我们对空间隔离的大部分了解都集中在人们居住的地方，然而我们关心的许多后果取决于人们在家里以外的地方度过的时间（马修斯，2011; Basta，里士满，& Wiebe，2010; Kwan，2009）。本文通过提出一个新的理论和方法框架来解决这个问题，以理解人们在日常活动中所经过的空间的系统差异-这种现象最好被描述为活动空间隔离（Wong & Shaw，2011）。活动空间隔离是指社会群体在空间和时间上的分离，从社区和城市的空间尺度和小时和天的时间尺度来看。它可以被认为是居住隔离的三维或四维延伸，时间被添加到地理空间的笛卡尔轴。活动空间方法并不把个体看作平面上的点，而是把它们看作随时间延伸的杂乱、不规则的曲线，追踪往返于家园的昼夜节律。通过分析这些曲线的路径，我们可以了解人群之间的互动和障碍，
Most of what we know about spatial segregation centers on where people live, yet many of the consequences we care about depend on where people spend time outside their homes (Matthews, 2011; Basta, Richmond, & Wiebe, 2010; Kwan, 2009). This paper addresses the problem by presenting a new theoretical and methodological framework for understanding systematic differences in the spaces people move through as they go about their daily activities—a phenomenon best described as activity-space segregation (Wong & Shaw, 2011). Activity-space segregation is the separation of social groups in space and time, viewed at the spatial scale of neighborhoods and cities and the temporal scale of hours and days. It can be thought of as a threeor four-dimensional extension of residential segregation, with time added to the Cartesian axes of geographic space. Instead of considering individuals as points on a plane, the activity-space approach treats them as messy, irregular curves that extend over time, tracing circadian rhythms to and from their homes. By analyzing the paths of these curves, we can learn about interaction and barriers between groups of people,
