运行速度作为线形设计效果最直接的反映,与公路交通安全密切相关,运行速度概念和设计方法在公路设计安全方面的应用,已经得到了广泛的认可。因此,其预测模型也成为大家关注的焦点。文章首先探讨了影响运行速度的因素,然后研究了运行速度的两种预测模型,并针对其中较为成熟的预测模型,编制相应的程序,使运行速度的应用更为方便和快捷。 As the most direct reflection of the linear design effect, the running speed is closely related to the highway traffic safety. The application of the concept of running speed and the design method in highway design safety has been widely recognized. Therefore, its prediction model has become the focus of everyone’s attention. The article first explores the factors which affect the running speed, then studies two prediction models of running speed, and according to the more mature prediction model, compiles the corresponding program to make the running speed more convenient and faster.
