ABSTRACT
We developed two systems which manage the data related totraffic accident. One system conducts analyses using the information on accident,road, and weather, for example, calculation of the rate of theaccident depending on road condition or weather condition.Another analyzes using the information on safe facilities.For example, extraction of the sites which have accidentsrepeatedly.Using these functions, accident information is easily collectabledand road administrator's task to create document's on safetymeasures is supported.

EffectivenessEffectivenessThe system is useful for establishing
traffic safety measures, as the trend of accidents is detected.Awareness of traffic safety is increased
by using GIS.The result of questionnaire
70% of schools use the data for revising school route.More than 90% of schools request data (in digital format)
