    The growing relevance of promoting a transition of urban mobility toward more sustainable modes of transport is leading to efforts to understand the effects of the built environment on the use of railway systems. In this direction, there are challenges regarding the creation of coherence between the locations of metro stations and their surroundings, which has been explored extensively in the academic community. This process is called Transit-Oriented Development (TOD). Within the context of Latin America, this study seeks to assess the influence of the built environment on the metro ridership in the metropolitan area of Valpara & iacute;so, Chile, testing two approaches of influence area definition, one of which is a fixed distance from the stations, and the other is based on the origin and destination survey of the study area. The analysis is based on Ordinary Least Squares regression (OLS) to identify the factors from the built environment, which affects the metro's ridership. Results show that the models based on the area of influence defined through the use of the origin and destination survey explain the metro ridership better. Moreover, this study reveals that the metro system in Greater Valpara & iacute;so was not planned in harmony with urban development. The models demonstrate an inverse effect of the built environment on ridership, contrasting with the expected outcomes of a metro station designed following a Transit-Oriented Development approach.

    Simulación del cambio de uso de suelo en el área periurbana Villarrica-Pucón, Chile, 1998-2065: escenarios con y sin futuros proyectos viales

    La pandemia de Covid-19 intensificó la migración urbana hacia zonas turísticas, generando presiones de periurbanización no planificada. Este estudio analiza los cambios de uso de suelo en el área periurbana de Villarrica-Pucón (Chile) bajo dos escenarios al 2065: tendencial y con nuevos proyectos viales, utilizando el modelo Dyna-CLUE y datos satelitales (1998-2018). Los resultados muestran un crecimiento explosivo de parcelas de agrado (3.208 ha en 2018 a 12.000 ha en 2065), ocupando 8 veces la superficie urbana actual, pero con mínima influencia de las vías proyectadas en su localización. Esto revela que la proximidad a amenidades naturales (lago, volcán) predomina sobre la accesibilidad vial como factor de expansión. Se concluye que: (i) los instrumentos de planificación chilenos son insuficientes para regular la periurbanización turística, (ii) las infraestructuras de transporte no son el principal impulsor de cambios de uso de suelo en contextos lacustres, y (iii) se requieren modelos de gestión territorial que integren variables paisajísticas y riesgos naturales. El estudio aporta evidencia para reorientar políticas en áreas bajo presión turística-pospandemia.
