In the wave of technology in the 21st century, the application of autonomous driving technology is gradually changing our urban living landscape and leading the new direction of future smart city development. Whether it's engineers from technology companies, urban planning experts, or ordinary citizens, they are all full of expectations for autonomous driving technology. Because when autonomous driving can truly integrate into various aspects of urban development, future cities will inevitably present a more green and intelligent appearance. Autonomous driving technology, as a product of the combination of artificial intelligence and the automotive industry, is changing the face of cities with its unique charm. Whether on domestic or overseas social media, "autonomous driving" is a hot topic among netizens. Many netizens share their experience videos of riding autonomous vehicles, becoming a "hot item" with over 100 million clicks. These 'flows' not only showcase the charm of autonomous driving technology, but also indicate a profound transformation in urban landscape and traffic management. In terms of traffic management, autonomous driving will make urban management more "proactive". Traditional traffic management mainly relies on the on-site command of traffic police and the setting of traffic signals, which is inadequate in dealing with emergencies. The introduction of autonomous driving technology has made traffic management more intelligent. Through big data analysis, autonomous vehicles can perceive road conditions in real time, plan routes in advance, and avoid congestion and accidents. At the same time, traffic management departments can also accurately predict traffic flow through data collected by autonomous vehicles, thereby optimizing the setting of traffic lights and improving road traffic capacity. Urban planning is a complex and arduous task in urban management, and the emergence of autonomous driving technology provides new possibilities for more rational urban planning. In the past, urban planning mainly focused on responding to rapid population growth and urban expansion, with emphasis on incremental planning such as urban infrastructure construction and road network expansion. Nowadays, the new problems faced by cities have prompted the focus of planning to shift towards optimizing the utilization of existing resources. Autonomous driving technology may be the key to breaking the deadlock. For example, autonomous vehicle can more accurately control the position in the lane, reducing the need for safe spacing between vehicles. Therefore, urban planning can reduce lane width and free up more space for other purposes, such as adding bike lanes, sidewalks, or green belts, without reducing traffic capacity. In addition, the driving role of autonomous driving in public services is also worth exploring. Nowadays, public services often rely on fixed facilities and personnel, while autonomous vehicles can serve as a mobile public service carrier to meet the diverse needs of citizens. Of course, the relationship between autonomous driving and urban management is not one-way. The development of autonomous driving technology not only provides diversified solutions for urban management, but also requires support and cooperation from urban management. The government needs to formulate relevant laws and regulations to promote the development of the autonomous driving industry. Currently, some regions are making efforts towards the gradual development of autonomous driving. For example, Beijing has promoted the legislative work of the Regulations on autonomous vehicle in Beijing, and has planned and built a high-level autonomous driving demonstration zone in Yizhuang. Hangzhou has issued the "Hangzhou Intelligent Connected Vehicle Testing and Application Promotion Regulations", becoming the first provincial capital city in China to legislate for the on road use of intelligent connected vehicles. How to further promote each other between autonomous driving and urban management is not only something that governments and enterprises need to face, but also requires the participation of more social entities. Citizens need to enhance their understanding of autonomous driving technology; The media needs to play a role in guiding public opinion and creating a good social atmosphere. The emergence of autonomous driving technology has brought new opportunities and challenges to urban management. Through the positive interaction between autonomous driving and urban management, we can create a smarter, more efficient, and livable urban environment. Let "smart cars" and "smart cities" travel in both directions. (New Society)
