| Abstract |
This study aimed to identify the changes in driver behavior and the impact of reducing accidents due to the operation of ADAS vehicles following the popularization of advanced driver assistance systems (ADAS). Existing studies have focused only on changes in driving behavior after installing ADAS, and the reliability of the accident reduction effect was low due to the small number of experimental vehicles. The data used in this study were the results of the Seoul City corporate taxi pilot test and insurance company accident statistics, which were used to increase the reliability of changes in driving behavior and accident reduction effects.The research results can be summarized in three points as follows. First, taxi drivers' dangerous driving behaviors were high in the following order: right lane departure (28 %), failure to maintain distance between cars (27.4 %), and left lane departure (22.9 %). In driving tests with general drivers, failure to maintain
distance between cars was also the most common. Second, after installing ADAS, about 20 % of drivers' risky driving behaviors decreased, and among them, maintaining a safe distance from the car in front improved the most. Third, after installing ADAS, the effect of reducing accidents was minimal in terms of the number of accidents, and the severity of accidents, as analyzed by insurance payments per case, decreased by 42.6 %. Analysis of insurance statistics showed a significant decrease in insurance payments per case for rear-end collisions and side collisions. As autonomous vehicles evolve based on ADAS technology in the future, changes in driver behavior and accidents should be continuously analyzed and utilized in policy making. |
