摘要
以南京地铁1号线为例,充分利用地铁站客流进出数据,运用系统平衡模型与弗雷特法迭代推算得到客流OD矩阵。在系统平衡模型的求解计算过程中,运用数学软件对系数进行求解,提高了系统平衡模型的可操作性。程序设计中引入了相关控制变量,控制OD矩阵的推算精度,提高了算法运算效率。应用统计分析工具对所得数据进行分析,从而得到地铁客流量中的重要统计指标。最后,对南京地铁1号线的时空特性进行了分析。
Using the data of entry-exit passenger at subway stations,this paper intends to estimate the OD matrix of passenger flow with iteration based on the system-equilibrium model and Fraters method. A mathematical software is used to calculate the coefficient in the process of solving the system-equilibrium model, which enhances the model＇s interoperability. The related controlling variables are introduced in the design of the program to improve the calculation accuracy of the OD matrix and raise the efficiency of the algorithm. Finally, based on an analysis of the results with statistical tools, the key statistical indicators of passenger flow at subway station are obtained.
