General European Road Data and Information Exchange Network

Objective

GERDIEN is an architectural project in the DRIVE programme, the project covers technical aspects of the IRTE. The main objective of the GERDIEN project is to develop an open framework for traffic data collection and exchange. This framework will allow for the flexible integration of ATT applications at all levels. It will cover a major part of the infrastructure required for Dynamic Traffic Management in interurban parts of the IRTE. A secondary objective is to implement and evaluate a part of the framework in a real world environment.

Technical approach

The implementation of Dynamic Traffic Management requires an open and consistent infrastructure, in which vehicle equipment, roadside processors, traffic centres and end-user applications cooperate harmoniously. The ideal framework for this infrastructure is a collection of interface standards, that will allow for an open market in the development of modular systems and for optimal sharing of equipment and communication facilities.

In an architectural approach independent functional modules, with resulting minimal logical interfaces, naturally follow from an overall functional analysis. In the following design of the interfaces, communication protocols, common location referencing and data formats must be included.

Various partial solutions for applications and interfaces in the IRTE have resulted from the DRIVE-I programme. Bringing them together in an integrated environment will be a major step forward in the achievement of the IRTE. The Gerdien project is aimed at a foundation for Traffic Control functions in Dynamic Traffic Management. The applications selected for implementation in a pilot environment in the vicinity of Rotterdam, are Network Monitoring & Prediction, Weigh-In-Motion Monitoring and Road Safety Monitoring. Unless extendibility and flexibility are built-in in this first phase towards Integrated Traffic Control, future phases will not be completed without severe modifications to first phase equipment. The evaluation as part of the GERDIEN project will be aimed at architectural aspects of the environment, in terms of reliability, independency and extendibility.

The main topics in the project are:

The use of cabling networks for transparent communication to roadside applications.
Modular roadside systems for a collection of peripherals including meteo sensors, beacons, vehicle detectors, video camera's and weigh-in-motion detectors.
Traffic Monitoring applications based on a common information model for the road-network.

Key Issues

Communication technology for the IRTE, based on OSI/DNT principles
Development of Universal Roadside systems
Development and evaluation of algorithms and presentation tools for Dynamic Traffic Monitoring.
Application of digital roadmaps for dynamic data presentation and exchange
Development of data management systems using structured design methods
Implementation of a real world test site to demonstrate the Gerdien concepts

Expected impact

The impact to the DRIVE programme will be a major contribution to the IRTE architecture and increased understanding of the technical constraints related to the implementation of the IRTE.

The outcome of the project will be a proposal for a protocol architecture, a validated Design for a Universal Roadside Processor and recommendations for the implementation of dynamic applications in the context of the DRIVE standard digital roadmap.

Contribution to standardisation

The project contributes to CEN TC278 WG9 concerning Dedicated Short Range Communications with specifications for appropriate medium access control schemes and algorithms for the Data Link Layer protocol. These specifications result form performance evaluations by simulation and analysis.
