Road accidents are a serious global problem with more than one life lost every minute. Globally road accidents are one of the leading causes of death for young people accounting for 15 percent of deaths in 5 to 44 years age group. This research work is focused on road accidents at identified black spots on National Highway-5 passing through the state of Andhra Pradesh where accidents cluster. After conducting field visits, deficiencies in road design were identified and remedial measures suggested with particular reference to sight distance, horizontal curvature, obstructions along the highway and junction design. This research work revealed that accidents at black spots can be prevented through better design of roads as there is relationship between speed and road geometry. Keywords: Road accident, Black spot, National Highway, Traffic, Accident Rate.
Road transport deserves a high priority compared to other modes of transport like water transport and air transport, as it can effectively meet the demand for transport arising out of growing economic, social, health, cultural and religious needs of the people. The interaction between the level and pattern of transport resources and the average level of living of the population of an area is a critical factor affecting economic and social progress. Rapid industrial urban revolution has lead to increase in the number of vehicles and consequent traffic congestion and increased number of accidents.
Road safety is a serious global problem with more than one life is lost every minute.

While the situation is improving in developed countries, less developed countries are experiencing increased number of road accidents. Several less developed countries have death rates per 10,000 vehicles, which are 20 times those of developed countries. Accidents are due to culmination of more than one factor. Road user error is identified as the most common factor but engineering measures the road vehicle environment easier to deal with and reduce road user error and improve road safety situation. This research work deals with identification of black spots where accidents cluster and remedial measures to be adopted to reduce the occurrence of accidents.
Road Accidents – Global Scenario
Detailed analysis of global accident statistics by Transport and Road and Research Laboratory, U.K, indicate that fatality rates per licensed vehicle in less developed countries are very high (20 to 30 times) in comparison with the developed countries. Between 1968 and 1985, the number of deaths increased by over 300% in African countries and by over 170% in Asian countries, where as, in the developed countries over the same period, the number of persons killed actually declined by 25%. From 1985 to 2008, the same trend as obtained above was observed. The number of deaths increased from 300% in 1985 to 340% in 2008 in African countries and from 170% 1985 to 230% in Asian countries, where as the developed countries experienced further slide from 25% in 1985 to 30% in 2008. Table-1 shows that globally, road accidents are one of the leading causes of death for young people accounting for 15% of deaths in 5 to 44 years age group. The approaches used by developed countries for accident reduction would also seem to have considerable potential for developing countries as shown in Table -2. In particular, it is recommended that countries with limited resources should place...
