Resumen
The tradition of transport planning in Thailand began as recently as 1960 with the Greater Bangkok Plan, and the 1971 Bangkok Transportation Study. Since then the country has incrementally developed its transport planning practice. This paper provides a detailed description of Thailand's transport master plan for urban areas and its study process. It introduces the Office of Traffic and Transport Policy and Planning, which is responsible for formulating the plan. It describes the master plan study process of the regional cities, and provides three case studies in Si Sa Ket, Chiang Mai, and Lampang to illustrate the process in practice. The transport plan of Bangkok, the capital city, is described separately, as it focuses more on the planning of a mass-transit system. The study reveals a number of lessons learned.
