With the rapid development of the intelligent connected vehicle industry, Vehicle‑Road‑Cloud Integration has become a key direction for advancing intelligent and efficient transportation systems. In early July 2024, China's Ministry of Industry and Information Technology (MIIT) and four other central government departments jointly issued the "Notice on Announcing the List of Pilot Cities for Intelligent Connected Vehicle 'Vehicle‑Road‑Cloud Integration' Applications," designating 20 cities (or city clusters) – including Beijing, Shanghai, Shenzhen, Guangzhou, Wuhan, Changsha, Chongqing, Nanjing, Suzhou, Chengdu, and the Hangzhou‑Tongxiang‑Deqing consortium – as the first batch of pilot cities for this initiative. This marks a new phase of large‑scale implementation and development for Vehicle‑Road‑Cloud Integration.
Shanghai MRDCom Co., Ltd., a leading enterprise in the R&D, production, and service of industrial products, has played a significant role in the Vehicle‑Road‑Cloud project in Shanghai's Fengxian District with its MRD‑branded TSN (Time‑Sensitive Networking) switches. Featuring deterministic transmission, low latency, and high reliability, these switches fully meet the project's requirements and have provided a solid guarantee for its successful implementation.

What is Vehicle‑Road‑Cloud Integration?
Vehicle‑Road‑Cloud Integration refers to the convergence of the physical and information spaces of people, vehicles, roads, and clouds through next‑generation information and communication technologies, enabling safe, energy‑efficient, comfortable, and highly efficient operation of intelligent connected vehicle transportation systems.
In simple terms, it allows "busy vehicles" to run on "smart roads" with the coordination of the cloud.
Challenges and Requirements of Vehicle‑Road Integration
(1) Bandwidth and Stable Transmission Requirements
Long routes, dispersed locations, and the need to access a large number of video surveillance and other terminal devices result in a dramatic increase in throughput and a huge demand for bandwidth resources.
Packet loss and latency issues are common during transmission, affecting data stability.
Some scenarios demand high real‑time performance, requiring substantial bandwidth networks to ensure rapid data transmission and sharing, thereby maintaining transmission stability.
(2) Full‑Scenario Coverage and Precise Sensing
Large‑scale edge vehicle‑road coordination applications focus on optimizing roadside traffic facilities.
High‑density, high‑precision front‑end sensing hardware and software are needed to achieve intelligent coverage across all scenarios, including road sections, tunnels, and bridges.
The sensing system must maintain stable performance under low‑visibility conditions such as rain, fog, and nighttime, promptly detecting and responding to anomalies.
To achieve near‑all‑weather operation, the precision sensing capability of the system is critical.
(3) Centralized Management of Multiple Devices in Harsh Outdoor Environments
Complex geological conditions along highways, long transmission distances, diverse field environments, and susceptibility to thunderstorms, dust, high temperatures, and humidity pose significant challenges.
There is an urgent need for centralized management of multiple devices to ensure stable operation and effective maintenance.
Shanghai MRDCom Co., Ltd.'s MRD industrial switches, featuring deterministic transmission, low latency, and high reliability, have been widely deployed in roadside infrastructure for vehicle‑road coordination, data center expansion, and other applications. The TSN time‑sensitive networking switches enable millisecond‑level switchover in the event of link or switch failures, ensuring reliable, efficient, sustainable, and stable transmission of video data. This guarantees rapid system recovery in case of faults, thereby safeguarding traffic smoothness and safety.
