In cities today, the possibility of being confined is not only applicable to fixed areas, like work or home, but it may also occur while moving. This is because high levels of mobility, long distances, and extended hours of daily travel, along with monotonous and difficult mobility experiences may lead some to “miss” the city, in a tunnel‐like manner. In the context of urban daily mobility practices, this paper argues that although the possibility for expanding places by daily mobility exists, increasingly urban experiences in cities like Santiago de Chile, involve a simultaneous tunneling or confining effect, reducing the possibilities of encounter and interaction, which are the essence of urban experience. Using an ethnographic approach to urban daily mobility practices in Santiago de Chile, this paper discusses how mobility relates to place making and to urban inequality and then analyzes the way place enlargement and confinement occur.

An ethnographic approach to the everyday mobility of Santiago's residents is applied, in order to describe the way in which urban dwellers experience urban fragmentation by devising different mobility strategies to weave their way through the disconnected, interrupted and segregated spatialities into which the city has been decomposed, resulting in fragmentation of

RESUMENEl presente trabajo genera una aproximación a la comprensión de la exclusión social desde la movilidad cotidiana urbana por medio del estudio de la accesibilidad. Este enfoque teórico-metodológico permite evidenciar las múltiples barreras de accesibilidad que los viajeros encuentran diariamente en sus trayectos por la ciudad, las cuales van dando una "espesura" a la experiencia del tiempo-espacio. El documento primero contrasta las conceptualizaciones tradicionales de accesibilidad, posteriormente genera una propuesta para su análisis en la vida cotidiana a través de métodos etnográfi cos, y a modo de ejemplo, presenta dos casos de viajeras desde el sector norte de la ciudad de Santiago, una de ingresos medio bajos y otra de ingresos altos. Los resultados permiten identifi car dicha espesura en las barreras de accesibilidad y cómo estas se conjugan para dar cuenta de la complejidad que las personas enfrentan para acceder a las oportunidades de la ciudad, las estrategias que emplean y las diversas formas de exclusión urbana que a partir de ellas se desprenden.Palabras clave: Movilidad, accesibilidad, barreras, espacialidad, vida cotidiana. ABSTRACTThis paper presents an approximation of social exclusion from the point of view a daily mobility and through the study of accessibility. This theoreticalmethodological approach permits the documentation of multiple accessibility barriers that commuters confront daily on their commutes through the city. These barriers generate a sort of "weight" to the time-space experience. The document fi rst contrasts traditional conceptualizations of accessibility and then proposes a way to analyse this in daily life using ethnographic methods, and provides two case studies of female commuters living in the Northern part of Santiago, one who is middle-low income and the other who is high income. The results identify the way in which accessibility barriers can be compounded resulting in diffi culty in accessing opportunities in the city, the strategies they employ and the diverse forms of social exclusion that can emerge.

A mobilidade permite analisar como, com quem, onde e por que pessoas, objetos, ideias, entre outros, se movem. Não há mobilidade, mas uma multiplicidade de mobilidades, com diferentes características e implicações para as pessoas. Isto é particularmente evidente quando observamos a experiência espaço-tempo diferenciada entre homens e mulheres, que muitas vezes resulta em situações de desigualdade e exclusão. No entanto, ainda é necessário aprofundar a análise dessasexperiências diferenciadas. Ao observar as práticas de mobilidade e as decisões de homens e mulheres desde uma perspectiva etnográfica, o papel da interdependência nas estratégias de mobilidade em cidades metropolitanas como Santiago pode ser revelado, particularmente em termos das implicações da mobilidade sobre os cuidados.

The implementation of the Smart City (SC) model in Santiago, Chile has not heralded any significant interventions in terms of scale, urban impact, amount invested, technological innovation or architectural design. Instead, material interventions have been small and have had little more than a superficial impact upon the perceptions of citizens. The significance of observing ‘Smart’ interventions in Santiago involves analysing their implementation under a provincialising lens in order to observe the way local experience transforms monist ways of thinking about SCs. Based on ethnographic observation of an SC intervention (in Paseo Bandera, Santiago de Chile), four principles of intervention were identified: democratisation of the city, spatial appropriation by citizens, social and technological innovation and local and territorialised interventions. These principles help to identify the intervention as an urban placebo, which the article argues works through the fictions of effective interventions and urban image improvement that seek to participate in worlding practices whilst, in reality, very little is being improved or effectively addressed in the city. Paseo Bandera SC intervention presents a narrative of modern, sustainable and technologically advanced urban planning in the form of specific material interventions, when in fact it involves very little modernity, sustainability or technology, and is little more than a continuation and evolution of the neoliberal urban model that exists in Chile.
