Financial support for V2X (Vehicle-to-Everything) technology is essential to improve traffic safety and advance autonomous driving development, according to a new policy paper.
The Global Policy Research Institute, an affiliate of AI law and regulatory platform company Codit, released an issue paper titled "Policy Tasks for Global V2X Expansion and Building Safer Transportation Systems" on Sunday.
V2X is a wireless communication technology that enables vehicles to share real-time information with other vehicles, road users, traffic signals, and road infrastructure, allowing them to recognize and respond to surrounding conditions.
The Ministry of Land, Infrastructure and Transport's next-generation Cooperative Intelligent Transport Systems (C-ITS) pilot project, launched in 2015, demonstrated significant results. The Sejong-Daejeon corridor (90.7 km) equipped with V2X services saw approximately 20% reductions in average accident frequency and casualties over five years. Last year, V2X-based services operated reliably in real road environments, bringing technical verification to its final stage.
"However, the policy momentum for V2X adoption has weakened due to the absence of follow-up procedures and budgets for nationwide expansion," the institute said. "Such policy delays could lead to structural gaps not only in traffic safety but also in future mobility industry competitiveness."
The institute proposed three policy priorities for transitioning to a V2X-based transportation system: establishing V2X expansion foundations through financial support and institutional frameworks; strengthening the importance of V2X technology in the Korea New Car Assessment Program (K-NCAP); and ensuring continuous management of V2X standard policies.
The institute specifically called for large-scale deployment of V2X roadside units (RSUs) and distribution of V2X onboard units (OBUs) across all public vehicles.
