公交出行分担率指标探讨

各城市在发展公共交通的过程中出现了不切实际制定发展目标、转换公交出行分担率概念以应付指标检查等问题，同时，由于城市总体规模、形态布局、自然地理等差异，城市之间公交出行分担率指标很难直接对比。借鉴伦敦、巴黎、东京、纽约、香港、新加坡等国际大都市经验，阐述不同口径公交出行分担率的内在涵义和用途。结合公交出行分担率在世界闻名“公交都市”中的实践应用，提出更需要关注特定时段、特定地区、特定目的的公交出行分担率指标，以此制定不同类型城市交通拥堵地区公共交通服务水平改善目标与考核指标。

Discussion on Public Transit Mode Share

The problems of impracticable development targets and creating the misled data in public transit mode share for dealing with the government evaluation are common in different cities during the public transit development. At the same time, it is difficult to directly compare the public transit mode share among cities because of the differences in urban scale, spatial structure and geography characteristics. By learning experience from the international cities such as London, Paris, Tokyo, New York, Hong Kong, and Singapore, this paper discusses the definition and functionalities of public transit mode share under differ-ent statistic scope. Based on the practical usage of public transit mode share in world-renowned“transit-oriented cities”, the paper proposes to pay attention to public transit mode share under specific hours, ar-eas and purposes so that the improved targets for level of service and evaluation indicators for public trans-portation in different urban areas with traffic congestion can be established.
