|Speed Reduction Treatments for High-speed Environments
This report examines the performance of different types of speed-reducing treatments (or combinations of treatments) in high-speed environments.
|Review of Motorway Entrance Ramp Acceleration Lengths
This report investigates whether the ramp acceleration lengths provided in the Austroads Guides are valid for modern Australian vehicles.
|Road Geometry for Improved Rural Safety
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 with curves, roadsides with narrow offset to roadside hazards, and high-flow rural at-grade intersections. These findings were supported by a before and after evaluation of casualty crash reductions expected from shoulder sealing, pavement widening and road realignment.
|Road Design for Heavy Vehicles
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 intersections to accommodate heavy vehicles. This study examined gap selection at a variety of intersection layouts including two lane and four lane intersections. The results provided a reasonable measurement of the gap sizes due to the low number of heavy vehicles undertaking movements through the intersections.
|Safety Provisions for Floodways Over Roads
This report summarises research into effective ways of alerting drivers to the dangers of crossing a floodway when it is under water.
