摘　　要：对事故多发点进行改造是减少事故的发生、增强交通安全的重要措施。其中增加标志标线等交通安全设施是常见的改造方式。由于驾驶行为是影响交通安全的重要因素,因此有必要从驾驶员角度对改造效进行评价。研究了某二级公路的事故多发点特点。在现场实验的基础上结合驾驶员眼动注视点的特征分析,分别从驾驶员注视特征、运营速度、改造前后的事故分析,综合评价事故多发点的改造效果。同时分析驾驶员负荷特征,为未来事故多发点的安全改造方案提出可行建议。Roadway improvement is one of the most important measures to reduce the accidents at sites with promise, in which adding safety facilities like signs and markings is quite normally applied. Since driving behavior is an important factor that affects the traffic safety, it is necessary to evacuate the true effect from the drivers＇ as- pect. After the study on accident characteristics, combined with the eye movement analysis on the drivers, a com- prehensive evacuation is proposed based on integration of the changes of the drivers＇ gazement, operation speed and crash analysis before and after the improvement. The result has indicated that the effect of sites improvement only using signs has limited influence on the drivers, and this is important to the safety engineering in the future practice.
