Abstract
The objective of this study is to explore the possibility of the use of a planning
support system in Singapore. With the advancement of the Geographic Information
System (GIS) technology that has been widely known for its analytical ability, there
is immense potential for a greater transparency and objectivity to be attained in the
process of making planning decisions using computer-aided programs. This does
not imply that planning support systems will bring about decisions that are totally
objective, as one will agree that land use policies are political by nature. What the
system does provide is an alternative perspective to land use allocations, which may
or may not justify certain plans, and thereby improving planning decisions.
The author has used the 'What If?' version 1.1 program, a planning support system
developed by Richard Klosterman in the analysis of land use plans of Singapore.
Three main sections: the suitability, growth and allocation components of land use
plans are considered in this study. The findings reveal that there is a need for a
contextualized planning support system if such systems are to be adopted and used
locally, as the 'What If?' program is unable to project land use allocation within a
'status quo' land size over the study period. Nonetheless, the author concludes that
there is immense potential in the use of analytical ability of the GIS technology in
the local urban planning arena, and this potential should be tapped to meet the
increasing demands and expectations of future land use planning.
