Compatibilidad de dos metodologías para la mejora de intersecciones no semaforizadas peligrosas en el distrito de El Tambo, Huancayo-Junín 2018

Camayo Armaulia, Cristian Maicol 17 May 2019 (has links)
El presente trabajo de tesis titulado “Compatibilidad de Dos Metodologías para La Mejora de Intersecciones No Semaforizadas Peligrosas en el Distrito de EL Tambo, Huancayo – Junín 2018”, consiste en el análisis de dos metodologías el “Manual de Capacidad de Carretera” (HCM 2000) y el “Manual de Dispositivos de Control de Tránsito Automotor para Calles y Carreteras” del (MTC), en intersecciones no semaforizadas.Finalmente, se llevó a cabo una discusión de los resultados que se muestran en el capítulo 4.3 mediante tres análisis de compatibilidad entre las dos metodologías, para determinar la compatibilidad entre sus resultados; bajo estos tres análisis, se determinó que ambas metodologías proveen una mediana compatibilidad de resultados, mas no en su totalidad, ya que coinciden en las intersecciones I_02, I_03, I_05 e I_06 y discrepan en las intersecciones I_01 e I_04, además de ser metodologías complementarias entre sí.

Determinación de ciclos semafóricos optimizados con Synchro 10.0 aplicados y evaluados en intersecciones de gran congestión vehicular con el software PTV Vissim 9.0 / Determination of traffic signal cycles optimized with Synchro 10.0 applied and evaluated at intersections of high traffic congestion with the PTV Vissim 9.0 software

Este artículo presenta la evaluación del tráfico vehicular en dos intersecciones semaforizadas ubicadas en la ciudad de Lima; una de las principales ciudades del mundo con gran congestión vehicular; mediante un modelo microscópico desarrollado con el software Vissim 9.0. La finalidad de esta investigación es proponer la implementación de un sistema de semaforización inteligente para mejorar los niveles de servicio y disminuir la congestión vehicular. El proceso de construcción del modelo consiste en cuatro etapas. Primero, es el trabajo previo, en la cual se realizó la recolección de datos de campo. Luego, se construyó el modelo mediante el software Vissim 9.0. Después, se realizó la calibración y validación del modelo en ambas intersecciones en base a parámetros psicofísicos para certificar que los resultados del modelo se asemejen a las condiciones reales de las intersecciones. Por último, se incorporaron los nuevos flujos futuros en el modelo cada 15 minutos los cuales se simularon y evaluaron con los NS obtenidos, que incorporan la propuesta de mejora. Esencialmente los niveles de servicio de las intersecciones mejoran, determinando cada 15 minutos durante la hora pico nuevos ciclos semaforizados optimizados con el programa Synchro 10.0 aplicados a Vissim 9.0, pasando de un NS E a D, esto se deduce a partir de la disminución de longitudes de colas en todos los accesos y la reducción de las demoras de viaje, las cuales fueron 14% en la Av. Javier Prado – Ca. Las Flores y 24% en la Av. Javier Prado – Ca. Las Palmeras. / This paper presents the evaluation of vehicular traffic on two signalized intersections located in the city of Lima; one of the world's major cities with high traffic congestion; by microscopic model developed with Vissim 9.0 software. The purpose of this research is to propose the implementation of an intelligent traffic signals to improve service levels and reduce traffic congestion. The process of building the model consists of four stages. First, it is the previous work, in which the field data collection was performed. The model was then constructed by Vissim 9.0 software. After, calibration and validation of the model was performed on both intersections based on psychophysical parameters to certify that the model results resemble the actual conditions of intersections. Finally, new future flows were incorporated into the model every 15 minutes which were simulated and evaluated with the NS obtained, incorporating the proposed improvement. Essentially service levels intersections improve, determining every 15 minutes during rush hour new signalized cycles optimized with Synchro 10.0 program applied to Vissim 9.0, from an NS E to D, It follows from decreasing lengths queues at all entrances and reducing travel delays, which were 14% at Av. Javier Prado -. Ca. Las Flores and 24% on Av. Javier Prado -. Ca. Las Palmeras. / Trabajo de investigación

Comportamento dos motoristas em interseções semaforizadas / Driver behavior at signalized intersections

Colella, Diogo Artur Tocacelli 29 February 2008 (has links)
Esta pesquisa caracterizou o comportamento de motoristas em interseções semaforizadas sob três aspectos: (1) reação frente à mudança do verde para o amarelo; (2) comportamento durante a desaceleração para parar; e (3) comportamento durante a saída do cruzamento semaforizado. Os dados foram coletados em uma interseção localizada em pista de testes no Virginia Tech Transportation Institute, nos EUA. A amostra foi composta por 60 motoristas voluntários igualmente divididos em função do gênero; dos quais 32 tinham idade inferior a 65 anos (\"jovens\"). Foram investigados efeitos da idade, do gênero e da declividade da via sobre as seguintes situações: tomada de decisão entre parar ou prosseguir no amarelo; posição de parada em relação à faixa de retenção; tempo de percepção e reação (TPR) para frenagem e partida do cruzamento; efeito de zonas de opção e de dilema; taxa de desaceleração para parada na interseção; e taxa de aceleração para partida da interseção. As análises indicaram que: (1) os motoristas mais jovens invadiram mais a faixa de retenção que os idosos; (2) mulheres apresentam maiores TPR para decidir partir da interseção; e (3) o TPR é menor no declive tanto para a decisão de frear quanto para a partida do cruzamento. As taxas de desaceleração não apresentaram influência dos fatores avaliados. Por outro lado, constatou-se que a aceleração foi afetada pelo fator declividade. Como resultado final da pesquisa, foram propostos modelos, em função do tempo, que exprimem a desaceleração/aceleração usada pelos motoristas ao frear/acelerar. Foram propostos modelos para o motorista médio e para motoristas desagregados em três grupos em função da agressividade. / The objective of this research was to characterize driver behavior at signalized intersections according to three aspects: (1) reaction at the onset of the amber phase; (2) behavior during the deceleration to stop at the signal; and (3) behavior during the acceleration to leave the intersection at the onset of the green. The data were collected at a signalized intersection on a private highway, at the Virginia Tech Transportation Institute, in the USA. The sample consisted of 60 volunteer drivers, equally divided by gender. The sample was divided into two age groups: younger drivers (age was less than 65) and older drivers. Effects of gender, age group and roadway grade were investigated for the following aspects: decision making at the onset of amber; final stopping position with relation to the stop line; perception/reaction times (PRT) at the onset of the amber and the green lights; effects of dilemma and option zones; and deceleration and acceleration rates used by the drivers. The analyses suggest that: (1) younger drivers tend to stop farther past the stop line, compared to older drivers; (2) women have longer PRT at the onset of the green; and (3) PRT are shorter on downgrade at the onset of both amber and green lights. The observed deceleration rates were not affected by gender, age group or roadway grade. Acceleration rates were found to be influenced by the grade. A set of models that express the acceleration/deceleration rates as a function of time were proposed to represent the average behavior observed for drivers in the sample. Specific models were also proposed for aggressive, non-aggressive and intermediate drivers.
