Planejamento tático-operacional do tráfego urbano com o auxílio de microssimulação: caso da interseção BR-116 x Av. Visconde do Rio Branco

Abstract

This paper demonstrates the use of traffic microsimulation as a tool to aid in planning the tactical - operational level of the region close to the intersection of Avenida Visconde do Rio Branco and the BR -116 in the city of Fortaleza. Microsimulation INTEGRATION software was used. Input data were obtained on site surveys and on directional researches of vehicle volume. The coefficient of variation of speed was used as a performance indicator and the delays of the intersections of the approaches that rely on centralized traffic lights used by CTAFOR was used as a calibration parameter. These observations delay are provided by the database of the SCOOT traffic signal control system. Changes in the road network have been proposed based on the issues raised in the region, which were organized in a tree of problems according to their potential cause-and-effect. The results suggest that the proposed changes positively influence the flow of Avenida Visconde do Rio Branco in the south to north, but at the expense of the flow of Avenida Pontes Vieira in east-west direction. Final results show a reduction of 8% in the total delay of the vehicles.
