Evaluation of Delay on Unsignalized Intersection


In this study, empirical models of capacity and delay and warrant for signalization or improvement had been developed for some types of two-way stop- controlled intersection. The capacity model states that the maximum flow of the minor street is a function of the total conflicting flow. The delay model states that at 100-vph reserve capacity, the average service time tends to remain at a nearly constant level and average service time is a function of total conflicting flow and reserved capacity being fixed. The delay-based warrant states that the intersection is efficient at a combination below the curve of the capacity minus the threshold value of 100-vph reserved capacity.
