The application of systems thinking: a case study of Bangkok's transport situation

Abstract

It is generally accepted that traffic congestion is one of the most difficult problems that many cities confront. Bangkok is one of the cities struggling with this problem. Traffic congestion has an impact on both economic and social aspects of our lives. This thesis intends to clarify the overall traffic congestion situation in Bangkok by using holistic systems thinking; it also attempts to identify and to examine possible causes leading to this present traffic situation. Recognising the complexity of transport systems, the holistic systems thinking, developed by Bachels and others, is an approach employed in the thesis. Mental models and feedback diagrams are used to demonstrate the interrelationship between components of systems. The models provide general understanding and ideas; however, the validity of mental models can be measured by quantitative research methods. Key findings are: car-oriented policies lead to increasing car numbers; bribery and corruption are the main force driving the overall systems; distorted social attitudes toward car ownership and public transport also contribute to car use; the traffic situation will deteriorate unless anti-corruption campaigns and a public transport-oriented policy are emphasised.
