THE EFFECT OF PAVEMENT CONDITION ON HIGHWAY ACCIDENTS . PROCEEDINGS INTERNATIONAL CONFERENCE ON NEW WAYS AND MEANS FOR IMPROVED SAFETY, TEL AVIV, ISRAEL, FEBRUARY 20-23, 1989

A systematic investigation has been made to relate traffic accidents to pavement condition. This was done within the framework of a cost benefit analysis of the investment for maintaining the rural highway network of Israel. When dealing with the problem at the network level, the results showed no significant relationship between pavement condition and its traffic safety. On the other hand, when testing specific highway sections, it was found that within certain geometric and traffic characteristics, highway safety improved with the increase of pavement conditions rating. Typical examples of this trend are related to the decrease of traffic accidents on specific road sections caused by local pavement improvement, such as: overlaying the pavement surface; and the improvement of skid resistance and shoulder pavement. The paper describes quantitatively some examples where the improvement of pavement conditions produced a reduction in the number of traffic accidents of up to 40%. Emphasis is given to the reduction of accidents related to skidding in wet conditions. At local level it was found that by using a proper anti-skidding asphaltic overlay on critical road sections, it was possible to decrease traffic accidents by 8-10%. The major conclusion of this work is that the effect of pavement condition upon safety is only significant if efforts are concentrated on improving the worse roads, rather than trying to improve the whole road network. By doing this the optimal cost/benefit ratio of pavement improvement can be achieved. (TRRL)
