中等规模城市构建公交都市的路径与策略

Strategies of Developing Transit Metropolis for Medium Cities

中等规模城市在空间结构、社会经济发展水平、交通特征等方面与超(特)大城市差异显著,有必要从"公交"和"都市"两个层面剖析中等规模城市构建公交都市的路径与策略。就"公交"而言,提出中等规模城市除步行外公共交通出行分担率的建议统计方法。规划方面应实现常规公共汽车随高客流BRT走向适时调整使其与居民出行需求相适应,提升公共自行车出行环境,优化租赁点布局。就"都市"而言,提出编制BRT沿线的专项控制性详细规划,在商业中心、居住区、历史街区塑造有利于提升公共交通竞争力的空间形态。最后,提出利用互联网技术优化智慧公交服务的具体要求。

As medium cities bear sharp differences with mega cities in spatial structure, socio-economic development level and transportation characteristics, it is necessary to analyze the paths and strategies of developing transit metropolis for medium cities from the perspectives of transit and metropolis. In terms of the former, this paper proposes an alternative statistical method for the mode share of public transit in these cities. In planning, measures should be taken to allow the regular buses to make timely adjustment according to the high passenger flow trend of BRT to meet residents' travel needs, to improve the travelling environment of bike sharing system, and optimize the layout of rental stations. As for the latter, the paper emphasizes the preparation of regulatory detailed planning for the routes along BRT and the formation of spatial form which is helpful to public transit competitiveness in commercial centers, residential areas and historical blocks. Finally, the paper elaborates the requirements for improving intelligent transit services using Internet technologies.
