Estudo de implementação e priorização do tráfego de pedestres em inserção semaforizada localizada em Campina Grande - PB, utilizando microssimulador de tráfego.

Abstract

The media over time has consolidated the "need" for people to own automobiles, placing them as icons of freedom and success. This was one of the reasons for the increase in the number of automobiles. Then the increase in the fleet generated discomfort within urban centers due to the lack of adequate planning. Such planning can be carried out through microsimulators, where it is possible to improve the urban infrastructure by modeling real cases and finding parameters to be modified in order to obtain better results at a lower cost for each case. As a result, this work aimed to look for alternatives to prioritize pedestrian crossing at a traffic light intersection located in the city of Campina Grande – PB, using the PTV VISSIM traffic microsimulator. For that matter, two solutions were proposed, the first proposes the implementation of traffic lights for pedestrians that enable two crosswalks on the diagonal of the intersection and the second proposes the prohibition of some of the existing permissions at the intersection, in order to allow the pedestrian to move around with safety. For the first solution, 3 (three) different walking average speeds were used to obtain the additional red times of the traffic lights in which it was necessary for the pedestrian to complete the route. For the second solution, 4 (four) existing permits were removed, which allowed for a comfortable crossing. By establishing the two solutions, the calibration of the real case was started using the calibration parameters for the Wiedemann 99's car following model, which were found in the study by Queiroz Júnior (2020), as well as the characteristics of the intersection such as number of lanes, directions, number of traffic lights. Then, each solution was calibrated and, thus, information was obtained on the average travel time, average queue length and the average number of vehicles in each case. Thus, it can be concluded that Model 1 of Solution 1 had little impact on the average travel time, as well as on the average queue length. And, due to Solution 2, even with better results, a study involving the existing intersections along Avenida Canal is needed, in addition to the one addressed in this study. Therefore, Solution 1 is the one with the most credible results.
