基于Origin的隧道入口运行车速计算模型的探讨

运行车速被广泛的应用于检验公路线形。该文对运行车速计算模型采用了一个新的思路:考虑了隧道对运行车速的影响。该研究以人为本,分析了影响隧道入口驾驶员行车速度的三个主要因素:隧道洞内外光线差值、路基宽度差值以及洞口位置,运用Origin软件统计得出高速公路隧道入口运行车速计算模型。该研究完善了运行车速模型,为高速公路交通安全的评价提供了很好的前提条件。

Discussion of Tunnel Entrance Driving Vehicle Speed Calculation Model Based on Origin

The driving vehicle speed is widely applied to check up the highway alignment.A new thought is used for the driving vehicle speed calculation model in the article to consider the tunnel influence on the driving vehicle speed.Taking people as the foremost,the article analyzes three main factors influencing the drivers’driving speed at the tunnel entrance:the light difference values inside and outside of tunnel,the roadbed width difference value and the tunnel entrance position,and applies Origin software to get the expressway tunnel opening driving vehicle speed calculation model. The article perfects the driving vehicle speed model and provides the better premise condition for evaluating the expressway traffic safety.
