新疆博赛段一级公路限速值合理性研究

Research on rational speed limit on bosai highway in Xinjiang Province

为了研究限速标志设置的合理性,选择新疆赛博段一级公路为调研路段,在限速标志的上下游设置3个断面,检测公路限速区上下游车速,得到分布规律。通过比较实际车速与限速值之间的关系,限速区内与限速区外的速度,以及驾驶员对限速标志的接受程度,判断限速设置的合理性,为决策者了解速度的分布现状,确定合理限速打下基础。最终在保证交通安全的前提下,最大限度发挥道路的使用效率。

Xinjiang Saiguo highway is selected to be the investigated section. Three studies sites are Posited in the vicinity of speed limit sign. By exploring relationship between actual speed and post speed limit inside and outside speed zone, the rationality of post limit sign can be evaluated. The analysis result lays a foundation for post speed determination and also informs decision makers where the speed is most prevalent. It is concluded that on the premise of traffic safety, the PSL should optimize the use of limited road resources.
