This report draws on literature and crash data analysis to identify and quantify geometric road design elements which contribute to casualty crash occurrence and severity on rural roads, e.g. lack of sealed shoulders, steep downhill grades combined…
This report documents research to further develop probabilistic modelling work undertaken in 2012 and demonstrate the impact the variations in predictions of the main dependent variable, roughness, has on road agency costs (RAC) and vehicle…
Heavy vehicle crashes across Australia and New Zealand continue to be a major road safety issue. There are road design criteria that are not based on the requirements of heavy vehicles and the purpose of this study was to update criteria for…
