| 摘 要： | 应用分子动力学研究了车辆跟驰特性,探索了车辆跟驰的需求安全距离及其应用模型构建。通过赋予跟驰模型多个刺激项的反应权重,运用数学演绎方法,推导出驾驶员对各种刺激反应同向性的状态方程。在此基础上提出了描述跟驰变化过程的分子跟驰模型。数据验证和试验对比分析结果表明,分子跟驰模型对跟驰状态的描述更加全面和贴切,弥补了速度跟驰模型的不足,完善了交通流跟驰理论。

| Abstract: | The car-following behavior was studied by molecular kinetics,the required safe distance was explored and an application model was built.By giving the reaction weights to various stimuli,a state equation for the isodirectionality of the responses of the driver to various stimuli was derived using the mathematical deduction.Based on this equation,a molecular car-following model was built to describe the car-following behavior.The results of analyses from the data validation and the experimental comparison showed that the proposed molecular car-following model describes the car-following behavior more completely and appropriately,makes up the deficiency of the speed-based car-following models,and improves the car-following theory. |
