摘要

Estimation of delay in signalized intersection is a difficult and complicated process that depends on many variables. Among the factors influencing the intersection delay, variable of saturation degree (Xc) is one of the most important variables. In the present study, a new analytical method has been proposed for calculating delay variation at isolated intersections in under-saturated condition and under the influence of different number of vehicles entering to the intersections. Generally, the average delay for average number of vehicles entering intersection is currently calculated by the point to point method; then, the level of service of intersection is specified from the resulting delay. In the meantime, the influence of different number of vehicles entering to the intersections cannot be seen in such methods. But for the presented method in this paper the delay is expressed as a range of values for different values of saturation degree and different numbers of vehicles entering the intersections that it leads to achieve more real results from intersection's level of service.
