Abstract:: An empirical study is conducted on the planning and design method of cyclist greenway system to improve the quality and travel environment of cyclist greenway in the historic urban areas. Based on the spatial characteristics, the cyclist greenway system in historic urban areas can be divided into units, corridors and nodes. With the help of selforganizing map model,shortest path algorithm, traveling salesman algorithms and cyclist impedance function, a cyclist greenway system planning method is established in the geographical information system based on the empowerment coefficient. The proposed method was applied to conduct an empirical study on the cyclist greenway system of Xi’an. The results indicate that Xi’an can construct a cyclist greenway network with the total length of 142.6 km consisting of 22 cycling corridors. The proposed method can be utilized to construct a cyclist greenway system of the historic urban areas that fitting their travel pattern.Key words: 中图分类号：文献标志码：A文章编号：
