摘要
为了研究边缘率标线的时间频率及角度对行车减速的影响,选择30°,45°,135°和150°开展路上试验实证研究,对试验数据进行有无对比分析和有重复双因素方差分析。结果表明:4组试验中,角度布置值为150°时,驾驶人减速效果最明显,使得平均车速、85%位车速、车速标准差分别降低7.68,10.14,1.58km·h-1,驾驶人采取减速行为强度最大,减速度区间为[-0.25,-0.49]m·s-2;角度值越大减速效果越明显,时间频率越大减速效果越明显;时间频率与边缘率标线角度对减速效果的影响存在协同交互作用。
For the purpose of research on the effects of edge rate bars＇ temporal frequency and angle on deceleration, road experiments were carried out with four angles （30, 45, 135 and 150 degrees）. Data were analyzed by the with and without comparison method and the reusable two- factor analysis of variance. The results show that the average speed, 85% speed and standard deviation of speed respectively decrease by 7.68, 10.14 and 1.58 km · h^- 1 , and the decreases are greatest when the angle is 150 degrees in the four experiments. The distribution range of deceleration is within [-0.25,-0. 491 m · s^-2 when the driver takes the greatest deceleration. The greater the angle and the temporal frequency are, the more significant the deceleration is. The temporal frequency and angle have synergetic mutual function in the impact on the decelera- tion.
