The Saturation Flow is the flow which would be obtained if there was a continuous queue of vehicles and they were given a 100 per cent green time. It is generally expressed as P.C.U per hour of green time. Saturation flow depends on the layout of the intersection (especially the width of the approach road), the number of right turning vehicles and goods carrying (commercial) vehicles, the presence of parked vehicle on the road and other factors. The road width of approach is assumed to be constant for at least the length of the approach road which is defined as the length of road which will accommodate the queue which can just pass through the intersection during a fully saturated green period. In connection with the saturation flow formula for the change in approach road width, observations were held at three signalized intersections of Visakhapatnam city, they are, Asilmetta junction, RTC Complex Junction, and Sangam Sarath Junction. In this study, the approach road width loss due to vehicles parked near the Signal intersections at busy and major Visakhapatnam areas are considered and this loss is updated in the approach road width value to be used in the Saturation flow formula and consequently the empiricism of the Saturation flow formula is updated to suit the Visakhapatnam area Signal intersection designs.
