公路平面线形设计的五单元导线法丁建明李方（东南大学交通学院，南京２１００９６）随着我国高等级公路的不断修建，对公路平面线形的要求越来越高，传统的直线为主的导线设计方法很难满足线形随地形、地物改变而变化的情况，特别是在立体交叉线形设计中显示出明显的不...
Based on the traverse method and taken incomplete clothoid and arc as the foundation unit, a five element traverse method for highway horizontal alignment design is presented. The essence of the three element traverse method and the curve design method which is widely used abroad are adopted in this method. A computer program is developed. It can rapidly and accurately calculate the azimuth and the coordinates for both the characteristic points and any individual point on the horizontal alignment.
