客货分离式多车道高速公路货车车道设计速度选用研究

Research on the Design Speed Selection for Passenger and Freight Separation Highway

通过对京哈高速绥中至盘锦段现状货车运行速度的调查,结合公路功能定位、交通量条件、货车驾驶员的问卷调查,综合考虑项目地形条件、运营安全性及运营效率的情况下,确定了绥中至盘锦段货车专用道设计速度取100km/h为合理经济的设计速度。京哈高速绥中至盘锦段货车专用道设计速度选用的确定为专用道路线平面、纵面、横断面、超高、视距等设计指标的选取提供了依据。

Based on the survey of status trucks operating speed at section Suizhong-Panjin of Jingha Expressway, and combined with the road function, traffic conditions, truck driver＇s questionnaire survey, it synthesize considering project terrain conditions, operational safety and operational efficiency to determine the truck lanes design speed 100 km/h as a reasonable economic design speed for the section. The design speed of the truck lane provides the basis for the design indicators of the route plane, vertical, cross-sectional, super-elevation, sight distance, etc.
