摘　　要：基于现行旅客列车的信息,如列车的编组、定员、径路和上座率等,研究铁路旅客OD矩阵的推算模型和算法。为求出与实际的交通量相匹配的铁路旅客OD流量,利用和铁路运输现场实际工作相吻合的交通配流方法,针对理论分配交通量和实际交通量的偏差程度、采用适时修正的方法进行迭代运算,直至得到一个满意的解为止。In this paper, we study the model and algorithm of railway passenger's OD matrix Estimation, based on actual (passenger) train information, such as: train manifest, fixed number of personnel, route and seat occupancy coefficient etc. For acquiring the railway passenger's OD matrix accord with factual traffic flow, we utilize the method of traffic flow (allocation) suit to railway fieldwork. Being directed against the errors of theory traffic flow and factual traffic flow and make use of error correction to (iteratively) compute, until get a satisfying solution.
