| 摘 要： | 交通网络建设序列优化是交通规划中一个重要问题。文章对交通网络设计及其建设序列问题的研究现状进行了分析。按照网络建设中规划者和用户间的关系,以交通网络建设序列下的各阶段系统总费用作为上层规划,以各阶段的交通流用户平衡模型作为下层规划,建立了双层规划模型。并依照问题的特点,采用动态规划的求解方法进行探讨,而下层模型则采用了基于路径搜索的GP算法进行求解。并针对网络规划算例进行了计算,针对固定和变动客流OD两种情况下的结果进行了分析。计算的结果表明,问题的双层规划模型和动态规划求解算法能够为路网规划决策提供支持。

| Abstract: | The item order optimal design is a very important problem in transportation planning.In this paper,the transportation network design problem is analyzed,especially about its item order optimal problem.According to the relationship between the designer and the users in the network design process,taking the total cost of every design item phase of network system as the upper model and the traffic flow user equilibrium of every phase as the lower model,the bi-level programming model is constructed.Considering ... |
