Samenvatting
The report gives the findings of a study of accident risk based on a national stratified sample of 433 3-arm and 4-arm, priority and signal junctions having one or more one-way arms on 30 miles/hr urban roads. A total of 3,622 personal injury accidents were recorded at the junctions over the period 1987-1994. Tabulations are given showing accident frequencies, severities and rates by junction type. The main objective of the study was to develop relationships between accident frequency and vehicle and pedestrian flows, features, layout, and signal control variables, using the technique of generalised linear modelling.
