Road Trauma

ARSC conference 2017

Main Roads Western Australia's traditional approach for developing the rural state road network is to plan road cross sections based on existing standards for the anticipated level of traffic flow. However, this approach may not necessarily deliver the reduction in killed and serious injury (KSI) crashes required by the State Government's Road Safety Strategy Towards Zero (ORS, 2009). Through development of a cross section tool incorporating KSI crash reduction factors for various countermeasures, it has been possible to first evaluate and then improve the proposed rural single carriageway cross sections, thus delivering greatly improved safety, maintenance and cost outcomes.
