This thesis critically examines the role of indigeneity in urban policies and planning in a context of constitutional changes that have taken place in Bolivia and Ecuador in the recent decade. It departs from previous academic and policy research which mainly studied indigenous rights in rural areas and focused on urban indigenous peoples as outlawed, excluded, or insurgent subjects. Instead, it conceptualises the translation of indigenous rights into urban policies as a complex process in which a multiplicity of social actors – including government officials and urban indigenous groups – are involved. Drawing on the practice-centric literature on urban policy and planning, it recognises that the work of government officials is influenced by multiple factors such as constitutional texts as well as their personal views, interest group demands, and the wider structural and political environment surrounding them. Government attempts to translate indigenous rights are contrasted to urban indigenous peoples’ own understandings of indigeneity and associated interests and demands. In addition, this thesis uses an asset accumulation framework as well as the concept of tactics to identify how urban indigenous peoples address and negotiate their interests and demands and try to influence decision-making processes from the bottom-up. The thesis relies on La Paz (Bolivia) and Quito (Ecuador) as ‘illustrative cases’ to study the role of indigeneity in urban policies. As both La Paz and Quito represent capital cities, it was possible to approach government officials operating at multiple scales – international, national and local – as well as ordinary urban indigenous residents. Methodologically, the thesis employs a qualitative, case study comparison and draws on information derived from semi-structured interviews, document analysis, participant observation and participatory focus groups conducted during eleven months of fieldwork. In terms of comparison, this thesis makes use of a variation-finding approach. By explaining variations between the cases through focusing on the unique processes and factors that shaped the translation of indigenous rights within each city, it intends to offer a more nuanced and context-responsive approach for studying urban indigeneity and addressing indigenous rights in cities. A central finding of this thesis is that the incorporation of indigeneity into urban policies and indigenous people’s own practices to fulfil their specific demands were characterised by a set of conflicting realities: First, for government officials the translation of indigenous rights into urban policies sometimes clashed with other priorities – such as addressing universal rights and interests of non-indigenous pressure groups – or with their own views of the city as a ‘white’, ‘western’, and ‘modern’ places. Second, urban indigenous peoples articulated multiple and contradictory identities. They mainly did this by voicing specific demands for land – an important asset which they associated with the preservation of a communal and traditional lifestyle but also with aspirations to lead a modern and capitalist life in the city. Third, the findings reveal that indigenous peoples – particularly their community leaders – had to enter in negotiations with governments to access different assets such as land, housing, or education. In these processes leaders manoeuvred between different worlds. They had to conform to political agendas and – particularly in the case of Bolivia – to official spatialized understandings of identity and rights which often conflicted with their own sense of being indigenous in the city.

[ES] Esta tesis doctoral tiene por objetivo general expandir la escultura quiteña (de la ciudad de Quito), normalmente supeditada a convencionalismos sociales ampliamente difundidos y al conservadurismo académico local, ambos mayormente centrados en la noción de monumento. Para ello se ha desarrollado un proceso investigativo y creativo en bucle, definido en los objetivos específicos programados, a partir de los fundamentos teóricos, históricos, técnicos y tecnológicos de la escultura cinética, incluyendo la mención de sus principales practicantes, extranjeros y locales; así como de los conceptos de mediación, juego y público, y los recursos relacionados a estos, aplicados y aplicables a la escultura. De allí se ha establecido un método creativo para el diseño de las obras cinéticas propuestas. Método que se alimenta tanto del campo específico del arte como de otras disciplinas estudiadas; y que posibilita la creación de obras escultóricas cinéticas en acero estructural, sistematizando y documentando su proceso creativo. Finalmente, se ha evaluado la interactividad generada entre las esculturas realizadas y el público de las mismas. Con todo ello, cual objetivo superior, esta investigación-creación aspira a contribuir al campo del arte local proporcionando nuevas perspectivas y prácticas escultóricas mediante la inserción, cual intervención social en la esfera académica quiteña, de la escultura cinética corporal y semánticamente interactiva. / [CA] Aquesta tesi doctoral té per objectiu general expandir l'escultura quiteña, normalment supeditada a convencionalismes socials ámpliament difosos i al conservadorisme acadèmic local, tots dos majorment centrats en la noció de monument.

