摘要
为解决穿村镇公路由于警告标志设置不当而造成的交通安全问题,以北京琉辛路密云县不老屯路段为例,根据驾驶员离散驾驶行为理论和心生理特性,研究穿村镇公路警告标志的前置距离,获得在限速60 km/h的穿村镇公路上,预告需要采取停车措施通过危险地点的警告标志的前置距离应在70~90 m之间的结论,并利用模拟驾驶实验测得驾驶员的心生理数据加以验证。认为细化警告标志的设置位置可以更加有效地指导驾驶员的驾驶,避免因为信息遗漏和误导造成的驾驶误操作,为穿村镇公路交通安全提供了有力保障。
In order to investigate the problem of traffic safety on highways through towns and villages due to the incorrect settings of warning signs,a case study is implemented at a section of Liuxin Road going through the Town of Bulaotun,Miyun District,Beijing.Based on related theory about drivers＇ behavior and their psychological/physiological characteristics,appropriate lead distances of warning signs on highways going through towns and villages are studied.It is found out that such lead distances should be between 70 and 90 meters based on the speed limit of 60 km/h for such highways.The above lead distances are also verified by the drivers＇ psychological and physiological data measured from a simulated driving test.The refinement of the locations of warning signs is considered to be an effective way to guide the driving process by eliminating wrong operations due to misleading information,and thus improve traffic safety on the highways going through towns/villages.
