Abstract

In recent decades, transit-oriented development strategies have been widely applied in different countries around the world, including China. There is a mutually promoting relationship between urban land use (activities) and traffic (accessibility) in TODs. However, some TODs cannot achieve this process, which is beneficial to their development. This research evaluated the relationship between accessibility and activities in TODs by applying the SBM model and the super-efficiency SBM model. Hefei City was the case study. The results can identify the TODs whose activities and accessibility cannot promote the development of each other and should be prioritized in future planning. There are two types of priority TODs from the analysis: “Undersupplied TODs” and “Underdeveloped TODs.” In addition, this method can sort TODs according to the efficiency with which it achieves the above relationship. Identifying priority TODs would be helpful for planners to find weak TODs in the TOD network quickly.

合肥市TODs动态性能评价及优先TODs确定
近几十年来,交通导向发展战略在包括中国在内的世界各国得到了广泛应用。在TODs中,城市土地利用(活动)与交通(可达性)之间存在着相互促进的关系。然而,一些tod无法实现这一过程,这对它们的发展是有利的。本文采用SBM模型和超效率SBM模型对tod可达性与活动的关系进行了评价。以合肥市为例。研究结果可以识别出活动与可达性不能相互促进发展的TODs,在未来规划中应优先考虑这些TODs。从分析中可以得出两种优先tod类型:“供应不足的tod”和“未开发的tod”。此外,该方法还可以根据实现上述关系的效率对tod进行排序。确定优先TOD有助于规划人员快速发现TOD网络中的弱TOD。
