[Asia Economy Reporter Kim Heeyoon] Pintel, an AI video analysis specialist company (CEO Kim Donggi), announced on the 6th that it installed a road incident detection system (hereinafter referred to as the incident detection system) using high-resolution CCTV footage on the recently opened Seobuganseon Underground Road and achieved success in preventing accidents on the opening day.
The Seobuganseon Underground Road is a 10.33 km long, 4-lane tunnel connecting the southern end of Seongsan Bridge to Geumcheon IC. It is the first underground road in Korea to introduce 'multi-lane Hi-Pass.' Additionally, it is a tunnel that enhances efficiency and safety by providing 40 shelters and installing fire extinguishing water spray devices at 5-meter intervals.
Pintel's incident detection system analyzes real-time tunnel footage captured by 180 high-resolution CCTV cameras installed along the 10.33 km tunnel section to automatically detect road incidents such as vehicle stops, wrong-way driving, and pedestrian occurrences. Pintel explained that when such incidents occur, immediate alerts are sent to the control room to secure the golden time for accident response.

On the actual opening day of the Seobuganseon Road on the 1st, a collision accident between a truck and a small car occurred inside the tunnel just 73 minutes after opening. Through the immediate alert from the incident detection system, a caution warning was displayed on the electronic signboards installed at the tunnel entrances and exits, blocking vehicle entry. Following the control room's command, the accident was promptly handled with no casualties.
Traffic accidents inside tunnels are highly dangerous as missing the golden time can lead to multi-vehicle pileups. For example, the accident in the Samae Tunnel on the Suncheon-Wanju Expressway last year escalated into a 32-vehicle pileup, resulting in a tragic 42 deaths.
Besides the tunnel incident detection system, Pintel is also engaged in various traffic solution projects such as building traffic volume measurement devices (VDS) on the Wonju national road and constructing AI digital crosswalks for the Ministry of Land, Infrastructure and Transport. Furthermore, it has recorded achievements in AI-based traffic safety demonstration projects including pedestrian safety initiatives in alleyways and residential roads in Guro-gu and Sejong City apartment complexes, as well as smart intersection technology tests in Sangam-dong.
A Pintel representative stated, "The incident detection system in the Seobuganseon Underground Road detected the collision between a truck and a small car inside the tunnel on the first day of opening and sent an alarm to the control room, preventing a major accident. Based on Pintel’s proprietary lossless analysis technology of high-resolution video, we will continue to demonstrate excellent performance in recognizing small objects and long-distance detection."
