Designing safer roads to combat driver errors: rural crashes

The incidence of serious casualty run-off-road crashes in rural Western Australia is significant. Driver behaviour including inadvertent error and deliberate unsafe behaviour compound this issue. Many countermeasures were identified in the literature to address driver error in WA along remote and regional areas. These ranged from perceptual countermeasures such as transverse lines and wide centreline marking to physical measures such as rumble strips and increased lighting. A taxonomy was developed to link the areas of concern with respect to road design and driver error, with available countermeasures.
