Capacity is an important on the basis of which other operational measures are calculated for signalised intersections as well as the most widely used concept in traffic engineering practice. This study investigates the capacity of signalised intersection under mixed traffic condition at urban signalised intersection. Estimation of lane capacities of signalised intersection is important factor considered while its planning, design and operation. In this study the effect of vehicle composition in lane on capacity of signalised intersection. A statistical analysis has been performed to understand the relationship between capacity and its number of lanes. In this study, data has been collected at IIM circle and Pakwan Chaar Rasta in Ahmedabad city using videography and data extraction has been carried out using AVIDEMUX software. Vehicle composition of each lane has been obtained by data extraction from videography and effect of each lane on capacity of signalised intersection has been studied. Lane wise capacity has been converted into PCU/hr which further compared with Vehicle/hr. Adjustment factor for 2W has been calculated and capacity model has been prepared based on effect of vehicle composition of lane on signalised intersection. This study concluded that effect of vehicle composition on capacity of signalised intersection and also result show the relation between VPH and PCU.
