Simulation based approach to evaluate the performance of FAR, MGC and set back as a means of density control in unplanned residential areas of DMDP area

Abstract

Furious pace of population growth in Dhaka City is gradually pushing it to a point where it will be no less than impossible to accommodate its inhabitants with required amenities and infrastructures. High population density in Dhaka warrants for a systematic way to be managed and well-served by existing resource and management capacity of this city. Especially the unplanned residential areas are at a menace. In this study, attempt has been taken to evaluate the role of FAR, MGC and set back as a means of density control in unplanned residential areas of DMDP area. To evaluate and arrive at a recommendable scenario of FAR, MGC and set back various alternative scenarios have been developed. Four study areas have been selected for simulating the alternative scenarios using a model developed for determining desirable density. The model used for the simulation purpose can be seen as an amalgam of two basic understanding that residential settlement should be developed providing minimum space for an individual, at the same time, there should be some space available for providing service facility for the increasing population. Results of the simulation suggest that if FAR is decreased by 5% and MGC is decreased by 15% then the unplanned residential areas can still be managed within a reasonable density limit.