For this, a looping investigative and creative process has been developed, defined in the specific programmed objectives, based on the theoretical, historical, technical and technological foundations of kinetic sculpture, including the mention of its main practitioners, foreign and local; as well as the concepts of mediation, game and public, and the resources related to these, applied and applicable to sculpture. From there, a creative method has been established for the design of the proposed kinetic artworks. Method that feeds both on the specific field of art and on other studied disciplines; and that enables the creation of kinetic sculptural works in structural steel, systematizing and documenting their creative process. Finally, the interactivity generated between the sculptures and their public has been evaluated. With all this, as a higher objective, this research-creation aspires to contribute to the field of local art by providing new perspectives and sculptural practices through the insertion, as a social intervention in the Quito academic sphere, of kinetic and semantically interactive corporal sculpture. / García Moreno, MF.

La presente investigación analiza el papel del segundo proceso por sodomía del doctor Manuel Barros de San Millán (1532- ¿?), presidente de la Audiencia de Quito a finales del siglo XVI. Su controvertida carrera en Indias permitirá entender cómo las enemistades acumuladas, entre 1560 y 1590, jugaron un papel determinante en esta acusación. A pesar de tener una primera acusación en 1578, se entiende como determinante la segunda debido a su impacto político. Además, se examina el discurso contra prácticas sexuales prohibidas por la Iglesia y el Estado, como la sodomía, y la respuesta social a estos actos. Asimismo, se estudia cómo repercute el nefando crimen en el las relaciones clientelares de la España del siglo XVI. De manera que, el segundo proceso por sodomía contra el Doctor Barros tuvo un objetivo político, eliminarlo de la carrera en Indias.

Latin American cities are challenged by the effects of population growth and insufficient infrastructure. As a consequent, Informal Car Share (ICS) is increasingly filling the gap as a transportation choice for underserved populations. ICS is the use of private vehicles to provide transportation for a fare that is neither taxed nor regulated by any type of government. Although this practice contributes significantly to development and economic growth, it is often stigmatized as unreliable and inconsistent, and little is known about it. This research expands existing definitions of ICS, using cases from Quito, Ecuador, a mountain city located in the Andes region in South America. It does so by analyzing Quito's ICS perceived effectiveness and performance from its users and drivers, the disruptions this system faces in the communities in which it operates, and its resiliency to bounce back from those disruptions. Findings suggested that despite its informality, ICS works with fixed stops, schedules, routes and fares. This is similar to formal systems operated by the government. Users and drivers described ICS as reliable and consistent, and they all reported a positive experience with the service. Findings also suggested that Quito's ICS is disrupted by six natural and political disruptions that delay the ICS service for 10 to 40 minutes. However, ICS proved to be adaptable and able to circumvent disruptions to ensure passengers connectivity to the city. Lastly, findings suggested that ICS users and drivers developed eight adaptation strategies to circumvent disruptions. Those strategies have created a system that aligns with features of resilient urban systems from UN-Habitat. Expanding the current understanding of how ICS operates, as well as its resilience capacity, is the first step to understanding better the value these self-organized systems provide to cities. / Doctor of Philosophy / The population in Latin America's cities is increasing and cities have been unable to keep up with the infrastructure demands that growth has created.

This thesis focuses on Secretos entre el Alma y Dios, the autobiography or vida of Catalina de Jesús María Herrera (1717-1795), a nun who belonged to the Dominican Convent of Santa Catalina in Quito, Ecuador. Catalina wrote in a direct and engaging style of her monastic life and spirituality. Her text allows us to better understand the society in which she lived and particularly her relationship with her confessor, fray Tomás del Rosario Corrales, to whom she writes her autobiography. Her numerous visions are classified here as divine, evil and death visions. They draw from traditional hagiographic accounts and provide evidence of how Saint Teresa of Ávila’s Libro de la Vida was read in a colonial context. A close-textual reading of Catalina’s vida, sheds light on her claims to have reached God as the expression of a female voice long suppressed in this patriarchal society. / Graduate

