Abstract:

One of the main challenges in development of pedestrian safety programs is selection of engineering crash treatments leading to the most effective reduction in number of pedestrian crashes. This approach relies on accurate quantification of the effectiveness of such treatments. This study conducted a literature review of the effectiveness of different pedestrian treatments in Australia and in other countries. This literature review assessed the availability and accuracy of reported crash modification factors (CMF) for each treatment type. Then, four major treatment types which have not been evaluated accurately, were selected for evaluation. These treatment types included ‘median’, ‘kerb extension’, ‘full-time fully controlled right turn signals’ and ‘part-time fully controlled right turn signals’. A quasi-experimental before-after treatment/control evaluation design was utilized to assess the effectiveness of these treatment types. Required data for treated and control sites were collected from Local Government Areas (LGAs) and VicRoads from Melbourne metropolitan area. A log-linear Poisson model was applied to estimate effectiveness of each treatment. The key findings were that median (flush or physical) CMF for all casualty crashes was 0.6 5, and 0.45 for pedestrian casualty crashes. For kerb extensions the all casualty crash CMF was 0.46. For the full-time application of fully controlled right turns, the all casualty crash CMF was 0.48, and for part-time application of the same treatment the CMF was 0.89 (low significance). Outputs of this study will improves the cost-effectiveness and accuracy of pedestrian road safety treatment programs through updated and more accurate CMF values for the most effective and relevant pedestrian safety treatments.
