Abstract
Based on space syntax theory, the spatial accessibility of the road network in Wuhan Metropolitan Area has been quantitatively analyzed by building a series of accessibility variables. Topologic connectivity in the accessible rings appears to be broken; traffic axis network is in spatial structure of hub-and-spoke and fishbone-like. Meanwhile, the differences in classified road network have led to inefficiency of its network servo and its ever-worsening capability to respond to traffic jams. Besides, two band-like integrated cores of which one is east to west along the Yangtze River and the other is north to south along Beijing to Guangzhou Railway, have become the first level traffic axis in the whole network, which is responsible for the connectivity of the entire metropolitan area network. This consequently has strengthened the dominant position of Wuhan which is located on the bands’ crossing. In short, the spatial accessibility of that classified space morphology, the urban system, the transport infrastructure as well as the social and economic development of Wuhan Metropolitan Area are highly interrelated to each other, especially to the high level highway network featured by freeways, the development level of which is well in line with that of road network accessibility.
Highlights
Spatial accessibility has become a prerequisite to the integration of the urban center and its circumference [1]

Summary
Spatial accessibility has become a prerequisite to the integration of the urban center and its circumference [1]. Are the exchange opportunities and potentiality in social, economic, cultural and technology sections between the two parts It is the focus of current researching field that revealing the geo-spatial characteristics of the metropolitan area and analyzing and evaluating the spatial structure of that by studying its transport network and spatial accessibility between the urban center and its circumference [4]. Quantitative evaluation of accessibility has become popular It mainly focuses on urban transportation and services as well as its location assessment. Taking Wuhan Metropolitan Area as an example, this article aims at providing theoretical and empirical reference to Metropolitan Transportation Planning in China by evaluating the spatial law of metropolitan road network from different perspectives by analyzing a series of spatial syntactic variables built by GIS spatial analysis techniques
