In this report the data survey is described and the initial analysis results are provided, concerning major arteries within built-up areas. With these arteries the major roads for through traffic within an urban area are indicated. The risk data are based on road data, traffic data and accident data. No representative files of road characteristics and traffic characteristics were available for the road categories investigated. For the accident data, the Netherlands Transport Research Centre, Department for Statistics and Data Management (AVV/BG) files (including the geographic file on which these data are recorded, the so-called VLN files) were used. The road characteristics were surveyed anew. The traffic characteristics were requested from the municipalities. Recent traffic data, however, was not always available. A number of sample survey areas were selected within which the information from all relevant roads was gathered. The structure and specific VLN properties and its accident files, and the consequences for managing and using the collected data are examined. For the main types of roads and intersections the core data and the computed risks are given. A first comparison is drawn using data collected approximately ten years ago.The involvement of slow traffic and heavy goods vehicles is analysed. See also C 7533, 7534, 7536 anf 7537.
