DSRC

Introduction

Dedicated Short-Range Communications (DSRC) provide communications between a vehicle and the roadside in specific locations, for example toll plazas. They may then be used to support specific Intelligent Transport System applications such as Electronic Fee Collection.

DSRC are for data-only systems and operate on radio frequencies in the 5,725 MHz to 5,875 MHz Industrial, Scientific and Medical (ISM) band. DSRC systems consist of Road Side Units (RSUs) and the On Board Units (OBUs) with transceivers and transponders. The DSRC standards specify the operational frequencies and system bandwidths, but also allow for optional frequencies which are covered (within Europe) by national regulations.

DSRC systems are used in the majority of European Union countries, but these systems are currently not totally compatible. Therefore, standardization is essential in order to ensure pan-European interoperability, particularly for applications such as electronic fee collection, for which the European imposes a need for interoperability of systems.

Standardization will also assist with the provision and promotion of additional services using DSRC, and help ensure compatibility and interoperability within a multi-vendor environment.

CEN TC 278 produced the following standards: EN 12253, EN 12795, EN 12834 [ISO 15628] and EN 13372 for DSRC.

Our Role & Activities

The base standards for DSRC have been developed by CEN. ETSI's work on DSRC complements the CEN activity in response to a European Commission Mandate (M/338 - issued to ETSI, CEN and CENELEC) in support of Interoperability of electronic road toll systems.

With the assistance of a Special Task Force (STF 282) to produce interoperability test suites, ETSI is producing two multipart standards for DSRC:

  • European Standard EN 300 674 - Road Transport and Traffic Telematics (RTTT); DSRC transmission equipment (500 kbit/s / 250 kbit/s) operating in the 5.8 GHz Industrial Scientific and Medical (ISM) band. Part 2 of this European Standard is the Harmonised Standard that may be used to demonstrate compliance of roadside equipment and on-board units to the European Commission's Radio Equipment Directive (RED)
  • ETSI Technical Specification TS 102 486 - Test specifications for DSRC transmission equipment.

  • CEN has developed the DSRC base standards, upon which the ETSI work is based
  • Technical Committee TC 204 of the International Organization for Standardization (ISO) is working on Intelligent Transport Systems, and its TC22 is working on in-car equipment
  • The ICT Standards Board has an Intelligent Transport Systems Steering Group.
