Flexible management of tunnels and freeways increases road safety
Modern traffic management systems ensure more harmony on the roads. This reduces congestion, accidents, travel time and emissions, while at the same time significantly increasing the capacity of roads and tunnels.
More safety with modular tunnel and freeway management
Our modern traffic management system contributes to greater safety in tunnels and on freeways with situation-specific warnings and speed limits - and protects people, structures and the environment.
Sitraffic Varia supports efficient and demand-based traffic management
Sitraffic Varia can be used for interurban and urban freeways and highways as well as for tunnels and enables comprehensive tunnel and highway management.
Sitraffic Varia
- Monitors and controls lighting, ventilation, power supply, fire detection and pumps in the tunnel
- controls variable direction signs and traffic signs as well as permanent light signs and barriers
- delivers data to the traffic information services
- can integrate toll systems, video systems, emergency call systems and systems for environmental and traffic data collection
- works easily and smoothly with traffic centers and outstations of various kinds


Sitraffic Varia combines a solid technology base with expert knowledge and project experience
Sitraffic Varia incorporates all the expertise of our traffic experts - starting with design and development, through testing and commissioning, to the integration into your traffic management concept. Sitraffic Varia is structured in a way that for standard control system functions a middleware is used which already provides many basic functions (e.g. hot standby, user interface, multilingualism, user administration, archiving, reports, etc.). As a result, Sitraffic Varia helps to make space for the development and implementation of project-specific functions (e.g. ventilation, lighting, traffic control, etc.) - for traffic management that is perfectly tailored to your requirements.
Scalable and modular
With Sitraffic Varia you can implement the traffic management system that suits your needs: from a compact freeway control center to a tunnel control center with various operating facilities to a fully developed, higher-level Varia Nova control center. The system can be used at all control levels and grows with your requirements – including the connection to systems for long-distance traffic, urban traffic and parking.


Highest safety standards
Safety is a top priority at Sitraffic Varia. The system meets the requirements for functional safety (IEC 61508). The security processes are ISO/IEC 27001 certified and in the area of IT security the system ensures appropriate security levels according to IEC 62443 (Industrial communication networks - IT security for networks and systems). As a result, Sitraffic Varia not only improves the safety of road users in tunnels and on freeways, but also protects buildings from damage and operators and society from costs and risks.
Tunnel projects go digital: Building Information Modeling and Digital Twin
Yunex Traffic uses state-of-the-art methods in tunnel projects. With the help of a Building Information Management (BIM) model, a virtual tunnel including all components is first created together with the project partners involved. Only when this model meets all requirements and specifications is the real tunnel implemented. The model can then be developed into a digital twin of the tunnel and used throughout the entire life cycle of the tunnel. Your advantages:
- Higher project quality
- Faster implementation
- Reduced project costs
- Optimized operation
Tunnel and Freeway Management
No matter if individual components or complete turnkey solutions, Yunex Traffic offers highly flexible solutions that can be perfectly adapted to your requirements.
