Abstract
A rapid growth in automobile vehicles is being experienced in recent years in India, which is having heterogeneous traffic like other developing countries. It has made a very complex job for the research professional to understand the traffic behaviour, in the context of transportation engineering with the virtue of its heterogeneity. Urban intersections are always been the most vulnerable point of the transportation networks and the traffic situations becomes worst and chaotic there. Hence, it is of prime requisite to improve the traffic management and facilities available at traffic intersection. Saturation flow rate is the most important parameter to examine the delay, capacity and level of service at intersection. The Highway Capacity Manual (HCM) has provided the equation to calculate the saturation flow rate but it can’t fit well the mixed traffic of developing countries. This paper suggested a new linear model based on the width of approach road to calculate the saturation flow rate of urban traffic intersection for heterogeneous traffic and it predict the saturation flow rate fairly good.
