ACCESSIBILITY ANALYSIS FOR NAKHON RATCHASIMA LIGHT RAIL TRANSIT STATION
Keywords:Accessibility, Geographic Information System, Light Rail Transit, Spatial Analysis, Nakhon Ratchasima
Nakhon Ratchasima Municipality has planned to develop and reform the basic infrastructure and transportation by constructing the Light Rail Transit (LRT) as an alternative public transport system. Moreover, are development to facilitate for public transport connections and the walkway safety are also included in the development plan. This present research aimed to identify catchment areas around LRT stations by referring to acceptable walking distances to LRT stations as follows - 324 meters, 400 meters, 500 meters, 648 meters, 800 meters, and 960 meters. These walking distances were used with Circular Buffer and Network Analyst Service Area techniques in order to calculate for the proportions of LRT accessibility. Employing ArcGIS 10.4 program for desktop to analyze spatial data, this research found that the areas around LRT stations in the urban area of Nakhon Ratchasima had higher accessibility level than the suburbs. The data indicated that the areas around the stations located in the urban area were suitable for pedestrian network development. In order to develop mass transit system within the area of Nakhon Ratchasima Municipality, it was suggested that feeder system in the suburbs should also be developed with less proportion of LRT accessibility than the urban area for users’ convenience. It was expected that the more accessible the LRT stations was, the more job opportunities and residential space would be available.
