Mobilidade urbana sustentável e o caso de Curitiba / Sustainable urban mobility and the case of Curitiba

Hellem de Freitas Miranda 13 October 2010 (has links)
O atual modelo de planejamento dos transportes é constantemente confrontado com novos ideais associados à mobilidade sustentável. Assim, inúmeros pesquisadores debruçam-se em busca de indicadores e índices capazes de avaliar e monitorar o desempenho de políticas públicas relacionadas ao tema. Dessa forma foi desenvolvido o Índice de Mobilidade Urbana Sustentável (IMUS), uma ferramenta pautada nos preceitos da mobilidade sustentável com a proposta de tornar-se um apoio à gestão municipal. Por ser um método recente, sua aplicação ainda é limitada. Assim, o objetivo deste estudo concentra-se em realizar o cálculo do índice na cidade de Curitiba, muito conhecida por suas soluções urbanas que associam o planejamento dos transportes ao uso do solo. A aplicação do método na cidade fundamentou-se não apenas em obter o simples score relacionado ao desempenho das condições da mobilidade local, mas também possibilitaram avaliar o próprio método. O valor resultante alcançado foi correspondente a 0,747, confirmando Curitiba como uma cidade com características bastante positivas quanto às políticas urbanas voltadas à mobilidade. Por outro lado, foram identificadas algumas deficiências, especialmente quanto aos modos não motorizados de transporte. O cálculo do IMUS permitiu encontrar também indicadores que não foram capazes de identificar aspectos reconhecidamente favoráveis da cidade, demonstrando que possivelmente esses apresentem problemas de avaliação ou normalização de valores. A aplicação do método também se mostrou eficiente para promover uma avaliação intraurbana entre as diversas regiões da cidade. Nesse aspecto Curitiba demonstrou um saudável equilíbrio, sem apresentar grandes disparidades quanto suas políticas locais. Tal característica mostra-se bastante favorável para identificar Curitiba como um benchmarking da mobilidade sustentável. Finalmente o método foi testado como uma ferramenta de comparação entre cidades distintas, demonstrando também ser eficiente, desde que se mantenha uma estrutura de cálculo compatível entre as cidades que se deseja comparar. / The current transportation planning approach is constantly confronted with new values derived from the concept of sustainable mobility. As a consequence, several researchers have devoted time and effort in the search of indicators and indexes capable of evaluating and monitoring the performance of urban policies related to the theme. The Sustainable Urban Mobility Index (I_SUM) was one of them. It is a decision support tool developed to help municipal administrations in the planning and management of sustainable mobility. As it is a recent method, its application is still limited to just a few cases. The objective of this study is to conduct an application of the index in Curitiba, which is a well-known city due to the quality of its urban planning solutions that associate transport planning to land use. The application of the method in the city was motivated not only by the possibility of having a score showing the performance of the city regarding sustainable mobility, but also by the opportunity of evaluating the method itself. The overall resulting value was 0.747, what confirms that Curitiba has very positive characteristics and effective urban policies regarding sustainable mobility. Conversely, some deficiencies were identified, especially concerning non-motorized transport modes. The I_SUM calculation also allowed the identification of indicators that were not able to identify aspects that are good to the city. That may suggest problems in the assessment or normalization procedures of the index. The method application was also efficient for the evaluation of city subdivisions. Curitiba also performed well in that intra-urban evaluation, with a positive equilibrium of the values throughout the city. It may be an indication that the city policies are homogeneously applied in the entire urban area, what certainly contributes to characterize Curitiba as a benchmark of urban mobility. Finally, when used to compare distinct cities, the method was also efficient. In that case, the calculation was compatible with a structure adjusted to simultaneously represent the compared cities.

