The development of `smart road` is speeding up as self-driving cars are quickly being commercialized. Smart road is an intelligent road infrastructure that is able to recognize and judge the external environment and support efficient operation and safety of all cars. A very precise and dynamic map accurately tells the current location of the car, and communication services are provided seamlessly to support the self-driving car to travel safely and accurately.
The system will be piloted in the Seoul-Singal-Hobub, in the distance of 41 km, which will be selected by the Ministry of Land, Infrastructure and Transport next year. It is expected that traffic accident will be greatly reduced in the situation where self-driving car and general car will mixed on the road.
The Ministry of Land, Infrastructure and Transport is conducting the `Smart Self Cooperative Road System Construction Project`, a research project to develop a future road system suitable for a fully self-driving car, under the supervision of Korea Highway Corporation.
The project includes △ a detection system that is able to recognize road conditions, △ a position correction system to provide accurate position of the car, △ a wave (WAVE), and V2X (Vehicle to Everything) technology that applies mobile communication technology to inform the car, △ the development of a dynamic information system (LDM) system that systematically DBs all information necessary for self driving and provides them to cars in real time is the key.
Korea National Railroad Corporation is developing special technologies with companies such as Hanil STM, etc. to focus on developing LDM technology as the core of infrastructure for self driving roads. LDM is a technology that is able to provide real-time collection, storage and management of cars, weather, and construction information to cars by applying 3D precision electronic maps.
The information that is provided by the LDM is divided into four steps, from static information such as lane information, stop lines, and road markings to dynamic information such as temporal control, unexpected situation, car location, and driving. The car-related information is updated in seconds and highway status is updated in minutes, static information, on the other hand, can be updated in hours or monthly cycles.
Meanwhile, Hanil SDI is involved in road infrastructure system construction, road infrastructure facility management, LDM monitoring and data analysis research through construction and operation of an integrated operation center. The GPS positioning error is being reduced to less than 0.5m from the existing 10 ~ 15m to one-half of the original position in order to allow the self-driving car to accurately grasp its position.
It also implements a hybrid (wave + mobile communication) communication method that complements limited communication capacity and infrastructure limitations. Wave is a telecom service that is tailored to the car through modifying the Wi-Fi and combines wave and mobile communication (LTE) services to realize seamless communication.
Korea Expressway Corporation is scheduled to be piloted in the 41km distance of the Seoul-Shingal-Hobub, which is the next self-driving car test service area, starting from the technology and system under development. It is expected that traffic accidents will be reduced by 40 ~ 46% in the situation where self-driving cars and ordinary cars are mixed when this infrastructure is applied to roads.
The Ministry of Land, Infrastructure and Transport is expected to build a next-generation intelligent transportation system (C-ITS) focusing on the metropolitan area with the aim of fully self-driving operation of the city road by 2035.
The system will be established in foggy areas, accident-prone areas, junctions and junctions along with traffic-weakened areas. Besides, it is a plan to allow level 4 (fully self-driving) operation on all roads by 2045. During this period, the self-driving car will increase to about 30% of all registered cars.
Choi In-gu, head of self-cooperative driving road system of Korea Expressway Corporation, explained, "When a road infrastructure that is friendly to self-driving cars is built, very precise situation-specific information will be provided in case of a frontal accident so that a safer driving environment will be implemented by preventing secondary accidents.”
Park Yeon-seop, head of Hanil STM Research and Development Center, revealed "We plan to develop the wave base station that covers road networks nationwide to provide seamless information exchange between cars and road infrastructure.”
