Abstract

A review of the crash history has identified that the run-off-road crash is one of key crash types in Queensland, Australia. Hazards on both sides of a carriageway are identified a potential risk exposed to road users. As such, a proper roadside design plays an indispensable role to ensure a more forgiving road environment in order to reduce the likelihood and severity of run-off-road crashes. To assist road engineering practitioners in roadside design, the Queensland Department of Transport and Main Roads (TMR) developed a software application - the Roadside Impact Severity Calculator (RISC), however the applicability of RISC for developing the road safety improvement program needs to be evaluated through gaining a greater understanding of the correlation between the severity index and the crash reduction factor. Accordingly a desktop study is conducted to investigate safety barrier options with assistance of RISC.
