A quantitative assessment of distribution and accessibility of service facilities in the buffer zone of Ben Thanh – Suoi Tien Metro line 01

Abstract

Transit-Oriented Development (TOD) is one of the key strategies for promoting sustainable urban development. Beyond providing significant benefits for mobility, metro systems exert a strong influence on the surrounding development areas, with an impact radius of up to 2 km. The Ben Thanh – Suoi Tien line is the first metro route in Ho Chi Minh City, playing an essential role in shaping travel behavior, enhancing land use and service values, and advancing sustainability. This study aims to apply two main groups of indicators, land use and accessibility to stations - to evaluate 14 stations along the Ben Thanh – Suoi Tien Metro Line. Data were collected through two primary methods: field video recording and survey questionnaires. The study employs correlation analysis, the K-means clustering algorithm, and radar charts to analyze the characteristics and potential relationships among observed variables. The findings reveal that the 14 stations are classified into two clusters, each exhibiting distinct features in terms of development levels and accessibility. This research contributes an important perspective to the implementation of future urban planning strategies.
