Abstract

The main objective of this paper is to propose a method to model gap acceptance in urban two-way STOP-controlled intersections using VISSIM microscopic simulator. The proposed method is based on the time that the driver takes in the process of gap acceptance, that is, on the time that the vehicle stays in the first position of the queue. The c2 of the adherence between the waiting times’ distributions (simulated and observed) and the difference between the means were used for the critical gap estimation. The proposed method was applied to an intersection located in Fortaleza city. The results indicated slightly different critical gap values between turning movements. The second objective of this paper is to compare the proposed calibration procedure with the conventional one, in which the calibration target is a traffic measure of effectiveness, such as the average queue length. The proposed method yielded better results.
