Concentration Degree Analysis of Stroke-Based Urban Road Network Topology
Publication: ICTE 2011
Abstract
Existing road network evaluation methods have shortcomings to delineate the topology of the network. This paper uses dual approach to analyze the topology of the road network. To use the approach, stroke is introduced as the basis of the network and its abstracting principles are presented. Based on the principle of direction continuity, a program is designed to automatically decompose the road network into linear strokes. Then concentration degree is proposed as an indicator to quantify the centralization of road network. Its calculation method is presented. Finally, an application demonstrates the use of the indicator. The results suggest its practical benefits to quantitatively evaluate road network.