A verticalização na cidade de São José dos Campos-SP, sob a ótica do adensamento : um estudo de caso

Isaac da Costa Carvalho Netto 21 November 2012 (has links)
A verticalização dos edifícios gera adensamento populacional, reduz os espaços livres para edificação, promove o sombreamento de áreas e edificações vizinhas, canaliza o vento o que leva à alteração do microclima, aumenta o gasto de energia e impermeabilização do solo, todos estes fatores influem na qualidade do meio ambiente e da vida das pessoas. O objetivo proposto neste estudo foi compreender o processo de ocupação de espaço que ocorreu no Jardim Aquarius da cidade de São José dos Campos, SP, em função do aumento do adensamento populacional provocado pela crescente verticalização, influindo, principalmente na qualidade de vida e no meio ambiente. Os Resultados mostraram que o Jardim Aquarius, apresenta enorme verticalização, como bem ilustra o Jardim Aquarius o que resulta em adensamento populacional e, consequentemente, em prejuízos para a mobilidade urbana de uma forma geral. As grandes cidades funcionam com eficácia quando em seus Planos Diretores estão previstos confortáveis e confiáveis sistemas de transporte de massa. Conclui-se que um replanejamento para o Jardim Aquarius pode resultar em melhora da qualidade ambiental, trazendo bem-estar para a população em geral. / The verticalization of buildings begets densification, reduces clearances for edification, promotes the shading areas and neighboring buildings, pipelines the wind which leads to alteration of microclimate, increases energy expenditure and soil sealing, all these factors influence the quality of the environment and peoples lives. The objective of this study was to understand the process of occupation of space that has been occurring in Aquarius in the city of São José dos Campos, SP, as a function of increased densification caused by increasing verticalization, working mainly on the quality of life and the environment. The results showed that the municipality of São José dos Campos, offers enormous vertical integration, as well illustrates the Aquarius Garden resulting in densification and, consequently, in losses to urban mobility in General. The big cities work effectively when their Plans are provided for comfortable and reliable mass transit systems. It is concluded that a redesign of the garden Aquarius can result in improved environmental quality, bringing well-being to the population in General.

[pt] IMPACTOS DA IMPLANTAÇÃO DO TELEFÉRICO COMO SISTEMA DE TRANSPORTE NAS FAVELAS: O CASO DO COMPLEXO DO ALEMÃO / [en] IMPACTS OF THE DEPLOYMENT OF CABLE CAR AS TRANSPORT IN SLUMS: THE CASE OF THE COMPLEXO DO ALEMÃO

