高速公路交通工程及沿线设施对道路主体工程设计的影响

Influence of Freeway Traffic Engineering and Road Facilities on Roadway Design

高速公路设计是由路桥主体工程设计和交通工程及沿线设施设计组成的复杂系统工程。本文在介绍交通工程及沿线设施设计内容的基础上，剖析其对路桥主体工程设计的影响。

Currently,freeway design is composed of two coordinating parts,namely roadway design as well as traffic engineering and road facilities design.The later part will usually impose impacts upon its former counterpart.What the impacts are and how they work are discussed in this paper.
