The purpose of this study is to investigate and verify the perception of traffic inspectors whether there is a realistic possibility of injuries to the driver and occupants of the vehicle in relation to the low-speed collision accident due to the change in speed in minor traffic accidents.
For verification, data was collected through a questionnaire for 252 traffic inspectors in Korea. Based on the collected data, it was hypothesized that minor traffic accidents will have a positive (+) effect on perception of minor injury. To verify the hypothesis, correlation analysis and multiple regression analysis were performed using IBM SPSS statistics (version 21). The results of analysis are as follows.
First, as a result of the correlation analysis among the variables of departure after stopping, driving attitude and habit, Madimo, and medical certificate, all the variables were found to be correlated with each other.
Second, as a result of multiple regression analysis, in a low-speed reverse collision accident, a rearview mirror contact accident, and a collision accident among departure accidents after stopping, when the vehicle's speed is 5km/h and less than 8km/h, the collision impact force is significant in the occurrence of injury to the driver and occupants of the vehicle. In the case of a speed of 10km/h, a low-speed reverse collision accident among the variables, a side contact accident in the case of a speed of 15km/h, a rearview mirror contact accident, and a collision accident in the case of a speed of 20 km/h were significantly correlated with the incidence of injury.
Third, among the driving attitude and habit variables, it was found that the impact of a collision accident caused by inadequate gaze to the left and right while driving at a vehicle speed of 5km/h or less had an effect on the injuries of the driver and occupant of the vehicle.
Fourth, among the variables related to Madimo, it was found that the application of Madimo at a vehicle speed of 10km/h had a significant effect on the traffic inspector's perception of minor injury.
Lastly, among the variables of the medical certificate, it was confirmed that the reliability of the injury certificate due to the collision of the vehicle in front during the vehicle speed of 5km/h and 8km/h had a statistically significant effect.
In summary, in this study, traffic investigators recognized that the collision impact force of departure accidents after stopping, the driver's driving attitude and Habit, Madimo, and reliability of medical certificate have a significant effect on minor injury. But, previous studies analyzed that a collision accident caused by a vehicle speed of 3-7km/h or 12km/h does not cause injury.
That is, in this study the investigator recognized that injury could occur in a vehicle speed of 5km/h, 8km/h, 10km/h, 15km/h, and 20km/h, because the degree to which the impact force is transmitted to the body depends on the attitude, behavior, and physical characteristics of the occupant.
Contrary to the results of previous studies, this study is of great significance in that it has confirmed that traffic investigators are aware of the factors that will affect the occurrence of injuries even in low-speed collision accidents.
