| 摘 要： | 针对现有公路网布局优化模型的目标函数过于偏重机动性的缺点,在公路网布局优化模型中引入了可达性的概念,建立了多目标双层优化模型.上层考虑建设资金的约束,以公路网可达性最大和交通负荷度最小为目标函数;下层与传统的4阶段交通规划模型相结合,采用用户均衡配流模型.为了反映上层模型的两个目标函数之间的trade-off关系,设计了基于Pareto最优的求解算法,并采用进化算法实现.文中提出的方法在北部湾区域公路网布局规划中得以运用.

| Abstract: | A multi-objective bi-level programming model for highway network layout optimization is proposed through involving the concept of accessibility,aiming to improve the traditional single-objective,mobility-oriented approach. The upper-level model consists of two objective functions: maximizing the highway network accessibility and minimizing the traffic load,taking account of the restrictions of construction budget. The lower-level model is the user equilibrium (UE) problem in combination with the traditional... |
