Computer-Assisted Emergency Evacuation Planning Using TransCAD: Case Studies in Western MassachusettsAndrews, Steven P 01 January 2009 (has links) (PDF)
Disasters, ranging from manmade events to natural occurrences, can happen anywhere on the planet, and their consequences can range from economic loss to catastrophic loss of life. Determining how the transportation system fares in the face of these disasters is important so that proper planning can take place before, rather than after, an event has happened. Modeling the transportation system gives operators the ability to discover bottlenecks, to determine the possible benefit of using lane reversals, and to find out the influence of evacuation speed on system efficiency. Models have already been created that are able to model some of these types of disasters with some level of accuracy. These models range from microscopic simulation to regional, macroscopic models. This research examines how an off-the-shelf regional modeling software package, TransCAD, can be used to model emergency evacuations. More specifically, this thesis presents four case studies involving three different types of disasters in Western Massachusetts. Because this research documents a first-hand experience using TransCAD in emergency evacuation planning, the results give regional modelers the ability to modify their models to fit their specific region. These case studies demonstrate how the modified inputs and existing portions of the four-step transportation planning model can be used in place of the usual data demands of the software. Dynamic traffic assignment is used in three of the case studies while the fourth case study uses static traffic assignment. An evaluation of the software package along with lessons learned is provided to measure the performance of the software.

Aplicação da logística urbana na modelagem e simulação de corredores do transporte público por ônibus / Application of logistics in urban modeling and simulation of corridors for public transport busesSolon, Alexsandro Silva 23 March 2012 (has links)
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / The aim of this paper is to model and simulate the behavior of transit in corridors of public transport by bus based on city logistics concepts using the tools of ARENA and TransCAD softwares. The bus lane used in the case study is the Avenida João Naves de Ávila, in Uberlândia (MG). To model the corridor tried to establish the equilibrium demand / supply ensuring the level of service with a maximum capacity of 80 persons and also used the concepts of city logistics for analysis, simulation and scenario generation. The model considered the arrivals and departures of passengers and the movement of buses in the corridor. These data resulted in the simulation of the corridor as passenger demand and service level adopted in the peak hour. As conclusions noted that the objective was fully achieved and the values of travel time and loading at peak hour in the ARENA software were very similar to those obtained in TransCAD. / O objetivo deste trabalho é modelar e simular o comportamento do transporte público em corredores de transporte público por ônibus com base em conceitos da logística urbana utilizando ferramentas computacionais dos programas ARENA e TransCAD. O corredor de ônibus utilizado no estudo de caso é o da Avenida João Naves de Ávila, em Uberlândia (MG). Para modelar o corredor procurou-se estabelecer o equilíbrio demanda/oferta garantindo o nível de serviço com lotação máxima de 80 pessoas e, também, utilizou-se os conceitos da logística urbana para análise, simulação e geração de cenários. A modelagem considerou os embarques e desembarques de passageiros e o deslocamento dos ônibus no corredor. Esses dados proporcionaram a simulação do corredor conforme demanda de passageiros e nível de serviço adotado na hora de pico. Como conclusões, o modelo mostrou-se consistente com os objetivos propostos e os valores obtidos do tempo de viagem e da lotação na hora de pico no programa ARENA foram muito similares aos obtidos no TransCAD. / Mestre em Engenharia Civil

Propuesta de rutas alternas a través de la identificación de líneas de deseo para reducir la congestión vehicular, en el área delimitada por los alrededores de los ejes Av. Primavera, Jr. El Polo y Av. La Encalada del distrito de Surco / Proposed alternate routes through the identification of lines of desire to reduce traffic congestion in the area bounded by around Av. Primavera, Jr. The Polo and axes Av. La Encalada of the district of SurcoPiñas Cerron, Franklin Yul, Quinto Garcia, Sibony 26 April 2021 (has links)
La presente tesis tiene por finalidad proponer rutas alternas a través de la identificación de líneas de deseo en el área delimitada por los alrededores de los ejes Av. Primavera, Jr. El Polo y Av. La Encalada, debido a la alta congestión vehicular que se observa en horas pico, identificadas a través de los aforos vehiculares realizados. En primer lugar, se zonifica el área de estudio según su uso de suelo, la delimitación consta de 11 zonas, siendo 6 microzonas y 5 macrozonas. Seguido del aforo vehicular en 5 puntos estratégicos dentro del área en estudio donde existe ingreso de mayor flujo vehicular a la zona. Con la data obtenida en campo se permite cuantificar el número total de encuestas a realizar en cada uno de los 5 puntos de aforo con y se elabora una matriz O-D que es determinante para identificar las líneas de deseo, estas líneas ayuda a identificar los tipos de viaje, tales son los viajes intrazonales, interzonales, viajes de paso y externos. Por lo que, el estudio se centra en los viajes de paso. Estos son aquellos que no necesitan pasar por el área de estudio para llegar a su destino; las encuestas se destinan para cada tipo de vehículo que circula por la zona y también para los peatones. Una vez obtenida la cantidad de encuestas, se plantea el modelo de encuesta a realizar con el objetivo de tener los motivos y los modos de viaje realizados por los usuarios de la vía. Luego, se procede a realizar los trabajos en gabinete, donde se modela en el Software TransCad toda la red vial a escala y se reconoce todos los accesos y salidas de la zona. Al identificar en el software TransCad la línea de deseo con mayor demanda, se plantea el modelo ideal donde se logra desviar los viajes de paso. Los desvíos propuestos son el giro hacia la izquierda en la Av. Angamos hacia la Av. Velazco Astete con salida a la vía de Evitamiento, para los viajes de la zona XX hacia la zona ZZ. Y el cierre del giro en U en la Av. Primavera entre la Av. Encalada y el Jr. El Polo. Finalmente, a través del modelo gravitacional se pudo evaluar condiciones futuras, calibrando los parámetros. Así, se obtiene la generación y atracción de viajes para el año horizonte de planificación en cada una de las zonas definidas. / This thesis aims to propose detours through the identification of lines of desire in the area demarcated by the vicinity of the axes Av. Primavera, Jr. The Polo and Av. The Encalada, due to the high congestion that is observed in peak times that according to the analysis that through the vehicular capacities could be identified. First, the area of study is zoned according to its use of soil, the delimitation consists of 11 zones, being 6 microzones and 5 superzones. Followed by vehicular capacity in the 4 strategic points established where there is entry of greater vehicular flow to the area. With the data obtained in field allows us to quantify the total number of surveys to be carried out at each gauging point and elaborates a matrix O-D that is determinant for the identification and the lines of desire, these lines will not help to identify Ar the types of travel so we will focus on passing trips, these are those who do not need to pass through the study area to reach their destination; The surveys are destined for every type of vehicle that circulates in the area and also for pedestrians. Once the number of surveys has been obtained, the model of the survey to be carried out with the objective of having the reasons and the modes of travel made by the users of the track is raised. Then, work is done in the cabinet, which will model in the Software TransCad the entire road network to scale and recognize all access and exits of the area. The TRANSCAD will identify the line of desire with the highest demand, and the ideal model where it manages to divert the passing of passages. The possible deviations proposed will be the left turn in Av. Angamos towards Av. Velazco Astete with Exit to the bypass, for trips from the XX zone to the ZZ area. And the closing of the U-turn on Av. Primavera between Av. Encalada and Jr. The pole. Finally, through the gravitational model you can evaluate future conditions, calibrating the parameters. And get the generation and attraction of travel for the year horizon planning in each of the defined areas. / Tesis
