Busan Metropolitan City has implemented an artificial intelligence (AI) traffic management system through a 2.9 billion won project. The initiative focuses on enhancing road safety and traffic flow by utilizing real-time data analysis.

Key components of the system include a real-time intersection information service and an intersection flood detection system deployed at 11 high-risk locations to provide detour information during heavy rainfall. The city has also expanded infrastructure to share real-time signal information with mobile navigation apps and connected vehicle services to mitigate speeding and intersection blocking.

Pilot operations of these smart intersection technologies, including real-time signal control and smart responsive signal systems, have reportedly reduced intersection delay times by over 10% and 36%, respectively.
