  • GPS Navigation to Inform Dangers (E.g. Traffic Signals, Jaywalking) Starting in June

  • Urban Planning News SMG 1320

    The Seoul Metropolitan Government (SMG), together with the Ministry of Land, Infrastructure, and Transport (MOLIT) and the National Police Agency (NPA), is releasing 14 types of digital road infrastructure data, including traffic signals (i.e. signal lights and cycle lengths), jaywalkers, illegally parked vehicles, and more.

    The SMG anticipates that this release of data will go beyond a simple provision of data to the private sector, leading to innovation in the digital transportation industry based on Connected Driving Service,* letting drivers perceive dangerous factors in front of them through digital vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) connections.

    *Connected Driving Service: Automated driving service that drastically decreases traffic accidents and supports autonomous driving based on V2V and V2I technological data exchange of dangers

    This project is to provide GPS navigation companies with digital data on road infrastructure collected through the C-ITS Demonstration Project jointly conducted by the SMG and MOLIT, enabling not only the drivers of buses and taxis equipped with special devices, but drivers of all vehicles to use the cutting-edge connected vehicle service.

    As early as June 2021, the SMG will start its smart navigation services in collaboration with private companies. Through the service, the car navigations will inform drivers of the color of the traffic light ahead and how many seconds are left before the light changes, as well as the risks on the road, such as a pedestrian in a blind spot and the location of parked cars in a tunnel or illegally parked vehicles.

    Now, citizens can not only follow GPS navigation to reach their destination, but also use connected vehicle service for traffic safety for free, being informed of real-time dangers on the road based on the connection with road infrastructure.
    The SMG expects that the universalization of this service will cut the risk of traffic accidents and the waste of fuel caused by the abrupt acceleration or retardation by informing the drivers of the safe driving speed for passing the intersection according to the traffic light as well as reduce traffic accidents due to the negligence of drivers at least by 30%.

    With this public disclosure of traffic data, GPS navigation can predict when vehicles will pass each intersection reflecting the real-time status of traffic lights, which will lead to a much more accurate selection of optimum course to the destination and prediction of the time of arrival at the destination.

    Free road infrastructure data for connected vehicle services

    Up until the present, road infrastructure data, such as the traffic lights and the pedestrian dangers, could be used only by some vehicles, including autonomous driving vehicles equipped with an expensive reader worth about KRW 2 million.
    However, this public disclosure of data will create an environment for using digital data without discrimination, without any separate device, and for anyone who has a mobile phone. Connected vehicle services will now be able to inform drivers of traffic lights ahead and dangerous factors on the road, among more.

    Disclosure of traffic light data of 597 locations in downtown Seoul (including Gangnam) and to be expanded to all six-lane roads by June 2022

    The SMG disclosed traffic light data of 597 locations (intersections) of 22 roads, including roads in downtown Seoul (inside the four main gates), Yeouido, Gangnam, and Sangam, as well as bus-only roads, such as Yanghwa-ro and Sinchon-ro. The data has been collected from infrastructure that was established through the C-ITS Demonstration Project.

    In addition, the SMG will disclose traffic light data of 2,468 locations on all roads with more than six lanes in the city by June 2022, which means that drivers will be able to be informed of the traffic signals they are approaching on a road with more than six lanes. According to the SMG, the number amounts to approximately 45.9 % of all traffic lights in the city.

    The SMG will expand the infrastructure for the opening of traffic signals by thoroughly examining the response of citizens and the effect of reducing traffic accidents. The city will accelerate the digitalization of road infrastructure for detecting jaywalkers in the sections with frequent pedestrian accidents.

    Selection of private GPS navigation companies by February 2021 after online briefing session

    The SMG will select through an open recruitment competent GPS navigation companies that will play a role in providing the service using the disclosed data.

    To this end, the SMG will hold an online briefing session for companies that provide GPS navigation service, including web portal, automobile and communication companies. Among those companies, 3-5 companies will be selected through a fair screening by external judges based on the evaluation of the quality, originality, etc. of the service that will be newly released for citizens.

    Details about the briefing session will be available on the SMG’s Transport Operation & Information Service (TOPIS) website (http://topis.seoul.go.kr).

    Leading the digital transportation industry through disclosure of data with ultra-low latency with the application of latest technologies including 5G

    Exchanging data based on ultra-low latency is a core technology for the transportation industry in the future, including autonomous driving, since if there is a latency of just one second for traffic signal data, data from the past will be of no use.
    For the public sharing of data, the SMG has established an open platform with ultra-low latency where all data are collected every 0.1 seconds through the 5G communication network and exchanged within 0.1 seconds.
