    SEOUL, SOUTH KOREA, January 25, 2021 – The Seoul Metropolitan Government announced to provide navigation service providers with its 14 types of digital road infrastructure data in cooperation with the Ministry of Land, Infrastructure and Transport, and National Police Agency. The data include traffic signals, such as the color of a traffic light ahead and its remaining seconds, jaywalkers, and locations of illegally parked or stopped vehicles.

    The city believes this will be more than a simple provision of data and lead to an innovative transformation of the digital transport industry by making vehicles constantly access the “Connected Driving Service” using the Vehicle-to-vehicle (V2V) and Vehicle-to-Infrastructure (V2I) connections, which provide a heads-up to drivers.

    The digital road infrastructure data collected as part of the C-ITS project implemented by the Seoul Metropolitan Government in partnership with the Ministry of Land, Infrastructure and Transport will be provided to navigation service providers enabling not only 1,600 buses and 100 taxis equipped with a particular device but also all drivers to use the advanced connected service.

    “Smart Navigation Service” launched as early as June to provide a heads-up on risks on the road ahead

    The city government plans to launch the “smart navigation service” as early as June in cooperation with the private sector. The service will inform users of the color of a traffic light ahead with remaining seconds, pedestrians in a blindspot, locations of illegally stopped or parked vehicles in a tunnel. All citizens will access the safety-oriented connected service providing a heads-up on risks on the road ahead through the real-time connection with the road infrastructure and the existing navigation service for free of charge.

    The Seoul Metropolitan Government expects the new service to reduce accidents or wasted fuel resulted from rapid acceleration or deceleration by informing drivers crossing intersections of the safe speed on time and cutting down on traffic accidents caused by driver’s carelessness by more than 30 percent.

    It also expects that the service users will be able to use more accurate information on the best route and time to a destination as they can even predict when to cross an intersection based on real-time traffic signal data.

    The connected service all citizens can access for free of charge without having particular devices

    Thanks to the new service, all citizens can access the connected service on their smartphone for free of charge without having special devices.

    The traffic signal data on 597 intersections to open and that on 2,486 spots on 6-lane or larger roads to be provided by June next year

    Initially, the city will open the traffic signal data on 597 intersections on 22 roads (151.0km)
    with a dedicated bus lane in downtown, Yeouido, Gangnam, Sangam, Yanghwa-ro, and Shinchon-ro. The data are collected from infrastructure installed through the C-ITS project.

    According to the city government, traffic signal data on 2,486 spots on 6-lane or larger roads will be provided by June next year so that drivers can access heads-up information on traffic signals ahead. It means 45.9 percent of traffic signals of the entire traffic control devices throughout the city will be shared.
    * Data on 1,883 out of all 4,098 spots in the city will be open to the public by June 2022.

    After closely reviewing citizens’ responses and the impact on reduced traffic accidents, the city is planning to provide data on all roads throughout the city and digitalize infrastructure on roads with frequent jaywalks.

    The online briefing session held on January 29 to select service providers

    The city will hold an online briefing session for navigation service providers, including portals, carmakers, and communications service providers, on January 29 and have a committee of all outside members evaluate the new service’s quality and originality. Aft that, it will finally select three to five providers.

    Seoul to lead the digital transport industry innovation by opening up the ultra-latency data using advanced technologies

    The city realized the open platform with ultra-low latency for the new service, collecting data every 0.1 (100 ms) second and making all data exchanged within 0.1 second through 5G network.

    Even one-second latency makes traffic signal data useless, data exchange with ultra-low latency is considered a core technology for the future transport industry, such as autonomous driving.

    Deputy Mayor for City Transportation Hwang Bo-yeon said, “With launching the new service, Seoul will further develop the ultra-latency connected technology digitally connecting vehicles and road infrastructure through 5G network to lead the future transport industry, including the autonomous driving.”
