摘　　要：由于OD矩阵在路网中的表现就是路段流量,据此,本文将基于用户平衡分配流的双层规划模型简化成单层规划模型.文章构造出一个把路段流量与实测的路段流量之间的偏差平方和最小作为目标函数的单层规划模型及其求解算法.新的算法考虑了交通数据中的不确定性因素,将反推的路段流量和实测的路段流量控制在一个允许的偏差范围内,这样推导出来的OD矩阵精确度更高,更符合实际.Because OD （Origin - Destination） Matrix in the performance of the network is the road traffic, the bi -level programming based on the user equilibrium is simplified in this paper into the single - level program- ming, which takes minimizing the sum of deviation square between the observed link flows and estimated link flows as the objective function and finds the solution algorithm. Thanks to its consideration of uncertain factors of the traffic data, the algorithm controls the deviation between the observed link flows and estimated link flows in an allowing bound, which makes OD matrix estimation more accurate with more conformity to reality.
