城市空中交通为居民出行提供了新兴的交通选择,垂直起降场等关键基础设施的选址与空间布局将直接影响未来城市居民的出行模式与行为特征。聚焦城市居民的长距离通勤场景,本文基于真实的通勤需求数据,分析了垂直起降场的合理布局。本文构建了一个双层规划模型,模拟垂直起降场的选址与居民出行选择之间的互动机制,旨在寻求能够最小化通勤者单程通勤时间、提升高峰期地面通勤关键道路运行效率的选址方案。在上层,将站点选址构建为一个多目标优化模型,以候选站点的组合为决策变量,采用多目标遗传算法求解;在下层,通过多智能体交通仿真模拟典型通勤者的活动-出行链,评估布局方案对通勤效率的综合影响。以南京市长距离通勤场景为案例,试验结果表明,本文方法能有效提升长距离通勤效率,使整体通勤时间缩短约5%。本文为未来城市多模式交通的规划与管理提供了理论依据与支持。
