Application of Spatial Data Mining in Accident Analysis System

Traffic accidents cause enormous losses for our country and plenty of national assets drain away every year, and therefore the task of traffic management is weightier than Mount Tai, but the complexity of traffic accident analysis has brought many difficulties to traffic management and decision-making. A three-layer analysis system based on spatial data mining of GIS is proposed in this paper, this three-layer architecture displays the whole process of accident data extracting, preprocessing and mining and it applies spatial data mining to GIS, which will certainly further expand the width and depth of GIS application field. Finally, this paper introduces the method of developing traffic accident analysis system by using ArcGIS Engine and C#.NET and gives the class realization of system main functions.
