| 摘 要： | 为了研究环形交叉口入口道车辆跟驰行为，依据实地交通调查的数据，利用线性跟驰模型和回归分析方法对环形交叉口入口道跟驰车辆进行分析，分析结果表明：环形交叉口入口道的车辆跟驰行为是符合线性跟驰模型的，但是有别于普通道路上的车辆跟驰行为，其反应强度系数A的值在0．2—1．0之间，A值为0．38出现的概率比较大，占40％，进行稳定性分析可知车间距的摆动处于基本稳定和衰减摆动两种状态，是符合局部稳定性的．

| Abstract: | The car-following behavior of roundabout entrance lane is studied by using liner car-following and regression models for obtaining the car-following behavior to match the liner car-following behavior. However, it is different from the behavior on the road. The value of reaction intensity factor is between 0.2 to 1.0, and the value 0.38 appears relatively more often and accounting for 40%. The swing of car space headway is between stable status and decay swing with the stability analysis, and it is consistent with local stability. |
