ESTIMATION OF SATURATION FLOW AT SIGNAL CONTROLLED JUNCTIONS AT KARACHI (CASE STUDY)

Experimental research conducted for estimation of saturation flow at signal-controlled junctions is presented. Data was collected by videotape at 9 different approaches of 4 signalized intersections in Karachi, Pakistan. The videotapes were played in the lab to abstract information on the headway of the vehicles in saturated cycles. The analyses of pcu values were carried out by comparison of the average passenger car headway to the average headway of other vehicle types. As per methodology of Road Note No. 34, the saturation flow was measured at all the sites by counting the number of vehicles crossing the stop line in 6 second intervals. The MINITAB statistical analysis package was used to obtain a relationship between saturation flow and approach width. The developed relationship is slightly different from the RRL's formula.
