SPEED-VOLUME STUDIES ON RURAL HIGHWAYS IN INDIA

As a part of road user cost study, a research project sponsored by the World Bank and the Government of India, a detailed investigation has been carried out on one of the most important components of traffic flow research, i.e. speed-flow relationships on different categories of rural highways in India. Published results from abroad may not be applicable to behaviour of traffic under typical Indian conditions. In the absence of research in India, the highway planners had often to be content with ad hoc norms of capacity based on experience abroad. The road user study presented the first opportunity to collect extensive data in India and to build speed-flow relationships. A number of test sections were selected for the purpose covering a wide range of roadway geometry, roughness and terrain. Traffic on Indian roads is heterogeneous in character and is composed of slow and fast-moving vehicles. The mix of the wide range of vehicle types, each with its own distinct characteristics such as dimensions and speeds, gives rise to complex behaviour when the vehicles interact with one another. Statistical relationships have been established and will be useful in predicting speeds of different vehicle categories under different conditions of volume and composition. The results will be very useful in development of geometric design standards, selection of speeds for traffic regulations, fixation of norms for capacity of different roads and evaluation of road user benefits.
