为及时掌握区域公路网运行状况和准确识别瓶颈路段,本文基于可靠度的计算结果,通过点段重要度数据和路网模型分配数据计算,识别出重要路段集,再结合可靠性薄弱数据集,取二者的交集为瓶颈路段。通过算例验证,该方法具有较强的实用性和有效性,也为交通管理者识别和改善路网瓶颈路段通行能力提供依据。

To understand the operation condition of road network in time and identify the bottleneck links in road network more accurately,the points＇ and road section＇ s importance data and the road network model＇s distribution data were calculated,and the important road section set was identified.Then,based on the weak reliability data set,the intersection of the two sets was the bottleneck link.The result of a case study testified the utility and effectiveness of the proposed method,which also could provide an evidence for identifying and improving the capacity of the bottleneck links for traffic management.
