IEEE 1455-1999

Research, compile, and consolidate information leading to the publication of a standard for exchanging DSRC information, providing for bi-directional message transmission and device control, in a manner which is compatible with but independent of the ASTM efforts to specify DSRC Layers 1 and 2. This will entail specifying the transponder resources, the transponder resource manager, the application message sets, and the signals and services such as the Electronic Toll and Traffic Mgmt User's Group, the ATA, the CVO community, the vendor community, and other standards bodies to synthesize existing messaging requirements into a single, open industry standard which supports non-interfering and interoperable DSRC implementations by the various user agencies.

The ETTM field is rapidly emerging with multiple technologies and incompatible products. In addition, the emergence of the ASTM standard for Layers 1 and 2 has created the potential for significant interference between RF compatible systems. The lack of standard message sets, lower layer protocols, and transponder resource definitions threatens to postpone the deployment of this critical technology to the marketplace. The effort behind this PAR will consolidate and publish a standard to support Commercial Vehicle Operation and ETTM. The open nature of the developed interface will ensure that it is extensible to other DSRC areas, e.g. CVO credential information exchange, pre-clearance screening, fleet management and private messaging.

New IEEE Standard - Inactive-Withdrawn. Those characteristics of a dedicated short-range communications (DSRC) system that are independent of the Physical and Data Link Layers (ISO model Layers 1 and 2) are specified.The required and optional features of the roadside equipment (RSE) and the onboard equipment(OBE) are specified. In addition, the Applications Layer (ISO model Layer 7) services and protocols,the RSE resource manager, the corresponding OBE command interpreter, and the application-specific messages are all specified. Standard supports and guidelines are provided for implementing secure DSRC systems.
