摘要
为了提高冰雪地区公路弯道处的交通安全水平,从驾驶员弯道认知特性出发,研究驾驶员在冰雪地区公路弯道处的转向行为的影响因素,针对现有的冰雪地区公路弯道驾驶员转向诱导方法的缺陷,进行相关实验.探索并提出基于主动防护的路侧标志组合设计方法,分别就冰雪地区公路条件下弯道诱导标志、减速限速标志和提醒标志的设计及设置位置进行了研究,提出了冰雪道路弯道诱导标设置间距模型,进而得出减速限速和提醒标志设置的最佳位置.
In order to improve the traffic safety level at road corners in snow and ice area,the influencing factors of drivers'turning behavior at road corners in ice and snow areas were studied based on drivers'cognitive characteristics of corners.In view of the defects of the existing steering guidance methods for road drivers in curved roads in ice and snow areas,relevant experiments were carried out This paper explored and put forward a combination design method of roadside signs based on active protection,and studied the design and setting positions of bend guidance signs,deceleration speed limit signs and warning signs respectively under highway conditions in ice and snow areas.A distance model for setting guide signs on ice and snow road curves was proposed,and then the optimal location for setting speed limit and warning signs was obtained.
