摘　　要：为准确刻画交叉口机非交互行为、准确模拟右转机动车轨迹,在充分考虑非机动车群组特征和右转机动车驾驶人动态多步决策特征的基础上,基于认知过程建立驾驶人环境感知-规划决策-控制执行的行为模型,并通过改进社会力模型进行仿真实现与模型评价.研究成果可为二维仿真平台的构建和自动驾驶汽车的拟人化驾驶提供模型支撑.In order to precisely describe the interactions and develop accurate simulation models, an analysis was made of the characteristics of bicycle group and the dynamic multistep decision process of drivers, based on which a three-layer modeling framework consisting of drivers' perception, decision making and action were proposed, and a modified social force model was used for simulation and model evaluation. The results can give further support to build a more reliable microscopic simulation platform and provide ideas for autonomous vehicles.
