[Extract:] The results of previous work have shown that roads with higher geometric standards are safer. In fact the freeways (or motorways) are the safest form of road, being four times as safe as other roads and can be as much as 20 times as safe as other arterial roads (Ogden, 1996, p. 155; Asfa, 2000, p. 2)). In Australia, where population is sparse except in the metropolitan cities, travel demand and economics do not permit all roads to be built to the highest standards. A significant proportion of Australian roads, especially in country areas, have been built to lower standards. Improving design standards will undoubtedly improve safety on roads. The design standards refer to strategic decisions concerning the geometric standards to which the road is built. Such decisions are possible to be made efficiently and rationally if the decision-makers are aware of the effect of improving standards on reducing accident risk.
