Analyzing the combined influence of accessibility and capacity of roads on urban density, land use mix and vitality

Abstract

Research focuses on analyzing the factors behind the change of urban form and its relationships. The main four urban form elements are recognized as Road network, land use mix, density and vitality based on natural movement and Transport land use feedback theory. A Road network is a combination of accessibility and capacity of the road, which can be referred as topological and mobility characteristics. Planners have identified theories and relationships, but never captured the combined influence of topological and mobility parameters of the road networks. It is required to analyze and quantify the Combined Influence of Accessibility and Capacity of Roads on Land Use Mix, Urban Density, and Vitality to identify the behavior of the urban form. This research was conducted in Colombo, Kurunagala, and Mawanlla. Results reveal the combined influence of accessibility and Capacity of roads to change land use, density and vitality. MATLAB 3D graphs, SPSS regression correlation analysis have been used to model real ground data. Cities have been tested for Accessibility and Capacity of road parameters. The study has recognized that the influence of accessibility varies from 50% - to 60% and the influence of the Capacity of Roads varies from 30% – to 45%. The study can be used for local and urban planning and will be a guide for preparing future plans and regulations.
