高速公路改扩建工程中交通分流方案研究

Traffic Diversion Scheme of Expressway Capacity Expansion Project

对不同车型的运行特性、施工干扰程度等因素进行分析,拟定分流优先级,利用组合试算法确定分流车型;通过分析不同层次交通的分布特性及对绕行距离的可接受程度,根据通道剩余承载能力和需分流交通量大小的关系,探讨如何确定交通分流方案,研究结论的得出可为高速公路改扩建交通分流方案设计提供理论依据。

Based on analysis of operation characteristics of different vehicle models and construction disturbance degree,this paper puts forward the priority of vehicle diversion and uses combination-test algorithm to determine the diverted vehicles.By analyzing the distribution characteristics and acceptability to bypass roads,it proposes the traffic diversion scheme according to the relation between the surplus channel capacity and diverted traffic volume.It can provide a useful reference for designing traffic diversion program.
