The Seoul Metropolitan Government and SKT will jointly develop the real time super precision road map indispensable to AV by the next year. The super precision road map leverages cutting edge technologies such as 5G and AI and upgrades the accuracy and speed of road situations against the existing 3D (HD map) precision map by a notch.
While the existing 3D precision map updated road situations manually, the upcoming super precision road map incorporates road information as well as continuous changes including sunken roads and construction information on a real time basis. As the vehicles transfer the image data collected using 5G telecommunications network to a central server, AI will identify changes on its own and produce maps automatically.
The precision road map transfers the information, such as traffic light, bridges, road stop lines, which allows AI vehicles to find their way to the destination into 3D map. Until now vehicles with various devices installed shall collect and analyze the images (MMS measures) driving on the road which posed limitations against incorporating the frequently changing real time road situations such as lane changes, sunken roads, constructions and road sign changes. MMS (Mobile mapping system) is a system which integrates a variety of sensors including cameras and GPS devices and is installed in vehicles to support driving as well as to obtain GPS of geographical features and visual information.
Particularly the Seoul Metropolitan Government plans to install ADAS (Advanced driver assistance system) vision sensors to 1,700 vehicles (1,600 Seoul buses and 100 taxis) and use them as probe vehicles. ADAS informs the driver of the possible forward collision, lane departure and pedestrian risk ahead by analyzing the images collected through sensors.
The super precision road map shall be produced for the C-ITS (next generation smart traffic system) planning sections. This will cover 121.4 km composed of 12 expressways including Sangam DMC, Yeouido, Gangnamdaero, Dobong, Mia-ro, Suseak and Sungsanro. Seoul plans to complete the map production over Sangam DMC section by the end of this year and finish up all the rest by the next year. The city government and SK Telecom will verify the real time super precision road map over the 121.4 km first and then roll it out to cover the full city.
Furthermore, once accuracy is proven through sufficient verification process the city government will assist developing the related industry in consultation with the Ministry of Land Infrastructure and Transport. Also it will actively work with the public and private Committee for Joint Developing System of precision road map, launched last month to support AV technology development.
A total of 17 institutions including the Ministry of Land, NGII (National geographical information institute) Korea expressway corp. Hyundai Motor Group, Ssangyong Motor Company, Mando, SKT, KT, LGU+, Hyundai MNSoft, INAVI systems corp. Navi Automotive systems, Kakao, LG Electronics, Naver Labd, Socar, and Kakao Mobility are taking part in the committee.
