Accident Blackspot Ranking: An Alternative Approach in the Presence of Limited Data
Ranking of accident blackspots for safety improvement works is always a challenging task for traffic professionals. A suitable ranking criterion is very essential to reduce the false positive (a site included in the list when it is not needed) and false negative (a site not included in the list when it is needed) in prioritising the promised sites. Many of the existing blackspot ranking methodologies being used in developed countries require too much of sophisticated and detailed information containing volume, details of geometric design, spot speed details, control measures, etc. that are hardly recorded or accessible in developing countries like India. Hence methods based on the counts/rates of accidents are being widely accepted in these countries, even though they have deficiencies. In this context, a new concept based on the cost of accidents is proposed here. Cost of fatality and injury accidents have arrived through stated preference (SP) choice experiment. These costs are aggregated according to the actual severity distribution at each site and cost of different categories of accidents are calculated for each site. Based on the total economic impact, the blackspots are ranked for improvement. This method involving the evaluation of the real economic burden created by the road accidents at each location may be considered as a better option over traditional blackspot ranking criteria. This study expects that it will rectify shortcomings of the conventional procedures for ranking of hazardous sites.
