| 摘 要： | 使用视频采集技术对通过平乐园南路口减速丘的车辆运行速度数据进行调查。运用插值分析法,建立了车辆行驶速度和距交叉口距离的关系;利用单因素方差分析法,对距交叉口的距离与机动车行驶速度进行显著性分析,研究了城市道路交叉口设置减速丘后机动车的减速效果。结果表明,城市道路交叉口设置减速丘后机动车速度衰减了42.87%,且距交叉口的距离对于机动车行驶速度是有显著影响的。在交叉口进口道16 m范围内,机动车在行驶据交叉口3.5 m处时,其行驶速度会有显著变化,3.5 m处显著性水平为0.01<α=0.05。

| Abstract: | Video cameras technology is carried out at Pingleyuan south intersection with speed hump to collect the change of operating speed.The relationship between speed and intersection interval is established by Lagrange's interpolation method.The statistically significant result of vehicle operating speed and intersection interval is analysed by Analysis of Variance(ANOVA) method to discuss the speed reduction effect of intersection speed hump on urban road.The result shows that(1) on urban road with intersection... |
