Intelligent Traffic Systems applications—traffic controllers, edge AI nodes, sensing cabinets—require hardware that is scalable, field-serviceable, and stable under harsh outdoor conditions.
Subrack architecture addresses these needs with standardized modules, high-speed backplanes, and industrial-grade mechanical design, becoming the preferred hardware platform for smart intersections around the world.
Intelligent Traffic Systems often face four critical engineering challenges:
● Mixed hardware, poor scalability
AI cards, communication boards, I/O modules, relays, and power units are typically built by different vendors and lack a unified structure—making upgrades and expansion difficult.
● Tight maintenance windows
Traffic controllers cannot shut down during peak hours. A 3–5 minute downtime may cause significant congestion.
● High wiring and installation cost
Each city or department uses slightly different configurations, resulting in repeated customization, on-site wiring, and long delivery cycles.
● Harsh outdoor environment
Equipment must withstand vibration, dust, humidity, heat cycles, and heavy rainfall.
Subracks are designed exactly for these pain points—turning a complex field system into standardized, serviceable hardware.
• AI inference cards, video encoding modules, 5G communication boards, power modules, and relay boards all slide into a unified subrack frame.
• “One board = One function” makes expansion or upgrade a simple plug-in / pull-out operation.
• No need to replace the whole system.
• Power, Ethernet, CAN bus, GPIO, and high-speed signals are routed through the backplane.
• Zero loose wires, reducing assembly and wiring labor by up to 60%.
• Eliminates wiring errors commonly seen in terminal-block installations.
● Fast field recovery (<5 minutes)
Technicians can replace faulty boards without shutting down the system.
The subrack automatically identifies the new module and restores operation—critical for traffic controllers and edge computing nodes.
● Front-panel status indicators
Power / Run / Fault LEDs combined with backplane telemetry (voltage, current, temperature) enable remote diagnosis.
● Higher first-time repair accuracy (>95%)
Maintenance teams know exactly which board is failing before arriving on site.
● Unified 3U/4HP or 6U/8HP boards
Manufacturers can complete aging tests and pre-assembly at the factory.
On-site installation becomes “slot-based,” eliminating manual wiring.
● Cross-department compatibility
Traffic control, city management, police, and environmental monitoring can share the same subrack platform—changing only the functional board.
● Spare-parts reduction by 70%
Standardization drastically cuts storage and maintenance costs.
• Metal profile frame with EMC shielding
• Compliant with:
• IEC 61587 vibration resistance
• IK08 impact protection
• IP55 dust & water protection
• Suitable for deployment in roadside cabinets, junction boxes, and open-air sites.
• Dual 48V DC inputs
• 100ms power interruption ride-through
• Locking ejector handles keep heavy boards secure even under strong vibration
• MTBF ≥ 100,000 hours, meeting GB/T 20609-2023 Traffic Controller Reliability standards.
Each intersection uses an embedded subrack computer integrating detection, communication, and scheduling boards.
All boards communicate via the backplane, enabling intersection-to-intersection coordination for fully distributed green-wave control.
Relay logic, diagnostics, communication, and power modules are consolidated into a single subrack, reducing cabinet volume by 40% and cutting diagnostic time from hours to minutes.
This architecture is now widely used in smart poles, traffic controllers, and environmental monitoring systems.

Subrack architecture transforms complex urban hardware into a clean, scalable, reliable system:
• Modular → faster integration

• Standardized → faster delivery
• Ruggedized → fewer failures
This is why subracks are rapidly becoming the default hardware framework for traffic controllers, edge AI systems, sensing nodes, and smart-city infrastructure worldwide.
1. How does a subrack improve the reliability of a Traffic Signal Controller?
A subrack provides standardized modules, hot-swap capability, and industrial-grade protection, ensuring the Traffic Signal Controller operates continuously even in harsh outdoor conditions.
2. Why are subracks widely used in an intelligent traffic system?
Subracks unify AI cards, communication modules, power units, and I/O boards into a scalable structure, making an intelligent traffic system easier to maintain, expand, and upgrade.
3. Can a subrack support ICS and Edge Computing Node applications?
Yes. The modular Eurocard architecture supports AI inference boards, high-speed networking, and redundant power, making it ideal for ICS platforms and any Edge Computing Node deployment.
4. What benefits do subracks bring to an Intelligent Environmental Monitoring Cabinet?
Subracks reduce wiring complexity, support backplane communication, and offer vibration-resistant design—perfect for an Intelligent Environmental Monitoring Cabinet that requires stable, long-term field operation.
5. Are subracks compatible with different communication buses used in intelligent traffic systems?
Yes. Subracks support Ethernet, CAN, GPIO, serial interfaces, and high-speed expansion options, allowing seamless integration across Traffic Signal Controller, ICS, and other intelligent traffic system equipment.
Subrack architecture delivers a clean, scalable, and field-serviceable foundation for every intelligent traffic system—from the Traffic Signal Controller to the ICS platform, Edge Computing Node, and Intelligent Environmental Monitoring Cabinet. By standardizing modules and improving long-term reliability, subracks help cities deploy smarter and more resilient infrastructure, making them an essential choice for modern ITS deployments. With these advantages, subrack-based solutions from Rdekono are powering the next generation of smart-city hardware.

The subrack does not have a series of profiles, and after receiving an order, it is usually customized and processed according to the drawings. Products from different customers and products of different specifications from the same customer all need to be redesigned and processed, resulting in higher costs;
