摘要
根据中国西南山区低等级公路(二级以下)的路况条件,通过不同条件下的车速调查,建立了一种运行车速的估计模型,给出了一种用于西南山区公路的基于运行车速的线形安全性评价标准。开发的评价软件实现设计和使用阶段的可视化实时评价,并将该方法用于实际设计项目中。
Creating an estimation for operating speed and the Evaluation Criterion based on operating speed for road in the southwest mountain area by way of speed investigations under different conditions and the condition of the low class highway in the southwest mountain area. The visualization Real-Time evaluation for application and Design Stages of the software for Evaluation was realized. The method is applied in the several highway design.
