| 摘 要： | 人类对于事件的反应机制决定了道路行驶车辆在跟驰过程中存在反应延迟现象。对几类常见跟驰模型中所反映出的延迟时间的含义进行了定义与区分。利用Matlab软件对GHR模型、OV模型以及FVD模型进行了2车跟驰状态和车队信号灯放行阶段的模拟,分析了这3类模型中反应延迟时间设置的必要性。结果显示GHR模型中反应延迟时间不可忽视,而OV模型以及FVD模型中反应延迟时间可以省略,同时也证明了各跟驰模型建模思路的合理性。

| Abstract: | Driver＇s response mechanisms determine the response delays in the vehicle-following process.This paper examines several common car-following models in which perception/reaction delay time is defined and differentiated.In this paper,Matlab is used to simulate several two car-following processes based on GHR model,OV model and FVD model to study whether it is necessary for the above models to include perception/reaction delay time.Study results indicate that response delay time within GHR model cannot be ignored,while that within the OV model and the FVD model can be omitted.This paper also shows the rationales of the above car-following models. |
