A STUDY ON ACCIDENT BLACK SPOTS ON NATIONAL HIGHWAY

Abstract

Around 70,000 persons are killed and 2,80,000 are injured every year in India out of a total number of 3,60,000 accidents occurred on a road network of 3.3 million km. There is an accident every minute and in every 7.5 minutes a person dies in road accidents. The National Highways though constitute less than 2% of the total road network but carry 40% of traffic, however, for 25% of road accidents are occurring on National Highways out of which 34% leads to fatalities and 28% to injuries. The accident Black-Spot is a spot or location on highway where accidents repeatedly occur or a large number of accidents occur during a period of time. In this dissertation, Black-Sports are identified and analyzed by two different methods. These methods are Babkov coefficient Method and speed Profile Method on selected stretches of NH-58. Correlation has been developed between fatality rate (FR) and Babkov's coefficient (K). Correlation has also studied between fatality rate (FR) and speed index (SI). Both methods are compared using statistical test. The results of both the methods are acceptable at 99% confidence level.
