城市轨道交通两线换乘形式及便捷性研究

Transfer Efficiency of Urban Rail Transit

通过研究城市轨道交通两线换乘车站站位关系、乘客换乘路径和站台型式组合三大要素,基于综合叠加后形成的换乘形式,对城市轨道交通两线换乘的便捷性进行分析。依据换乘距离计算结果,在不考虑客流分布特征等其他外部因素时,同站台换乘便捷性最高,垂直平行比水平平行便捷性更好;十字型、T型、L型换乘便捷性依次降低,在线路相交时应优先选择十字型;虚T型、虚L型和分离式换乘便捷性较低,主要取决于换乘通道长度。无论采用何种换乘形式,为便于统筹协调资源和提高运作效率,建议换乘车站实行一体化管理,在管理界面、设备设施两个维度做好切分。

Aiming to study transfer efficiency between urban rail transit lines, this paper analyzes the relationship between platform location, the transfer routes of passengers, and different types of platform. The results show that transfer on the same platform is the most efficient type, and vertically paralleled transfer is more effective than horizontally paralleled transfer when excluding external factors, such as passenger flow characteristics. Furthermore, the efficiency degree of cross-shaped, T-shaped and L-shaped transfer decreases gradually, thus cross-shaped transfer is prioritized when the lines intersect. Virtual T-shaped, virtual L-shaped and separating transfer types are less efficient gradually depending on the length of transfer corridor. Therefore, the paper suggests an integrated management over the transfer stations when choosing the transfer type for better coordinating the resources and efficiently operating. Moreover, it is suggested to implement an accurate segmentation between management and facilities.
