Abstract: Collecting the traffic accidents data of Han Ning highway in 2008, 2009 and 2010 three years, through two aspects of time and space to do statistical analysis and data mining of the traffic accidents of this highway. The result of the analysis is that accident rates have a certain relevance to time and space. From the time perspective, holidays and vacation days are accident high-risk days. From the space perspective, accident rate in the ascent and in the downhill are higher than on the straight road, cars go straight have a higher accident rate than in the corners, traffic accident rate in single-km single-lane tunnel is higher than outside the tunnel. Through the time and space distribution rule of the traffic accident, educating traffic participants follow the time and space distribution rule to restrict their behavior. Educating traffic managers obey the time and space distribution rule of traffic accident to adopt targeted management measures and engineering measures. Both of these two aspects have very important significance in reducing traffic accidents.

This made traffic guide information can’t be published regularly and in time. It also reduced down expressway net’s ability of providing traffic guide information for society. Regard CMS on expressway net as objective, after sorting and concluding guide information by scene analysis, the paper suggests a systematic method of processing traffic guide information based on dynamic traffic information automatic and prove it by an application. It can send detour information to each piece of CMS on expressway net quickly without redundant information. Traffic guide level on province expressway net would be improved extremely.
