| 摘要: |
| 为研究占道施工事件对区域路网络容量的影响,基于双层规划理论,构建了考虑路段通行能力约束的区域路网络容量计算模型,并设计了求解算法。通过VISSIM仿真软件,确定了施工区段通行能力基准值,对实际通行能力与各影响因素之间的定量关系进行分析,给出了占道施工条件下实际通行能力计算方法。结合交通流分配结果、边介值、蓄意破坏前后路网效率变化率给出了占道施工期区域关键路段识别方法。最后以哈尔滨市阿城区的路网为案例,通过手机信令数据获取得到出行需求分布,计算占道施工前后的路网容量,并对占道施工期阿城区路网进行了重要度排序。研究表明:初始条件下区域路网络容量为38 445 pcu/h,施工时为36 865 pcu/h,路网络容量值减少了4.1%。 |

| Abstract: |
| In order to study the impact of road occupation construction events on the capacity of regional road network, based on the theory of bilevel programming, a calculation model of regional road network capacity considering the capacity constraints of road sections is constructed, and the solution algorithm is designed. Through VISSIM simulation software, the capacity benchmark value of the construction section is determined, the quantitative relationship between possible capacity and various influencing factors is analyzed, and the calculation method of possible capacity under the road occupation construction condition is given. Combined with the traffic flow distribution results, the boundary value, and the change rate of road network efficiency before and after deliberate destruction, the identification method of key sections in the occupied road construction period is given. Finally, taking the urban road network in Acheng District of Harbin City as a case, the travel demand distribution is obtained through the acquisition of mobile phone signaling data, the road network capacity before and after the road occupation construction is calculated, and the importance of the road network in Acheng District during the road occupation construction period is ranked. The research shows that the capacity of regional road network is 38 445 pcu/h under initial conditions and 36 865 pcu/h during construction, which reduces capacity of road network by 4.1%. |
