Abstract

Over the last decade, there has been a rapid increase in the amount of literature on the measurement of urban form simulation. The evolution of urban form studies have been conducted but in existing prediction changes of urban from have  not been practiced especially in Sri Lankan spatial planning context. In this background, this research examines the applicability of Fractal Geometry as a method to simulate changes in urban form in Sri Lankan Context and study the relationship between the Fractal Dimension (FD) of Distribution of Transport Network and Buildings. This paper employs mass-radius method to identify the relationship between urban form elements in City of Colombo. Accordingly, study has been conducted urban form studies and calculated FD of road and built-up area has been done using mass-radius method. Findings of the study have revealed a strong correlation and linear relationship between the fractal dimensions of road and built-form. Since there is a strong relationship between FDs of urban form elements and urban form can be simulated. Finally the study concludes Fractal Geometry as a method to simulate urban form changes in Sri Lankan context.
