A multidisciplinary investigation of the influence of the built urban environment on driver behaviour and traffic crash risk

The overall aim of this thesis was to develop and apply a multidisciplinary approach to identify and understand the aspects of the built urban environment that influence crash occurrence. Research Component 1 of this thesis sought to identify characteristics of the built environment that were associated with crashes on complex urban roads. A comprehensive list was developed of characteristics of the built urban environment that were potential risk factors for crash occurrence. A cross-sectional study was conducted using a novel phased modelling approach. It identified that, in addition to traffic exposure and road design, the roadside environment and facilities and amenities were associated with the frequency of multi-vehicle, single-vehicle and pedestrian-vehicle crashes on strip shopping centre road segments in metropolitan Melbourne. Risk factors differed by crash type. Research Component 2 of this thesis comprised a case study to demonstrate how behavioural research methods may be employed to investigate the behavioural mechanisms underlying crash risk. Driving simulation was used to investigate the effect of roadside parking (identified as a risk factor for multi-vehicle crashes in Component 1) and speed limit on driver behaviour. Recommendations for countermeasures to address crash risk on urban roads with roadside parking were made. This thesis demonstrates a rigorous scientific process for applying two complementary methodological approaches to identify risk factors for crashes and understand their mechanisms. The innovative contribution of this thesis was the synergistic combination of cross-sectional modelling and driving simulation to identify and further investigate risk factors for crashes. Implications for future road safety research and practice were discussed.
