| Summary: | account in both models. The saturation flow model is based analyzed. and blocking occurs. The model calculates the capacities of as a part of this research predicts the maximum demand at the at paired intersections with multiple upstream and downstream based assumes that upstream movements discharge at their calculated using the reduced effective green period rather capacity. The analytical model on which the methodology is cases. The comparison shows that the models developed compared with that simulated by TRAF-NETSIM for various comparison show that the model predicts throughput better cross street movements are not considered. The analysis demand at closely spaced intersections. The effects of queue downstream intersection. The through movement at the downstream queue extends back to the upstream intersection green period. The model can be used to estimate capacities green periods. The results from the model are compared with Highway Capacity Manual (HCM) delay equation and the delay inter-signal link causes a reduction in saturation flow and interaction between these two intersections are taken into maximum demand depending on the different combinations of movements at the upstream intersection as a reduced effective NETSIM. It is recommended that the models be used to compute normal saturation flow rate or arrival flow rate until the on the Prosser-Dunne model. The presence of queues in the or storage capacity becomes critical and influences the predict values that compare favorably with results from TRAF shows that either the upstream capacity, downstream capacity than the reduced saturation flow. The second model developed The demand from the models is used as input to the 1994 the upper bound for the HCM delay equation for the cases thesis recommends that the capacity of movements be This thesis describes models for saturation flow and maximum throughput are being calculated) are oversaturated. This TRAF-NETSIM simulation results. The results of this upstream and downstream green and storage spacing considered. upstream intersection is assumed to be oversaturated and when movements at the upstream intersection (for which |
