Carmen® Dangerous Goods Signs

Dangerous goods – identified safely


Traffic management brings the most benefits when all vehicles are properly identified – especially if a vehicle carries dangerous goods. Such function is just a small add-on to an ITS system, but can save lives in risky situations.

The Carmen® Dangerous Goods Signs software is for recognizing and deciphering the hazard identification number (shortly HIN number or also Kemler code) of commercial vehicles carrying hazardous materials. By reading these codes, traffic monitoring and road safety systems can become highly automated – roads, tunnels and bridges remain safe while transporting dangerous cargo.

hazardous material identification

When information matters

A truck is in flames, a liquid is leaking out of its tank and who knows if it is going to explode in the next second or not… In such events, it is a must to be aware whether that vehicle carried any dangerous goods or not. Modern transportation systems track all these information using automatic recognition of hazardous material signs – an identifier such trucks are obligated to possess. This is one of the moments when having that information is crucial.

Highlighted features


No.1 accuracy

Carmen®, the industry-praised recognition algorithm provides peak accuracy in any traffic system.


Complete API package

This software is designed for your integration: connect it with any 3rd party system using the extensive API.


Works on Windows and Linux

We do not limit your development environment, both Windows and Linux-based systems are supported.


Built-in motion detection

You can either use the built-in motion detection for triggering or connect an external trigger system.


Wide development coverage

Versatile APIs are included for the common programming languages, such as C/C++, C#, .NET, Java.


Connect seamlessly to your ANPR

Carmen® ADR works with the same API as Carmen ANPR. It takes a minute to add this new function.



ADR signs

These signs consist of two parts, the top number (2 digits) is the UN number for identifying the hazardous material while the bottom number (4 digits) is a general hazard identifier encoding the hazard class and subdivision.


E-ADR signs

The empty version of ADR signs is also identified by Carmen® ADR. This sign is used on the front and back of such vehicles that carry multiple hazardous materials.
