Abstract

Describes a study of accidents at 3 and 4 arm mini-roundabouts on two-way 30 mph single carriageway roads, commissioned by the Road Safety Division of the DETR and undertaken by the Transport Research Laboratory (TRL) with the Transportation Research Group at the University of Southampton as a sub-contractor. The main objective of the study was to investigate the frequency and character of the accidents in relation to traffic flow, road features, layout, geometry, land-use and other variables. Accident predictive models have been developed ranging from whole junction total accident models to arm-based full geometric models for individual groups of accidents. The study is one of a series investigating accidents at different junction and link types.
