Incheon Metropolitan City has undertaken several initiatives to manage and improve its urban transportation infrastructure.

In late 2026, the city announced a 45-day emergency response system to address potential liquid hydrogen supply disruptions caused by scheduled maintenance at the SK Incheon Petrochemical plant. To mitigate impacts on the city’s hydrogen bus fleet, which comprises approximately 24% of its buses, officials planned to utilize both liquid and gaseous hydrogen stations to maintain service intervals.

Concurrently, the city is implementing technological upgrades to enhance transit efficiency and safety. These include expanding real-time traffic signal information to over 40% of regional intersections and significantly increasing the frequency of bus location data collection from 60-second to 3-second intervals. Further improvements involve installing new bus information displays and integrating public and private parking data into a unified system.

In October 2026, the city expanded its transportation scope through a successful Urban Air Mobility (UAM) flight demonstration between Yeongjongdo and Deokjeokdo islands. Conducted in collaboration with Incheon International Airport Corporation and the ‘K-UAM One Team’—including KT, Korean Air, Hyundai Motor, and Hyundai Engineering & Construction—the project aimed to verify UAM feasibility for improving medical and emergency access for island residents. 

The demonstration utilized helicopters to test flight routes, vertiport operations, and traffic management. Key technical achievements included KT’s verification of an AI-based traffic management platform and a hybrid 5G/satellite communication network, which reached a “100% communication success rate,” alongside the use of Korean Air’s ‘Across’ integrated control system.

## Claims

- Incheon will expand real-time traffic signal information to 1,635 intersections starting in November. (corroborated by 4 sources)
- The expansion will increase the proportion of signalized intersections providing real-time information from 20.5% to 40.2%. (corroborated by 4 sources)
- The bus location information collection cycle has been shortened from 60 seconds to 3 seconds. (corroborated by 4 sources)
- The city plans to install 209 new bus information displays by the end of the year. (corroborated by 4 sources)
- Data from Gangneung showed real-time signal information reduced speeding rates by 9.45 percentage points. (corroborated by 3 sources)
- The city aims to link with the national parking information system by December 2027. (corroborated by 2 sources)
