Road accidents are an outcome of the interplay of various factors, some of which are the length of the road network, vehicle population, human population and adherence/enforcement of road safety regulations etc. Road accident causes injuries, fatalities, disabilities, and hospitalization with severe socio-economic costs across the country. Road traffic injuries cause considerable economic losses to victims, their families, and to nations as a whole. Almost 90% of the world's fatalities on the roads occur in low- and middle-income countries, even though these countries have approximately half of the world's vehicles. Half of those dying on the world’s roads are “vulnerable road users”: pedestrians, cyclists, and motorcyclists. Without action, road traffic crashes are predicted to rise to become the 7th leading cause of death by 2030. There are a total of 1, 03,933 km of National Highways in India and out of the total length of 1, 03,933 km of National Highways, 57,511 km is with the State Public Works Departments (State PWDs), 32,155 km with the National Highways Authority of India (NHAI), 1616 km with NHIDCL and 4,550 km with Border Roads Organization (BRO), balance length of 4,642 km is yet to be entrusted to the executing agencies. Although National Highways constitute nearly about 2 percent of the total road network as on 31st December 2015, they carry 40 percent of the total road traffic. The capacity of National Highways in terms of handling traffic (passenger and goods) needs to be in pace with the industrial growth. India has one of the largest road networks of over54.72 lakh km. It comprises of National Highways, Expressways, State Highways, and Major District Roads, Other District Roads and Village Roads as shown below.
