基于IC卡数据估计交通小区的公交OD算法

公交客流OD是公交线网优化、评估的基础数据;也是公交运营管理不可或缺的重要信息,而公交站点OD是区域公交OD客流的基本单元。在分析利用IC卡数据挖掘公交站点OD客流原理的基础上,梳理公交站点OD推算小区OD的影响因素,引入公交站点至小区之间的距离权重系数以及地块用地分配权重系数,构建了公交站点OD推算交通小区OD的模型算法;并对比分析不同参数构建模型的优劣。同时,以广州市为例进行实证研究,算例表明了模型的可行性和算法的有效性。

An OD Matrix Estimating Algorithm of the Traffic Zone Based on Intelligent Cards Data

Passenger origin-destination matrix(OD) data is not only the basic of the bus network optimization and evaluation, but also the significant information of the bus operation and management. Meanwhile, bus station OD is the basic unit of the traffic zone OD. Firstly, bus station OD were analyzed based on bus IC cards and automatic vehicle location (AVL) data, and impact factors were proposed from bus station OD to traffic zone OD. Secondly, distance weight coefficient and land use distribution weight coefficient were used, and model algorithm were built, and advantages and shortcomings of were the mode algorithm compared. Finally, A case study of Guangzhou was studied. The results show that the model is effective and feasible.
