Calibração do modelo de aceitação de brechas em interseções urbanas com o microssimulador de tráfego VISSIM

Abstract

The main objec3ve of this paper is to propose a method to model gap acceptance in urban two-way STOP-controlled intersec3ons using VISSIM microscopic simulator. The proposed method is based on the 3me that the driver takes in the process of gap ac-ceptance, that is, on the 3me that the vehicle stays in the first posi3on of the queue. The χ2of the adherence between the wai3ng 3mes’ distribu3ons (simulated and ob-served) and the difference between the means were used for the cri3cal gap es3ma3on. The proposed method was applied to an intersec3on located in Fortaleza city. The re-sults indicated slightly different cri3cal gap values between turning movements. The sec-ond objec3ve of this paper is to compare the proposed calibra3on procedure with the conven3onal one, in which the calibra3on target is a traffic measure of effec3veness, such as the average queue length. The proposed method yielded beDer results.
