Pedestrians comprise 78% of the road fatalities in Peru. The objective of this study was to explore the relationship between the walking environment and pedestrian-motor vehicle collisions.
A matched case-control study was used to detect the odds of a pedestrian-motor vehicle collision at a pedestrian crossing location. Data were collected from 11 sampled police commissaries in Lima, Peru.
In a multivariable model adjusting for vehicle and pedestrian flow, pedestrian collisions were less likely in the presence of a curb and sidewalk on both roadway sides (odds ratio [OR] = 0.19, 95% confidence interval [CI], 0.11-0.33) or a pedestrian barricade (OR = 0.11, 95% CI, 0.01-0.81). There was a greater risk of collisions for each street vendor present (OR = 2.82, 95% CI, 1.59-5.00) or whether any parked vehicles (OR = 3.67, 95% CI, 1.18-11.4) were present.
Improving or addressing these potentially modifiable features of the walking environment could improve pedestrian safety in Lima and in similar urban settings in low- and middle-income countries.
行人在秘鲁的道路死亡人数中占 78%。本研究旨在探讨步行环境与行人和机动车碰撞之间的关系。
采用病例对照研究方法，检测行人横道处发生行人和机动车碰撞的几率。数据来自秘鲁利马的 11 个抽样警察局。
在调整车辆和行人流量的多变量模型中，在道路两侧均设有路缘和人行道（比值比[OR] = 0.19，95%置信区间[CI]，0.11-0.33）或设有行人护栏（OR = 0.11，95%CI，0.01-0.81）的情况下，行人碰撞的可能性较小。每有一个街头小贩（OR = 2.82，95%CI，1.59-5.00）或任何停放的车辆（OR = 3.67，95%CI，1.18-11.4）存在，发生碰撞的风险就会增加。
改善或解决这些步行环境中潜在的可改变特征，可以提高利马和中低收入国家类似城市地区的行人安全。
