论文摘要
最近，住宅隔离已转移到美国的更多阶级或收入，社区正在经历重大变化，例如通勤模式随着时间的流逝。为了更好地了解不同收入水平的社区之间的通勤不平等，这项研究分析了工资组的通勤变异性（距离和时间）以及使用CTPP数据1990-2010在Baton Rouge中随时间推移的稳定性。与以前的工作相比，通过蒙特卡洛模拟各个旅行以减轻聚合误差和规模效应，可以更准确地估计通勤距离。基于邻域平均工资率的结果表明，通勤行为在不同工资率的区域之间有所不同，并且这种可变性是由凸形捕获的。富裕的社区倾向于通勤更多但工资最高的社区，以减少通勤。尽管总体上有整体的运输改善，但随着时间的流逝，这种趋势仍然相对稳定。进行了基于工资组的分布的互补分析，以获得更详细的见解，并发现1990 - 2010年最低工资工人的持久较差的移动性（例如，位置和运输选择较少）。
Residential segregation recently has shifted to more class or income-based in the United States, and neighborhoods are undergoing significant changes such as commuting patterns over time. To better understand the commuting inequality across neighborhoods of different income levels, this research analyzes commuting variability (in both distance and time) across wage groups as well as stability over time using the CTPP data 1990-2010 in Baton Rouge. In comparison to previous work, commuting distance is estimated more accurately by Monte Carlo simulation of individual trips to mitigate aggregation error and scale effect. The results based on neighborhoods mean wage rate indicate that commuting behaviors vary across areas of different wage rates and such variability is captured by a convex shape. Affluent neighborhoods tended to commute more but highest-wage neighborhoods retreated for less commuting. This trend remains relatively stable over time despite an overall transportation improvement in general. A complementary analysis based on the distribution of wage groups is conducted to gain more detailed insights and uncovers the lasting poor mobility (e.g., fewer location and transport options) of the lowest-wage workers in 1990-2010.