Para isso, o processo artístico e pedagógico da diretora, atriz e professora da Escola de Arte Dramática EAD-USP, Cristiane Paoli Quito, serviu de guia e condutor desta pesquisa. Os sujeitos observados foram os alunos do terceiro ano da Escola de Arte Dramática, Turma 59/EAD-USP. O período estudado foi de agosto a dezembro de 2009. Foram observados e analisados os procedimentos pedagógicos de construção da dramaturgia corporal, utilizadas por essa diretora na montagem da peça teatral O Gato Malhado e a Andorinha Sinhá, adaptada ao teatro pelo dramaturgo e professor da Escola de Arte Dramática (USP), Rogério Toscano, com a colaboração de todo o elenco de atores/estudantes da turma 59/EAD-USP. A montagem da peça, O Gato Malhado e a Andorinha Sinhá, fez parte da aula de Estudos e Práticas de Montagem e foi dirigida por Cristiane Paoli Quito. Mesmo tendo observado e analisado a montagem teatral como um todo, concentrei-me em um foco principal: descrever e analisar o processo pedagógico de construção da dramaturgia corporal na montagem da peça O Gato Malhado e a Andorinha Sinhá de modo a compreender como Cristiane Paoli Quito trabalha, pedagogicamente, a construção da dramaturgia corporal com alunos/atores na criação de um espetáculo. Sendo assim, o trabalho pedagógico de construção das ações físicas com os atores da turma 59 EAD/USP teve maior importância nesta pesquisa, se comparada a outros elementos que envolvem uma montagem teatral (texto, direção, luz, cenário, música, figurino etc.). O trabalho da coreógrafa e bailarina Tarina Quelho também foi analisado, uma vez em que essa fez a parte da preparação corporal dos alunos/atores, através da técnica do BMC... / The main aim of this study is to understand pedagogical procedures of the bodily training of actors. For this, the artistic and pedagogical process of Cristiane Paoli Quito director, actress and teacher at the School of Dramatic Art EAD-USP served as a guide. The third year students of the School of Dramatic Art, Group 59 EAD-USP were the subjects observed. The study took place between August and December 2009. The procedures utilised by this director while putting together the play The Swallow and the Tom Cat : A Love Story were observed and analysed. This literary work by Jorge Amado was adapted to the stage by Rogerio Toscano, teacher and dramatist at the School of Dramatic Art EAD-USP, with the collaboration of the whole cast of actors / students of Group 59. The putting together of the play The Swallow and the Tom Cat: A Love Story was part of a class called Estudos e Praticas de Montagem (Studies and Practices of plays) and was directed by Cristiane Paoli Quito. Even having observed the putting together of the whole play, the study main focus is: describe and analyse the pedagogic construction of the physical dramatisation of the play. This study can be summed up with one main question: how is it that Cristiane Paoli Quito work, pedagogically with the construction of the physical drama with students/actors in the creation of the play? In this way the pedagogical work of the construction of the physical actions of the actors of Group 59 EAD/USP was the most important thing in the study, if compared to the other elements which are involved in putting together a play (text, lights, scenery, music and costumes). The work of the choreographer and ballerina Tarina Quelho was also analysed, as she prepared the students/actors using a technique called BMC (mind body centring). Rogerio Toscano took part as a dramatist, helping Group 59 in reinterpretation of Jorge Amado's original text. He is also extensively quoted in this dissertation

Although, the great challenge founded out is how to keep a constant and efficient production. The alternative proposed by this present work was to study the viability to develop an integrated technology, with reduced costs. The strategy used was the obtaining of the oligomers through enzymatic hydrolysis using chitosanolitic enzymes obtained straight from the fermented broth, eliminating this way the phases involved in the enzymes purification. The two chitosanases producing strains chosen for the work, Paenibacillus chitinolyticus and Paenibacillus ehimensis, were evaluated according to the behavior in the culture medium with simple sugar and in relation to the pH medium variations. The culture medium for the chitosanases induction and production was developed through addition of soluble chitosan as carbon source. The soluble chitosan was obtained using hydrochloric acid solution 0.1 M and afterwards neutralization with NaOH 10 M. The enzymatic complexes were obtained from induction process in culture medium with 0.2% of soluble chitosan. The enzymes production was verified soon after the consumption of the simple sugars by the microorganisms and the maximum chitosanolitic activity obtained in the fermented broth by Paenibacillus chitinolyticus was 249 U.L-1 and by Paenibacillus ehimensis was 495U.L-1. These two enzymatic