29 October 2021 (has links)
[pt] Esta pesquisa disserta sobre as soluções de mobilidade urbana em favelas de encostas como parte integrante do planejamento urbano, tendo como foco a implantação do sistema de transporte teleférico e como estudo de caso, o teleférico do Complexo do Alemão. Inicialmente é apresentado um panorama histórico das intervenções do poder público nas favelas do Rio de Janeiro e como se desenvolveu a mobilidade urbana nessas áreas. Em seguida, é exposto o problema da mobilidade nas favelas e a implantação de equipamentos alternativos de transportes. Os Projetos de implantação do teleférico Metrocable em Medellín, o teleférico de San Augustín em Caracas, o teleférico do morro da Providência e o projeto para o teleférico da favela da Rocinha são expostos como exemplos desse sistema. No Estudo de caso, foram analisados os impactos da implantação do teleférico no Complexo do Alemão, sua eficiência e principalmente, os custos de execução, operação e os custos sociais. Considera-se que o impacto estudado é moldado por análises contextuais, avaliações empíricas de visitas ao local, entrevistas com os moradores e usuários do sistema em questão, conteúdos bibliográficos e análise de indicadores. / [en] This research is on urban mobility solutions in favelas (slums) on hills as an integral part of urban planning. With a focus on the implementation of cable cars as transport systems, this research examines the cable car of the Complexo do Alemão as a case study which is located on the north side of the city of Rio de Janeiro. In Chapter 1, the research outlines the problem of poverty and absence of urban planning in Brazilian cities, which has intensified since the 1950s because of the rapid influx of migrants in search for work in the great economic city centers. Currently in Rio de Janeiro, 22 per cent of the population lives in favelas. The population of the favelas grew disproportionally in the last two decades, four times more than the population of the officially recognized areas of the city. The problem of housing in the favelization process of the city is aggravated by poor sanitation, violent conflicts, problems with security and safety, a lack of public services, poor access, precarious urban mobility, irregular services like illegal connections to electricity, among other problems. Additionally, there is the overarching problem of urban mobility. Spatial segregation makes it difficult for low-income populations to move from one place to another and is mainly due to the historical selection of occupations in isolated and peripheral areas of the city. The problem of mobility is further aggravated by underdeveloped transitional areas between the rural and urban parts of the city especially when, like in the case of this research, those populations occupy areas with steep hills. The chapter continues by tracing a history of public policies affecting the favelas of Rio de Janeiro, from the first removal of tenement houses in the city center in the nineteenth century, to the developmental policies of today. The chapter follows the formation of the first favelas with an occupation organized by the people who were removed from tenement houses and who needed to live near the economic city centers, the eventual expansion to other areas, the first removal policies for temporary housing and subsequently a more rigid posture of the state in regard to favelas. The 1960s and 1970s were periods marked by the removal and political denial of favelas, it was only in the 1980s that the state began to provide public policies to improve favelas. Thus, there has been a gradual acceptance of these occupations in the landscape of the city. Beyond the social problems aforementioned, Chapter 2 points more specifically to the problems of mobility in favelas on hills because of high building density, risks of landslides and precarious road access. In Rio de Janeiro, the state started to intervene in regard to the issue of mobility in favelas during the first term of Leonel Brizola (1983-1987), with the construction of the Inclined Plane in the Pavão Pavãozinho favela. But it was not until the Favela Bairro program that mobility initiatives were executed on a much wider scale, the program initiated walkways and improved stairs which greatly increased accessibility and the flow of traffic on road networks. With an urbanization policy for favelas in motion, other urban mobility transport systems were established, like the inclined plane on the Hill of Santa Marta in 2008 and the elevator of Cantagalo in 2010. While these transport systems assert the presence of the state in marginal communities, the daily transportation of the residents are mainly local options like vans and motorcycle taxis which continue to play a fundamental role and also contribute to the local economy. This generates income for residents because many of the people working with this type of transport also live in the favelas. The chapter then describes cable car technology and looks at specific examples of cable cars built or planning to be built in the favelas of Latin America. The lines of Medellin are used as an example because they inspired so many others like San Agustín in Caracas, Complexo do Alemão in Rio de Janeiro, Providencia in Rio de Janeiro and the cable car project of Rocinha in Rio de Janeiro. The city of Medellin for many years suffered from violence generated by drug trafficking and came to be known in the early 90s as one of the most violent cities in the world. The high murder rate and violence receded after a series of investments that occurred in the city, mainly investments towards urbanization, education and security. The urban planning of Medellin was based on major public interventions through specific projects in the poorest sectors of the city. Initially structured around the cable cars, called Metrocables, and spatially articulated with other projects extended to formal sectors of the city, known as Urban Integral Projects (Proyectos Urbanos Integrales-PUIs), the aim of these initiatives was to connect various urban spaces. One of the characteristics of these projects was the emphasis on aesthetics as an engine for social change. This aesthetic quality to the new cable cars resulted in an increase of residents self-esteem but was also criticized for its stark contrast with poor local reality. In 2004, the Line K of the cable car was constructed in Comunas 1 and 2, and initiated an urban planning of the city based on the theory of Social Urbanism, with several projects aimed at improving infrastructure and education in favelas. In 2010, Line K was supplemented by a transfer to the Line L, which goes to the Arvi Park, an ecological park created on the border of a green area to Comuna 1, stimulating tourism. There is also Line J which meets Comunas 7 and 13, inaugurated in 2008. Medellín has become a model for other cities to adopt the cable car system for transportation in favelas. One example was the cable car of San Agustín in Caracas, designed as an important integrator between the favela and the rest of the city. In January 2010, the system started was connected to the subway. In contrast to Medellin, the Metrocable