Segregation often dismantles common activity spaces and isolates people of different backgrounds, leading to irreconcilable inequalities that disfavour the poor and minorities and intensifies societal fragmentation. Therefore, segregation has become an increasing concern and topic of research with studies typically concentrating on the residential communities of a particular racial or socioeconomic group. This paper enhances the residential view of segregation and examines the topic in the context of urban mobility. Specifically, it expands upon prior research by employing large-sample, seamless telecommunication logs of London, UK to provide a holistic view of mobility across the entire socioeconomic spectrum. A method is developed to transform the data to flows between geographic areas with different socioeconomic statuses. Spatial interaction models are then calibrated to examine the impact of both geographical distance and socioeconomic distance on the deterrence of flows and the analysis is extended to analyze the interaction of the two factors. Overall, socioeconomic distance is found to have a subtle effect compared to geographical distance. However, different effects are observed depending on the socioeconomic distance between flows and the deterrence of mobility tends to be the greatest when both physical and socioeconomic distance are high, suggesting that both factors may play a role creating and maintaining segregation.

种族隔离经常破坏共同的活动空间，使不同背景的人隔离，导致不可调和的不平等现象，不利于穷人和少数民族，加剧了社会分化。因此，隔离已经成为越来越多的关注和研究主题，研究通常集中于特定种族或社会经济群体的居住社区。本文增强了居民对隔离的看法，并在城市流动性的背景下研究了这一主题。具体而言，它通过采用英国伦敦的大样本无缝电信日志来扩展先前的研究，以提供整个社会经济范围内流动性的整体视图。开发了一种将数据转换为具有不同社会经济地位的地理区域之间的流的方法。然后对空间相互作用模型进行校准，以检查地理距离和社会经济距离对流量威慑的影响，并扩展分析以分析这两个因素的相互作用。总体而言，发现社会经济距离与地理距离相比具有微妙的影响。但是，根据流量之间的社会经济距离观察到不同的影响，并且当物理距离和社会经济距离都很高时，流动性的威慑力往往最大，这表明这两个因素都可能在建立和维持种族隔离中发挥作用。与地理距离相比，发现社会经济距离具有微妙的影响。但是，根据流量之间的社会经济距离观察到不同的影响，并且当物理距离和社会经济距离都很高时，流动性的威慑力往往最大，这表明这两个因素都可能在建立和维持种族隔离中发挥作用。与地理距离相比，发现社会经济距离具有微妙的影响。但是，根据流量之间的社会经济距离观察到不同的影响，并且当物理距离和社会经济距离都很高时，流动性的威慑力往往最大，这表明这两个因素都可能在建立和维持种族隔离中发挥作用。
