摘　　要：利用双层规划理论建立了多车型高速公路连续平衡网络设计问题的优化模型,将改扩建路段的位置、容量与收费费率的确定纳入一个决策过程,从而建立了高速公路改扩建项目的科学决策方法。上层规划中将路网管理者(政府)作为领导者,经营者的财务目标以及投资上限作为实现系统最优的约束条件;下层规划则在考虑了不同车型道路使用者路径选择的差异性以及增加道路容量对交通分布影响的基础上,建立了多车型多准则用户均衡模型。最后以一个算例对模型的效果进行了验证说明,结果表明:应用该模型可对高速公路改扩建问题进行有效决策。A bi-level programming model for optimization of multi-vehicle-type freeway continuous equilibrium network design was presented to set up a scientific method for road section reconstruction or extension in freeway network which integrated their positions,capacities,and the corresponding network toll rates into one optimal decision-making process.The upper level program model takes the road manager（government） as the leader of the decision-making,and regards the operators＇ financial goals and upper limit of investment as the constraints to achieve optimum system.The lower level program builds multi-vehicle-type multi-criterion user equilibrium model considering the differences in route choice behaviors of different vehicle type users and the effects of road volume extension on the traffic distribution.Finally,a numerical example was presented to illustrate the benefit of this model.The result shows that the proposed model is efficient to make decisions on freeway reconstruction or extension project.