system in Caracas is characterized with large stations that integrate cultural facilities, sports arenas, and shopping centers together in one convenient location. The estimated daily demand during the planning stages of the project was 15 thousand passengers. Approximately 40,000 people live in San Augustin which means that the demand estimate would amount to 37.5 per cent of the residents. The data in 2012 showed that only 4,500 passengers use the system daily, about three times less than expected, showing that the cable car, which cost 318 million dollars, is being underutilized. In Rio de Janeiro, in the favela Morro da Providência, there is a cable car built and because the favela is considered the first favela in Rio, current projects by the municipal government show that there is interest in promoting tourism and to integrate it with the dynamics of cultural and historical revitalization of the port area and the cable car is the vehicle proposed for this purpose. However, the Hill of Providence (Morro da Providência) is suffering from forced evictions, mainly due to the Morar Carioca project, an urban program of the city government. These interventions have not been discussed with the residents and involve the demolition of nearly half of the residences. The idea is to replace the residences with a historical and cultural center in the favela. According to the city administration, about 42 houses block, in the context of urban landscape, the view of the chapel located at the highest point of the hill and thus those 42 houses would have to be removed. Although the construction of the cable car has also caused the removal of a few houses, its implementation is linked more with tourism in the favela. Various resident led protests organized with activists and supported by critical news sources released in Brazil and abroad, put the Hill of Providence in the spotlight as an example of the negative impact of mega-events on the poor. Consequently, after the injunction obtained in a lawsuit, the projects in the community are at a standstill and the houses that were scheduled to be removed remain standing. In Rocinha, the PAC 2 (Accelerating Growth Program is a federal program that has as the main objective the development of the country through the planning and execution of large urban infrastructure, works in the transportation sector and the energy sector) provides for the cable car installation, an elevator, escalators, and other mobility infrastructure. This project is very controversial because the cable car project has an estimated budget of 700 million reais, an amount that would consume approximately 44 per cent of the total amount available for the PAC 2. Most debate is on the residents priorities, which if considered would require that the funds be applied to the sanitation of the favela, which the current project does not guarantee. In the project under study, the cable car will connect to the future subway station of Line 4 in São Conrado to the top of the favela and have 6 stations distributed in two lines, 2,500 meters long. This would be the third cable car built in the favelas of the city, reflecting a state trend to adopt this transportation method in favelas. It seems that cable cars are more than a modal of mass transport, but also as a way to enter favelas as a new tourist attraction of the city. In Chapter 3, the case study is presented about the cable car of Complexo do Alemão, an integral part of PAC. The cable car was built with 3.4 km in length, 152 cabins half of which are in regular operation, while the other half is parked. The system has six stations and the capacity to carry 30,000 passengers daily. The path between the first transfer station with the train, the Bonsucesso Station, and the last stop, the Palmeiras Station, is traversed in about 20 minutes. Using other means of transport, the time to travel the distance between these two places is about 40 minutes. The six stations are located on the tops of hills that form the intricacies of the favelas and therefore, many residents complain about the accessibility of the system. For those who live far away and do not see advantage in climbing the hill to use the system, it is more common to use van or motorcycle taxis to move around. This is the main reason that the cable car is underused even though residents are entitled to two free trips per day. According to the Supervia, which operates the system, the daily movement of people is about 10,000 to 11,000 people, but, as we reported, the equipment has been design for a capacity of 30,000 passengers per day. The construction of the cable car cost the government R$ 210 million, equivalent to 22.35 per cent of the total PAC work in Complexo do Alemão, and the operating cost is about 50.1 million reais a year. What we can conclude is that the cable car has a relatively high operating cost for low use by residents, and it is also expensive to build. The high investment in the cable car is not justified when there are still major problems to be solved in favelas. One of the main complaints made by residents is the lack of investments in priority areas, such as basic sanitation. As part of this research a survey was given to 50 residents. When asked if the resources used to cable car execution, being very high, could be implemented in other areas, 74 per cent said yes. Among the responses on areas where resources should be invested, they pointed mainly to sanitation, health and education. Some health problems in the favelas worsened while tourism has increased with the use of the cable car. Also according to the data from the Supervia, the percentage of passengers with gratuities, i.e. registered residents using the cable car during the week is 75 per cent and the percentage of those who paid the fare, mostly tourists, is 25 per cent. On weekends, the number of visitors almost doubled: 54 per cent of gratuities and 46 per cent of tourists. The cable car has always had a tourist appeal due to its comfort and excitement by offering the experience of getting a suspended adventure of great heights with a privileged view of the favela landscape. This also happens with the cable car of the Complexo do Alemão, but in another context, within a patrimonialization effort of those spaces. The research makes clear that even with the difficulties within a space precariously built, mobility solutions that were initially created by the residents are still the most used, for example, the alternative transport system like vans and motorcycle taxis. To establish that the cable car is the solution for urban mobility on slopes of slums is quite questionable, as each case requires a specific and detailed study. In the case of the Complexo do Alemão, for example, both positive and negative factors were found. On the one hand the cable car considerably reduced the Bonsucesso travel time to some community points and provided connection with the train, on the other, the number of users contained does not justify its high cost. It is also clear that the general population in favelas want more primary rights met like access to health care, the installation of sewer systems, and competent schools as their priority.

