摘　　要：公交网络客流OD是公交线路规划和调整的重要依据。直接进行OD调查过程复杂,且数据精准度受抽样率影响较大。传统模型忽略公交换乘和道路拥堵对OD推算路径的影响,推算结果不理想。根据公交站点上下客流数据,提出以公交网络阻抗为基础,建立广义最小二乘法和交通分配相结合的双层优化模型,考虑公交换乘和道路拥堵对OD推算路径的影响,设计相应的收敛计算规则,并运用实际案例对模型进行验证。与实际调查数据进行对比的结果证明该公交客流OD推算模型具有较高的精度。. The OD matrix is the important data for transit line planning and optimizing. The process of OD investigation is complex and the accuracy is influenced by the sample rate. Results of traditional models are not satisfactory,which ignore the impact of bus transfer and road congestion estimated to OD paths. This paper presents an efficient OD estimation bi-level model,which applies the impedance of bus travel using the number of boarding and alighting passengers at each stop. This paper details the key issues associated with the model including design of the impedance parameters, the calibration of model parameters, and rule of convergence. The results of a rigorous validation with data from a real bus network reveal that the proposed model is effective and reliable.
