SEOUL -- South Korea's top telecom service operator KT has started providing real-time information on some 910 traffic lights on the southern resort island of Jeju through its smartphone navigation app. The new service will help drivers pick a safe and ideal route to their destinations.

Jeju with a population of about 700,000 is a popular tourist spot. Ironically the island has the highest rate of motor accidents caused by tourists. According to government data, tourists were responsible for 49.9 percent of 4,239 car accidents in Jeju in 2018. About 70 percent of tourists use rental cars to move around the island.

KT said in a statement on June 25 that One Navi, the company's smartphone navigation app, shows real-time information about 909 traffic lights. The app's route-selecting algorithm finds the most ideal route to destinations.

"We hope One Navi's new service contributes to the establishment of a safe driving environment for Jeju residents and tourists," said Choi Kang-rim who heads KT's AI mobility business division. The service's application programming interface is open so that other service operators can use related information to help old and handicapped people safely use road infrastructure.

The service is based on Jeju's cooperative-intelligent transport system (C-ITS) infrastructure that digitally connects main roads. The system links cars and on-road structures such as traffic lights, road signs and buildings to monitor traffic. Drivers are notified when there's an accident nearby.
