干线公路无控交叉口振动减速标线设计与舒适性评价

Transverse Rumble Strips Design And Comfort Evaluation at Arterial Highway Unsignalized Intersection

为了降低干线公路无控交叉口处驾驶员超速行驶产生的交通事故,在交叉口处进行振动减速标线设计,并探讨了振动减速标线的参数设计方法.采用改进加权加速度均方根与K值系数法相结合,建立振动频率、振动幅度和车速变化因子的综合舒适性评价模型.针对不同振动减速标线组数和车辆减速度,进行振动减速标线设计,分析不同减速效果下驾驶员的舒适性.

To reduce the traffic accidents caused by driver＇s speeding behavior,this paper sets transverse rumble strips at the functional area of intersection,and discuss its＇ parameters design method.After that,we use improved weighted acceleration RMS and K coefficient method to establish the drivers＇ comfort model by vibration frequency/amplitude/speed change.At last,we design some cases which are different from each other by deceleration and group,analyse drivers＇ comfort and use it to optimize the transverse rumble strips design