complexes showed stability when stored at 20?C for about 91 days. The enzymes in the fermented broth by Paenibacillus chitinolyticus, when exposed at temperature of 55?C and pH 6.0, where the activity is maximum, showed 50% lost of activity after 3 hours Meanwhile, for the complex produced by Paenibacillus ehimensis, after 6 days of exposure, it was detected 100% of the activity. The chito-oligosaccharides obtained by the hydrolysis of a 1% chitosan solution, using the enzymatic complex produced by Paenibacillus chitinolyticus showed larger quantity after 9 hours hydrolysis and using the complex produced by Paenibacillus ehimensis after 20 minutes was observed the chito-ligosacharides with polymerization degree between 3 and 6 units. Evaluating these results, it was verified that the production of chitosan-oligosaccharides is possible, using a simultaneous process / A obten??o de oligossacar?deos, a partir da quitosana, tem despertado interesse da ?rea farmac?utica nos ?ltimos anos devido as suas in?meras propriedades funcionais. Por?m, o grande desafio encontrado ? manter uma produ??o constante e eficiente. A alternativa proposta por este trabalho foi estudar a viabilidade de desenvolver uma tecnologia integrada e de baixo custo. A estrat?gia utilizada foi a obten??o dos olig?meros por meio de hidr?lise enzim?tica utilizando enzimas quitosanol?ticas obtidas diretamente do caldo fermentado, eliminando dessa forma as etapas envolvidas na purifica??o de enzimas. As duas cepas produtoras de quitosanases selecionadas para o trabalho, Paenibacillus chitinolyticus e Paenibacillus ehimensis, foram avaliadas quanto ao comportamento em meio de cultivo contendo a??cares simples e em rela??o as varia??es de pH do meio. O meio de cultivo para a indu??o e produ??o das quitosanases foi desenvolvido atrav?s da adi??o de quitosana sol?vel como fonte de carbono. A quitosana sol?vel foi obtida utilizando solu??o de ?cido clor?drico 0,1 M e posterior neutraliza??o com NaOH 10 M.

Esses dois complexos enzim?ticos apresentaram estabilidade quando armazenadas a -20?C por at? 91 dias. As enzimas presentes no caldo fermentado pelo Paenibacillus chitinolyticus, quando expostas ? temperatura de 55?C e pH 6,0, onde a atividade ? m?xima, apresentaram perda de 50% da atividade ap?s 3 horas. Enquanto que, para o complexo produzido pelo Paenibacillus ehimensis, ap?s 6 dias de exposi??o, 100% da atividade foi detectada. Os quito-oligossacar?deos obtidos a partir da hidr?lise de uma solu??o de 1% de quitosana, utilizando o complexo enzim?tico produzido pelo Paenibacillus chitinolyticus, apresentaram-se em maior quantidade ap?s 9 horas de hidr?lise e utilizando o complexo produzido pelo Paenibacillus ehimensis, ap?s 20 minutos pode-se observar os quito-oligossacar?deos com grau de polimeriza??o entre 3 e 6 unidades.

El pintor quiteño, Miguel de Santiago (ca. 1630-1706), siendo especialista en series pictóricas, emprendió un estudio anatómico artístico para representar a las imágenes religiosas con un elevado nivel de realismo. Es así que pintó una serie de ocho pinturas conmemorando la tradición de las Siete Palabras de Cristo. El carácter vanguardista de esta serie elaborada en la Audiencia de Quito a mediados del siglo XVII, hizo que se las asocie con una leyenda. Actualmente una de estas obras se encuentra en el Museo de los Descalzos del Rímac en la ciudad de Lima, y constituye el objeto de estudio para la presente tesis. Así que se emprendió una labor investigativa dentro de archivos, bibliotecas, museos, entre otras estancias del Ecuador y Perú, con el fin de identificar la procedencia, atribución, contexto y motivos de elaboración, conexión y variantes de la leyenda, finalmente se analiza sus funciones y significados a lo largo de toda su existencia. / The quitenian painter Miguel de Santiago (ca. 1630-1706) had being a specialist in pictorical series. He started an artistic and anatomic study in order to represent religius images with a high realism level. Thus he painted a serie with eight paintings depicting Christ’s Seven words on the cross. The avangardist pictorical serie made in the Audiencia de Quito in the mid seventeenth century, was associated with a legend. Currently one of these paintings is in the Descalzo´s Museum in Rímac district at Lima city. Therefore this painting is the subjet to study in this thesis. The researching had taken place in archives, libraries, museums and other locations in Ecuador and Peru. In order to indetify the provenance, atribution, context and reasons for the creation, legend’s relations and variants. Finally a survey of functions and meanings throughouth the painting’s existence. / Tesis

