This report identifies road design improvements to better cater for the safe passage of heavy vehicles through railway level crossings.

This report provides a compendium of recent and robust evidence on the relationships between twenty key geometric design criteria and safety outcomes.

The project critically reviewed quality research sources to identify crash modification factors…

This report investigates how the geometric design components of a roundabout may contribute to bicycle crashes.

This report proposes a new rule for inclusion in the Performance Based Standards scheme, adding a requirement for applicant vehicles to meet a minimum level of auxiliary braking performance. The purpose of the new rule is to ensure that PBS vehicles…

Chronic excessive sleepiness and accidents caused by sleep-related fatigue are major issues for Australian heavy vehicle drivers. This report examines the importance of sleep-related fatigue and its role in heavy vehicle accidents. Unlike many other…

The design and general operation of heavy vehicles in Australia is controlled by Australian Design Rules (ADRs) and separate regulations within each jurisdiction. The regulations provide control over mass and dimension limits, and the ADRs address a…

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.…
