Abstract：

Faced with the dilemma of high population density, insufficient supply facilities, traffic congestion, environmental pollution and other “diseases”, polycentric regional policy is underlined repeatedly in planning practice. But the performance of polycentric region is still lack of scientific research. This paper explores the transportation supply efficiency by calculating traffic circles of equal travel time with Google and Baidu Distance Matrix API platform. By a comparison of Dortmund in Rhine Ruhr polycentric region, German capital city Berlin, Chinese capital city Beijing, We find that in polycentric region, transportation supply efficiency is much better than that in mono-centric one, resulting in little traffic congestion. Public transport facility supply shows different result due to public investment and spatial political fragmentation. After brief reason analysis from spatial structure perspective, some suggestions are put forward to improve the efficiency of traffic supply and optimize the spatial structure of metropolitan area in China.
