平面交叉口智能化竖向设计

Intelligentized Vertical Design of Road Intersection

在比较国内外已有的平面交叉口竖向设计软件基础上,提出一种全新的交叉口数学模型——M ESH-GR ID模型。基于该模型的交叉口设计方法简捷、精确,适用于所有交叉口样式,能快速绘制等高线、标注板块高程,更能实时直观的查看、调整交叉口设计面三维模型。

This paper analyzes the existing softwares of vertical design in road intersection in the world, advances a new mathematic model MESH-GRID model for road intersection. The method based on this model is very succinct and accurate. It can be used in all intersection styles. This method can draw contour line and label the designed elevation of road plate fleetly. Moreover, it can observe and modify the three-dimensional model of the designed surface of intersection momentarily and visually.
