轨道交通——多维城市时空中的“虫洞”

Rail Transit——“Wormhole” in Multidimensional Urban Space

文章主要分析了城市空间中时间与空间维度的关系,建立了"时间+空间"的多维时空分析模型,并认为交通条件的差异会导致城市时空的扭曲,而轨道交通就是城市多维时空中的时空隧道——"虫洞"。基于时间空间维度的分析,尤其是对时间维度的关注,能建立更符合人们生活需求的城市模型。而通过降维减少变量的方法,能更简洁、直观地进行相关问题的研究。但基于城市交通可达性的重要性,需要保留时间维度,形成基于多维空间的新的城市空间分析方法。

This paper mainly divides the relationship between time and space dimensions in urban space,and establishes a multidimensional space-time analysis model of"time+space".It is believed that the difference in traffic conditions will lead to the distortion of urban space and time,and rail transit is the time-space tunnel of the city’s multi-dimensional space-time-"wormhole".The author believes that the analysis based on the dimension of time and space,especially the attention to the time dimension,can establish a city model that is more in line with people’s life needs.The method of reducing variables by dimension reduction can make the research of related issues more concise and intuitive.However,based on the importance of urban transport accessibility,we must preserve the time dimension and form a new urban spatial analysis method based on multidimensional space.
