Health Assessment of a 15-Minute Life Circle Around Rail Transit Based on the EWR-TOPSIS Method

Abstract

Integrating the construction of 15-minute living circles with the TOD (Transit-Oriented Development) concept to optimize residents' travel patterns, improve healthy development levels, and form a collaborative governance and sharing structure has become a crucial issue in contemporary urban development.This paper uses the 15-minute living circles around the Hefei Metro Line 1 stations as the research object, employing the Entropy Weight Method (EWM) and the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). Indicators were sorted from aspects of healthy travel, healthy environment, and healthy living to establish an evaluation system and quantify the health assessment of the 15-minute living circle. The findings include:1) In the spatial dimension, optimizing spatial layout enhances the competitiveness of public transportation, reduces residents' dependence on private cars, and promotes the formation of healthy travel patterns.2) In the temporal dimension, the improvement of the metro network and the increase in health facilities within the living circle diversify and facilitate residents' travel modes. Additionally, long-term construction of a healthy environment and changes in living habits help enhance overall urban health levels, creating a positive cycle.3) Optimizing the integration of the 15-minute living circle and the TOD concept requires strengthening planning and design, enhancing public transportation services, advancing healthy environment construction, promoting community participation, and implementing health education to further improve the health construction level of the 15-minute living circle.The construction of the 15-minute living circle around metro stations has driven the integrated development of metropolitan areas, enhanced the competitiveness of public transportation, and responded to the global health agenda.
