KT Builds Next-Generation Intelligent Transportation System on 18 Roads in Ulsan

Applied to a 142.6 km Section

[Asia Economy Reporter Cha Min-young] KT announced on the 20th that it has established a next-generation intelligent transportation system (C-ITS) to alleviate urban traffic congestion and prevent cargo truck accidents in Ulsan Metropolitan City.

Ulsan City was selected as a target for the "Next-Generation Intelligent Transportation System Demonstration Project" promoted by the Ministry of Land, Infrastructure and Transport in 2019, investing 28 billion KRW in project costs, including 15 billion KRW in national funds. KT was selected as the project operator in December 2019 and carried out this demonstration project until March of this year.

KT applied V2X (vehicle-to-everything) communication technology to 142.6 km sections of 18 major roads including Iye-ro and Samsan-ro in Ulsan City, enabling communication not only between vehicles but also between vehicles and various infrastructures on the road. On Iye-ro, advanced road infrastructure supporting safe driving through information linkage with autonomous vehicles was also established.

KT and Ulsan City installed C-ITS terminals on approximately 2,700 vehicles, including 1,500 local cargo trucks, 900 buses, 65 Bureumi cars (welfare taxis exclusively for severely disabled persons), 200 taxis, 30 official vehicles, and 5 other vehicles. Through this, 28 types of real-time information such as emergency vehicle priority signals, signal violation risk warnings, cargo truck overspeed prevention warnings, and recommended driving time exceedance alerts are provided.

Both parties expect that this system construction will reduce the cargo truck traffic accident rate in Ulsan City by more than 25% by 2024.

KT is developing an AI traffic video analysis solution incorporating artificial intelligence (AI) technology. In addition, KT is developing a traffic DX (digital transformation) solution through real-time data learning related to traffic conditions, traffic accidents, and optimal signal analysis, applying it to C-ITS and ITS projects.

Furthermore, Ulsan City has established a citizen service that allows anyone to use this system via smartphone to receive services such as signal violation warnings and pedestrian alerts. Data will also be provided to companies so that the service can be available on navigation systems and others.

Ulsan City also built a smart crosswalk system applying AI video analysis solutions. This system automatically extends the pedestrian signal if vulnerable road users fail to cross the crosswalk in time.

Choi Kang-rim, Executive Director and Head of KT AI Mobility Business Unit, said, "We will contribute to the spread of autonomous cooperative driving beyond the C-ITS demonstration by utilizing differentiated solutions based on future transportation technologies such as mobility platforms, precise positioning, AI traffic video analysis, and traffic twins."