[ES] La región de América Latina ha tenido un fuerte crecimiento poblacional en las últimas décadas con una concentración a la par en núcleos urbanos, generando ciudades de gran tamaño. Junto a esos procesos demográficos, se ha generado la necesidad de construir sistemas de transporte público, y en las grandes ciudades latinoamericanas han surgido sistemas de metro, que en ocasiones surgen de inversión estrictamente de fondos públicos y en otros casos de una participación mixta con concesiones donde existe inversión pública pero también de las empresas privadas ante una época que ha generado una oleada de construcción de sistemas de metro en la región. La presente tesis realiza un estudio del estado del arte con un análisis de los modelos de gestión y administración de los sistemas de metro, partiendo desde el estudio de los actores y participantes en cada una de las macro etapas de los proyectos de desarrollo de un sistema de metro, avanzando en las relaciones de los niveles de gobierno con capacidad de inversión y gestión, grados de libertad al momento de diseñar un sistema de metro y experiencia para administrar el proyecto, alternativas de financiamiento para los proyectos de metro, riesgos asociados y mecanismos de mitigación de los mismos, y de manera especial los modelos de contratación y concesiones de metros. La investigación continúa con una revisión de los sistemas de metro existentes en América Latina, con un estudio descriptivo de las características físicas y de servicio de cada operación, así como los parámetros de demandas y económicas. Mediante una comparación con metros en otras regiones del mundo se logra una determinación de los elementos singulares que caracterizan a los metros de América Latina. El penúltimo capítulo de la investigación estudia los casos de concesiones en la región tanto de éxito como de fracaso, con un análisis de cuáles son los factores críticos en unos y otros casos. Y en base a ello se cierra la tesis con un último capítulo que genera una propuesta de un caso práctico para desarrollar una concesión con los aprendizajes adquiridos, para el mediano y largo plazo del sistema del Metro de Quito. / [CA] La regió d'Amèrica Llatina ha tingut un fort creixement poblacional en les últimes dècades amb una concentració a l'una en nuclis urbans, generant ciutats de gran grandària. Al costat d'aqueixos processos demogràfics, s'ha generat la necessitat de construir sistemes de transport públic, i en les grans ciutats llatinoamericanes han sorgit sistemes de metre, que a vegades sorgeixen d'inversió estrictament de fons públics i en altres casos d'una participació mixta amb concessions on existeix inversió pública però també de les empreses privades davant una època que ha generat una onada de construcció de sistemes de metre a la regió. La present tesi realitza un estudi de l'estat de l'art amb una anàlisi dels models de gestió i administració dels sistemes de metre, partint des de l'estudi dels actors i participants en cadascuna de les macro etapes dels projectes de desenvolupament d'un sistema de metre, avançant en les relacions dels nivells de govern amb capacitat d'inversió i gestió, graus de llibertat al moment de dissenyar un sistema de metre i experiència per a administrar el projecte, alternatives de finançament per als projectes de metre, riscos associats i mecanismes de mitigació d'aquests, i de manera especial els models de contractació i concessions de metres.

I sobre la base d'això es tanca la tesi amb un últim capítol que genera una proposta d'un cas pràctic per a desenvolupar una concessió amb els aprenentatges adquirits, per al mitjà i llarg termini del sistema del Metre de Quito. / [EN] The Latin American region has had a strong population growth in recent decades with a concentration in urban centers, generating very populous cities. Together with these demographic processes, the need to build public transportation systems has arisen, and metro systems have emerged in large Latin American cities, which sometimes arise from investment strictly from public funds and in other cases from a mixed participation with concessions, where public investment is shared with that of private companies, at a time when a wave of construction of metro systems has been generated in the region. This thesis carries out a study of the state of the art with an analysis of the management models of the metro systems, starting from the study of the actors and participants in each of the macro stages of the development projects of a system of metro, advancing in the relations of levels of government with investment and management capacity, degrees of freedom when designing a metro system and experience to manage the project, financing alternatives for metro projects, associated risks and mechanisms of mitigating them, and especially the contracting models of metro concessions. The research continues with a review of the existing metro systems in Latin America, with a descriptive study of the physical and service characteristics of each operation, as well as the demand and economic parameters. Through a comparison with metro systems in other regions of the world, a determination of the unique elements that characterize Latin American metros is achieved. / Bastidas Zelaya, EA. (2023).

