Green corridors and sustainable urban connectivity. Insights from the case of Walter Andrade Avenue in Quevedo, Ecuador

Abstract

This study examines the relationship between green corridors and sustainable urban connectivity in mid-sized cities, using the case of Walter Andrade Avenue in Quevedo, Ecuador. The study addresses the issues of public space fragmentation, pedestrian discontinuity, limited universal accessibility, and a lack of green infrastructure along a strategic road corridor in the city. Methodologically, a mixed-methods approach was adopted, incorporating structured observation, spatial analysis, photographic documentation, surveys, and institutional interviews, aimed at evaluating the physical, environmental, and social conditions of the corridor. The results show that the avenue has a predominantly vehicular configuration, with discontinuous sidewalks, scattered vegetation, a lack of effective shade, architectural barriers, and poor coordination between the roadway, sidewalk, and green areas. However, spatial opportunities were also identified, particularly in underutilized side strips and areas with potential for tree planting, pedestrian dwell time, and landscape transition. It is concluded that the implementation of a sustainable green corridor on Walter Andrade Avenue constitutes a viable strategy for improving active mobility, accessibility, environmental comfort, and urban integration. The study provides design guidelines applicable to mid-sized cities facing urban expansion, vehicle-dominated environments, and a shortage of public green space.
