缓和曲线是构成公路平面线性的基本元素之一,而缓和曲线的长度取决于道路线性,运营能力等,通过综合对比国内外的相关资料,分析表明合适的缓和曲线长度对行车,交通安全有很大的好处,而不合理的缓和曲线长度影响驾驶行为和形势安全,并很有可能导致交通事故的发生,因此缓和曲线在直线和圆曲线间起到一个承上启下的连接作用,对保持列车曲线运行时的平稳性起到关键作用。
緩和麯線是構成公路平麵線性的基本元素之一,而緩和麯線的長度取決于道路線性,運營能力等,通過綜閤對比國內外的相關資料,分析錶明閤適的緩和麯線長度對行車,交通安全有很大的好處,而不閤理的緩和麯線長度影響駕駛行為和形勢安全,併很有可能導緻交通事故的髮生,因此緩和麯線在直線和圓麯線間起到一箇承上啟下的連接作用,對保持列車麯線運行時的平穩性起到關鍵作用。

the transition curve is one of the basic elements of highway plane linear, and the transition curve length depends on the road linear, operation ability and so on, through comprehensive comparison of related data in domestic and at abroad, analysis showed that the suitable length of transition curve on traffic, is of great benefit to traffic safety, and length of transition curve of unreasonable driving behavior and situation security, and is likely to lead to the occurrence of traffic accidents, so the transition curve plays a connecting role forming a connecting link between the straight line and circular curve, a key role on the stability to keep the train running on curve.
