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。
In order to study the impact of the time frequency and the angle of the edge rate marking on the driving deceleration, we choose 30 °, 45 °, 135 ° and 150 ° to carry out the road test empirical study, whether there is comparative analysis of the test data and repeated two-way ANOVA . The results show that when the angular arrangement value is 150 °, the deceleration effect of the driver is the most obvious in the four groups of experiments, so that the average speed, the standard deviation of the speed of 85% and the standard deviation of the speed of vehicle decrease by 7.68, 10.14 and 1.58km · h-1 respectively. The decelerating range is [-0.25, -0.49] m · s-2. The larger the angle value is, the more obvious the decelerating effect is. The greater the time frequency is, the more obvious the decelerating effect is. The time frequency and edge rate marking angle There is synergistic interaction between the effects of deceleration effects.
