ENVIRONMENTAL DECISION SUPPORT MANAGEMENT FOR URBAN TRANSPORTATION IN PUTRAJAYA CITY, MALAYSIA

The current tempo of efficient utilization of energy resources in the world, has led to paying more attention to environmental management of energy consumption. In this regard, urban transportation forms an important contributor in the field of energy. Urban activities are of considerable concern in the environmental management. And therefore the objectives of this study are to develop a GIS model, with an acceptable accuracy, to plan appropriate locations for main transportation destinations, and also to develop urban transportation network to give the issue of fuel consumption.

Putrajaya (a strategic city in Malaysia) has been chosen as the case study. Methodology of this study helps to select suitable sites for development of urban transportation network and main destinations. GIS as a powerful tool is applied for layers overlaying and interpretation of several scenarios. Developed GIS model is employed for establishing urban transportation networks planning and main transportation destinations. Based on the fuel consumption parameters, suitable maps are produced. These maps show there are non-suitable zones for most of main destinations. This research has successfully initiated the development of a scientific approach for current and future model development. The output of this model development has shown that the approach can be employed in transportation planning and main destinations suitability assessment at both the local and national structure plan levels. The results focus on the approaches such as road type change and location changes of the main destination landuses to upgrade accessibility.
