The global-oriented highway digital information interaction system has achieved multidimensional breakthroughs through the integration of technologies:
I. Core Technology: Three Supporting Pillars
Digital Transmission and Networking: Implement an all-optical four-level architecture of "National - Provincial - Road Section - Roadside". Stepless transmission from 2M to 100G is supported by OTN equipment, and "integrated bearing network" is built by IP + optical fusion to support the parallel operation of multiple services such as toll collection and monitoring. Microwave is used for blind-area compensation in extreme scenarios, thus enabling rapid networking within 15 kilometers and ensuring uninterrupted data transmission.
Digital Signal Processing: Use MEC nodes for 10-millisecond-level real-time processing; employ video AI for the recognition of abnormal signals like landslides and falling rocks; iFit/DQODN technology allows for meter-level fault location, thereby enhancing troubleshooting efficiency.
Communication Protocols: The dual modes C-V2X and DSRC are integrated, and the traffic light and vehicle parameter data are sent according to the international SAE J2735 standard. By using national cryptography SM9 encryption and TSN synchronization protocol, it achieves a delay of ≤10 milliseconds and a packet loss rate of <0.1%, thus complying with the requirements of global safety and stability.
II. Core Application Scenarios
Traffic Flow Management and Control: The high-definition roadside data are sent back through the ONU ring network and uploaded to the cloud via the OTN link. Traffic signals are dynamically changed according to SPAT information. After implementation in Beijing Yizhuang, the traffic capacity was increased by 17.9%, and the architecture is suitable for global road conditions.
Intelligent Equipment Operation and Maintenance: The equipment status signals are sent via hard pipe isolation. Intelligent diagnosis makes it possible to locate the optical fiber fault at the meter level. The Xi'an project, through the use of this technology, achieved a 90% reduction in maintenance time, and the model can be duplicated abroad.
Vehicle-Road Collaboration Safety: Within 100 milliseconds, RSUs and OBUs through the PC5 interface complete blind spot warning and traffic light status push. The low latency on F5G network is ensured by Guizhou Expressway, and the parameters are in line with the international trends.
Environmental Early Warning and Protection: The meteorological data from the mountain road segments are sent to the cloud via SD-WAN. The early warning system for landslide and snowfall is set off by AI processing, and the information is pushed in different languages, thereby catering to the complex overseas environment.
III. System Advantages: Global Value Reflection
High Speed
An 800G single-wavelength bandwidth supports the concurrency of high-definition videos and a massive amount of sensor data, while 23Mbps is sufficient for vehicle-road collaboration's high-frequency update, thus making it viable for heavily trafficked scenarios.
Stability
Zero interruption is realized through ASON multi-path protection and ring networks. The microwave blind area compensation for signal breakpoints during the reconstruction and expansion solves the problem and, thus, is suitable for overseas construction and operation and maintenance.
Security
The prevention of crosstalk is ensured by hard pipe isolation; the use of national cryptography algorithms and compliance with Cybersecurity Class Protection 2.0 together provide the security of core data, thus, taking away the concerns that come with overseas.
Interconnectivity
IPv6 + slicing are the two factors that break down system barriers and make end-to-end connectivity possible. The "integrated dispatching" model of Xi'an's emergency platform is instrumental in the building of efficient transportation systems abroad.
