE) devices, including methods to secure WAVE management messages and methods to secure application messages. It also describes administrative functions necessary to support the core security functions.
ITS Application EntitySAE J2735Dedicated Short Range Communications (DSRC) Message Set Dictionary (TM)This standard defines the data and messages for use in DSRC (i.e., V2V, V2I, and V2D) applications. The SAE J2945 series defines additional requirements on how to use these messages.
ITS Application EntitySAE J2945/4Road Safety ApplicationsThis document revises and extends the existing SAE J2735 message elements in order to include additional travel and roadway information from the infrastructure to enhance safety awareness and promote the exchange and transfer of such messages types between vehicles and the infrastructure (V2I).
FacilitiesSAE J2945Dedicated Short Range Communication (DSRC) Systems Engineering Process Guidance for J2945/x Documents and Common Design ConceptsThis standard defines cross–cutting material which applies to the J2945/x series including generic DSRC interface requirements and guidance on Systems Engineering (SE) content.
TransNetIEEE 1609.3IEEE Standard for Wireless Access in Vehicular Environments (WAVE) – Networking ServicesThis standard defines the network and transport layer options for the WAVE environment. The standard defines three options: a bandwidth efficient single–hop solution known as WSMP, UDP/IP, and TCP/IP. It has been harmonized with ISO FNTP and FSAP – a common message format specified in ISO 16460.
AccessIEEE 1609.4IEEE Draft Standard for Wireless Access in Vehicular Environments – Multi–Channel OperationThis standard primarily defines the data link layer of the WAVE communications stack.
AccessIEEE 802.11IEEE Draft Standard for Information technology––Telecommunications and information exchange between systems Local and metropolitan area networks––Specific requirements Part 11: Wireless LAN Medium Access Control (MAC) and Physical Layer (PHY) SpecificatioThis standard defines the physical and data link layers for wireless Ethernet, including WiFi and DSRC.
AccessISO/IEC 8802–2IEEE Standard for Information technology –– Telecommunications and information exchange between systems––Local and metropolitan area networks –– Specific requirements –– Part 2: Logical Link ControlISO/IEC 8802–2 describes the logical link control (LLC) sublayer, which constitutes the top sublayer in the data link layer of the ISO 8802 Local Area Network Protocol (also known as IEEE 802.2).

Readiness: Moderate–Low

Readiness Description

Multiple significant and minor issues.  For existing deployments, the chosen solution is likely deficient in security or management capabilities, and the issues should be reviewed and upgrades developed as needed. Some solutions in this category may also be becoming obsolete from an interoperability perspective and if this is the case, then upgrades should be planned as soon as possible. For new deployments, the solution may be viable for pilots when applied to the triples it supports; such pilot deployments should consider a path to addressing these issues as a part of their design activities. The solution does not provide sufficient interoperability, management, and security to enable proper, full–scale deployment without  additional work.
