摘　　要：为明确城市信号交叉口的车辆跟驰行为特性,基于自然驾驶试验数据,对车辆在减速、加速跟驰状态的车头间距、车头时距和相对速度进行分布特征分析以及与跟驰速度的相关性分析。结果表明:减速跟驰状态的相对速度主要集中于[-3.4 m/s,0.6 m/s],加速跟驰状态主要集中于[-0.9 m/s,2.6 m/s];减速跟驰状态和加速跟驰状态的车头时距随后车跟驰速度变化趋势相同,确定了跟驰速度小于20 km/h的车头时距阈值;去掉跟驰速度小于6 km/h的数据后得到的减速跟驰、加速跟驰状态车头时距和车头间距均呈正偏态分布,车头间距集中于5~30 m,车头时距集中于1.5~3.5 s;两种跟驰状态车头间距、车头时距的5^(th)、50^(th)、95^(th)特征值与跟驰速度具有较强的相关性。In order to clarify the characteristics of car-following behavior at urban signalized intersections,based on the natural driving test data,the distribution characteristics of space headway,time headway and relative speed of vehicles in deceleration and acceleration car-following states were analyzed,and the correlation with car-following speed was analyzed.The results show that the relative speed of the deceleration car-following state is mainly concentrated in[-3.4 m/s,0.6 m/s],and the acceleration car-following state is mainly concentrated in[-0.9 m/s,2.6 m/s].The change trend of the time headway of the deceleration car-following state and the acceleration car-following state is the same,and the time headway threshold of the car-following speed less than 20 km/h is determined.After removing the data of car-following speed less than 6 km/h,the headway and headway of deceleration car-following and acceleration car-following are positively skewed.The space headway is concentrated in 5~30 m,and the time headway is concentrated in 1.5~3.5 s.The 5^(th),50^(th)and 95^(th)eigenvalues of the space headway and time headway of the two car-following states have a strong correlation with the car-following speed.