[ES] Los sistemas de buses de tránsito rápido (Bus Rapid Transit, BRT por sus siglas en inglés) han experimentado un gran crecimiento en los últimos años, pues más de 170 ciudades tienen algún tipo de sistema BRT. La evidencia empírica acerca de la relación entre el entorno urbano y estos sistemas todavía requiere ser estudiada, especialmente en las urbes en desarrollo que no disponen de información a pie de calle para realizar análisis en el nivel de las estaciones. En este contexto, el primer objetivo de la investigación fue generar datos a microescala (a pie de calle) del entorno próximo a las estaciones del sistema BRT de Quito, mediante métodos e instrumentos de análisis de campo, así como seguimientos, recopilación técnica de información de características del entorno urbano y encuestas. Además, se propuso utilizar los sistemas de información geográfica (SIG) para el manejo y análisis de los datos. Así, se obtuvieron mapas que representan la densidad de la población a escala de manzana y a escala de segmentos: la densidad de la edificación, la mezcla de usos de suelo (servicios, entidades públicas, escuelas, comercio, etc.); mezcla vertical (es decir, usos de vivienda, comercio y oficina en el mismo edificio) y características de espacio público (seguridad vial, ancho de acera, topografía, etc.). Se propuso también identificar el umbral de distancia máxima mediante el método de seguimiento, cuyo hallazgo revela que este umbral se sitúa en una distancia de 600 metros En relación al objetivo de analizar las características de los usuarios del sistema BRT y el comportamiento del viaje a través de una encuesta de intercepción, los resultados establecen que la mayoría de los usuarios encuestados corresponden al grupo femenino con formación académica universitaria que utiliza el transporte por trabajo. El siguiente objetivo fue determinar de forma cuantitativa la relación entre el sistema BRT de Quito y las características del entorno urbano en un umbral de distancia de 600 m, en 42 puntos a través del análisis estadístico multivariante (modelo de regresión múltiple). Los resultados señalan que la densidad de los segmentos del viario con acera entre 3 y 4 metros, la densidad del equipamiento de administración pública son variables significativas y positivas. Asimismo, la distancia al centro de la ciudad (accesibilidad regional) y la distancia a los destinos dentro de los 400 metros, (accesibilidad local), son dominios con signo negativo. Mientras que, la densidad no tiene un poder explicativo en el modelo de demanda del sistema tipo BRT de la ciudad de Quito. Asimismo, se planteó el examinar las cualidades del contexto inmediato de las mismas 42 estaciones del sistema BRT de Quito dentro de un umbral de distancia de 600 m a través del análisis estadístico multivariante. Los resultados muestran que la accesibilidad local, es decir, la distancia a la parada destino, el índice de rodeo (relación entre la distancia a pie medida a través de la red y la distancia euclidiana), el logaritmo de la densidad de la población se correlaciona de manera positiva con la distancia a pie. Mientras que, la densidad de los estratos (medio alto y alto), la densidad no residente (personas que trabajan, estudian o realizan otras actividades) y la distancia a la parada destino son variables significativas y con signo negativo. Otro objetivo de estudio fue tipificar el entorno urbano próximo de las 42 paradas en un umbral de distancia de 600 metros del sistema BRT de Quito a través del análisis estadístico factorial y los clústeres. Las características del entorno se clasificaron en tres factores. / [CA] Els sistemes de busos de trànsit ràpid (Bus Rapid Transit, BRT per les seues sigles en anglés) han experimentat un gran creixement en els últims anys, perquè més de 170 ciutats tenen algun tipus de sistema BRT. L'evidència empírica sobre la relació entre l'entorn urbà i estos sistemes encara requereix ser estudiada, especialment en les urbs en desenvolupament que no disposen d'informació a peu de carrer per a realitzar anàlisi en el nivell de les estacions. En este context, el primer objectiu de la investigació va ser generar dades a microescala (a peu de carrer) de l'entorn pròxim a les estacions del sistema BRT de Quito, mitjançant mètodes i instruments d'anàlisis de camp, així com seguiments, recopilació tècnica d'informació de característiques de l'entorn urbà i enquestes. A més, es va proposar utilitzar els sistemes d'informació geogràfica (*SIG) per al maneig i anàlisi de les dades. Així, es van obtindre mapes que representen la densitat de la població a escala de poma i a escala de segments: la densitat de l'edificació, la mescla d'usos de sòl (serveis, entitats públiques, escoles, comerç, etc.); mescla vertical (és a dir, usos d'habitatge, comerç i oficina en el mateix edifici) i característiques d'espai públic (seguretat viària, ample de vorera, topografia, etc.). Es va proposar també identificar el llindar de distància màxima mitjançant el mètode de seguiment, la troballa del qual revela que este llindar se situa en una distància de 600 metres En relació a l'objectiu d'analitzar les característiques dels usuaris del sistema BRT i el comportament del viatge a través d'una enquesta d'intercepció, els resultats estableixen