摘要
振动减速带是公路上常用的一种强制减速设施,对控制车辆车速,提升行车安全有重要作用.为了合理设置振动减速带,文中根据车辆行驶速度,以车辆竖向振动加速度为评价指标,对减速带外形进行优选;并利用错视觉原理对减速带的尺寸和色彩进行了新的设计.后期利用3DStu-dio Max软件制作视频,引入SD法(semantic differential method)对方案进行评价,结果表明振动减速带采用抛物线圆弧相切形状比圆弧形的竖向振动更小,行车舒适性更高;同时采用错视觉安全色,具有色彩鲜明、立体感强等特点,视觉减速效果显著优于普通减速带.
Vibrating deceleration strip is a forced deceleration facility, and is the key factor to control vehicle speed and ensure driving safety. In order to strengthen the deceleration effect of the facility, according to the design velocity, the deceleration＇s figuration was preferred based on the index of vertical vibration acceleration. The size and color of the vibrating deceleration were designed based on the visual illusion principle. The mock video was made by the 3Dmax software, and the SD Method （Semantic Differential Method） that the deceleration strip＇s was used to evaluate the effect parabola-arc figuration has less of the design method. The vertical vibration, and mor than arc figuration. The deceleration strip＇s safety color is more effective to decelerate th common strip for its vivid color and strong 3-dimension effect. results：show e comfortable e vehicle than
