Connected Vehicle (V2X) Technology

(1) What is Connected Vehicle (V2X) Technology?

  • Connected Vehicle technology refers to the low-latency communication system between vehicles and vehicles, vehicles and pedestrians, vehicles and road infrastructure, and vehicles and networks. Through the real-time information transmission in the Internet of Vehicles system, people, vehicles and road infrastructure are connected and coordinated, and road users receives reports and warnings in real time to enhance road safety and assist driving. At the same time, the Connected Vehicle technology can be applied to real-time traffic monitoring, accident management, and route planning to improve traffic efficiency. In the long run, Connected Vehicles can better cooperate with the development of autonomous driving technology, assist autonomous driving in detecting hidden dangers and improve road safety.

(2) What is the goal of this project?

  • The Hong Kong government proposed in the “Hong Kong Smart City Blueprint” published in 2017 that the government will cooperate with the development of Connected Vehicles technology, with a view to eventually introducing autonomous vehicles that incorporate Internet of Vehicles technology. In the “Hong Kong Smart City Blueprint 2.0” published in December 2020, the government also reiterated that it will cooperate with the technology and industry development of the Connected Vehicle (V2X) and autonomous vehicles, with a view to eventually introducing autonomous vehicles equipped with V2X.

  • ASTRI started to develop Connected Vehicles technology in 2016, and successfully conducted road trials at the Hong Kong Science Park for the first time in June 2017.

  • In order to comprehensively study the application scenarios of the Connected Vehicles technology in Hong Kong’s roads, and how to plan the network and infrastructure required for the application, ASTRI has been in close contact with the Transport Department from November 2019, through the Innovation and Technology Fund of the Innovation and Technology Commission. Carry out research and test projects related to the Connected Vehicle (V2X) system technology.

  • The site of the pilot project is planned to be about 14 kilometers between the Hong Kong Science Park and Sha Tin City Centre, and the project has received the support of the Sha Tin District Council, Transport Department, Highways Department and other relevant government departments.

(3) Why choose Shatin?

  • Located in Sha Tin Science Park, ASTRI was established by the government in 2000 and operated under the supervision of the Innovation and Technology Commission. We started to develop the Connected Vehicles technology in 2016, and successfully conducted a road test at the Hong Kong Science Park for the first time in June 2017. In order to more comprehensively study the application scenarios of the Connected Vehicles technology in Hong Kong’s roads, as well as the required network and infrastructure equipment, this Connected Vehicle field trial project is planned to start from the Science Park, along the Shing Mun River in Shatin, and via Dayong Bridge Road to Shatian City total 14 kilometers in between, the technology tests will be conducted back and forth.

  • The roads selected for this trial cover different road environments in Hong Kong, including highways, roundabouts, traffic light intersections, pedestrian crossings, etc., which are very suitable for the realization and testing of different connected vehicle road safety application scenarios, and can be applied to the future development of connected vehicle technology.

  • If the application of the Connected Vehicle is fully implemented in the future, the equipment installed in Sha Tin District can benefit the residents of Sha Tin District in advance.

 

(4) Will the test period cause inconvenience or safety issues to the public?

  • We have carried out detailed planning according to the needs of the test project and are absolutely confident that it will not cause inconvenience or safety issues to the residents of the district during the test period.

 

(5) When will the test start? How long is the entire test period?

  • The test is expected to start in early 2021 and will last for one year.

 

(6) What data will the car networking test system receive and process?

  • The trial only involves specific test vehicles. The Connected Vehicle(V2X) system will only receive, process or release information about specific test vehicles, such as vehicle speed, GPS location, direction, braking status, indicator light status, dead fire light status, etc. Other vehicles and pedestrians It will not and cannot be connected to the car Connected Vehicle(V2X) Network system.

 

(7) Will there be radiation problems with connected vehicle roadside equipment?

  • The Connected Vehicle trial has obtained a trial permit from the Office of the Communications Administration; it is necessary to ensure that the specifications, information and transmission safety of the telecommunications equipment (roadside equipment and on-board devices) used in the test are in compliance with telecommunications management standards and requirements , And will not affect the citizens.

 

(8) How to ensure the information security and privacy issues of the car networking system?

  • The trial only involves specific test vehicles, and other vehicles and pedestrians will not and cannot connect to the Connected Vehicle Network system. All car networking equipment installed on the lamp post does not have a video lens, and the Network system, roadside equipment and on-board devices only do real-time information processing and will not store data. The relevant test will only receive, process or distribute information about specific test vehicles, and the relevant information will be processed in real time and will not be stored.

 

(9) The future development direction of car networking technology in Hong Kong?

  • The Transport Department will refer to the results and effectiveness of the trial result to explore how the Connected Vehicle technology can be applied in Hong Kong, and propose feasible development directions and consider how to implement such technology in designated public places and roads. At the same time, the Transport Department will refer to the latest developments and experience of regulation of such technology to move Hong Kong to further enhance Hong Kong smart mobility competence.
