Access Across America: Bike 2019 Data

These data were created as part of a study that examined the accessibility to jobs by bicycling in the 50 largest (by population) metropolitan areas in the United States. It is the most detailed evaluation to date of access to jobs by biking, and incorporates a Level of Traffic Stress analysis to allow calculation of access to jobs on bike networks of different traffic stress tolerances. This dataset allows for a direct comparison of the biking accessibility performance of America's largest metropolitan areas. These data are part of a longitudinal study.

本数据集源自一项针对美国按人口规模排序前50的大都市区骑行通勤可达性的研究。这是目前为止针对骑行通勤可达性开展的最精细化评估，其纳入了交通压力等级（Level of Traffic Stress）分析框架，可用于计算不同交通压力耐受度下的骑行路网通勤可达性。本数据集可实现美国各大都市区骑行通勤可达性表现的直接对比，且属于一项纵向研究的组成部分。
