China’s Path to Large‑Scale L4‑L5 Autonomous Driving: Baidu CEO’s Vision
In a newly released audio course, Baidu founder Li Yanhong outlines how China could become the first country to commercialize large‑scale L4‑L5 autonomous driving, emphasizing vehicle‑road collaboration, AI‑enabled traffic control, and the broader impact on intelligent cities and society.
On February 24, Baidu’s founder, chairman, and CEO Li Yanhong launched his audio series "Intelligent Transportation in 7 Lectures" on the DeDao app. Recorded by Li himself, the course covers hot topics across autonomous driving, vehicle‑road collaboration, mapping, parking, and highways, marking his first public sharing of views on the future of large‑scale transportation.
Vision of Intelligent Transportation
Li states, "Autonomous driving is the starting point; the ultimate goal is intelligent transportation, intelligent cities, and even an intelligent society." He believes that the convergence of smart vehicles and smart roads will be the core technology for future urban mobility.
Market Outlook and China’s Advantage
Industry reports predict that by 2030 China’s autonomous‑vehicle sales will reach US$230 billion (≈¥1.5 trillion), making it the world’s largest market. With strong policy support and growing social demand, China is positioned to lead the global rollout of L4‑L5 autonomous driving.
Technology Route: Vehicle‑Road Collaboration
Two main approaches dominate autonomous‑driving research: vehicle‑centric intelligence and vehicle‑road collaboration. Li emphasizes Baidu’s commitment to the latter, arguing that road‑side intelligence can reduce accident rates by 99 % and shift costly functions from the vehicle to infrastructure, accelerating commercial deployment.
Through vehicle‑road collaboration, traffic signals dynamically adjust based on real‑time data from road‑side cameras and sensors, enabling smoother flows and higher safety.
Baidu Apollo Achievements
Baidu’s Apollo platform boasts over 21 million kilometers of test mileage and a mature autonomous‑driving solution. Its passenger‑service platform “Luobo Kuai Pao” operates in seven major Chinese cities, offering real‑world testing and ride‑hailing services.
Case Study: AI‑Enabled Traffic Control in Baoding
In Baoding’s Qiliu Road, the deployment of Baidu’s AI traffic‑signal system created a "green wave" that let vehicles pass through 12 consecutive intersections without stopping, cutting average travel time by 20 %.
Efficiency Gains and Societal Impact
Modeling suggests that vehicle‑road collaborative intelligent transportation can improve traffic efficiency by 15‑30 %. Li predicts that within five years, first‑tier Chinese cities could lift purchase and travel restrictions, and within ten years, congestion could be largely resolved.
Comprehensive Intelligent Transportation Solutions
Baidu’s portfolio now includes intelligent networking, smart traffic management, intelligent highways, and smart parking, already deployed in over 50 cities nationwide.
National Policy Alignment
The 2019 "Outline for Building a Strong Transportation Nation" aims for a fully developed transportation powerhouse by 2035, with intelligent, safe, green, and shared mobility. By mid‑century, China seeks to rank among the world’s leaders in transportation intelligence and sustainability.
Conclusion
Li reiterates that autonomous driving is merely the entry point; the ultimate goal is an integrated ecosystem of "smart cars" and "wise roads". Baidu’s strategy leverages AI, 5G, and cloud computing to forge a uniquely Chinese model for high‑quality, intelligent transportation development.
