【摘要】 开发了一款基于蒙特卡罗方法的网络可靠度分析程序(RANMGG),并较为详细地探讨了交通规划技术评价阶段各路段、节点单元的单元可靠度的取值方法.在上述工作的基础上,对郑州市某区域城市道路的瓶颈路段、节点等进行了定性和定量的分析评价.通过与该地区实际情况的比较分析,验证了本文方法的合理性,进而可以为郑州市道路网络的改、扩建决策提供具体的建设性意见.更多还原

【Abstract】 A program of network reliability analysis based on Monte-Carlo was developed and studied in detail to assess the traffic planning stage of the unit reliability in the road-network phase and the transport phase.Based on the work,qualitative and quantitative assessment in a region of Zhengzhou city was done to locate the bottleneck road segments and nodes.Comparing with the practical situation of the area,the rationality of the suggested method was proved.And some constructive suggestions have been proposed for the planning,reconstructing and extending of the local road network of Zhengzhou city.更多还原
