摘　　要：微观交通仿真模型在交通系统管理、控制和优化中得到广泛应用 ,然而大多数仿真模型参数均是针对外国的交通情况确定的 ,并不一定适合中国国情。文章提出了微观仿真模型参数校正流程 ,以上海市北京东路VISSIM仿真为实例 ,根据实际采集的数据 ,运用拉丁方格法进行实验设计 ,对VISSIM的仿真参数进行了校正 ,指出了微观仿真模型参数校正有待改进的方面。Microscopic simulation models have been widely used in traffic system management, control and optimization; however, most of the simulation parameters are determined according to the situations in foreign countries and not always suitable for those in China. Firstly, this paper proposes a procedure for microscopic simulation model calibration. Then taking a VISSIM simulation example of Peking road in Shanghai as an example, we have designed the experiment by using Latin Square algorithm and calibrated the simulation parameters by using the field data. Finally, it points out the aspects that need improving.
