Comparative Study of Methods used For a Capacity estimation of Roads

Nowadays the traffic is increasing rapidly and traffic volume on roads exceeds the normal limit. The traffic conditions on Indian roads are highly heterogeneous in nature due to variety of vehicles with different static and dynamic characteristics. Study of various characteristics of road traffic is necessarily required for the planning, design and operation of roadway facilities. For a increased vehicular it requires better roadway infrastructure with higher capacity. For the capacity analysis of road it is quite difficult to estimate the traffic volume and capacity of roadway facilities under heterogeneous traffic condition. This paper discuss and review the Capacity estimation of roads under heterogeneous traffic condition by various authors and the factors influencing the capacity of roads and parameters affect the capacity of roads is reviewed and studied. This Paper can be used for analyzing different methods used for Capacity analysis of roads to improve the roadway and traffic condition.
