''Sustainable development'' recently becomes an issue in all fields. Due to this global paradigm change, Korea government gives emphasis to ''Green Growth'' policy as a national development strategy. Thus, transportation has been affected by the change, and the researches associated with roundabout have been implemented.
This study deals with the traffic accident in circular intersection. The purpose of the study is to develop the accident models by collision type. In pursuing the above, this study gives particular attentions to developing the appropriate models using count data model, Tobit model, multiple linear and nonlinear model, and statistical analysis tools. The main result are as follows.
First, in the case of ''head-on collision'', multiple linear model which was statistically significant ( value was 0.391) was developed.
Second, in the case of ''side right-angle collision'', multiple nonlinear model was analyzed to be the best fit to the data. The multiple nonlinear model which was statistically significant( value was 0.592) was developed.
Third, in the case of ''rear-end collision'', multiple linear model was analyzed to be the best fit to the given data. The (0.753) was evaluated to be statistically significant.
Fourth, in the case of ''other type'' collision, multiple linear model which was statistically significant ( value was 0.368) was developed.
Finally, such the common variables as diameter of central island, stop line and yield line were adopted in this study.
