Electronic identity cards, internet hospitals, smart homes... The new products and scenarios created by digital technology are accelerating their integration into people's daily lives. The recently issued "Overall Layout Plan for the Construction of Digital China" requires "popularization of digital life intelligence". How to build a better new landscape of digital life, allowing more people to share a comfortable and convenient digital life? Starting from today, this version will launch a series of comments to explore these issues and look forward to a better future in the digital society. ——At 6:30 am, Xiao Xinhua, a bus driver from Xiamen, Fujian, drove the No. 37 shuttle bus to the railway station; After arriving at the station, he set off again for the first pier, and the route sign had now changed to the M9 connecting line. Same vehicle, different routes. The "flexible public transportation" model in Xiamen relies on big data analysis of station traffic and flow direction, effectively integrating driver and vehicle resources, optimizing transportation capacity allocation, and achieving that public transportation goes wherever there are many passengers. Some people say that the transportation industry is moving from the era of "transportation capacity" to the era of "computing power", from horse drawn carts to steam locomotive to smart cars, and the public transportation and travel services will be greatly changed. Optimizing transportation capacity through data computing power is not limited to intelligent transformation of vehicles. It can also transmit data from various aspects such as people, vehicles, lines, stations, roads, and parking lots to the "smart brain" of urban transportation through cameras and LiDAR on the road, forming a hierarchical decision-making plan, thereby achieving overall optimization and fine operation of public transportation. Providing passengers with a ride is a fundamental issue in public transportation, while providing passengers with a better experience requires significant efforts in smart transportation. In Wuhan, Hubei, many buses are equipped with panoramic monitoring systems to eliminate driver visual blind spots and make it safer to ride the bus; In Changsha, Hunan, when smart customized buses pass through intersections, signal lights are given priority to release, saving travel time and making it faster to take the bus; In Haikou, Hainan, the positioning system helps passengers retrieve lost items time and time again, making it easier to travel by bus... Empowered by digital technology and filling in service gaps, public transportation will combine advantages such as affordability, energy conservation, environmental protection, convenience, and comfort, and will definitely attract more people to choose it as a travel choice. The advantage of smart transportation lies not only in optimizing the frequency of flights to improve the travel experience, but also in providing extended services through smart bus stops and other means to meet the diverse needs of passengers. Taking the electronic bus stop sign as an example, it can integrate many service functions. In addition to displaying weather and route information, station arrival reminders, it can also provide wireless network, free charging, and other services. At night, it can also better ensure passenger safety through video monitoring, SOS one click call for help, and other services. These improvements are very friendly to some special groups. A passenger exclaimed, "Now this new type of bus stop sign is very good, making it convenient for middle-aged and elderly people to travel." With the progress of digital technology and the implementation of more new application scenarios, there is still greater room for imagination in improving public transportation services. Not long ago, the Xiamen Urban Public Transport Comprehensive Intelligent System Technology Demonstration Project passed the acceptance of the Ministry of Transport. Rapid transit can achieve precise stop at the platform without manual operation; When the two cars are not at a safe distance from the front car, activate the collision avoidance system; The intelligent guidance system for urban public transportation calculates the optimal power plan, assisting in