Barns perspektiv på framtidens resor med autonom buss / Children’s perspective on future travels by autonomous bus

Larsson, Kristina January 2021 (has links)
Barns mobilitet och möjlighet att på egen hand ta sig runt i staden har minskat och begränsas idag i stor utsträckning av otrygga trafiksituationer. I och med sin begränsade oberoende mobilitet exkluderas barn från stadsrummet och dess faciliteter. Oberoende mobilitet kan relateras till flera dimensioner av barns sociala, fysiska, psykiska och kognitiva välmående. Syftet med studien är att undersöka om och på vilket sätt autonoma bussar kan bidra till barns oberoende mobilitet och med hjälp av barns upplevelser och erfarenheter bidra med insikter i detta inför införandet av autonoma bussar i städer och kollektivtrafiksystem. För att göra det besvaras frågeställningarna “Hur kan autonoma bussar i transportsystemet bidra till barns oberoende mobilitet?” och “Vilka förutsättningar är nödvändiga för att autonoma bussar ska bidra till barns oberoende mobilitet?”. Undersökningen utgår från ett fall av införande av autonoma bussar i stadsmiljö och för att besvara frågeställningarna genomfördes med elever på en grundskola fokusgrupper med syfte att inhämta deltagarnas upplevelser och erfarenheter. Resultatet tyder på att införandet av autonoma bussar i ett urbant område kan bidra till barns oberoende mobilitet på flera sätt och att bussarna har vissa egenskaper som gör att de kan anpassas till barns förutsättningar. Insikter från studien kan bidra till en förståelse för hur, från barns eget perspektiv, oberoende mobilitet kan gynnas av autonoma bussar i kollektivtrafiken, samt hur tjänsten behöver utvecklas för att anpassas till denna användargrupp när autonoma bussar i större utsträckning ska implementeras i staden. / Children's mobility and the opportunity to get around the city on their own has decreased and is today limited to a large extent by unsafe traffic situations. Due to their limited independent mobility, children are excluded from the urban space and its facilities. Independent mobility can be related to several dimensions of children's social, physical, mental and cognitive wellbeing. The purpose of the study is to investigate if and in what way autonomous buses can contribute to children's independent mobility and, using children's experiences, provide insights into this before the introduction of autonomous buses in cities and public transport systems. To do so, the two research questions "How can autonomous buses in the transport system contribute to children's independent mobility?"and "What prerequisites are necessary for autonomous buses to contribute to children's independent mobility?" are answered. The survey is based on a case of introduction of autonomous buses in urban environments and to answer the questions three focus groups with students in a primary school were conducted with the aim of gaining the participants' experiences. The results indicate that the introduction of autonomous buses in an urban area can contribute to children's independent mobility in several ways and that the buses have certain characteristics that enable them to be adapted to children's conditions. Insights from the study can contribute to an understanding of in what way, from children's own perspective, independent mobility can benefit from autonomous buses in public transport, and how the service needs to be developed to adapt to this user group when autonomous buses are to be implemented to a greater extent in the city.

Relações entre características espaciais de cidades e a resiliência na mobilidade urbana /

