ACCIDENTS AT THREE-ARM PRIORITY JUNCTIONS ON URBAN SINGLE-CARRIAGEWAY ROADS

The report gives the findings of a study of accident risk based on a national stratified sample of 980 urban three-arm priority junctions on single carriageway roads (2699 personal injury accidents). The study includes roads with 30 mph or 40 mph speed limits and sites with and without pedestrian crossings. Tabulations are given showing accident frequencies, severities and rates by road type and region. The accidents are also tabulated by accident group, road user involvement and number of casualties per accident. The main objective of the study was to investigate the frequency and character of accidents in relation to traffic flow, road features, layout, geometry, land use and other variables. Accident frequencies by accident group were related to the explanatory variables using the techniques of generalised linear modelling. (A)
