The objectives of the study are to understand road safety within the context of regional development processes and to assess how urban-rural categories represent differences in motor vehicle occupant fatality risk. We analysed 2015 motor vehicle occupant deaths in Wisconsin from 2010 to 2014, using three definitions of urban-rural continua and negative binomial regression to adjust for population density, travel exposure and the proportion of teen residents. Rural-Urban Commuting Area codes, Beale codes and the Census definition of urban and rural places do not explain differences in urban and rural transportation fatality rates when controlling for population density. Although it is widely believed that rural places are uniquely dangerous for motorised travel, this understanding may be an artefact of inaccurate constructs. Instead, population density is a more helpful way to represent transportation hazards across different types of settlement patterns, including commuter suburbs and exurbs.
本研究旨在理解区域发展进程中的道路安全问题，并评估城乡类别如何体现机动车乘员死亡风险的差异。我们分析了 2010 年至 2014 年威斯康星州的 2015 年机动车乘员死亡事件，使用了三种城乡连续体定义和负二项回归来调整人口密度、出行暴露和青少年居民比例。尽管人们普遍认为农村地区对机动化出行特别危险，但这种理解可能是由于构建不准确造成的。相反，人口密度是一种更有助于代表不同类型的居住模式（包括通勤郊区和远郊）的交通危险的方法。
