公交线路客流OD矩阵推算方法研究

Study on OD Matrix Estimation of Transit Passenger Flows

公交线路客流OD矩阵是公共交通管理和控制不可缺少的信息。参照机动车OD矩阵反推技术,对公交线路客流OD矩阵推算进行了专门研究。在公交线路客流OD调查数据的基础上,分析得到居民公交出行规律。首次建立了根据公交乘客上下车人数推算公交线路客流OD矩阵的极大熵模型,分别采用原始资料作为先验OD和重力模型形式的先验OD对模型进行求解,结果证明该模型精度较高。

According to OD matrix estimation of vehicle, OD matrix estimation of transit passenger flow was thoroughly studied. On the basis of the surveyed OD matrix data of transit passenger flow, the residents＇ transit trip rule was drawn. Maximum entropy model developed based on boarding and alighting counts was adapted to OD matrix estimation of transit passenger flow for the first time. The solutions of the model were derived using a given OD matrix as original data and gravity model respectively. The result proved that the model was accurate enough.
