Abstract :

The main objective of this paper is to apply a probabilistic procedure for evaluating the safety effectiveness of pavement marking of rural and urban roads. Eighty seven sites (stations) are selected from the population of improved roads in Trichy, Pudukottai and Thanjavur districts of TamilNadu state in India. To eliminate the effect of regression to the mean, a Bayesian approach is adopted to eliminate the expecting accident rates in the two periods. Results of the analysis indicate that the beta distribution adequately fitted accident reduction factor frequencies at all sites (three districts). Irrespective of their accident experience, no statistical significant safety impact is observed. Hence the pavement marking does improve the safety of hazardous sites on urban and rural roads. Key words: Number of Accidents, Traffic flow, Pavement Marking, Accident rate, Accident Reduction Factor, Hazardous sites.
