This report documents the findings from a research study, which aimed to investigate driver behaviour and perceptions while driving through a simulated version of the Sydney NorthConnex (NCX) road tunnel and evaluate the effectiveness of aesthetic…

This report documents the findings from a research study which aimed to validate the use of a virtual reality (VR) driving simulator to study driving behaviour in a real road tunnel.

This report evaluates selected low-cost perceptual countermeasure (PCM) treatments in tunnel environments. PCM treatments are used to reduce crash risk by improving driver speed behaviour, alertness and lane discipline within tunnels. Two key…

This report provides guidance on consistent, efficient and safe design of emergency egress signage and operations in road tunnels. While there are Australian Standards relating to emergency egress signage, these were not originally intended for use…

Guidelines and Specification for Microsurfacing provides guidelines for the use of microsurfacing treatments in Australia. Microsurfacing is presently the only type of bituminous slurry surfacing applied in Australia. The document was produced by…

An existing model predicted binder life by combining a binder hardening (increase in viscosity) model and a distress viscosity model. Inputs for the two models were site temperature parameters, binder durability (resistance to hardening) and seal…

An existing model predicted maximum seal life by combining a binder hardening (increase in viscosity) model and a distress viscosity model. Inputs for the two models were site temperature parameters and binder durability (resistance to hardening).…

The report summarises the activity in the Austroads sprayed seal design project for 2003/2004. Austroads member authorities were surveyed to determine if there were further issues with sprayed seal design that needed resolution. Recommendations for…
