Evaluation of 3D-Traffic Accessibility Based on Space Syntax : A Case Study of Xian Subways
With the rapid development of urbanization in China, many cities begin to build subway to relieve the increasing traffic pressure. How to evaluate effect of subway on existing urban traffic system interests urban planners, who agree in adopting accessibility as measure to do it. Space Syntax is the most widely used theory for calculating accessibility measures. However, as the basis model of space syntax, axial-map is only aimed at 2D traffic system, not suitable for 3D situation. Based on natural-street map, a method is proposed which treats stations as junctions between subway and streets and rebuilds relation matrix in graph theory to calculate accessibility. Using the method, we analyze a case study of Xi’an city in china. It is found out that subway lead to change in accessibility to some extent depended on routine of subway and site of station, which implies it reasonable to layout subway along streets with high integration.
