摘要：借鉴并优化了步行指数的计算方法,测度了中国287座主要城市70余万条街道的步行指数,同时从街道和城市尺度作了步行指数的多维度分析。结果表明,全国街道可步行性较好,但存在极化现象。街道步行指数、功能密度、功能混合度、街道长度及道路交叉口密度等街道属性多呈偏态分布,其中街道功能混合度、交叉路口密度与步行指数具有最大的正相关性。西部城市和东部沿海城市的平均步行指数较华北和西北地区偏高,省会和副省级城市步行指数比地级市和直辖市高。建立步行指数可视化平台,提供步行指数计算结果的街道水平的查询,可供政府及科研人员了解城市街道可步行性及相关指标,并有助于步行系统改善政策和行动的制定。
This research optimizes the ＂Walk Score＂ algorithm from Walkscore.com, which ranges from 0 to 100, and uses it to calculate the walk score for more than 700,000 streets in 287 main cities （at or above prefecture-level） in China. In addition, the research analyzes the walk score at the street level and the city level. The results show that although the walkability is generally good at the country level, it is polarized when it comes to the city level and within the cities. What＇s more, street walk score, function density, function mix and other related factors all have skewed distribution, and the largest positive correlation happens between function mix and junction density. Lastly, western cities and eastern coastal cities have relatively higher average walk scores, comparing to those in the northern and northwestern regions; provincial capitals and sub-provincial cities have relatively higher walk scores in comparison with municipalities and prefecture-level cities. Furthermore, a Walk Score visualization platform was created to provide street-level walk score Iookups. Government officials and scientists can use it to learn about walkability and its related measurements, and hence improve the policy related to the walking system.
