Abstract

cognitive work analysis intersections drivers motorcyclists cyclists road safety pedestrians
Collisions at intersections represent a significant road safety issue worldwide but have seen little reduction in casualties and serious injuries over the past decade. This is partly because research and countermeasures have focussed on specific road user types or design components in isolation and has failed to consider the complex interactions between different road users, vehicles and infrastructure and the resulting implications for intersection design. Cognitive work analysis (CWA) is proposed as an appropriate framework to do so; presenting a systemic analysis of the behaviour of drivers, motorcyclists, cyclists and pedestrians, and the interaction with vehicles and infrastructure at intersections. The results indicate that the framework is suited to identifying differences in constraints, functions and behaviour across different road user groups. CWA therefore provides a suitable systems approach to aid the design of a road system that supports a variety of different road users. The implications for road design and future applications are discussed.
