交通热点问题的规划思考

针对当前城市交通发展过程中被广泛关注的公共交通出行分担率实际应用问题、城市交通缓解拥堵措施问题,以及共享单车出现引发的道路空间划分问题开展研究。提出如下观点和结论:一是科学应用公共交通出行分担率指标,不应将其作为短期公共交通发展水平评价的统计指标,也不应为了大规模建设轨道交通而提出过高的公共交通出行分担率目标;二是对于城市拥堵状态应有理智的认识,缓解拥堵不是无限增加道路网密度、无限提高车速,而是使道路能够有序地运行;三是对于新兴的共享单车,在鼓励发展的同时,应深入研究非机动车通行和停车管理问题、逐步实施道路的空间划分。

Thoughts on Handling Hot Issues in Transportation

This paper presents the views and advices on how to handle several hot issues in urban transpor-tation development such as the promoting transit travel mode share, urban traffic congestion measures, and the right-of-way allocation considering the emergence of bike sharing. First, the indicator of transit travel mode share should be recognized as neither a short term statistical indicator in assessing the level of public transit development nor an over ambitious goal of transit travel mode share for the sake of massive con-struction of rail transit. Secondly, having a rational understanding on how to reduce urban traffic conges-tion is important since the alleviating traffic congestion cannot come from unlimited roadway network con-struction and aimlessly to enhance operating speed. Reducing congestion is to make roadways operate or-derly. Thirdly, while encouraging the bike share development, it is important to study the non-motorized ve-hicles' operation and parking management problem in order to gradually materialize the proper right-of-way allocation for all travel modes.
