Abstract
Las deficiencias de circulación en la intersección de las calles Alfonso Navarro Cauper y Jiron Putumayo en la ciudad de Iquitos provoca grandes retrasos para conductores y peatones. La presente investigación fijó su objetivo en analizar el flujo vehicular en la zona ya mencionada a fin de optimizar las redes de circulación para el año 2024. Para lograr lo anterior, se planteó: “describir el nivel de saturación del flujo vehicular mediante simulación microscópica”. Se utilizó una metodología de enfoque cuantitativo, del tipo descriptivo y diseño no experimental longitudinal, todo ello a través de técnicas de observación directa mediante cámaras y contadores automáticos de vehículos. Se generó simulaciones con los softwares PTV Vissim y Synchro, a partir de información del aforo vehicular cada 15 minutos en horarios pico. Algunos de los resultados más relevantes incluyen la ruta Putumayo Oeste a Putumayo Este, que registró el mayor volumen de tráfico con picos de 392 vehículos por cada 15 minutos, alcanzando un volumen máximo diario por hora (MDHV) de 1387 vehículos por hora; y la ruta Putumayo Oeste a Cauper Norte, con un MDHV de 782 vehículos por hora. La simulación del Vissim mostró un nivel de servicio tipo “C” con retrasos de más de 35 segundos y velocidades inferiores a 20 km/h durante las horas punta, por lo que, la aplicación del Synchro redujo el tiempo de espera en un 35 % de 68,4 a 44,2 segundos por vehículo y el nivel de servicio de la intersección de “C” a “B”. En conclusión, se encontró evidencia de que la congestión del tráfico en las intersecciones del estudio puede mitigarse sin ampliaciones en las características físicas de las carreteras, mediante estrategias de optimización, como la configuración del ciclo de los semáforos y la redistribución de los flujos. Se logró mejoras superiores al 30 % en los tiempos de viaje.
Flow deficiencies at Alfonso Navarro Cauper and Jiron Putumayo intersection in Iquitos city cause significant delays for drivers and walkers. This study aimed to analyze traffic flow in the aforementioned area in order to optimize circulation networks by 2024. To achieve this the following was proposed: “to describe the level of traffic flow saturation using microscopic simulation.” A quantitative, descriptive, and non-experimental longitudinal design methodology was used, employing direct observation techniques using cameras and automatic vehicle counters. Simulations were generated using PTV Vissim and Synchro software, in terms of vehicle capacity information every 15 minutes during rush time. Some of the most relevant results include the Putumayo West to Putumayo East route, which recorded the highest traffic volume with peaks of 392 vehicles per 15 minutes, reaching a maximum daily hourly volume (MDHV) of 1,387 vehicles per hour; and the Putumayo West to Cauper North route, with an MDHV of 782 vehicles per hour. The Vissim simulation showed a level of service “C,” with delays of more than 35 seconds and speeds below 20 km/h during peak hours, so the application of Synchro reduced waiting time by 35%, from 68.4 to 44.2 seconds per vehicle, and the level of service at the intersection from “C” to “B.” In conclusion, evidence was found that traffic congestion at the intersections studied can be mitigated without expanding the physical characteristics of the roads, through optimization strategies such as traffic light cycle configuration and flow redistribution. Improvements of more than 30% in travel times were achieved.
