Effects of Weather Conditions on Road Surface Damage

This study analyzed the impact of weather conditions on road surface damage across five regions: the Seoul metropolitan area, Gangwon, Chungcheong, Jeolla, and Gyeongsang.Using data from the past three years, weather variables such as rainfall, temperature, and rainfall intensity were considered to identify the influencing factors in each region.The results showed that the effect of weather factors on road surface damage varied by region.In Chungcheong and Gyeongsang, rainfall was found to have a significant impact on road surface damage, whereas in the Seoul metropolitan area and Gangwon, weather factors had minimal influence, suggesting that other factors such as traffic volume and vehicle types may play a more significant role.Consequently, the study concludes that differentiated road maintenance policies are needed for each region.In particular, drainage management and measures to address heavy rainfall are essential in Chungcheong and Gyeongsang, while traffic and snow removal factors should be considered in road management for the Seoul metropolitan area and Gangwon.The results of this study are expected to serve as fundamental data for establishing region-specific road maintenance strategies in response to climate change.
