| Abstract |
This study examined the accident-related factors which affect the severity of pedestrian traffic accident by driver’s age. We used an ordered logit model that examined the determinant factors of pedestrian traffic accident’s severity using the 2014 TAAS data. The results of this study are as follows. First, traffic congestion and average speed of cars were statistically significant factors for the pedestrian accident severity for the model of 40~50 age or 60+ age drivers. Second, as physical environment factors, crosswalk or intersection variable was the most influential factor for the severity of pedestrian accident. In addition, areas near bus stations were strong factors for the severity of pedestrian accident in all models except for the model of 40~50 age drivers. Third, land use variables such as commercial and industrial floor area ratio were also critical factors. We conclude that the traffic accident factors affecting the severity of pedestrian traffic accident were different from each age group of drivers. The results of this study will be helpful to develop transportation policies for pedestrian safety by considering the characteristics of drivers. |
