高速公路互通立交区综合调查

Comprehensive Investigation of Expressway Interchange Section

高速公路互通立交是公路交通网络中的重要节点,也是公路沿线城镇的主要进出口门户。因此互通立交的设计应体现"以人为本"设计理念,不但要满足交通需求,还要提供安全与舒适的运行条件,追求与自然环境和社会环境的和谐一致,体现在设计中则是对包括安全、环境、功能、用地和成本等多因素的综合考虑和更为灵活的设计手法。要达到这一目标,就要求设计人员在测设阶段细化互通立交区的综合调查研究。

Expressway interchanges are important nodes of highway traffic network, are also the main entrances and exits of the towns along highways. Therfore, interchange design should incarnate the idea that ＂people oriented＂. The design should not only meet the traffic demand, but also provide safe and comfortable driving condition, as well as pursue the harmoniousness with natural environment and social environment, which means the comprehensive consideration to safety, environment, function, land, cost and other factors and more flexible design techniques. To achieve the goal, designers should conduct comprehensive investigation study in survey and design stages in details.
