Abstract：
BACKGROUND: It is essential for drivers employed in the formal sector to have good knowledge of road safety in order to safeguard their lives and those of the staff they are employed to drive. The study was conducted to determine the effect of a road safety education intervention on road safety knowledge of drivers employed in the University of Ibadan, Nigeria.
METHODS: A quasi-experimental study of 98 intervention and 78 control drivers selected using a cluster sampling technique was conducted. The intervention comprised a two-day training on road safety and first aid. The drivers\' knowledge of road safety was measured at baseline, immediately and 4-months post-intervention. Aggregate scores of road safety knowledge were computed giving minimum and maximum obtainable scores of 0 and 16 respectively. Change in mean scores over the three measurement periods was assessed using Repeated Measures Analysis of Variance (ANOVA). Independent t-test was used to compare the scores between intervention and control drivers at each of the assessment periods. Twenty-nine drivers did not complete the study (attrition rate = 16.5%).
RESULTS: At baseline, mean road safety knowledge scores for the intervention and control drivers were 12.7±2.2 and 12.9± 2.3 (p = 0.510) respectively. Immediately and four months post intervention, the scores of the intervention drivers were 13.8±1.9 and 12.8±1.6; while scores for the controls were 13.3±2.0 and 13.2±1.8. Repeated measures ANOVA revealed that the increase in knowledge over the three assessment periods was not statistically significant.
CONCLUSIONS: The intervention resulted in an initial increase in road safety knowledge of the intervention drivers. However, this was not sustained to the forth month post-intervention. This finding suggests periodic refresher trainings to sustain the knowledge acquired.

摘要：
背景：正规部门雇用的驾驶员必须具有良好的道路安全知识，以保护他们的生命以及他们受雇驾驶的工作人员的生命。进行这项研究是为了确定道路安全教育干预对伊巴丹大学雇用的驾驶员的道路安全知识的影响，尼日利亚。
方法：对使用整群抽样技术选择的98个干预和78个对照驾驶员进行了准实验研究。干预包括为期两天的道路安全和急救培训。驾驶员对道路安全的知识是在基线上测量的，立即和干预后4个月。计算道路安全知识的总得分，分别给出0和16的最小和最大可得分数。使用重复测量方差分析(ANOVA)评估三个测量期间的平均得分变化。使用独立t检验来比较干预和对照驾驶员在每个评估期间的得分。29名司机没有完成研究(流失率=16.5%)。
结果：在基线时，干预和控制驾驶员的平均道路安全知识得分分别为12.7±2.2和12.9±2.3（p=0.510）。立即和干预后四个月，干预驾驶员的得分分别为13.8±1.9和12.8±1.6;而对照组的得分分别为13.3±2.0和13.2±1.8.重复测量方差分析显示，在三个评估期内，知识的增加没有统计学意义。
结论：干预措施使干预驾驶员的道路安全知识初步增加。然而,这种情况没有持续到干预后的第四个月。这一发现表明，定期进行进修培训，以维持所获得的知识。
