BENEFIT/COST ANALYSIS OF ROAD TRAUMA COUNTERMEASURES: RURAL ROAD AND TRAmC ENGINEERING PROGRAMS

This report represents the results of a study which examined the safety effect of providing sealed shoulders, overtaking lanes, and edge lining on rural highways in Victoria. For shoulder sealing, a statistically significant reduction in casualty accident frequencies was found, equivalent to a 43 per cent reduction on a per vehicle kilometre basis. Comparing economic benefits and costs, a benefit/cost ratio was determined of 2.9 x (AADT in thousands), where AADT is Annual Average Daily Traffic. The study was unable to find any statistically significant effect of overtaking lanes or edge lining on accidents. This report is disseminated in the interests of information exchange.
