AI road-pavement damage detection
Korea Expressway reported road-damage compensation falling from KRW4.1 billion to KRW3.5 billion while using AI inspections
Problem
Manual inspections struggled to cover aging highways and identify pavement damage quickly enough for repairs.
Approach
Korea Expressway began operating AI pavement-damage detection in 2018. Inspection vehicles combined high-resolution cameras with precision GPS. AI analyzed damage in real time, assigned urgency levels and passed urgent findings to staff for repairs.
Results
Takeaway
Detection was connected to repair escalation. The compensation decline was an operating-period comparison, without a controlled estimate of AI's contribution.
