Research And Development Of Road Transport Vehicle Accident Reduction Analysis System Based On Visualization Technology

Road transport based support playing an important role in national economy,in the social and economic development,many need to rely on the stability of road transport industry to promote the development of its own,but with the rapid development of industry,road transport traffic accidents often happen in our country,for the country and the people’s cause huge personal and property loss,the security situation is not optimistic.Therefore,it is very important to analyze the causes of accidents effectively.Highway scientific research project by the ministry of transport the freight logistics organization mode based on Internet,industry regulation and policy research as the foundation,using visualization technology reducing traffic accident scene,and on the basis of the analysis of accident information,the auxiliary user observation and research on the traffic accident,this paper analyzes the reasons of the accident.This paper mainly studies the related technologies and algorithms of road transport vehicle accident reduction analysis,and develops the system.In this paper,combining with the characteristics of road transport traffic accidents,based on the theory of visualization technology and interactive design of traffic accident scene reduction(computer simulation)and based on "time circle diagram"traffic accident information analysis algorithm;Designed by the method of using Cesium map engine and Fisheye view reduction and information analysis system for traffic accident scene,the accident scene simulation,and by the method of "focus and context" to provide users with the information of the accident analysis of interaction,the accident information through the change of time series,mining the periodic typicality and accidents in road transportation traffic accidents.At the same time through the LOD level model algorithm optimize the scene rendering of WebGL,and design the LOD error calculation method,according to different level resolution raster data,namely the level of adjacent tiles can be smoothly transition when switching.This paper made a system the information visualization and interaction design theory overview,analysis of visualization technology home and abroad and the research status of road transport traffic accident,introduced a variety of visualization technology and principle,and analyses the applicable scenario.On the basis of the traffic accident of the road transport information,traffic accident scene in the visualization module and traffic accident information analysis visualization module information comprehensive analysis about the accident,the auxiliary user observation and research on traffic accident,and determine the accident reason.
