The project aims to:
- provide comprehensive specifications to enable existing and future road information and management systems to contribute to European needs as well as serve the local requirements;
- ensure appropriate links between the road databases and other related systems, e.g. for vehicle navigation, traffic management, route planning, etc.
Many road administrations and associated consultants within the European community are already well advanced in the process of developing sophisticated spatially related road information and management systems. These systems will not only revolutionise the approach to road safety and the management of the road infrastructure in the 1990's, but could have significant implications for the DRIVE initiative. However, current developments, although all addressing the same broad issues, lack an overall view and generally confine their attention to local or national needs. Therefore, the aim of or the road information and management Euro-system (RIMES) is firstly to examine the situation and establish the high level wider view parameters that all systems could and should incorporate irrespective of frontier. Secondly, the RIMES project will study and develop directives and standards for the construction of the road databases (RDB) for the use of administrations managing a road network.
To attain these objectives, it is proposed to: take an across the board look at current developments followed by an in depth study of the major development sites, identify the information needs of a feasible European system and validate the issued information model on existing RDB implementations and other DRIVE projects issues, produce a road data base conceptual model representing the common real life situation at road administrations, formulate the technical specifications which could enable road administrations to provide information at a European level, identify or develop communication standards for the interchange of information between road databases and the other related developments of the DRIVE programme and formulate guidelines on a classification to define the quality and the accuracy of data in the frame of the interface with otherproducts.
The research led to the design of a road administation data exchange format (RADEF) developed during a specific project. The RADEF was tested against several RDB sites in Europe. A prototype was made available from November 1996.
The aim of the research was to reconcile the already large (but disparate) investment of road administrations in Europe in the domain of road information and management database systems with the requirements of European road transport informatics (RTI) systems. The first stage was the completion of an in depth survey of the current situation within Europe as far as public administrations and RTI are concerned. A picture emerged of a nonuniform spread of activity. There was heavy investment and similar long term objectives but little common as far as a technical database was concerned.
Following the survey a complete data analysis opened the way to the design of a conceptual data model which has been validated against different public administration road databases (RDB). During the same period an evaluation of road network referencing requirements revealed that the emerging Geometric Data File (GDF) standard would be unlikely to fully accommodate all the perceived needs of public administrations. The research led to the design of a road administration data exchange format (RADEF) standard which would be as close as possible to GDF but extended to incorporate the special requirements of public administrations. The combination of RADEF and GDF together would add immeasurably to the contribution and therefore value of the road administration databases within an integrated road transport environment.
To achieve the objectives the project will:
- take an "across the board" look at current developments followed by an in-depth study of the major development sites;
- identify the information needs of a feasible pan-European system;
- formulate the technical specifications which would enable road administrations to provide information at a European level;
- to formulate standards for the spatial relationship of data (network referencing);
- develop communication standards and tools for the interchange of information between road databases and related developments coming out of the DRIVE Programme.
