To analyze the motives for using and not using pedestrian bridges (PB).
A cross-sectional survey was conducted of a sample of pedestrian users and non-users of PB; a logistic regression model was used to analyze the motives for use and non-use.
The prevalence of non-use was 50.5 % of 813 surveyed pedestrians; the principal reason to use a PB was safety, and not to use it was "laziness". There were significant differences when analyzing the reason of non-use in the age groups 19 to 36 years, adjusted for education and physical characteristics of the PB ([aOR=1.7; 95 % CI=1.06-2.86] and [ORa.1.9; 95 % CI=1.14-3.33], respectively).
The results of this study allow us to identify important aspects to consider--from the perspective of the pedestrians--when constructing new PB and improving existing PB to increase use in areas with a high risk of pedestrian injuries.
分析使用和不使用人行天桥（PB）的动机。
对人行天桥的使用者和非使用者样本进行横断面调查；采用逻辑回归模型分析使用和不使用的动机。
在813名接受调查的行人中，不使用的比例为50.5%；使用人行天桥的主要原因是安全，不使用的主要原因是“懒惰”。在分析19至36岁年龄组不使用的原因时，经教育程度和人行天桥物理特征调整后存在显著差异（分别为[aOR=1.7；95%CI=1.06-2.86]和[ORa=1.9；95%CI=1.14-3.33]）。
本研究结果使我们能够确定在新建人行天桥和改善现有天桥以增加行人受伤风险高的地区的使用率时，从行人角度应考虑的重要方面。
