In recent years, my country's policy framework in the field of smart travel and vehicle-road-cloud integration has been gradually improved, and smart lamp poles and their core components, LED lamp pole screens, as new urban infrastructure, are becoming key nodes for promoting the implementation of intelligent transportation systems. This integration not only reflects the technological innovation under policy guidance, but also shows the leapfrog development of urban governance from "single function" to "global perception".

According to the "Policy Research Report on Smart Travel and Vehicle-Road-Cloud Integration", my country's smart transportation policy system presents the characteristics of "multi-level coordination". The Ministry of Housing and Urban-Rural Development clearly stated in the "Guiding Opinions on Comprehensively Promoting the Construction of Urban Integrated Transportation Systems" that it is necessary to promote the "intelligent and green" upgrade of transportation infrastructure. Smart lamp poles, as multi-functional integrated poles, are the product of this policy orientation. By integrating 5G base stations, environmental sensors, security monitoring, LED information display screens and other equipment, it has achieved the intensive goal of "one pole for multiple uses" and has become the "nerve endings" of urban roads.

LED light pole screens not only undertake the functions of traffic guidance and public information release, but also improve the efficiency of urban services through dynamic advertising and emergency notifications. Shenzhen has deployed smart light poles to link LED screens with traffic signal systems, issue congestion warnings in real time, and improve the efficiency of intersections by 30%. This "hardware + data" collaborative model perfectly meets the policy requirements of "increasing roadside unit coverage" in vehicle-road-cloud integration.

The large-scale application of smart light poles and LED light pole screens provides physical carriers and data entry for vehicle-road-cloud integration. At the technical level:

1. Perception layer: The cameras, radars, temperature and humidity sensors and other equipment carried by the light poles can collect road environment data in real time, and upload them to the cloud through edge computing nodes to support the global decision-making of autonomous driving vehicles.

2. Communication layer: Smart light poles that integrate 5G base stations and Wi-Fi hotspots solve the "last mile" problem of vehicle network communication and ensure low-latency interaction between vehicles, roads and clouds.

3. Interaction layer: LED light pole screens serve as information output terminals, which can dynamically display traffic status, navigation prompts and even personalized advertisements, forming a closed loop of "people-vehicle-road" two-way interaction.

Taking Beijing's high-level autonomous driving demonstration zone as an example, its 160 square kilometers have achieved integrated coverage of "vehicle-road-cloud-network-map". The holographic perception data of smart light poles is distributed to vehicles in real time through the cloud control platform, extending the perception distance of single vehicles from 300 meters to several kilometers.

Practical path: local pilot and model innovation

Local policies show differentiated innovation in the collaboration between smart light poles and vehicle-road-cloud:

Beijing: Through "limited legislation" to loosen up technology, allowing autonomous driving vehicles to be tested in specific areas, and at the same time using smart light poles as a fulcrum to build a closed loop of "technical innovation-scenario application-institutional guarantee".

Shanghai: Promote 5G-A network upgrades, link smart light poles with smart bus stops and parking systems, and form a demonstration model of "data access to the entire road, cloud network connection to the entire vehicle".

Guangzhou: Adopting "1+N" collaborative legislation, with the "Regulations on the Innovation and Development of Intelligent Connected Vehicles" as the core, clarifying the boundaries of rights and responsibilities of smart light poles in data sharing and safety supervision.

It is worth noting that the business model of LED light pole screens is also breaking through in exploration. Some projects in Chongqing adopt the "government platform + enterprise operation" model, with media companies responsible for advertising placement, and the revenue is fed back to equipment maintenance to form a sustainable ecological cycle.

By 2030, my country's vehicle-road-cloud integration industry is expected to bring an increase in output value of more than 2.5 trillion yuan. As the "capillaries" of the smart light poles and LED light pole screens, they will continue to exert their strength in the following directions:

- Global perception: through satellite networking (such as Geely's future travel constellation) and ground light poles, an integrated air-space-ground monitoring network will be built;

- Low-carbon transformation: combining photovoltaic power generation and energy storage technology to achieve self-sufficiency in light pole energy;

- Service extension: expand new scenarios such as medical emergency and unmanned delivery, and promote the upgrade of smart cities from "traffic management" to "full life cycle services".

The popularization of smart light poles and LED light pole screens is not only a microcosm of technological iteration, but also the result of collaborative innovation in policies, industries, and society. Under the framework of vehicle-road-cloud integration, these "thinking street lamps" are quietly reshaping the urban texture and opening up a Chinese-style path for smart travel that combines efficiency and warmth.
