Abstract

Foster road safety in school surroundings is an answer for high traffic injury rates and can help to build safe, healthy, and sustainable cities. This paper pursues two goals: identifying the built environment characteristics that influence the severity of traffic crashes in elementary school surroundings for a medium-sized city in Latin America, Porto Alegre (Brazil); and discussing safety measures to provide information for policy making. Ordered and unordered discrete choice models, with random parameters, were estimated in order to analyze the influence of built environment characteristics on the traffic crash severity. The modeling indicates that the severity of traffic injuries in school surroundings is influenced by school, crash, socioeconomic characteristics, and the built environment, highlighting the negative role of the number of four-way intersections and the positive impact of commercial land use for crash involving a car and at least one pedestrian or cyclist. Developing built environment strategies to encourage active mode trips should consider identifying measures to ensure safety.

学校周边的建筑环境与撞车严重程度：巴西阿雷格里港研究

加强学校周边的道路安全是解决高交通伤害率的一个办法，有助于建设安全、健康和可持续发展的城市。本文有两个目标：确定影响拉丁美洲中型城市阿雷格里港（巴西）小学周边交通事故严重程度的建筑环境特征；讨论安全措施，为政策制定提供信息。为了分析建筑环境特征对交通事故严重程度的影响，我们估算了带有随机参数的有序和无序离散选择模型。建模结果表明，学校周边交通伤害的严重程度受学校、交通事故、社会经济特征和建筑环境的影响，突出了四向交叉口数量的负面作用，以及商业用地对涉及汽车和至少一名行人或骑自行车者的交通事故的正面影响。在制定鼓励积极出行方式的建筑环境战略时，应考虑确定确保安全的措施。
