Abstract
In this paper, the GIS for traffic accident analysis is made to provide several advantages, such as viewing the distribution of accidents at different situations effectively and considering in detail the accident locations through data segmentation. In the process of building the system, three databases (all roads, trunk roads and local roads) are created for the analysis, and using these, many factors causing accidents are found out effectively.
In making statistical traffic accident models, the use of the Poisson regression model that considers rare phenomena is the best method in evaluating the factors in traffic accident analysis.
