Intelligent Transport Systems

Introduction

Intelligent Transport Systems (ITS) include telematics and all types of communications in vehicles, between vehicles (e.g. car-to-car), and between vehicles and fixed locations (e.g. car-to-infrastructure). However, ITS are not restricted to Road Transport - they also include the use of information and communication technologies (ICT) for rail, water and air transport, including navigation systems.

In general, the various types of ITS rely on radio services for communication and use specialized technologies.

Automotive systems

Currently, there are currently the following projects related to automotive ITS:

  • Dedicated Short-Range Communications (DSRC) provide communications between the vehicle and the roadside in specific locations (for example toll plazas). Applications such as Electronic Fee Collection (EFC) will operate over DSRC.
  • Wireless Communications Systems dedicated to Intelligent Transport Systems and Road Transport and Traffic Telematics will provide network connectivity to vehicles and interconnect them. Using radio bands requires adequate Harmonised Standards which are under development for the bands 5 GHz and 63 GHz.
  • Continuous Air interface Long and Medium range (CALM) provides continuous communications between a vehicle and the roadside using a variety of communication media, including cellular, 5 GHz, 63 GHz and infra-red links. CALM will provide a range of applications, including vehicle safety and information, as well as entertainment for driver and passengers.

These technological projects form part of wider initiatives on matters such as road safety (for example the European Commission's eSafety initiative) and road tolling.

Railway systems

The railways industries have agreed to use GSM for the signalling on high speed railways, as well as for conventional railways when interoperating across national boarders. Within Europe, interoperability of high-speed railways is a regulatory requirement, addressed by the European Commission's Directive 96/48/EC.

Aeronautical and maritime systems

Aeronautical applications extend from professional services, such as air traffic control systems, to services for passengers, such as onboard telephony, and ETSI is responsible for specifying many of them.

Maritime applications support routine maritime operations, including navigation, as well as safety purposes. ETSI is responsible for producing a range of technical standards and reports concerning radio equipment and system for maritime and inland waterways use.

Our Role & Activities

Our ITS committee (TC ITS) is leading the drive to achieve global standards for Co-operative ITS, which offers enormous potential through vehicle-to-vehicle and vehicle-to-roadside communication. Applications include road safety, traffic control, fleet and freight management and location-based services, providing driver assistance and hazard warnings and supporting emergency services.

Release 1 standards are being fine-tuned, taking account of feedback received. Release 2 is being developed and will include new features and functionalities anticipated in future Co-operative ITS. In particular, it will include specifications to protect vulnerable road users such as cyclists and motor cycle riders, and for Co-operative Adaptive Cruise Control. It will also address platooning, a practice which is expected to save both fuel and space on the roads.

Work is ongoing on the Co-operative Observation Service, whereby sensor information is shared between road users to, in effect, extend a driver’s field of vision, and we have initiated pre-studies into relevant use cases. Cross layer Decentralized Congestion Control for the management of Co-operative ITS is being addressed.

Conformance tests, which are crucial for the commercial deployment of Co-operative ITS are being developed. Our Technical Specification (TS) on mitigation techniques is being revised to avoid interference between European CEN Dedicated Short Range Communication equipment and ITS operating in the 5 GHz frequency range. Spectrum requirements of Release 2 are continuously being addressed.

Our Automotive Radar standards take recent developments into account. In the Ultra Wideband automotive radar area, our Harmonised Standards for ground based vehicular radar in the 76 - 77 GHz range and high resolution automotive radar in the 77 - 81 GHz range are being revised in the light of the EC MOSARIM project on radar interference mitigation and the amended regulatory framework. A new European Standard (EN) on the use of helicopter radar to prevent accidents is being developed.
