This year, the Inframatic company was again present at the NAT conference 2024 in Nashville, Tennessee and informed each other about the latest developments in tunnel technology. Our Stefan Haydn was there as always and was able to have many good discussions with all the companies involved and those responsible for the tunnel industry and the authorities.
Have you ever wondered why you keep standing at red lights at intersections for so long and no one comes from the other side? The answer is very simple: these intersections are controlled by simple timers that have no idea whether a vehicle is there or not. And our solution to this problem is even simpler. Rely on our traffic management server.

If you think that sounds complicated and expensive, you’re wrong. Where the relays and timers are now mounted, we simply replaced the old control components with a single control unit that processes and switches everything. To detect wheter a car or bicycle stands in front of the intersection we use cameras and detect the objects. Of course separeted by the different lanes. Depending on the local weather or environmental influences, we supplement the cameras with radar or lidar detection devices.
Control unit with digital outputs and image processing integrated
In addition to the advantage that no one has to wait unnecessarily in front of an intersection, our solution also offers many other advantages free of charge:
Cam images can be used also for law enforcement
Recording of the images
Cascading of following intersection is possible – Green light section over multiple controllers
Interface to other devices or control systems is available (e.g. BacNet, TCP, etc.)
Multiple fallback levels are integrated (in the event of failure of individual or all sensors)
Inframatic is proud to have attended this year’s NAT conference. Our colleague Stefan Haydn presented the topic of flow control in tunnels as a co-speaker.
What is a tunnel with a safety ventilation without a serious test of the same? Nothing to be exact. Inframatic changes that by testing the safety-relevant aggregates. Fire ventilation, using ultrasonic measuring devices in a cross arrangement, to test whether the air speed achieves sufficient performance even in the event of an incident. At the same time, we tested airflow visually, using smoke grenades. These show “mercilessly” where any defects are. In the case of the extension of the San Francisco Metro from Union Square to China Town, no doubt about it. The following tests were carried out:
San Francisco metro station “Union square”
Ultrasonic cross-measurements of the airspeed across the whole tunnel section, 4 pcs. at the same time
Smoke grenade test to make visible where the airflow goes
Door force measurements to comply with regulations
Noise measurements
Anemometer measurements

It’s possible. Not tomorrow,

We plan and build complete solutions for extensive electric charging stations and infrastructures in the field of electric mobility. We rely on the most modern technologies. Above all, the high-performance charging technology (HPC, high power charging). This enables direct current charges of up to 500 kilowatts. This means that an electric vehicle is 90% charged within 5-10 minutes (depending on the vehicle type and approved charging capacity).
Our services:
Overall planning of the charging infrastructure
Energy and power calculations
Network planning and execution for remote monitoring
Hardware planning of the charging stations
Software development of the charging controller
Software development of the control system technology
Software and hardware for EFT / POS
Commissioning of the plants
The future is electric
The “Global EV Outlook 2022” of the International Energy Agency IEA recently provided information on the increasing market presence of electrically powered vehicles. According to the report, 6.6 million plug-in vehicles were newly registered (battery-only or plug-in hybrids with a battery and an internal combustion engine). That is more than twice as many as in 2020. At the end of 2021, there were over 16 million electric vehicles on the roads worldwide. And the future is also clearly electric. The European Union has already issued a ban on petrol-powered vehicles and the United States is also pushing ahead with charging stations and EV’s in large steps.
