Public transport accessibility and the optimization of bus stop locations: a case study in Da Nang

Tóm tắt

This study evaluates the accessibility of public bus stops in Da Nang's city center to examine the alignment between spatial distribution and actual user demand within the context of promoting a shift toward public transit. Utilizing GIS spatial distribution analysis (within a 300–500m radius) combined with user surveys, the results indicate that current accessibility remains limited, particularly within the alleyways of older residential areas. Regression analysis identifies that 'Roadside Amenities' (40.8%) and 'Accessibility' (30.4%) are the key factors determining passenger satisfaction. Consequently, the study proposes a 300–500m threshold (equivalent to a 5–10 minute walk) as the optimal service radius, while providing a practical basis for improving pedestrian infrastructure and "first-mile/last-mile" connectivity for the bus system in Da Nang.
