采用系统概率抽样法，对全国６ 个铁路局５２ 个机务段１２８０ 名司机（ 按１∶２ 配比，分层随机抽样，事故组３４４ 人，非事故组９３６ 人） ，进行了能力（ 注意力、记忆力） 测评。非事故组注意力明显优于事故组，记忆力２ 组相仿。分层分析表明，内燃机车司机注意力最差，２ 组间差异显著，年龄小、文化高者注意力亦好。研究提示，注意力测试指标比记忆力指标更显重要，年龄与文化是司机行车安全的重要因素。
Using the method of systematic probability sampling, 1280 drivers of 52 locomotive depots in six railway administrations across the country (1: 2 ratio, random stratified sampling, 344 accident teams, and 936 non-accident drivers) , Memory) evaluation. Non-accident group was significantly better than the accident group, similar to the memory group 2. Stratified analysis shows that the drivers of diesel locomotives have the worst attention, the difference between the two groups is significant, and the young people with high culture have the same attention. Research suggests that attention test indicators are more important than memory indicators, and age and culture are important drivers of driving safety.
