Evaluation for Low-carbon Land-use Transport Development with QOL Indexes in Asian Developing Megacities: a Case Study of Bangkok

Abstract

To decouple global economic growth with emission growth, a necessary local challenge is to develop attractive low-carbon transport systems in developing cities. Whether mass-transit development can be low-carbon against conventional road development in Asian developing megacities depends on how attractive they can be for local residents. This paper is aimed at evaluating the estimated long-term effects of rail-oriented development on transport-related CO₂ mitigation and Quality of Life (QOL) improvement in Bangkok. It develops a land-use transport model integrated with QOL indexes to estimate changes in travel demand up to 2050, considering the quality of transport modes and residential locations. Then, the model is applied to evaluating future scenarios of land-use transport development with different types of transport modes and station areas. The result showed that rail-oriented development can be more low-carbon than road-oriented development and can improve QOL, if planning is introduced to quality station-area development.
