Abstract:

Observations of Traffic Flow at certain urban centres are indicating variation in actual Traffic handling Capacity on links and at intersections which may be due to change in Density and subsequent change in Approach Velocity at intersection and Acceleration pattern. For safe and efficient movement of large volumes of traffic on city road network, majority of the intersections are usually signalized. The design, the capacity and operation of a signalized intersection critically depend on and passenger car unit (PCU) and saturation flow. The intersections on urban roads in India cater to heterogeneous motorized traffic along with slow-moving traffic including pedestrians. It is therefore necessary to consider passenger car unit (PCU) and saturation flow for mixed traffic conditions to evaluate the overall operation of signalized intersections. This paper presents the results of the study on analyses of saturation flow rate conducted at signalized intersections with mixed traffic condition in Surat. Traffic volume and speed data collected on urban road of Surat city by using Videographic Technique are analyzed to determine the saturation flow. Observations of traffic flow at certain urban centers are indicating variation in actual traffic handling capacity on links and at intersections, which may be due to change in density and saturation flow. Such situation needs to be evaluated to correctly predict the saturation flow as it is critical for designing signal cycle time and determining actual capacity of the road.
