Research On Road Traffic Accident Prediction System Based On GM-BP Combined Model

With the rapid development of China’s economy since the reform and opening up,the quality of life of the people is getting better and better.At the same time,the scale of urban transportation and the number of private cars have also increased.The traditional road traffic management model has been unable to meet the normal operation of contemporary traffic flow.Traffic jams have caused serious travel difficulties.Traffic jams have seriously affected the development and progress of cities.Many core road sections still use dozens of transportation systems.The scale and standards of design years ago,most cities in China at this stage are affected by traffic conditions.Therefore,for the prediction of road traffic accidents and the scientific and effective management and regulation of traffic conditions,it is of great practical significance to design an efficient traffic prediction system.This paper takes the design and implementation of traffic accident prediction system as the goal,uses statistics,information and computing science and other disciplines to fuse,and estimates the general laws of traffic accidents.Design,the design of the system mainly includes four aspects: data collection,accident analysis,and data query and evaluation prediction.Data collection is mainly used to establish a database of traffic accident systems.Accident analysis mainly studies the time and shape of traffic accidents and analyzes the characteristics of traffic accidents.Data query is mainly set by query conditions and search conditions to view Based on the statistical results,the final evaluation and prediction are mainly to evaluate the road safety level.At the same time,different prediction methods are compared to select the optimal prediction scheme.At the same time,this article also tests different functions of the system to ensure the efficiency and quality of the system operation.The author hopes that through the research in this article,a traffic safety accident prediction system will be realized,which will provide valuable reference opinions for better management of road traffic in China and timely and correct and efficient accident response measures.
