                          道路减速带存在的问题与优化设计

                          时间:2018-12-20 10:43作者:张圆 程苗
                          本文导读:这是一篇关于道路减速带存在的问题与优化设计的文章,随着中国社会经济的发展和道路建设的不断完善,越来越多的人购买汽车,但城市道路交通事故日益突出。其中,车辆超速和违规是中国城市道路交通事故发生率高的最主要的原因。

                            摘    要: 通过分析现有减速器存在的缺陷问题,然后根据减速器自身的设计特点和用途,从设计方面提出了一些新的优化方法。随着社会的快速发展和人民素质的逐步提高,传统减速带对城市道路过往车辆的不利影响减小了。特别是有意识地减速车辆,能有效促进社会和谐发展。它具有一定的理论支持以及技术的可操作性等,发展前景十分广阔,对维护公共交通秩序,减少交通事故的发生,具有十分重要的意义。

                            减速带的设置必须遵循近年来使用减速带的原则追求速区的科学设置可以有效改善道路交通安全状况。为了有效,在制定具体的实施计划时,有必要注意特殊性,系统性和配套性的原则。特殊性原则:必须根据道路等级,交通流量结构,实际平均速度,道路,路面材料等实际情况。具体情况具体分析从而来确定减速带的类型,使用材料,减速带的尺寸和形状,以及连接和安装方式。系统性原则:减速带设置的具体位置和相应数量必须基于研究或实际道路测试。为了确保减速带使用的安全性和效率,在设置减速带过程中必须要与其他交通安全装置(各种标记)一起使用,从而减少交通事故的发生。道路减速带存在的问题:缺乏“人性化”设置。在路上可以看到多种减速方式。这些减速带的宽度约为35厘米,高度为30至100毫米。以这种方式设计的齿轮单元通常具有太长,太宽,太高,从而引起车辆受损,以及造成车辆悬架系统的轻微损坏和发动机油底壳严重破损的问题。另外,每次当人们开车和骑车时,他们都会遇到严重撞击,从而严重影响开车舒适度。同时,为了避免减速带在开车过程中产生的颠簸,骑车者经常选择减速带和肩部之间的间隙来通过。在高峰时段(例如通勤),它经常拥堵,自行车造成碰撞从而给人们带来一定的危险。另外,还存在设置不科学等问题。减速带的运输设施和交通标志的国家标准尚未标准化。特别是在城市道路上,速度颠簸过于随意,过于随意设置,不会对城市交通的安全性,舒适性和速度产生不利影响。减速带设置缺乏专业性,系统性和兼容性原则,不仅打乱了交通流量的顺序,还进一步降低了道路交通的安全性。噪声污染也比较严重。当车辆通过减速斜坡和减速带时的速度如果太迟,这时轮胎将通过减速斜坡和减速带摩擦发出“嘟嘟”声,并且这个声音会随着车速的增加而增加。特别是当大型卡车通过时,声音更加明显,并形成噪音污染。在城市道路上,缓慢的山脉和减速带已成为“令人不安的存在”。
