LAYOUT AND DESIGN FACTORS AFFECTING CYCLE SAFETY AT T-JUNCTIONS

This paper describes an investigation of cyclists' safety at priority- controlled T-junctions, which account for a significant proportion of injury accidents to cyclists. Previous classification studies have identified six main types of junction-related accidents. About 30% of cycling injury accidents at T-junctions involve a motor vehicle, emerging from a minor road, conflicting with a cyclist on the major road. In the present study, accident and control sites were identified and then surveyed. Information was collected about: (1) junction geometry and layout; (2) traffic count data; (3) driver behaviour. Seven differences in geometry were found between accident and control groups, of which the most significant concerned the wider entry of the minor arm at the accident sites. Accident sites were generally found to have more traffic, especially from the minor road. Visibility from the minor road to its right side was significantly better at accident sites. The authors recommend that a review of entry treatments be made, with a view to identifying appropriate measures to be applied at junctions with high main-road cycle flows expected. It is possible that good visibility at junctions should be accompanied by traffic calming or speed reduction measures on entry. Behaviour of drivers entering from a minor road could affect accident potential.
