摘　　要：部队摩托化机动是一种严密组织、高速流动的特殊交通流,在对其进行微观仿真研究时,需进行部队交通流参数校正,才能提高仿真结果置信度。主要对部队交通流生成模型和部队车辆跟驰模型进行参数校正,提出应用高阶爱尔朗分布拟合部队汽车流车头时距分布,结合部队驾驶行为特性利用SPSA算法对VISSIM中Wiedemann99跟驰模型参数进行校正。最后,以部队在青藏公路上机动为实例,验证校正参数后的仿真模型置信度。Since military motorized mobility is a special well-organized traffic flow with high speed,we should calibrate the traffic flow parameter to improve the confidence of the simulation result. Firstly,the paper mainly calibrates traffic flow generation model and car following model. Then,it calibrates following model parameter of Wiedemann99 with SPSA algorithm according to driving characteristics in army by using Erlang distribution and headway distribution. Finally,it verifies the confidence of the simulation model with mobility on Qinghai-Tibet highway as an example.
