US: SAE Lane-Level Mapping - WAVE WSMP

Description

This solution is used within the U.S.. It combines standards associated with US: SAE Lane–Level Mapping with those for V–X: WAVE WSMP. The US: SAE Lane–Level Mapping standards include upper–layer standards required to implement lane–level and road furniture mapping 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.

SecurityIEEE 1609.2IEEE Standard for Wireless Access in Vehicular Environments – Security Services for Applications and Management MessagesThis 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.

It also describes administrative functions necessary to support the core security functions.
ITS Application EntitySAE J2945/AStandard for Lane–Level and Road Furniture Mapping for Infrastructure–based V2X ApplicationsThe document provides a generalized mapping solution that can be applied to future infrastructure–based application standards using a layering approach, so that each new application standard at most needs to define a new layer of information that is unique to specific V2X application. It provides an ability to describe small, lane–level map descriptions that apply directly to V2X applications such as reduced speed zones (e.g. work zones) and curves (e.g. curve speed warning).
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.
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.

Readiness: Moderate

Readiness Description

Two significant or one significant and several 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. 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.
