SEOUL -- Level 4 autonomous cooperative driving technology will be demonstrated on a real urban road with intersections and traffic signals. Infrastructure such as roadside base stations and precision electronic maps has been prepared to verify driving and communication performance using a total of 10 connected and self-driving cars.

Unlike autonomous levels 1, 2, and 3 that assist human drivers to conveniently reach their destinations, level 4 is fully autonomous. A level 4 self-driving vehicle does not require a driver or a steering wheel. It navigates around places by communicating with on-road structures such as traffic lights and pedestrian crossings and other vehicles.

The demonstration of level 4 autonomous cooperative driving technology will be conducted for two days on October 27 and 28 on the 1.2 km uncrowded and straight section of a road in Hwaseong City, about 30 kilometers (18 miles) southwest of Seoul, according to the Ministry of Land, Infrastructure and Transport, which launched a state project involving 24 state bodies, private companies and college research teams.

"The results of this study are meaningful in that it introduced level 4 autonomous cooperative driving technology that can be operated on complex urban roads," Kim Jung-hee, a ministry official in charge of automobile policy, said in a statement on October 26. "We will actively support private technology development to develop level 4 self-driving cars at a more advanced level and establish an autonomous cooperative driving environment."

The event will showcase three-year research results on technologies that support autonomous driving through vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication. A scenario was drawn up by combining traffic conditions that can occur on urban roads such as a dilemma zone, blind spots, an unexpected situation, construction sites, and emergency vehicles.

An autonomous vehicle uses V2I technology to directly communicate with objects such as traffic lights and traffic cameras to navigate safely while using V2V to directly communicate with other nearby vehicles. Both technologies do not require the self-driving car to visually recognize objects and other cars using optical devices.
