Structural barriers to walkability and accessibility at neighborhood scale. Three case study in Santiago de Chile

Considering both the relevance of accessibility to urban goods and services or geography of opportunities in the quality of life of urban inhabitants, and the fact that walking represents the main mode of transportation in Greater Santiago —34,6% of trips, according to EOD 2012 (Universidad Alberto...

description Considering both the relevance of accessibility to urban goods and services or geography of opportunities in the quality of life of urban inhabitants, and the fact that walking represents the main mode of transportation in Greater Santiago —34,6% of trips, according to EOD 2012 (Universidad Alberto Hurtado, 2014)—, the aim of this research is to analyze and compare the structural barriers that affect the walkable area at the neighborhood scale, as well as estimate their possible effects on mobility patterns and access to goods and services, in three housing estates in Greater Santiago: Población Juan Antonio Ríos, sector 3B (Independencia), Villa San Cristóbal (Recoleta) and Villa Los Sauces (La Florida). For each case, the main material barriers are identified, whether natural (rivers, hills) or artificial (roads, under/over crossings) and some of intangible barriers (associated with road or crime safety). The maximum theoretical area (Euclidean) and that of the “actual” walkable neighbourhood are compared through network analysis (based on 20 minute journeys), considering the crossing conditions of main roads, quantifying the effects over time and distance, and accessibility to goods and services. In addition, the configuration of the road and pedestrian network is analysed, contrasting their local and global integration, based on axial maps. Finally, the movement patterns of the inhabitants is analysed based on the EOD data. The results showed a clear decrease of the actual walkable neighbourhood area (to one third of the Euclidian area) product of the urban grid and the various existing barriers, which reflects on the accessibility to goods and services by walking. These results allow us also to propose that although a greater average distance is not related to a greater walkable area, closeness to well served centralities associate to in with the prevalence of walking as a transport mode.

Dada la relevancia de la accesibilidad a bienes y servicios urbanos en la calidad de vida de los habitantes, y considerando que la caminata representa el principal modo de transporte en el Gran Santiago —34,6% de los viajes, según la Encuesta de Origen y Destino de 2012 (Universidad Alberto Hurtado, 2014)—, la presente investigación tiene como objetivo analizar y comparar las barreras estructurales que inciden en el área caminable a escala de barrio y estimar sus posibles efectos en los patrones de movilidad y acceso a bienes y servicios, en tres conjuntos habitacionales del Gran Santiago: población Juan Antonio Ríos sector 3B (Independencia), villa San Cristóbal (Recoleta) y villa Los Sauces (La Florida). Para cada caso, se identificaron las principales barreras materiales, ya sean naturales (ríos, cerros) o artificiales (carreteras, pasos bajo/sobre nivel) y algunas barreras intangibles (asociadas a la seguridad vial o delictual). Se comparó la superficie teórica máxima del barrio caminable (euclidiana) con la “real” calculada mediante análisis de red (sobre la base de recorridos de 20 min), considerando las condiciones de cruce de las principales vías, cuantificando sus efectos en tiempo y distancia y la consiguiente accesibilidad a equipamiento y servicios. Además, se analizó la configuración de la trama vial y peatonal, contrastando su integración a escala local y global basada en mapas axiales. Finalmente, se analizaron los patrones de movilidad de la población según datos de zona EOD 2012.Los resultados muestran una clara disminución del área real del barrio caminable (a un tercio del área euclidiana), producto de la trama y de las diversas barreras existentes, lo que se refleja en la accesibilidad a bienes y servicios vía caminata. Estos resultados permiten proponer además que, si bien una mayor distancia promedio de caminata no se relaciona con una mayor área caminable, la cercanía a centralidades sí se asocia con la prevalencia de este modo de transporte.
