AccesoBarrio - Medición de la accesibilidad urbana usando perfiles demográficos y OpenStreetMap

Stefan Steiniger, Cristian Fuentes, Rodrigo Villegas, Ricardo Ardiles, Carolina Rojas, Ebrahim Poorazizi

Resumen


Presentamos una herramienta web que permite la cuantificación de la accesibilidad focalizada en el ciudadano y en el urbanista como usuario. La plataforma AccesoBarrio (ingles: WalkMyPlace) toma la localización y el tiempo de viaje especificados por un usuario, y evalúa el área accesible en tiempo real. Se calcula un puntaje de accesibilidad a partir de un conjunto de destinos frecuentemente asociados a la “Calidad de Vida”, incluyendo instancias tales como tiendas de comestibles, zonas recreativas, y escuelas, entre otros. La plataforma permite analizar la accesibilidad para distintos perfiles demográficos. Usando perfiles demográficos creados por Frank y Ulmer (2003) mostramos que niños, adultos y mayores tienen diferentes niveles de accesibilidad en Gran Santiago, Chile. Por ejemplo, valores de los dos grupos de adultos y de niños muestran una diferencia de hasta 22 (de 100) puntos para el mismo barrio. En general, el modelo muestra que los adolescentes poseen la peor accesibilidad.
