关于城市轨道交通网络的总体研究

General Study on Urban Rail Transit Network

随着我国城市化进程的高速推进和大城市轨道交通的快速发展,轨道交通已经成为城市交通的骨干。由于城市化进程中流动人口增加、工作地与居住地分离,造成交通出行量大且存在较大的不确定性,再加之轨道交通线路潮汐特征明显、客流不均衡系数大,因此许多线路采用传统运营方式运能难以满足客流(尤其是超高峰客流)需求。运营模式必须采用一种更灵活、更高密度的运输组织方式,而高密度运营又需要更稳定、更高可靠性的设备为其提供技术支持。

With urbanization progress rapid advancement and urban rail transit fast development in major cities in China,rail transit has become the backbone of urban transportation.Due to floating population increase and workplace/residence separation in the urbanization process,transportation volume becomes enormous,possessing huge uncertainty.Additionally,rail transit lines exhibit significant peak-hour traffic patterns and passenger flow imbalance coefficient is large.As a result,many lines that adopt conventional operation management mode find it challenging for their transport capacity to meet the transportation demand(especially the super-peak hour passenger flow).A more flexible high-density transportation organization mode is needed for operation,and high-density operation requires more stable and reliable equipment to provide technical support.
