The article introduces the performance and characteristic if this new material of the Glasal in the ornamental shield material for the underground traffic engineering in detail, discuss its application in the urban underground traffic engineering, and expects its spreading in the social benefit and the economical benefit.

The exploitation of underground space becomes the main trend in the future,in this paper the underground connecting engineering is scientifically defined,six constructing modes of underground connecting project are put forward,the construction benefits are analyzed and the main problems for its construction are pointed out.

In this article the changes of traffic forms due to the technology development, the direction of the city traffic development and the necessity of the exploitation of underground traffic are med.

In this paper, the combined development mode of underground traffic and urban green area is put forward by analyzing the urban green areas and urban traffic problems at present in China.

Key points for of traffic engineering construction and supervision;

Study and analysis on the teaching of combining the traffic engineering theory with practice;

Design and realizing method of traffic engineering CAE system;

The application of modern information management in the construction of traffic projects;

On how to do well consultative examination of traffic project design for highway

According to the volume of traffic flow and demands of economic development in specific area,we may design a traffic project with comprehensive plan but implemented by different stages.

In the paper, we study random serving scheme in communication engineering by queuing theory , gain the quantity standard which show the effect of the scheme, explain relationship between the standard and serving way.
