Resumo: Traffic light intersections tend to be the most problematic places in the road systems, as they present high levels of congestion, accidents, air pollution and high economic losses. With this, the methods and models that provide knowledge of the efficiency parameters of the operation become more and more protagonists in the management of urban traffic. However, the availability of different methods and models can lead to divergence between the parameters within the same intersection. Thus, this study aims to analyze how the application of statistical tests allows the identification of relevant instruments for traffic management. The methodology consists of using two VISSIM and Simtraffic simulators, and the Webster method to obtain the parameters of operation efficiency, average delay and the queue length of the tail of a traffic light intersection with three accesses. For the analysis of the parameters, taking into account different methods and models, in three traffic light cycles, the statistical tests of ANOVA and Mann-Whitney were applied. The results show the importance of applying these tests to improve urban traffic management, since these tests determine whether the operational efficiency parameters differ according to the scenario, methods and software applied.

Con ello, los métodos y modelos que proporcionan el conocimiento de parámetros de eficiencia de la operación se vuelven cada vez más protagonistas en la gestión del tránsito urbano. Sin embargo, la disponibilidad de diferentes métodos y modelos puede producir divergencia entre los parámetros dentro de la misma intersección. Por tanto, este estudio tiene como objetivo analizar como la aplicación de pruebas estadísticas permite identificar instrumentos que son relevantes para la gestión del tránsito. La metodología adoptada consiste en utilizar dos simuladores VISSIM y Simtraffic, y el método de Webster para obtener los parámetros de eficiencia de la operación, demora promedio por vehículo y la longitud de la cola de una intersección semaforizada con tres accesos. Para el análisis de los parámetros, teniendo en cuenta los diferentes métodos y modelos, y los tres ciclos semafóricos, se aplicaron las pruebas estadísticas de ANOVA y Mann-Whitney. Con los resultados se observa la importancia de aplicar estas pruebas para la mejora de la gestión del tránsito urbano, dado que dichas pruebas determinan si los parámetros de eficiencia operacional difieren según el escenario, métodos y software aplicado.As interseções com semáforos tendem a ser os locais mais problemáticos do sistema viário, pois apresentam elevados níveis de congestionamento, acidentes, poluição do ar e grandes perdas econômicas. Com isso, os métodos e modelos que fornecem conhecimento dos parâmetros de eficiência da operação tornam-se cada vez mais protagonistas na gestão do trânsito urbano. No entanto, a disponibilidade de diferentes métodos e modelos pode levar à divergência entre os parâmetros dentro da mesma interseção. Assim, este estudo tem como objetivo analisar como a aplicação de testes estatísticos permite identificar instrumentos relevantes para a gestão do tráfego. A metodologia adotada consiste na utilização de dois simuladores VISSIM e Simtraffic, além do método de Webster, para obtenção dos parâmetros de eficiência de operação, atraso médio por veículo e comprimento da fila de um cruzamento semáforo com três acessos. Para a análise dos parâmetros, levando em consideração os diferentes métodos e modelos, e os três semáforos, foram aplicados os testes estatísticos ANOVA e Mann-Whitney. Os resultados mostram a importância da aplicação desses testes para melhorar a gestão do tráfego urbano, uma vez que esses testes determinam se os parâmetros de eficiência operacional diferem de acordo com o cenário, métodos e softwares aplicados.Research, Society and Development2022-02-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2617810.33448/rsd-v11i3.26178Research, Society and Development; Vol. 11 No. 3; e0511326178Research, Society and Development; Vol. 11 Núm. 3; e0511326178Research, Society and Development; v. 11 n. 3; e05113261782525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/26178/22936Copyright (c) 2022 Oisy Hernandez Menendez ; Natalia Assunção Brasil Silva; Heraldo Nunes Pitangahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMenendez , Oisy Hernandez Silva, Natalia Assunção Brasil Pitanga, Heraldo Nunes2022-03-09T13:44:38Zoai:ojs.pkp.sfu.ca:article/26178Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:44:16.974823Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
