轨道交通枢纽换乘效率评价指标构建

Construction of Evaluation Index for Rail Transit Hub Transfer Efficiency

换乘枢纽是影响现代城市轨道交通线网效率的重要因素之一,在讨论影响换乘效果因素基础上,对枢纽换乘效率进行分析,给出乘客在换乘枢纽内的平均换乘时间、换乘路径客流量、平均走行距离等换乘有效性指标的计算方法。结合枢纽站内拥挤度、舒适度和安全性等指标,从有效性和顺畅性等方面构建评价指标体系。通过对评价指标体系中单项指标计算,表明构建的评价指标更具有科学性和完整性,将换乘枢纽作为一个整体,突出客流特征的数学模型可达到全局最优。

Transfer hub is one of the important factors affecting rail transit network efficiency in modem city. After discus- sing the influencing factors of transfer effect, the paper analyzes the hub transfer efficiency, and provides methods for calcu- lating transfer validity index of passengers＇ average transfer time, passenger volume and average walking distance in trans- fer hub. Combining with the index of congestion, comfort and safety in transfer hub, it also constructs an evaluation index system considering the validity and smoothness. The calculation result of the single index in this evaluation index system shows that the evaluation index which highlights the mathematical model is more scientific and perfect, and it takes the transfer hub as a whole to reach the global optimum.
