ROAD SAFETY: CRITERIA FOR COST EFFECTIVENESS

The author puts the view that traditional methods of assessing accident data may work against the maximisation of cost effectiveness of road safety expenditure. He claims that any approach based on accident rate and total is not able to measure the likely accident reduction and neither can be used to rank sites of different character. Evidence suggests that accidents are statistically correlated to appropriate measures of traffic flow, and sites at which accidents happen more frequently than traffic conditions suggest could have deficiencies which could be remedied. The author describes a method used to divide the road network into a series of discrete sites according to its characteristics. For each site with more accidents than the average it should be possible to establish the potential for accident reduction. An example is given to show how the possible remedial action depends upon the pattern of sites with poor accident records, and a different priority rating is given to a given site depending upon the method used to assess potential reductions. Values for accident reduction and expected cost should be calculated for each potential scheme investigated. (TRRL)
