European Digital Road Map II

Objective

Establish GDF as the data exchange standard for RTI systems.
Develop tools for generation and validation of GDF data.
Develop methods for integration of static map data and dynamic traffic information at Traffic Control Centres.

Technical Approach

Modern Traffic Management without digital road maps is not possible. Digital maps are needed for collective and for individual traffic management. Geographic information is essential for problem location, route finding and graphic output of traffic information. Basic research on digital maps has been carried out in DRIVE I (V1010, V1021). The result is the proposed draft standard GDF (= Geographic Data File) for acquisition, modelling and exchange of geographic data. GDF is the only specification which exists for above listed purposes. Furthermore in depth knowledge about data collection and validation has been achieved. After the specifications have been elaborated it is now important to provide tools which enable implementation of digital road maps to data bases, to import and export them from and to GIS (Geographic Information Systems) and to make them available for newly developed services for traffic management. Information which can be provided by digital maps shows the real world at a very particular moment (date of survey). In order to make most up-to-date traffic information available, the following steps have to be considered:

regular update of digital maps
information about foreseeable events (e.g. road constructions)
information on unpredictable events (accidents)
integration of all this type of information

The information will typically be integrated at traffic control centres. Here one can distinguish between different types of traffic control centres depending upon their tasks and their organisations (collective, individual traffic management, fleet management, dispatch management). Beside this some information has to be integrated directly in the car (individual route guidance). All these needs have to be studied in accordance with availability of data. Finally functions have to be specified for pilot applications. Beside above mentioned studies the project EDRM II uses the results of DRIVE I project TFEDRM (V1021) for preparation of pilot applications in QUARTET Project STORM, interurban project Inntal Triangle and in CITIES, a project in and around Paris including the SIRIUS project. A major precondition for the success of the pilot is, that data are available in a commonly agreed form. This requires continuation of standardisation activities of DRIVE I, especially adaptations of the GDF-Specifications. o establish an applicable standard and to achieve an optimum acceptance of GDF, these activities are carried out under the roof of CEN in TC 278 "Road Transport and Traffic Telematics". The most important sources for geographic map data and it's update information are mapping and surveying authorities and road data base owners such as road maintenance authorities. For this reason it is absolutely necessary to coordinate mapping activities with these authorities and to continue the collaboration which has been initiated and successfully started in DRIVE I.

Key Issues

Digital Maps
Road Databases
Generation of GDF data
Integration of (static) digital map data and (dynamic) traffic information
Location Referencing
Traffic Control Centres
Standards

Expected Achievements

Pilot implementations of GDF-based Traffic Data Management Systems
Release of enhanced GDF standard
Requirement profiles and product specifications for GDF verification tools

Expected Impact

The project will deliver specifications and recommendations for handling of traffic information, which will be required in manifold form as soon as complex and conclusive Traffic Management Systems come into use. Tools will become available to generate and to merge data from different sources in a standardized way. These will be basic results for the continuation of activities towards pilot applications in the second half of DRIVE II.

Contribution to standardisation:

One of the major objectives of the project is continuation of the GDF standardisation activities, which in the meantime have been incorporated in CEN activities. WG 7 called "Geographic Road Databases" of TC 278 deals with adaptations of the GDF specifications to RTI needs. Furthermore a homogeneous location coding system valid for different applications with their specific types of geo-referenced information will be developed and standardised.