que la majoria dels usuaris enquestats corresponen al grup femení amb formació acadèmica universitària que utilitza el transport per treball. El següent objectiu va ser determinar de manera quantitativa la relació entre el sistema BRT de Quito i les característiques de l'entorn urbà en un llindar de distància de 600 metres, en 42 punts a través de l'anàlisi estadística multivariant (model de regressió múltiple). Els resultats assenyalen que la densitat dels segments del viari amb vorera entre 3 i 4 metres, la densitat de l'equipament d'administració pública són variables significatives i positives. Així mateix, la distància al centre de la ciutat (accessibilitat regional) i la distància als destins dins dels 400 metres, (accessibilitat local), són dominis amb signe negatiu. Mentre que, la densitat no té un poder explicatiu en el model de demanda del sistema tipus BRT de la ciutat de Quito. Així mateix, es va plantejar l'examinar les qualitats del context immediat de les mateixes 42 estacions del sistema BRT de Quito dins d'un llindar de distància de 600 metres a través de l'anàlisi estadística multivariant. Els resultats mostren que l'accessibilitat local, és a dir, la distància a la parada destine, l'índex de marrada (relació entre la distància a peu mesurada a través de la xarxa i la distància euclidiana), el logaritme de la densitat de la població es correlaciona de manera positiva amb la distància a peu. Mentre que, la densitat dels estrats (mig alt i alt), la densitat no resident (persones que treballen, estudien o realitzen altres activitats) i la distància a la parada destine són variables significatives i amb signe negatiu. Un altre objectiu d'estudi va ser tipificar l'entorn urbà pròxim de les 42 parades en un llindar de distància de 600 metres del sistema BRT de Quito a través de l'anàlisi estadística factorial i els clústers. Les característiques de l'entorn es van classificar en tres factors. / [EN] Bus Rapid Transit (BRT) systems have experienced tremendous growth in recent years, with more than 170 cities having some form of BRT system. Empirical evidence about the relationship between the urban environment and these systems still needs to be studied, especially in developing cities that do not have street-level information for station-level analysis. In this context, the first objective of the research was to generate micro-scale data (at street level) of the environment near the stations of Quito's BRT system, through field analysis methods and tools, as well as monitoring, technical collection of information on urban environment characteristics and surveys. In addition, the use of geographic information systems (GIS) was proposed for data management and analysis. As a result, maps were obtained that represent population density at the block scale and at the segment scale: building density, mix of land uses (services, public entities, schools, commerce, etc.), vertical mix (i.e., housing, commerce and office uses in the same building) and public space characteristics (road safety, sidewalk width, topography, etc.). Also, it was proposed to identify the maximum distance threshold using the tracking method, the finding of which reveals a distance of 600 meters. Regarding the objective of recognizing the qualities of the users of the BRT system and the characteristics of the trip through the application of an intercept survey, the results establish that most of the surveyed users correspond to female group with university education who use the transport for work. The next objective was to quantitatively determine the relationship between Quito's BRT system and the characteristics of the urban environment at a distance threshold of 600 meters, at 42 locations through multivariate statistical analysis (multiple regression model). The results indicate that the density of road segments with sidewalks between 3 and 4 meters, the density of public administration equipment are significant and positive variables, likewise, the distance to the city center, regional accessibility and the distance to destinations within 400 meters, local accessibility, are domains with a negative sign. Meanwhile, density has no explanatory power in the demand model of the BRT type system in the city of Quito. Likewise, it was proposed to examine the qualities of the immediate context of the same 42 stations of the Quito BRT system within a distance threshold of 600 meters through multivariate statistical analysis. The results show that local accessibility, meaning the distance to the destination stop, the rounding index (ratio between the walking distance measured through the network and the Euclidean distance), the logarithm of the population density correlates positively with the walking distance. While, stratum density (upper middle and high), non-resident density (people working, studying or performing other activities) and distance to the destination stop are significant variables and with negative sign. Another study objective was to typify the proximate urban environment of the 42 stops within a distance threshold of 600 meters of the Quito BRT system through statistical factor analysis and clustering. The characteristics of the environment were classified into three factors. / Núñez Basantes, AC. (2024).
