Abstract:

In India, Traffic consists of all type of motorized and non-motorized vehicles. All vehicles are of different static and dynamic characteristics. Traffic flow consists of different classes of vehicles and no lane is followed. The traffic management becomes very difficult due to higher growth rate of vehicles and non-availability of sufficient space in urban area. It leads to congestion, excessive delay and accidents on urban roads. All types of vehicles are converted into Passenger Car Unit (PCU). Due to fundamental differences in operating conditions on road and vehicles, the standard western relationships for predicting the saturation flows are not appropriate for countries like India. The existing model of Saturation flow estimates lower value of saturation flow compared to field saturation flow. Capacity is a key parameter for planning, design and operation of any type of urban roads. In the present study, Saturation flow and Capacity of mid-block section of urban roads are studied. It is necessary to develop the relationship between saturation flow and capacity at mid-block section of urban roads. In present study, the saturation flow is developed considering width and composition of various type of vehicles for the selected stretches of Ahmedabad city. The speed-flow relationship is developed for selected stretches of Ahmedabad city. The relationship is developed between saturation flow and capacity of mid-block section of urban road. The width of road and observed capacity are considered as variable, which are significantly affecting on saturation flow. The developed models are validated using statistical‘t’ test.
