Two Wheeler Adjustment Factor to Estimate Queue Length at Signalized Intersection under Heterogeneous Traffic Conditions

Abstract

The two-wheeler adjustment factor derived in the present study to predict queue length at approaches of signalized intersections in mixed traffic conditions. The statistical distribution investigation carried out to understand the queuing behavior by using observed queue length obtained from the field. Field data was collected at Suchitra and KBR park intersections in Hyderabad City by using video graphic technic. Highway Capacity Manual (2010) adopted for estimating queue length with adjustment of saturation flow rate model given in the manual. Average number of vehicles in the queue estimated by using Highway Capacity Manual (2010) methodology with and without application of two-wheelers adjustment factor to saturation flow rate model given in the manual. The estimated queue length by using Highway Capacity Manual (2010) methodology with and without application of two-wheelers adjustment factor was compared with observed queue length obtained from the field. The comparative study showed the significance of adjustment factor for two-wheelers high for estimating queue length accurately
