基于IC卡信息的公交客流Origin-destination反推方法

公交客流起止点(origin-destination,OD)矩阵是公交线路调整和优化的重要依据,通过公交IC(integrated-circuit)卡信息获得的数据研究了公交出行的特征.以公交站点上下客人数为约束条件提出了综合考虑了公交乘客上下车概率与公交站点产生吸引因素的反推模型,实例分析表明该方法能显著提高反推的精度,反推结果更具可靠性.

Origin-destination Matrix Estimation Method Of Public Transportaion Flow Based On Data From Bus Integrated-circuit Cards

The origin-destination(OD) matrix is the important data for transit line adjusting and optimizing.The public transportation passenger’s travel behavior was researched based on data from integrated-circuit(IC) cards.A public transportation estimating OD matrix model was presented from the passengers’ boarding and alighting probability and production-attraction factors of transit site,with the constraints of the boarding and alighting passenger number.The results of a rigorous validation with data from a real bus route reveal that the proposed model is quite effective and reliable.
