针对目前在做城市综合交通战略规划时，难以确定其交通定位及发展方向这一问题，通过分析各城市交通的发展水平及其城市的特征，应用主成分分析法建立了一套世界城市交通发展坐标体系，并应用非线性曲线拟合的方法，在坐标体系中拟合出了一条城市发展曲线，以确定城市的发展规律及发展特征，根据城市的不同发展阶段，结合发展曲线的变化规律，分析了坐标之间的相互关系，可以为城市的发展提供经验借鉴。该世界城市交通发展坐标体系可以应用到世界各城市，为相关部门和专家制定综合交通发展战略规划提供参考。

To address the difficulty of determining transportation positioning and development direction in current comprehensive urban transportation strategic planning, this study analyzes the transportation development levels and urban characteristics of major cities worldwide and establishes a world urban transportation development coordinate system using principal component analysis(PCA).By applying nonlinear curve fitting, a city development curve is derived within this coordinate system to identify the developmental laws and characteristics of urban transportation.The interrelationships between coordinates are further analyzed according to different stages of urban development and the variation of the development curve, providing valuable insights for urban development strategies.The proposed world urban transportation development coordinate system can be applied globally, serving as a reference for policymakers and experts in formulating comprehensive urban transportation strategic plans.
