Abstract
It is in urgent need to build a traffic accident information spatial-database based on GIS. The contents of a perfect traffic accident information spatial-database should include three parts, i.e. spatial-database, influential factors database and database of metadata and data dictionary. Its important application value is described. The data in the database are organized with the idea of layer-organization in GIS. The structure of each table and correlation in-between these tables are designed in detail. The established traffic accident information spatial-database covers the object of traffic accident, persons, vehicles, roads and their surrounding, which could provide perfect data support for the study of traffic accidents.
