时空间视角下的轨道交通地下空间研究——以日本大型轨道交通站地下步行系统为例

Study on Underground Space in Front of Rail Transit Station Based on Pedestrians' Spatio-Temporal Distribution:The Case of Underground Pedestrian System of Large Railway Station in Japan

以大型轨道交通站前区域为例,通过介绍地下步行系统发展趋势,探讨时空间视角下地下空间研究涌现的问题,提出不同时间尺度下"步行者-步行空间"的动态空间关系模型,探索基于时空间行为调查的地下步行空间时空行为研究框架。以地下街为例,介绍基于路段交通量的步行者时空间分布的推定方法,展望时空间分布数据在地下步行空间评价中的应用前景。时空间行为研究拓展了步行空间评价的时间尺度,增强了地下空间设计、规划工作的科学性与前瞻性,对改善地下空间环境具有重要的意义。

This paper introduces the research issues on underground space in the viewpoint of spatio-temporal distribution study, and proposes a dynamic spatial relation model between people and underground space in view of the influence of time factor, A framework of space-time behavior research is explored based on people＇s spatio-temporal distribution data. With the case of an underground shopping street, the paper proposes the methods of estimating pedestrians＇ spatio- temporal distribution and evaluating the service level of underground pedestrian space. Space- time behavior study aims to expand the spatial/time range of pedestrian space evaluation and make underground space design/planning prospective. It is expected to provide references for improving the environment of underground space.
