摘要
高速公路改扩建对沿线路网交通有很大影响。以乌奎高速公路改扩建工程为例,从分流车型、分流路径和分流节点设置3方面对该高速公路改扩建期间交通分流方案的制定进行分析,并通过计算分流方案实施后分流道路在施工期内的预测交通量来评价和验证分流方案。分析结果表明:根据分流通道剩余承载能力与需分流交通量大小的关系可以合理评价分流方案的适用性。
Reconstruction and extension of expressway may have huge influence on road network traffic along the expressway.Based upon Urumuqi-Kuitun Expressway reconstruction and extension,this paper made analysis to traffic diversion scheme during expressway reconstruction and extension,in 3 aspects of diversion vehicle models,diversion routes and diversion nodes,with calculation to forecast traffic volume of the diversion roads after implementation of the diversion scheme during construction period,the diversion scheme was assessed the verified.Results show that the relationship between the residual capacity of the diversion roads and the traffic volume to be diverted may rationally assess the applicability of the diversion scheme.
