Improvements and innovations in urban mobility have greatly expanded individuals’ daily life boundaries. Still, activity patterns and daily life trajectories are found to be closely linked to socioeconomic status, race or ethnicity, and other social identities. Stratification and isolation in individuals’ daily lives occur when different social groups use distinct sets of urban places such that they are rarely exposed to or come into contact with each other. This “daily life segregation” can strengthen existing social divides and exacerbate the effects of segregation in residential neighborhoods, schools and workplace. Moreover, it may limit the access of certain groups to urban amenities or expose them disproportionately to hazards and undesirable environments in their day-to-day usage of urban space. Among the first to probe the consequences of daily life segregation, this study examines how different daily life trajectories expose different social groups to congestion and its related costs. Using large, GPS based mobility and congestion data in Shenzhen, China, we analyze individuals’ daily life trajectories and identify segregation patterns from the lack of co-presence in space-time. The trajectories of segregated groups are then compared to the dynamics and concentration of congestion to estimate the cost of congestion for each group. The study provides new insights to the policy debates on mobility, congestion and urban inequalities, while also shedding light on the significance of daily life segregation research.
