Study on evaluation method for earthquake damage of road sections;

This model provides a basis for the evaluation and optimization of the different road section of a pavement.

One main reason for which accidents taking place frequently at plane curve road section with relaxed curve is that there lacks linear inducing sign or the linear inducing sign does not meet the requirements.

However, there are link travel times that are related to the queue length between those two extreme cases, so under such inflow rates dynamic link travel times should include free flow travel time as well as delayed time at the exit of the link.

Network representation models with node,link segment,lane as fundamental elements are put forward,which give a more accurate and detailed description of the road network topology and geometry,and lay a good foundation for the traffic simulation models to describe the network traffic state more realistically.

According to the present situations that accident occurrence rate is so high in Lanxiao section of National Highway 312, through the investigation and statical analysis of the accident data in history, the distinguishing method,the corresponding accident accumulation frequency curve has been put forward in the paper.

of slurry seal section,the paper introduced the application of slurry seal technology.

In order to improve the service of the road facilities of Tian-Xin road comprehensively and to assure the vehicle safety,the paper,according to the situation of the section,analyzes some unsafe factors of the section and points out some respective measures and strategies based on its features and its effects are better.

This paper introduces the basic conditions of bus lane, mainly analyzes the benefit emerged in the traffic operation improvement of street and intersection after bus lane used, and puts forward the method of benefit calculation.
