Development And Study On The System Of Data Collection And Diagram Drawing On The Road Traffic Accident Spot

At present the data collection, the spot diagram drawing, and the accident analysis at the spot of the road traffic accident in our country are mainly depended on the artificial method to carry on, thus they are hard to tackle, lack of accuracy and time-consuming.On the foundation of calculator technology, the article thoroughly researches and inquiries the fast collection of the spot data, the precision of the spot diagram drawing, and the data system in the accident analysis technology.This article firstly aims at the road traffic accident calculator analysis calculation and simulation reappearance technology, by researching the spot data collecting system thoroughly, and relying on the "Traffic accident analysis and reappearance system" independently developed by the Transportation safety topic set of Chang An University, determined the traffic accident analysis and reappearance database.Next, in this foundation, developed the road traffic accident spot diagram drawing system, determined the database of the traffic accident spot diagram drawing system. And the same time developed the construction of data frame for the road traffic accident spot diagram drawing technology and the integration accident reappearance technical.This system rests on GB11797-89, developed by the platform of Visual C++6.0,and has carried on the application in the actual traffic accident, proved to reduced the time of the traffic accident spot diagram drawing greatly, enhanced the criterion of spot diagram drawing, in the meantime provided comprehensive, accurate and reliable analysis data for the accident analysis and reappearance technology.
