The Korea Expressway Traffic Authority said the number of accidents and deaths decreased by 33.2% and 75.6% from the 2016-2018 annual average as a result of analyzing 227 traffic accidents that carried out the “traffic accident-prone improvement project” in 2019.
The project is to analyze accident factors and improve the road environment by selecting points where more than three to five traffic accidents occurred a year. Using accident statistics and big data from the traffic accident analysis system, priority is determined among 400 branches and 16 sections nationwide every year and customized improvement measures are established.
The corporation cited Galmanaegeori Intersection in Seo-gu, Daejeon as a major improvement example. An average of 28.7 accidents occurred annually in Galmane Street over the past three years before the project was implemented, but the number of accidents decreased 54.7% to 13 per year as a result of pushing ahead with the project, such as installing traffic lights and speeding cameras and improving visibility.
Sinchon Intersection in Heungdeok-gu, Cheongju, Chungcheongbuk-do, was also a place where 6.3 traffic violations occurred annually due to rapid curves and quiet traffic, but the number of accidents decreased to one a year by installing traffic islands and pushing for anti-slip pavement.
