改善城市地区的营养需要了解哪些社区和人群无法进入销售水果和蔬菜等健康食品的商店。为此，最近的工作重点是绘制无法进入超市等场所的地区，通常将其称为“食物沙漠”。直到最近，这项工作还没有考虑到交通系统促进居民的流动性，即使在那些这样做的人中，也很少有人考虑到其他交通形式，如公共交通，选择以汽车为导向的出行假设。本文分析了人们进入超市的时空约束，重点研究了公交通勤人群。对俄亥俄州辛辛那提通勤数据的分析显示，与离开家的情况相比，当在下班回家的路上进行杂货店购物时，有相当数量的居民改善了进入超市的机会。这些结果扩展了以前的工作，显示相对较少的汽车通勤居民有更好的访问超市鉴于他们的工作地点。
Improving nutrition in urban regions involves understanding which neighborhoods and populations lack access to stores that sell healthy foods, such as fruits and vegetables. To this end, recent work has focused on mapping regions without access to places like supermarkets, often terming them ‘food deserts’. Until recently, this work has not considered residents’ mobility as facilitated by transportation systems, and even among those that do, few have considered alternative forms of transportation, like public transit, opting for automobile-oriented travel assumptions. This paper analyzes people’s spatio-temporal constraints to accessing supermarkets, and focuses on the transit commuting population. Analysis of commute data from Cincinnati, Ohio shows there are a significant number of residents that have improved access to supermarkets when a grocery shopping trip is made on the way home from work, than if they were to depart from their home location. These results extend previous work showing relatively few automobile commuting residents have better access to supermarkets given their work locations.
