摘要： 交通流中车辆跟驰建模的研究在交通工程和智能交通系统领域内显得十分重要，其核心就是对驾驶员认知问题的测度.本文在总结以往跟驰模型的基础上具体讨论了AP (action point)模型，并对其不足之处做了改进，重点研究了后车跟随加速度的算法.此外，本文提出了驾驶员多信息处理机制和多通道判断决策概念，企图从控制论角度来对驾驶行为进行客观地定性分析和定量描述，以期正确地揭示交通流的本质特征.

Abstract: Car-following modeling in traffic flow theory has been becoming of increasing importance in traffic engineering and intelligent transportation system, the point of concentration in research is about measurement of driver cognitive. After reviewing historical models on car一following, this paper has analyzed in more detail the AP (action point)model，and ameliorated AP model by eliminating its deficiency, the emphasis of which is the deduction of the acceleration equations by which the following car is subjected. Furthermore，from the cybernetics perspective，this paper make an effort to accomplish qualitative analysis and quantitative description of driving behavior with driver’s multi-typed information system and multi-ruled decision-making mechanism so as to correctly reveal the essence of traffic flow characteristics.
