摘　　要：为提升轨道交通可达性,结合不同形式地面公交的特点,将其用于轨道接驳服务,提出轨道交通、常规公交和需求响应公交的多模式公交线网布局,探究成本最优下的多模式公交线网结构及对应的接驳公交服务模式。模型以公共交通企业成本和乘客出行成本之和最小为目标函数,以轨道交通线路数、常规公交线路数、步行区域大小、轨道交通及两种接驳公交的发车间隔为决策变量,建立多模式公交线网优化模型求解得到最优决策变量取值、系统成本及线网效能。以苏州市为例进行案例研究,结果表明,采用混合接驳方式后公交线路数由633条减少至540条。此外,该系统协同发展三种公交模式,能够有效应对未来城市需求增长和经济发展等情形。To improve the accessibility of rail transit,the paper combines the characteristics of different forms of ground buses and uses them for feeding rail transit.The paper proposes a multi-modal transit network layout of rail transit,conventional buses and demand response buses,and examines the multimodal transit network structure and the corresponding feeder bus service mode under minimum system cost.A multimodal transit network optimization model is established based on the objective function of minimizing the sum of agency cost and user cost.The number of rail transit lines and conventional bus lines,the size of the walking area,and the departure interval of three transit modes are set as decision variables.The results show that the use of hybrid feeder mode effectively reduces the number of bus routes from 633 to 540,and that the system can effectively respond to future urban demand growth and economic development scenarios by developing three modes of transit in coordination.
