Recently, the U.S. Department of Transportation officially released the C-V2X vehicle networking technology national deployment plan "Saving Lives with Connectivity: A Plan to Accelerate V2X Deployment", proposing to accelerate the deployment of C-V2X vehicle networking in the United States from 2024 to 2036 in three phases: short-term, medium-term, and long-term. By 2036, C-V2X will achieve 100% coverage on highways and 85% coverage at intersections in 75 major cities, with most areas able to provide safety services for vulnerable traffic participants. At the C-V2X vehicle level, six automakers have achieved mass production of vehicles that support driving safety applications, and at least 20 models have realized C-V2X functions.

This move by the United States highlights the importance and value of C-V2X vehicle networking technology in improving traffic safety. The United States hopes to reduce traffic casualties and promote a safer, more reliable and efficient transportation system through its nationwide implementation.

According to data from the World Health Organization, approximately 1.19 million people died in road traffic accidents worldwide in 2021. Especially in recent years, with the increase in the number of cars, road traffic safety issues have become increasingly serious, which is closely related to people's health issues. As an important enabling technology across the fields of automobiles, transportation, and communications, C-V2X vehicle networking can effectively solve the above problems through vehicle-to-vehicle, vehicle-to-road, and vehicle-to-cloud communications and collaborative perception, collaborative decision-making, and collaborative control, breaking through the perception limitations, high computing power on the vehicle side, long-tail scenario challenges, and global traffic optimization challenges faced by single-vehicle intelligence.

01 C-V2X Internet of Vehicles becomes the only de facto standard for Internet of Vehicles worldwide, accelerating global industrial deployment

As early as 2013, Dr. Chen Shanzhi, deputy general manager and chief engineer of China Information and Communications Technology Group, first proposed the concept of C-V2X vehicle networking internationally and established the technical system framework and development route. Since 2015, China Information and Communications Technology Group has begun to work with Huawei and other companies to lead the formulation of C-V2X vehicle networking international standards. Subsequently, in 2018, my country's Ministry of Industry and Information Technology took the lead in issuing spectrum for C-V2X in the world; in 2020, the Federal Communications Commission of the United States revoked the frequency band allocated to DSRC (IEEE 802.11p) vehicle networking and allocated 30MHz of it to C-V2X. The United States' accelerated deployment of C-V2X nationwide is another major move, indicating that C-V2X vehicle networking technology, as a key technology to enable automobile and traffic safety, will be rapidly promoted and applied, ushering in an important stage of large-scale implementation.

In addition to China and the United States further increasing their investment in this field, South Korea also stated in December 2023 that it will use C-V2X vehicle networking to deploy a new generation of intelligent transportation systems. C-V2X vehicle networking has become the only de facto standard for global vehicle networking and is gaining support from more and more countries and regions.

It is reported that the Federal Highway Administration (FHWA) of the United States has provided nearly $60 million in funding to three entities in Arizona, Texas and Utah to promote the deployment of C-V2X technology, enhance the life-saving potential of C-V2X communications, and ensure that related technologies can communicate securely on various devices and platforms without other interference. South Korea plans to achieve a city-level collaborative intelligent transportation system and autonomous driving deployment in Seoul by 2026.

02 my country's C-V2X vehicle-to-everything (V2X) vehicle-road-cloud integrated solution is accelerating its implementation, entering a race mode

In the deployment of C-V2X vehicle networking, my country has formed a good atmosphere of cross-field cooperation, and the industrial ecology is accelerating. Relying on C-V2X vehicle networking, my country is accelerating the deployment of vehicle-road-cloud integration. Under the joint promotion of five ministries and commissions in my country, Beijing, Shanghai, Shenzhen, Guangzhou, Wuhan, Chongqing, Nanjing, Suzhou, Chengdu, and Hangzhou-Tongxiang-Deqing Consortium have been established as pilot cities. Through the "government guidance + market drive" model, a series of coordinated urban application projects are being created to improve the level of urban smart transportation development.

In May this year, Beijing launched a bidding for a 9.94 billion yuan vehicle-road-cloud integration project, followed by Fuzhou, Ordos, Shenzhen, Changzhou, Shenyang and other cities.

At present, various places are entering full-speed mode in promoting the construction of C-V2X vehicle networking. Among them, Beijing plans to carry out construction at about 6,050 road intersections within 2,324 square kilometers; Wuhan plans to promote 13 administrative districts and functional areas such as Wuhan Economic Development Zone and East Lake High-tech Zone to achieve 5G city-wide coverage and intelligent transformation of city intersections; Jinan plans to achieve full coverage of intelligent and networked parking in public areas; Changchun is actively promoting the deep integration of the automotive industry and information and communication technology, and promoting the large-scale demonstration application of intelligent networked vehicles and the exploration of new business models. Chengdu plans to build a total of 13,800 roadside infrastructures by 2026, the network rate of traffic signals in the pilot area will reach 95%, the number of large-scale demonstration application vehicles will exceed 3,000, and the central urban area will be fully open. Changsha will use 1,200 square kilometers in the city as a pilot area to carry out the implementation of "vehicle-road-cloud integration" technology and large-scale application of intelligent networked vehicles. It is planned to realize full-area open testing of urban roads by 2026, covering demonstration application scenarios such as functional unmanned vehicles, unmanned intelligent networked vehicles and highways.

03 The process of C-V2X vehicle networking is accelerating, and the introduction of C-NCAP may become an important starting point for the development of intelligent connected vehicles

In terms of promoting C-V2X on vehicles, more than a dozen Chinese automakers have released more than 20 C-V2X pre-installed mass-produced models, and some automakers have clearly stated that they will equip their entire series with this technology. According to the database of Zoss Automotive Research, the pre-installation rate of C-V2X on passenger cars will be about 1.2% in 2023, and the pre-installation scale will exceed 270,000 vehicles. It is expected that a large-scale installation period will come in 2026-2027, and the pre-installation rate is optimistically predicted to exceed 9%.

Public information shows that NIO plans to equip its NT3 platform models for mass production in 2025 with C-V2X, with an estimated installation volume of 1.5 million vehicles in five years; BMW Brilliance plans to deploy 130,000 sets of pre-installed C-V2X on all its models in 2024; as Ford, the first company to deploy V2X in the Chinese market, the company's C-V2X vehicle-road collaborative service has been implemented in seven cities across the country, including Guangzhou and Wuhan, with a cumulative actual service user base of more than 12,000.

It is worth mentioning that my country's new car crash assessment program C-NCAP has taken the lead in introducing C-V2X technology to achieve active safety and promote C-V2X vehicle-side applications, which has also had an important impact on the global NCAP system. In addition, in order to promote the formulation of standards in the field of network functions and applications, my country's Automobile Standardization Technical Committee actively promotes the standard verification test of the "Technical Specifications for Safety Warning Systems of Intelligent Networked Vehicles Based on Direct Communication Technology" to ensure technical safety and support the implementation of technical applications.

In the future, relying on the pilot cities of vehicle-road-cloud integration, my country will further deepen the layout of the C-V2X industry and significantly increase the coverage rate of C-V2X infrastructure and vehicle-side penetration rate, which will be of great significance to promoting the innovative development of intelligent connected vehicles. With large-scale applications, the value of C-V2X vehicle networking will gradually emerge, gradually play a role in improving road safety, optimizing traffic flow and improving vehicle operation efficiency, and effectively promote the overall upgrade of urban transportation systems, helping to create a safe, comfortable, efficient and green travel experience.
