Development and Design of Spatial Fractal Calculation GIS System for Traffic Network
Han Zhen · Journal of Transport Information and Safety · 2010
Because traffic network data have such natures of multi-time,multi-scale,and multi-source,the study of its spatial distribution characteristics is an indispensable part of data mining and knowledge discovering using GIS-T.As spatial fractal characteristic is a significant and inherent property of traffic network,therefore,the design and development of a fractal calculation system can greatly facilitate analysis of temporal/spatial distribution characteristics of traffic network.Based on GIS and Visual Studio.NET,a spatial fractal calculation system was developed.In this paper,the architecture and major modules of this system were introduced.This system extends the spatial analysis functionalities of GIS-T,and constructs the spatial fractal analysis module.It can be used to quantitatively analyze the intensity,density,structure and connectivity of traffic network.Finally,the system was demonstrated with the traffic network of Guangzhou.
