This study examined vehicle rollovers in terms of site-specific exposure and speeds of vehicles of varying stability.
Fifty-one rollover sites in two states were visited at the same time of day and day of week as the rollover. A sample of vehicles moving in the same direction as the rollover were observed, and vehicle-specific data were obtained from identification numbers.
Low stability, exacerbated by the addition of passengers, increased the risk of rollover. Speed was not correlated with stability and is not a confounder.
Rollovers could be substantially reduced if motor vehicles were manufactured with a static stability of 1.2 or greater.
本研究从特定地点暴露情况和不同稳定性车辆的速度方面对车辆翻车事故进行了调查。
在翻车事故发生的同一天的同一时间以及同一星期的同一天，对两个州的51个翻车地点进行了走访。观察了与翻车车辆同向行驶的车辆样本，并从识别号码中获取了特定车辆的数据。
稳定性低，再加上乘客增加，会增加翻车风险。速度与稳定性无关，也不是一个混杂因素。
如果机动车制造时的静态稳定性达到1.2或更高，翻车事故可能会大幅减少。
