Solar railroad crossing protection B-20

Solar Railroad Crossing Protection – Active B-20 STOP Sign with Radar

Solar active B-20 STOP sign is a modern solution for securing railroad crossings and dangerous intersections. Equipped with a radar sensor, the sign activates pulsing LED lights only when an approaching vehicle is moving at excessive speed or shows no intention to stop. This approach eliminates driver habituation to constantly flashing signs and significantly improves warning effectiveness.

Why Use an Active B-20 Sign?

These systems are particularly recommended in high-risk collision areas, where enhanced visibility can save lives:

Railroad crossings and siding stations
Dangerous intersections
Roads with limited visibility
School zones and pedestrian crossings
Access roads to industrial plants and warehouses

LED Technology and Solar Power

The sign uses energy-efficient LED technology with very low power consumption, allowing fully autonomous operation without electrical connection. Intelligent brightness control automatically adjusts LED intensity according to ambient light conditions—ensuring high visibility during the day and preventing driver glare at night. This feature also extends operation time under limited sunlight conditions.

Key Features

Radar detecting vehicle speed and stopping intent
Warning activation only in case of danger – eliminates habituation effect
Solar power supply – complete installation autonomy
LED technology – low energy consumption, high visibility
Two versions available – yellow LEDs or red frame with white lettering
Durable construction – lightweight and robust composite material
Reflective film coating – II or III generation
Automatic brightness adjustment – optimal visibility 24/7

The active B-20 STOP sign is one of the most effective solutions for securing railroad crossings and critical road points, providing fast and clear warnings to drivers. It is a proven technology that significantly enhances road safety.

Active B-20 STOP sign 800 mm is an advanced solution for securing railroad crossings and critical road areas. Powered by solar energy and equipped with a vehicle speed radar, the sign activates pulsing LED lights only when it detects an approaching vehicle that shows no intention to stop or is traveling at excessive speed.

This system eliminates driver habituation to constantly flashing signs and ensures a prompt warning response only in genuine hazard situations. It significantly increases the effectiveness of warnings and improves safety at railroad crossings and intersections.

Key Features and Functions

Sign diameter: 800 mm – fully compliant with regulations
Solar power supply – minimum 120 hours of operation without sunlight
Doppler radar – measures vehicle speed and assesses stopping intent
Bidirectional detection – the sign also reacts to departing vehicles
No habituation effect – activation only occurs in real hazard situations
Energy-efficient LED lighting – high visibility, low power consumption
Ideal for remote locations – no electrical connection required
Durable construction – designed for variable weather conditions

Recommended Applications

Railroad crossings
Dangerous intersections
Roads with limited visibility
Areas with high vehicle traffic
Locations without access to the electrical grid

Active solar-radar B-20 STOP sign 800 mm is one of the most effective warning solutions for locations where road safety is critical. With autonomous power and intelligent operation mode, it provides long-lasting, reliable, and highly effective hazard signaling.