Matiolli, João Antonio Camargo January 2020 (has links)
Orientador: Gustavo Garcia Manzato / Resumo: O trabalho apresentado teve como objetivo principal avaliar as relações entre características espaciais das cidades e a resiliência em relação à mobilidade urbana, considerando os diferentes portes de municípios, em um estudo aplicado para o estado de São Paulo. Para atingir tal objetivo, foi proposto o desenvolvimento de um método de avaliação da resiliência na mobilidade urbana considerando viagens não motorizadas (caminhada e bicicleta), utilizando como inovação a Grade Estatística do IBGE. Em geral, para o modo a pé foi observado que cerca de 46% dos municípios analisados seriam totalmente resilientes, sendo que esta proporção é composta pelos munícipios de menor porte. Já os municípios que apresentaram uma baixa resiliência compreendem aproximadamente 11% do total de municípios e são caracterizados por aqueles de maior porte e mais populosos do estado. Para o modo bicicleta a situação é diferente, nota-se que apenas os municípios de São Paulo e Ilhabela apresentam baixa resiliência. Além disso, é observado que 91% dos municípios são totalmente resilientes em relação a esse modo de deslocamento. A partir dos resultados do método, buscou-se relacionar essa resiliência com métricas espaciais das cidades por meio de índices de forma urbana, a saber: Densidade, Concentração, Agrupamento e Centralidade. Dessa maneira, concluiu-se que a Densidade Domiciliar é o parâmetro que mais se destaca, uma vez que quanto maior o porte do município, maior foi o valor observado para essa mé...

To achieve this objective, we proposed the development of a method for assessing the resilience in urban mobility considering non-motorized trips (walking and cycling), using the Statistical Grid of the Brazilian Institute of Geography and Statistics as an innovation. In general, for walking, we observed that around 46% of the municipalities would be totally resilient, and this proportion corresponds to the smaller municipalities. On the other hand, the municipalities that show a lower resilience comprise approximately 11% of the total and are characterized by the largest and most populous municipalities in the state. For cycling the situation is different. We noted that only the municipalities of São Paulo and Ilhabela present a low resilience rate. In addition, we observed that 91% of the municipalities are totally resilient to this travel mode. In turn, we sought to establish a relationship between this resilience with spatial metrics of the cities through urban form indexes: Density, Concentration, Clustering and Centrality. Thus, we concluded that the household density is the parameter that stands out the most, since the larger the size of the municipality, the higher the value for this metric. For the other metrics (Concentration, Cl... (Complete abstract click electronic access below) / Mestre

Mobilités urbaines et données en ligne pour l'étude des maladies vectorielles à Delhi (Inde) et Bangkok (Thaïlande) / Urban mobility and online data for the study of vector borne diseases in Delhi (India) and Bangkok (Thailand)

Cebeillac, Alexandre 17 October 2018 (has links)
Des maladies vectorielles émergentes, comme la dengue, aggravent les crises de santé publique dans les mégapoles asiatiques de Bangkok (Thaïlande) et Delhi (Inde). Les liens entre les moustiques et l’environnement urbain ont été documentés mais la compréhension des mobilités humaines, en tant qu’élément primordial de diffusion des virus, reste un objet de recherche d'intérêt général à développer.En l'absence de données institutionnelles adaptées, notre recherche s'est d'abord orientée vers des enquêtes de terrain, puis sur la collecte, le traitement, la comparaison et la critique de données provenant d'acteurs majeurs d'Internet (Twitter, Facebook, Google, Microsoft). Leur potentiel varie selon les zones géographiques, mais elles permettent d'éclairer l'organisation et la structure des villes étudiées. De plus, elles font ressortir les temporalités et les interactions intra-urbaines. Toutefois, il semble encore difficilement envisageable de se passer de connaissances acquises in situ. En utilisant le concept d'espace d'activité, nous proposons une méthode permettant de produire des agendas individuels synthétiques, générés à partir de données Twitter et d'enquêtes de terrains. Il s'agit là d'une première étape dans l'élaboration d'un modèle de mobilité individu-centré à base d'agents. / Emerging vector-borne diseases such as dengue intensify public health crises in the Asian megacities of Bangkok (Thailand) and Delhi (India). The links between mosquitoes and the urban environment are well documented, but our understanding of human movement, as a key element of virus spreading, has yet to be fully explored as a research subject. Given the paucity in adequate or available institutional data, our research first focused on field surveys, and then on the collection, comparison and critique of data collected from major Internet platforms (Twitter, Facebook, Google, Microsoft). Their potential varies from one geographical area to another, still they shed light on the organization and structure of the studied cities. Moreover, they highlight intra-urban interactions and timeframes. However, carrying out such studies without knowledge acquired from the field seems unadapted. Using the concept of activity space, we propose a method to produce individual synthetic agendas, generated from Twitter data and field surveys. This is a first step in the development of an agent-based model of individual mobility.

