Overview

This standard, IEEE 1455-1999 Message Sets for Vehicle/Roadside Communications, is applicable to dedicated short-range communications (DSRC). Within the overall context of DSRC operations, this standard specifies the message set, data dictionary and communications protocols above the open systems interconnection (OSI) data link layer for the DSRC wireless interface. These communications protocols define the low-level commands used to control transponder resources and thereby enable message transfer. This standard also specifies the resources that may be present on a vehicle’s transponder and the means by which the roadside equipment can control those on-board equipment resources.

What are these standards for?

This standard, IEEE 1455-1999 Message Sets for Vehicle/Roadside Communications, in conjunction with related standards governing the data link (ASTM PS105-99) and physical (ASTM E2158-01) layers of the DSRC protocol stack, provides the basis for interoperable, non-interfering DSRC implementations using equipment from multiple vendors. These implementations include commercial vehicle, toll collection, and border crossing applications.

Who uses them?

This standard, IEEE 1455-1999 Message Sets for Vehicle/Roadside Communications, is intended for equipment manufacturers, system integrators, toll and turnpike agency engineers and procurement specialists, research consultants and other interested individuals and groups.

How are they used?

This standard, IEEE 1455-1999 Message Sets for Vehicle/Roadside Communications, may be used in several ways by various DSRC equipment stakeholders, including manufacturers that develop compliant transponders. In addition, it can be used by roadside equipment manufacturers to develop equipment that communicates with such transponders. Transponder and beacon manufacturers should note the internal resources that must be provided within, and commands that are recognized by, compliant transponders. Manufacturers of roadside equipment utilize protocols found in this standard to complete the communications stack between the data link layer and application-level processing. Finally, ITS application developers (such as engineers for toll or turnpike agencies) who design and implement systems that use DSRC can utilize the messages that transfer information between related applications.

Scope

This standard, IEEE 1455-1999 Message Sets for Vehicle/Roadside Communications, specifies:

  • Overall DSRC architecture;
  • Scope and organization of the resources provided on compliant transponders;
  • Commands that are used to control transponders and memory areas used to store information;
  • Roadside resource manager that arbitrates requests for transponder usage;
  • ITS application-specific messages that may be stored in the transponder memory areas; and
  • Services that are used to connect the upper layer processing with the DSRC data link layer.

This standard also indicates the manner in which new systems achieve backward compatibility or noninterference with existing systems.
