在东京，夏季公共空间过热是一个具有挑战性的问题，需要解决这个城市充满活力的社会生活才能持续。东京的城市化是基于公交导向的发展（TOD）;本研究的重点是了解城市热岛效应（UHI）和公共空间之间的相关性，并提供解决方案，以减轻这些空间的过热。将30个公共空间的现场小气候数据与平均每日天气预报数据进行比较，以确定过热水平。然后分析选定地区的空间结构，以确定可能导致过热的规划问题。过热程度高的公共空间往往缺乏植被，而且面积小，干燥，无法阻挡风流。没有过热的公共空间往往是宽阔的、绿色的和阴凉的。这些空间的小气候与每日天气预报相似。这些研究结果被用于制定新的规划指导方针，以改善TOD，制定公共空间过热缓解策略，并确定城市结构可持续改善的未来方向。
In Tokyo, the overheating of public spaces in summer is a challenging issue that needs to be resolved for the vibrant social life in this city to be sustained. The urbanisation of Tokyo is based on transit-oriented developments (TODs); this study focused on understanding the correlation between the urban heat island (UHI) effect and public spaces within TODs and on providing solutions for mitigating the overheating of such spaces. The onsite microclimatic data of 30 public spaces near transit nodes were compared with average daily weather forecast data to identify the overheating levels. The spatial structures of the selected areas were then analysed to identify possible planning issues that led to the overheating. Public spaces with high-overheating levels tended to have a lack of vegetation and to be small, dry, and blocked from the wind flow. Public spaces that were not overheated tended to be wide, green, and shaded. These spaces had a microclimate similar to the daily weather forecast. These findings were used to develop new planning guidelines for improving TODs, developing overheating mitigation strategies for public spaces, and identifying future directions for sustainable improvement of the urban structure.
