This study deals with the weather elements which cause to traffic accident. The objective is to develop the accident models by season using the weather element data. In pursuing the above, this study gives particular attention to collecting such the data as the traffic accident by link and analyzing the differences in season using the various weather elements. The main results are the followings. First, Friday was analyzed to have the most accident rate, that was 16.3% of the total accidents. Second, Spring season was evaluated to have relatively more accident rate, which was 26.9%. Finally, one accident model by season which was statistically significant was developed. The most important variable in the model was evaluated to be average temperature. The R2 of the model was analyzed to be 0.819
