Many cities have undergone spatial redistributions of low-income populations from central to suburban neighborhoods over the past several decades. A potential negative impact of these trends is that low-income populations are concentrating in more automobile-oriented areas, resulting in increased barriers to daily travel and activity participation, particularly for those who are unable to afford a private vehicle. Accordingly, the objective of this article is to analyze the links between increasing sociospatial inequalities, transport disadvantage, and adverse travel behavior outcomes. This is examined first from a theoretical perspective and second via a spatiotemporal analysis for the Toronto region from 1991 to 2016. Findings show that many suburban areas in Toronto are not only declining in socioeconomic status but are also suffering from increased barriers to daily travel evidenced by longer commute times and decreasing activity participation rates, relative to central neighborhoods. Because of these adverse effects, this evidence further supports the need for progressive planning and policy aimed at curbing continuing trends of suburbanization of poverty while also improving levels of transport accessibility in the suburbs.

在过去的几十年里，许多城市经历了从中心到郊区的低收入人口的空间重新分布。这些趋势的潜在负面影响是低收入人口正集中在更多以汽车为导向的地区，导致日常出行和参与活动的障碍增加，特别是对于那些买不起私家车的人。因此，本文的目的是分析日益加剧的社会空间不平等、交通劣势和不利的旅行行为结果之间的联系。首先从理论角度对此进行研究，然后通过对多伦多地区 1991 年至 2016 年的时空分析进行研究。调查结果表明，与中心社区相比，多伦多的许多郊区不仅社会经济地位下降，而且日常出行的障碍也越来越多，通勤时间延长和活动参与率下降都证明了这一点。由于这些不利影响，这一证据进一步支持了渐进式规划和政策的必要性，旨在遏制贫困郊区化的持续趋势，同时提高郊区的交通可达性水平。
