中文摘要： 驾驶行为建模一直是道路交通领域研究的核心问题之一，在交通仿真、交通安全等领域有着广泛的应用价值。针对以往研究中忽视驾驶员视觉感知特性、缺乏对综合驾驶行为决策机制研究的问题，本项目结合交通工程学与认知心理学相关理论，以驾驶员视觉角信息感知、处理与决策过程为核心，研究基于视觉角及其衍生变量的视觉感知过程、多客体共同作用下的视觉角信息处理机制以及复杂交通环境下的驾驶行为多目标决策过程，揭示驾驶员视觉角信息感知与处理的本质，提出基于视觉角的驾驶行为建模框架。在此基础上分别研究多视觉角信息输入条件下的跟驰模型与换道模型，形成综合驾驶行为的信息处理机制与行为决策逻辑规则体系，建立综合驾驶行为模型。通过问卷调查、数据实测、驾驶模拟器等手段标定模型关键参数，结合宏微观方法验证模型有效性。本研究提出综合驾驶行为建模的新思路与新方法，为复杂环境下交通仿真、综合驾驶行为分析、智能驾驶策略设计等提供理论依据。

英文摘要： Driving behavior model, which can be widely applied in traffic simulation and traffic safety, has been one of most important topics in the road traffic flow area. The previous studies ignored the characteristics of diver's visual perception and lacked the decision-making mechanism of the integrated driving behavior. Thus, this project will combine with traffic engineering and cognitive psychology theory for driving behavior modeling. Firstly, based on the core process of driver's visual angle perception, processing, and decision-making, we will study the perception process using visual angle and its related variables. Secondly, we will propose a visual angle processing mechanism with consideration of multi-object information, and a multi-objective decision-making process in a complex traffic environment. Then, the nature of perception and processing of the driver's visual angle will be revealed, and the driving behavior modeling framework based on visual angle will be presented. After that, car following models and lane changing models will be studied considering the inputs of multi-visual angle information, information processing mechanisms and behavioral decision-making logic rules of the integrated driving behavior, and the integrated driving behavior model will be established. Lastly, we will calibrate the k
