Pujantiyo, Bambang Slamet with Yoshio Hanzawa and Atsushi Fukuda, "The Impact of Transportation Projects on Jabotabek, Indonesia", 1991
The lack of transportation facilities has been the slackening force to the economic development of most Southeast Asian countries in recent years. A lot of transportation projects has been purposed to alleviate this pressing problem. However, each project is being appraised individually without considering its economic importance with other proposed projects. Economic evaluation is considered on a short term basis neglecting the effects of the project to the whole transportation system on the long term. There is no coordination and systematic implementation to analyze whether a project is important or will be approved first considering the limited funds and resources available. On this research, a system dynamics model is proposed which can analyze the coordination of some projects in terms of economic evaluation.The reliability of this model is tested in Jabotabek, Indonesia which is composed of one urban area and three surrounding areas. The transportation facilities that are considered in this study area are the port which serves as an import-export terminal for products and resources, the trunk roads which provide the link between the urban area and the suburban areas, and other urban transportation facilities located within the urban area.Comparing the trend of the socio-economic growth and development of each expected scenarios is the defined areas, the result shows the importance of coordinating the implementation of transportation facilities.
