Abstract:
Retailing is the dynamic and evolving urban function in many small towns in Sri Lanka especially the towns originated and evolving to provide services for the surrounding residential population. This function is closely related to the economy of such towns. Location decisions of those activities in the towns are taken by the retail investors and by retail dealers merely based on their observations and experience. Meantime planners use zoning as a planning tool of managing land use of such towns. They use existing land use and trends in land use patterns as a basis and employ many raster based analysis methods in defining zones. Anyway there are criticisms that those created zoning plans dose not leveraging the economy and the wealth of such towns.
This study attempted to develop a modeling framework for decision making in identifying most attractive areas in a town for retail activities which can be used for the planners and for retail investors as well.
Retailing dense area of the Piliyandala town in the Colombo district of Western Province, Sri Lanka used for the study. This area was divided in to possible retail segments through prominent boundaries. Gravity of each segment based on level of retail attraction was calculated through the model.
This gravity levels (Probability) of each segment was calculated using two views of attraction. They are attraction based on the identified parameters on individual site and the attractiveness derived from the location of the catchment area. The model gives exact boundaries for the retail zones as it taken the retail segments trough the prominent boundaries.
As possible applications of the model by changing variables (attraction parameters) can be examine how the gravity levels are changing in the segments. In that way many planning intervention can be tested before implementing them by using this model.