Propuesta de mejoramiento de la movilidad urbana en el distrito de san miguel a través de la implementación de estaciones de bicicletas públicas / Proposal to improve urban mobility in the district of san miguel through the implementation of public bicycle stations

Chang Ramírez, Giancarlo 23 December 2020 (has links)
La presente investigación aborda la problemática de la movilidad urbana en el distrito de San Miguel, y propone como alternativa sustentable de transporte un sistema estaciones de bicicletas públicas. De esta manera, se buscaron las localizaciones óptimas de estaciones a través de un estudio de demanda y análisis de cobertura utilizando modelos de localización-asignación. La demanda fue estimada a través del método de generación de viajes del “Trip Generation Manual” utilizando factores de distribución horaria del NCHRP 365, los cuales fueron ajustados por la metodología de uso suelo mixto propuesta por la empresa Fehr & Peers. Paralelamente, se elaboró un modelo SIG con la información geográfica del distrito; sobre el cual se plantearon los modelos de localización-asignación de máxima cobertura y mínima impedancia, considerando los escenarios de implementación de 10, 25, 50 y 100 estaciones para cada uno. Adicionalmente, se realizaron encuestas para identificar el perfil de usuarios ciclistas en el distrito de San Miguel y su interés por un sistema de bicicletas públicas; cuyos resultados permiten validar el sistema propuesto. Finalmente, se analizaron las características de cada escenario, y se determinó que la propuesta de 100 estaciones con el modelo de máxima cobertura otorga mayor accesibilidad y mejora la movilidad urbana en términos de cobertura a nivel distrital en un 77% y promedio sectorial en 66%. / This research addresses the problem of urban mobility in the district of San Miguel, and proposes a system of public bicycle stations as a sustainable transport alternative. In this way, optimal station locations were searched through a demand study and coverage analysis using location-allocation models. The demand was estimated through the trip generation method of the “Trip Generation Manual” using hourly distribution factors from NCHRP 365, which were adjusted by the mixed land use methodology proposed by the Fehr & Peers company. At the same time, a GIS model was developed with the geographic information of the district; on which the maximum coverage and minimum impedance location-assignment models were proposed, considering the implementation scenarios of 10, 25, 50 and 100 stations for each one. Additionally, surveys were conducted to identify the profile of cycling users in the San Miguel district and their interest in a public bicycle system; which results allow to validate the proposed system. Finally, the characteristics of each scenario were analyzed, and it was determined that the proposal of 100 stations with the maximum coverage model provides greater accessibility and improves urban mobility in terms of coverage at the district level by 77% and the sectorial average by 66%. / Tesis

En el presente trabajo de investigación se analiza y estima el impacto económico y social del servicio de transporte público masivo El Metropolitano que utiliza como infraestructura el Corredor Segregado de Alta Capacidad – Cosac I. Este sistema se ha constituido como el principal medio de transporte de la ciudad de Lima por atributos como: la formalidad de su servicio, la infraestructura que ofrece, su modernidad, la rapidez, entre otros aspectos que se desarrollan en las siguientes páginas. El documento está dividido en ocho capítulos. El primero está referido a los fundamentos teóricos de la investigación, el segundo contiene una breve descripción de la realidad del transporte urbano de pasajeros y de los sistemas de transporte que existen en Lima Metropolitana, la oferta actual y en este marco, se contextualiza la problemática detectada en cuanto a la informalidad, falta de regulación, baja calidad del servicio e infraestructura para la movilidad urbana en la ciudad. El tercer capítulo desarrolla la finalidad, los objetivos, justificación y alcance de la investigación. El cuarto capítulo aborda los supuestos, la hipótesis, variables e indicadores que pretendemos comprobar. Seguidamente, en el quinto capítulo se describe la metodología utilizada para realizar esta investigación y, en el sexto capítulo se presentan los resultados obtenidos de las encuestas, así como su respectiva interpretación. Por último, en el capítulo séptimo se exponen las conclusiones de la investigación realizada y en el octavo, se plasman las recomendaciones que corresponden, que esperamos sean consideradas como aporte a la gestión pública en materia de transporte. / This document of investigation measured and analyzed the economic and social impact of mass public transport service so-called “El Metropolitano” which uses as infrastructure the High Capacity Segregated Roadway  – COSAC I.
