Case Study: Variable-message Sign Installed at Baishan Interchange, Shenyang

At Baishan Interchange in Shenyang, a new variable-message sign (VMS) has been successfully installed to improve real-time traffic communication and road safety. The project uses a P16 LED display measuring 3.072mx4.096m(approximately 200 inches), designed for high visibility, durability, and smooth information delivery under all weather conditions.

Enhancing Traffic Efficiency

The variable-message sign plays a key role in guiding drivers through busy interchanges. By displaying real-time traffic updates, lane information, and weather warnings, it helps reduce congestion and prevent accidents. As an electronic traffic sign, it connects to the city’s intelligent transportation system, allowing remote updates and dynamic control. Traffic managers can instantly modify displayed content to inform drivers about detours, emergencies, or speed limits.

Clear and Reliable Visuals

This digital road sign adopts high-brightness LEDs and an adaptive light sensor system. Even in direct sunlight or at night, the screen maintains excellent visibility. The matrix sign structure ensures uniform color and smooth display transitions. The P16 pixel pitch provides clear, readable text and graphics from long distances, making it ideal for expressway interchanges and complex urban roads.

Intelligent and Energy-efficient Design

The dynamic-message sign features a smart control system for automatic brightness adjustment and energy saving. It supports multiple communication protocols, enabling integration with other smart city devices. The modular design allows easy maintenance and quick replacement of LED modules. Compared with traditional message boards, this system consumes less power and offers a longer service life.

Reliable Operation and Advanced Monitoring

This electronic-message sign also includes a remote monitoring platform that tracks screen performance in real time. Technicians can detect faults, adjust brightness, or upload new content through a centralized system. In harsh weather conditions such as heavy rain or snow, the waterproof and dustproof cabinet maintains stable operation. Its efficient heat dissipation design prevents overheating, ensuring consistent display quality and reliability throughout the year.

Safer, Smarter Roads

By deploying this led message sign at Baishan Interchange, Shenyang has taken another step toward building a smarter transportation network. The led Traffic signage enhances road management efficiency and provides drivers with instant, reliable guidance. As cities continue to upgrade their infrastructure, variable-message sign will remain vital tools for promoting safe, efficient, and intelligent traffic operations.
