摘　　要：以沈山高速公路局域路网为研究对象,首先对局域路网的交通现状进行分析,基于局域路网运营风险饱和度模型,对沈山高速改扩建项目影响区域路网运营风险饱和度进行计算,提出在局部分流中只考虑小流量短时分流,在改扩建交通组织中重点向剩余容量大的路段分流的措施建议。研究成果可为交通量分析预测和施工期交通组织方案提供参考。Taking the local road network of Shenshan expressway as the research object,the traffic status of the local road network is analyzed first.Based on the operational risk saturation model of local road network,the operational risk saturation of road network in the affected area of Shenshan expressway reconstruction and expansion project is calculated.Measures and suggestions are put forward to only consider the short-term diversion of small flow in the local area,and focus on the diversion to sections with large remaining capacity in the reconstruction and expansion traffic organization.The research results can provide reference for traffic volume analysis and prediction as well as traffic organization plans during the construction period.
