Effect of Public Transport Network on Urban Core and the Future Perspective in Bangkok, Thailand

City center is an essential components of urban structure that rules urban activities including economy, transport, and social interactions. In Bangkok, Thailand, the railway network is expanding and the expansion is expected to affect the city center locations. In this study we attempt to capture the effect of public transport network on the accumulation of three types of urban core facilities based on the spatial statistical approach, and estimate the future perspective of locations of those facilities. As a result we found that expected number of facilities in current urban core in Bangkok decreases and the number of facilities at stations on planned railways increases under certain conditions. The results can be utilized to estimate the future travel pattern and residential locations.
