摘要
根据限速标志、振动减速标线、减速丘等3种典型车速控制措施的减速机理,从有效性和适应性2个方面建立了评价指标集,其中有效性指标包括驶入速度与通过速度差、驶入速度与驶出速度差;适应性指标包括心率增长量和加速度干扰,根据实际道路上的车载实验数据,采用模糊综合评价方法对不同地点车速控制措施的使用效果进行了综合评价,并探讨了基于行驶速度的车速控制措施选择方法.
According to the deceleration mechanism of three speed control measures, such as speed limit signs, rumble strips and speed hump, a evaluation set is established from two aspects： validity and adaptability. The validity indicator includes the difference between the entrance speed and the passing speed, and the difference between the entrance speed and the exit speed. The adaptability indicator includes heart rate increase and acceleration disturbance. The fuzzy comprehensive evaluation method is used to conduct a comprehensive evaluation of the speed control measures according to the experimental data that was collected on actual road. Finally, the choice method of the speed control measures based on travel speed is discussed.
