Accidents at four-arm single carriageway urban traffic signals
This report describes a study of personal injury traffic accidents occurring during the four years, 1979 - 1982, at a sample of 177 four-arm single carriageway traffic signal junctions on 30 mile/h roads in urban areas of Great Britain. The sample was structured to compare junctions which were (i) operating under UTC or not, (ii) had a pedestrian stage or not and (iii) had two vehicle stages or more than two. Tabulations are given showing accident frequencies, severities and rates by junction category, and of accidents by type, road-user involvement and other characteristics. Generalised linear modelling methods were used to relate accident frequencies by type to functions of the traffic and pedestrian flows and the geometric and control characteristics of the junctions to provide models for examining the effects of such features.

Abstract

This report describes a study of personal injury traffic accidents occurring during the four years, 1979 - 1982, at a sample of 177 four-arm single carriageway traffic signal junctions on 30 mile/h roads in urban areas of Great Britain. The sample was structured to compare junctions which were (i) operating under UTC or not, (ii) had a pedestrian stage or not and (iii) had two vehicle stages or more than two. Tabulations are given showing accident frequencies, severities and rates by junction category, and of accidents by type, road-user involvement and other characteristics. Generalised linear modelling methods were used to relate accident frequencies by type to functions of the traffic and pedestrian flows and the geometric and control characteristics of the junctions to provide models for examining the effects of such features.
