Driver Information Systems

Objective

The goal of the project is to specify the integration of existing systems into a comprehensive driver information system operating across Europe. The first objective of the project is to define the nature of driver information systems by:
- determining and evaluating users information requirements,
- evaluating alternative technical methods for data handling,
- and by the development of information generation and dissemination procedures.
The research has resulted in a handbook containing recommendations for performance standards of driver information systems.

The object of the Handbook is to:
direct manufacturers to develop and produce driver information system components which can be used all over Europe;
influence information providers to develop databases and value added services that meet the requirements of an integrated European information system;
enable public and private transport organisations to make their information and traffic control systems compatible with driver information systems;
help administrators and authorities implement driver information systems which can be integrated in a European driver information network;
give drivers a guarantee that they will have access to certain types of information wherever they are travelling in Europe.

A list of advanced software tools was specified which, based on various data sources, establish and manage a comprehensive information system. Existing algorithms were described and characterised according to their requirements and potential efficiency. In addition, possible physical units were investigated which may be components of a coherent information system and which can realise any given set of applications at different levels of technological development. General rules and principles for networking, standardisation and information dissemination have also been elaborated.

The research resulted in a proposal for a system architecture to permit substantial volumes of data to be passed between numerous (public and private) actors. That architecture requires the creation of a TDI network involving the interworking of various communications networks based on international standard messages. Two principle components are needed to realised this requirement:
a common network interface attachment facility;
messages incorporating standard location referencing, syntax and rules.

An additional requirement identified, but as yet not resolved, is the need to create appropriate management and financial regimes. Possible management models are suggested, although detailed analysis has not been possible.

The research led to the following results:
hardware units and software tools;
a modular structure was elaborated;
a general framework for a comprehensive information system was obtained;
it was shown how different activities in road transport informatics development are integrated into a cooperative overall system;
synergetic effects were made evident;
feasible structures for information flow were derived.

A European driver information system (DIS) has been developed based on an examination of existing driver information systems in operation inside and outside of Europe. The systems which could be integrated into the European concept and the experience gained from the structure and operation of these systems were taken into account.

The research provided recommendations in the following areas:
driver information requirements;
requirements for data collection and transmission;
data processing and control issues;
information transmission and dissemination mechanisms;
information reception requirements of users.

The characteristics of 79 existing worldwide driver information systems were studied with regard to their relevance to a panEuropean system. Data was also collected and analysed from an extensive study of the available literature and from in depth semistructured interviews carried out in Norway and Greece. This resulted in a system architecture for a future comprehensive driver information system which consists of 5 different levels. At the lowest level is the individual vehicle and at the highest is the international road network. The intermediate levels are the local, regional and national levels. Each level contains a number of control centres which interchange data horizontally with other centres in the same level and vertically with adjacent levels. This hierarchical structure makes it possible to integrate organizational and technological structures, which are different in each region and country into common functions that can be understood by all drivers in all regions at the individual vehicle level.
Initially a review and analysis of existing systems will be carried out in order to establish the current state of the art. This will take into account all kinds of information systems and research will then concentrate on in-vehicle systems.
Based on both the results of the two above steps and on the results of other DRIVE tasks, recommendations for a pan-European in-vehicle information system will be developed.
In preparing these recommendations following aspects will be explicitly considered:
- legal factors (data protection, legislation)
- public authorities (road, police, etc.)
- distribution channels ( broadcasters, roadside beacons, etc.)
Conflicts between national standards will be highlighted and resolved in the proposed pan-European standard.
Regular liaison with other European initiatives (for example Eureka projects) is planned.
Main Deliverables:
Report on driver information systems, on the strategies for and architecture of driver information systems, final report containing system specifications and recommendations.
