Sierzega at Kommunalmesse Klagenfurt 2025

Published by Sierzega – October 7, 2025

From October 2–3, 2025, we presented the latest advancements of our speed displays and traffic counters at the Kommunalmesse in Klagenfurt and, for the first time, introduced our new platform SAI – the central solution for managing and analyzing all Sierzega traffic data.

At our booth, we showcased a live demo of the new SAI platform and demonstrated how the GR36, GR48 and SR7 devices integrate seamlessly into smart city environments. The platform provides a clear overview for managing, comparing and analyzing all recorded traffic data. Initial AI-assisted evaluations further support the detection of traffic trends and irregularities.

We sincerely thank all visitors for the numerous visits, the interesting discussions and the great interest in our traffic safety solutions.

Sierzega Display Featured on BILD.de

Published by Sierzega – 20 September 2025

A recent piece on BILD.de (article in German) features one of our speed displays as the cover image — a clear signal that traffic safety and point accumulation are high on the agenda.

The article examines which German cities see the most points in the driver fitness registry. These regional disparities make clear the demand for effective traffic monitoring — and that’s exactly where our LED displays and intelligent messaging systems come into play to raise awareness and increase road safety.

GATS Project: Speed Displays for Enhanced Safety in Cologne

Published by Sierzega – 18 August 2025

As part of the GATS project (GeschwindigkeitsAnzeigeTafeln - Speed Display Signs), the city of Cologne, in cooperation with Verkehrswacht Köln e.V., has installed ten of our innovative GR36CL speed displays. Our displays measure vehicle speed using radar and display this information with LED indicators, smileys, and personalized messages to guide drivers toward safe speeds – without imposing penalties.

Our goal as a manufacturer is to increase traffic safety, particularly at sensitive locations such as school routes, as well as to collect valuable traffic data for analyzing driver behavior. The displays are mounted by traffic cadets on lampposts and remain at each location for four weeks to avoid habituation. Citizens can submit location suggestions directly to Verkehrswacht Köln.

The first installation took place in front of an elementary school on Neusser Straße, where the display emphasizes the 30 km/h limit and secures the school route.

As in every city, traffic safety is a hot topic in the 20.000 inhabitants city of Haiger. After quickly discarding the idea of using radar traps, the city administration decided in favour of 16 GR33CL Speed Displays.

At a service visit a few weeks after the installtion, Mr. Thielmann, road traffic specialist, praised the „uncomplicated and professional handling before and after the order“. „Since the installation, the speed level within the city area has measurably declined - sample measurements prove that. Additionally, there was not a single civic complaint about speeding.“, Mr. Thielmann said.
