摘要
综合运输网合理规模是区域综合运输规划研究的核心内容之一,也是实现综合运输可持续发展的重要控制指标。在对区域综合运输网结构分析的基础上,扩展了交通网络平衡配流方法,将运输方式选择与配流模型进行整合,形成了"方式-路径"配流模型(MPUE)。以社会总成本最优为上层目标函数,"方式-路径"配流模型为下层规划,建立了综合运输网合理规模确定的双层规划模型,并采用模拟退火优化算法对模型进行求解。最后将模型运用于成渝经济区综合运输网合理规模的计算中,说明模型科学有效。
Reasonable scale of integrated transportation network is one of the core contents of research on regional integrated transportation planning and furthermore it's a key control index to achieve sustainable development of integrated transportation.Based on the structural analysis of regional integrated transportation network,traffic network equilibrium assignment method is expanded,which integrates transport mode choice and assignment model to form "mode-path" assignment model(MPUE,Mode-Path User Equilibrium).In addition,bi-level programming model on reasonable scale of integrated transport network is constructed,whose upper objective function is to realize the optimal social cost and lower objective function is MPUE.And then it's solved by simulating annealing optimization algorithm.At last,the proposed model is applied to the calculation of reasonable scale of integrated transportation network in Chengdu-Chongqing Economic Zone,which proves that the model is scientific and effective.
