Road-rail crossings where a train and motor vehicle crashed were compared with the next crossing in the direction from which the train traveled at the same time of day and day of week of the crash. The odds of a crash were much lower at crossings with automatically lowered gates (odds ratio = 0.11). Average road traffic was much higher at crash sites; the presence of automatic gates was unrelated to the volume of road traffic. Federally funded modifications of road-rail crossings have substantially reduced deaths at such sites. The program would be more cost effective, however, if criteria for highest risk sites were applied more systematically, and funds were apportioned among the States according to their relative proportions of the problem.
将火车与机动车相撞地点的公路铁路平交道口，与火车在事故发生当天的同一时间、同一星期几行驶方向上的下一个道口进行了比较。设有自动降下门的道口发生碰撞的几率要低得多（优势比=0.11）。事故现场的平均道路交通量要高得多；自动门的设置与道路交通量无关。联邦政府资助的公路铁路平交道口改造大大减少了此类地点的死亡人数。然而，如果更系统地应用最高风险地点的标准，并根据各州问题的相对比例在各州之间分配资金，该计划将更具成本效益。
