北京机场南线(京承高速公路—东六环路)公路工程位于北京市东北部,是首都机场扩建工程配套建设的三条高速公路之一。随着我国高速公路建设的迅速发展和机动车保有量的急剧增加,我国高速公路交通事故率呈上升趋势。道路交通安全问题已成为摆在我们面前的首要问题,而高速公路交通安全设施是有效减少交通事故的具体措施之一。高速公路交通安全设施的设计要充分体现"以人为本"的设计理念,将安全放在首位,体现对人的关注,体现人性化的要求,注重公路安全性、方便性、舒适性、愉悦性的和谐统一,为道路使用者提供安全保障和人性化的服务,切实提高公路交通的安全水平和服务水平。高速公路交通安全设施是高速公路的重要组成部分,是发挥公路经济效益、保障行驶安全必不可少的配套设施。该文通过机场南线交通设施设计的理念和设计原则,并以设计实例论证了交通安全以人为本的安全设施设计理念。

Design Idea and Think of Traffic Facilities for South Line of Beijing Airport

Beijing Airport South Line (Jingcheng Expressway–East No.6 Ring Road) Highway Project is located at the northeast of Beijing and is one of three expressways supported for the construction of the extension project for the Capital Airport. With the high-speed development of the expressway construction and the sharp increment of vehicle inventory in China, the expressway traffic accident rate presents the rising trend. The traffic security of road has become the first problem. The security facilities of expressway traffic are one of the detail measures to efficiently decrease the traffic accidents. The design of expressway traffic security facilities will fully embody the design idea of "taking people as the foremost", put the security at the first, embody the attention to the people, present the humane requirements, emphasize the highway security, convenience, comfort, joviality and harmony, provide the service of security assurance and humanisity for the road users, and really enhance the security level and service level of highway traffic. The traffic security facilities of expressway are the important component of expressway, and are the necessary supported facilities to play the economical benefit of highway and to ensure the driving security. The article demonstrates the design idea of security facilities by taking people as the foremost of traffic security according to the design idea and design principle of the traffic facilities for the airport south line and based on the design cases.
