本论文以渝黔高速公路扩能项目设计资料为依据,利用计算机软件的二次开发实现了高速公路全程运行速度预测;基于运行速度对渝黔高速扩能全程行车视距进行检查,发现了可能存在的视距隐患路段;利用计算机仿真技术,实现了运行速度下典型视距不良路段的三维视距检查及驾驶员空间视野渲染;从而为施工图设计提供可靠的依据,对视距不良路段进行分类,提出了切实可行的视距保障措施。归纳并形成了在设计阶段考虑视距要求的检算方法和处理措施,可为其他公路项目线路设计提供参考。
Based on the design data of Chongqing-Guizhou Expressway expansion project, this paper realizes the prediction of the entire expressway’s running speed by the secondary development of computer software. Based on the running speed, it examines the line-of- The existence of the line of sight of potential risks; the use of computer simulation technology to achieve a typical line of sight of the poor visibility of the typical three-dimensional line of sight and driver’s view of space rendering; thus providing a reliable basis for the construction drawings design, Classification, put forward a feasible line of sight protection measures. Summarized and formed in the design stage to consider the line of sight requirements of the accounting methods and treatment measures for other road projects line design reference.
