The Thai GoodWalk Index and the Thai Walkability Index: their application to urban regeneration exemplified by a historic riverside neighbourhood in Bangkok, Thailand

Abstract

AbstractThe urban heritage regeneration strategy through walkability is widely accepted. However, in the context of a developing country, the tools to measure walkability, which are crucial for urban planning and development, still need to be improved. This article investigates ways to revitalise a run-down historic riverside area in Bangkok. It develops two indices, the Thai GoodWalk Index (TGWI) and the Thai Walkability Index (TWI). A hybrid of both indices is based on geospatial techniques and technology to optimise problem analysis processes, create problem-solving options, enhance spatial site selection decision capabilities, and assist urban planners in carrying out spatial scenario planning processes. It demonstrates how the GoodWalk Index has been employed to plan and prioritise urban development projects. This is exemplified by the Master Plan for the Regeneration of Kadeejeen-Klongsan, a historic riverside neighbourhood in Bangkok with limitations in density, functional mix of spaces, and access networks, especially in riverfront areas. The TGWI and TWI can be applied to the regeneration of other historic districts throughout Thailand.
