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 project forms part of an ongoing Austroads strategic research program to improve the understanding of the relationship between crash risk and road elements. This report provides a summary of the relationship between crash risk, and geometric…

Passive control railway level crossings within the road network pose a significant safety issue, both for trains and multi-combination vehicles (MCVs) and restricted access vehicles (RAVs0. In order to have provision for the larger MCVs and RAVs,…

This project had its origins in an earlier project which showed that crash rates increased at extremes of horizontal and vertical geometry, and were lowest with narrow sealed shoulders. This paper reports an investigation based on the original…

This project has involved the collection into a single database of all available WIM data and the interrogation of that database to provide information on speed and mass compliance by two selected vehicle types Results of this work must be treated…

While truck tracking characteristics are a primary consideration for intersection geometry and curve widening practices, most road geometric design standards, particularly alignment design standards, are based on the performance characteristics of…

A Weigh-in-Motion (WIM) system is defined as a device that measures the dynamic axle weight of a moving vehicle to estimate the corresponding static axle mass. This report documents the status of WIM technology, focusing on Australia's situation.…

This paper reports a study which brings together information on road geometry (curvature and grade), cross-section, traffic flow and crashes. It allows the influence of these other factors on road crashes to be assessed in ways not possible before.…

The Review of Axle Spacing/Mass Schedules report covers vehicles conforming to RoRVL Option C axle mass limits in the General Access and Restricted Access classifications proposed by Austroads. The report`s considerations and recommendations only…
