In recent years, the construction of China's Vehicle-Road Coordination Demonstration Zones has significantly accelerated. Over 500 kilometers of urban roads have already undergone intelligent upgrades, injecting strong momentum into the development of smart transportation. Take Chengdu, Sichuan, as an example—sections of Chengdu’s Ring Expressway, Second Ring Expressway, and parts of the Chengyi Expressway have taken the lead in piloting vehicle-road coordination applications tailored for specific scenarios. By deploying advanced intelligent sensing devices such as millimeter-wave radar and high-definition cameras, Chengdu has established a comprehensive holographic perception network spanning 85 kilometers. This system enables real-time monitoring of road conditions and seamlessly integrates with navigation platforms to deliver precise early warnings, allowing accidents to be detected within seconds and addressed within minutes. As a result, traffic flow during peak morning hours has increased by 12%, average vehicle speeds have risen by 10%, and congestion durations have been reduced by 25%.
Driven by the dual forces of policy support and technological breakthroughs, vehicle-road collaboration is expanding from isolated demonstration projects to full-scale, city-wide coverage. The Ministry of Industry and Information Technology, along with four other departments, jointly announced a list of pilot cities for "vehicle-road-cloud integration" applications, including 20 cities such as Chongqing and Shenzhen. These cities are explicitly required to achieve full 5G network coverage and deploy road-side equipment on a large scale. Meanwhile, Shanghai and Shandong Province are simultaneously advancing smart highway initiatives—Shandong’s Jiwei Expressway has already installed 11,000 sets of intelligent sensing devices, enabling features like lane-level navigation and seamless, non-deceleration tunnel passage, resulting in a significant drop in accident rates.
As technologies like 5G-A and edge computing mature, vehicle-road collaboration is transitioning from pilot verification to large-scale commercial deployment, laying the groundwork for the commercialization of autonomous driving and propelling China's intelligent transportation system toward a more efficient and safer future.
