Road Safety

Austroads has recently completed a project that investigated road-based treatments as a perceptual countermeasure (PCM) to influence motorcyclist perceptions of speed and lane width in order to incentivise a safe approach when negotiating critical curves on regional and rural roads.

As part of the project, a trial was conducted to assess whether a specifically designed lane marking layout can alter travelling speed and/or lane position of motorcyclists when negotiating curves along rural roads on a recreational riding route. The trialled PCM was a modified version of a peripheral transverse line marking, characterised by incrementally wider painted blocks through the curve apex. The trial was conducted at two curves characterised by either high or low curvature along Mt Mee Road, a popular motorcyclist recreational riding route in Queensland with a known crash history.

This webinar, presented by Dr Mario Mongiardini and Dr Tana Tan, provides a detailed overview of the project and its findings.
