摘　　要：为探索急弯处不同警告标志位置对驾驶行为的影响机理,利用驾驶模拟试验,在急弯前设置5种不同位置的警告标志,观察车辆在弯前直线路段、弯道路段中的运行状态。结果表明,标志位置对直线路段的平均速度,直线、弯道路段的平均加速度、速度标准差均存在显著性影响;标志位置与急弯半径的交互效应对直线路段的平均速度、弯道路段的平均加速度有显著性影响。警告标志位置能够影响车辆在弯前直线路段的行驶速度、驾驶员在弯道路段对速度的纵向控制以及过弯前后速度的波动性;同时,对速度控制的影响还受到急弯半径的干扰。In order to explore the influence mechanism of positions of warning sign in sharp curve on driving behavior,a driving simulation experiment in carried out to observe the vehicle driving states in straight sections prior to curves and curve sections under the influence of 5 kinds of warning sign position prior to sharp curve. The result shows that（ 1） the positions of curve warning sign has a statistically significant effect on average speed on straight section,average acceleration and standard deviation of speed on straight and curve sections;（ 2） the interaction of sign positions and curve radii has a statistically significant effect on average speed on straight section and average acceleration of curve section;（ 3） warning sign position has an influence on the vehicle speed on straight section prior to curve entry point,driver＇s speed longitudinal control in the curve section and speed variation before and after curve entry point;（ 4） at the same time,the influence on speed control is interfered by the radius of sharp curve.
