The Study of Urbanization Effect on the Land Use Changes and Urban Infrastructures Development in the Metropolitan Areas, Thailand

Abstract

Bangkok has expanded considerably between 1991 - 1996. Which, the key factors contributed to the expansion consisted of real estate, business development and manufacturing industry. The horizontal expansion continued until 1991, after that Bangkok has increased its vertical expansion, especially in the inner and urban areas. The increasing in term of population causes the inner zone growth with high concentration rate, however, the suburban areas are characterized as of urban sprawls with the major expansion of road network. Those connectivities cut through the heart of Bangkok with the surrounding provinces. Currently, Bangkok has been continued its expansion in all directions, with high number of private cars and less users' choices for public transportation, wich resulted in land-use changes, pollution, and traffic problems. The objective of this research is to study pattern of urban expansion and rate of changes in land use and infrastructure development by analyzing the land use changes in Bangkok and metropolitan and infrastructure development during the past 10 years, 2009 - 2019. The comparing of growth can be performed based on the study of satellite imagery, Path 129 Row 50 and Path 129 Row 51. From the result of analysis, it was found that road intersection density had an effect of the urban density areas. Finally, the Land Change Modeler (LCM) was used to explore and recommend for the appropriate ways for urban planning and development corresponding to the changes and responsive to the people in more sustainable way.
