机载LIDAR技术在现有高速公路路线指标评价中的应用

Application of Airborne LIDAR Technology in Existing Expressway Route Indicator Evaluation

文章针对因施工误差、运营中的不均匀沉降而导致的现有高速公路部分路段路线不合规范要求的情况,提出了利用机载LIDAR技术,在不干扰交通的情况下获取现有高速公路的三维数据,并通过平纵拟合设计实现对现有高速公路的路线指标评价,以发现高速公路运营过程中的安全隐患,预防交通事故的发生。

For the situation that the route of some existing expressway sections did not com- ply with the standard requirements caused by the construotion error and uneven subsidence during the operation, the article proposed to use the airborne LIDAR technology, to obtain the three-dimensional data of existing expressway without disturbing the traffic, and to real- ize the indicator evaluation of existing expressway routes through horizontal and vertical fit- ting design,so as to find the safety hazards during the operation of expressway and to pre- vent traffic accidents.
