Abstract A growing number of studies examine the affordability benefits of living near transit, especially fixed-rail, with the assumption that transportation benefits of transit neighborhoods outweigh increasing housing costs. Yet these studies only compare housing and transportation costs. This study adds to the existing literature by investigating the influence of new light rail on changes in discretionary income in urbanized areas. We examine such changes from 2000 to 2010 at the block group level, comparing light rail neighborhoods (LRNs) and Non-LRNs, across 20 U.S. urban areas that opened light rail stations between this time period. Using descriptive statistical measures and OLS regressions, we find that while discretionary income decreased overall, neighborhoods with light rail provide a positive influence on discretionary income. Overall, our findings suggest light rail neighborhoods provide greater affordability benefits than non-light rail neighborhoods.

剩下什么？轻轨交通对可支配收入的影响

摘要 越来越多的研究检验了在交通附近居住的负担能力优势，尤其是固定铁路，假设公交社区的交通优势超过了不断增加的住房成本。然而，这些研究只比较了住房和交通成本。本研究通过调查新轻轨对城市化地区可支配收入变化的影响，对现有文献进行了补充。我们在街区组级别检查了 2000 年至 2010 年的此类变化，比较了在此期间开设轻轨站的 20 个美国城市地区的轻轨社区 (LRN) 和非 LRN。使用描述性统计措施和 OLS 回归，我们发现虽然可支配收入总体下降，但轻轨社区对可支配收入产生积极影响。全面的，
