Association of the TOD Measures around Rail Transit Stations in Bangkok Metropolitan

Proper development within the station catchment area is a key factor in encouraging transit use and alleviating severe urban traffic congestion. While the railway development has been in progress in Bangkok for over decades, the area development around the station was not in such a way that enhance people to shift away from private cars to the railway. This study examined the patterns of relationships among the characteristics of the catchment area around the 122 urban railway stations based on 5d's measures of transit-oriented development (TOD): density, diversity, design, destination accessibility, and distance to transit. Multiple correspondence analysis revealed the associations between the TOD factor levels and characterized the station catchment areas based on TOD measures, for example, high density employment and commercial land were found associated with a high degree of diversity, while low density residential areas were associated with low destination accessibility and poor transit access, etc. The findings shade light to enhance the station catchment area development to encourage the railway use.
