城市轨道交通近期建设时序是轨道交通项目建设的依据,可避免建设的盲目性。简要分析了近期建设时序的总体框架及其意义,从近期建设时机和年限、近期建设规模、近期建设线路三个方面详细论述了确定近期建设时序的方法。首先分析了选择近期建设时机的影响因素。然后,考虑近期城市交通承载能力以及建设资金的控制,提出利用交通需求法和建设资金控制法确定轨道交通近期建设的合理规模。最后,建立以最大综合效益为目标的近期建设线路安排优化模型,给出模型的假设条件、约束条件及求解方法。
The recent construction schedule of urban rail transit is the basis for the construction of rail transit projects, which can avoid the blindness of construction. This paper briefly analyzes the general framework of the recent construction sequence and its significance. It discusses in detail the methods of determining the construction sequence in the near future based on the recent construction time and date, the recent construction scale and the recent construction routes. First of all, it analyzes the factors that affect the timing of the recent construction. Then, considering the recent urban traffic carrying capacity and the control of construction funds, this paper proposes to use the traffic demand method and the construction fund control method to determine the reasonable scale of the recent construction of rail transit. Finally, the optimization model of the recent construction route with the maximum overall benefit is established, and the assumptions, constraints and solutions of the model are given.
