Abstract: Saturation flow rate plays a major role in the performance evaluation of a newlinesignalized intersection. In urban areas, the multi-modal traffic environment affects the newlinesaturation flow rate. In the present study the Indian urban traffic is grouped into two newlinecategories based on the maneuverability namely Highly Maneuverable Vehicles newline(HMV) and others. Those vehicles which have a high degree of lateral and newlinelongitudinal freedom are called Highly Maneuverable Vehicles (HMV). Motorized newline2/3 wheelers and human powered bicycles are grouped under this category in the newlinepresent study. Saturated green time studies are conducted at selected signalized newlineintersections of Hyderabad city and the data collected is analysed for the saturation newlineflow rates. The analysis established that the saturation flow rate depends not only on newlinethe width available for the movement under consideration but also on the proportion newlineof HMV in the traffic. newlineThe study resulted in the development of statistical models to explain the newlinerelationship between the saturation flow rate in veh/hour and the two independent newlinevariables, the width available for movement and the proportion of HMV. It is newlineobserved that the saturation flow rate increases with the increase in any of the two newlinevariables. A parameter called Saturation Flow Ratio is introduced in the study. This newlinerepresents the saturation flow rate per meter width and the units are veh/hour/m. newlineSaturation Flow Ratio reflects the longitudinal and lateral adjustments exhibited by newlinethe vehicles over varied widths. When the width available for movement is small, the newlinevehicles are observed to move close to each other forming a dense platoon, thereby newlineincreasing the Saturation Flow Ratio. When the width available is large, the vehicles newlinemaintain more comfortable spacings resulting in low Saturation Flow Ratio. Evidently newlinethe high proportion of HMV is responsible for such a behaviour. An artificial neural newlineii newlinenetwork model is developed as a part of the study. The model is formulated in newlineC language. The model is capable of predicting the Sa
