Crowd Communication at Carnival in NL & DE
Crowd Communication during Carnival

During Carnival 2025 in both ‘s-Hertogenbosch and Cologne, we focused on effectively managing visitor flows and ensuring safety through our Integrated Crowd Communication System and expertise in behavioral influence.
For direct communication with the public, we deployed our Integrated Crowd Communication System, consisting of mobile LED screens on a concrete base, known as HIKERS. These screens were controlled via a closed network from the safety center and provided real-time information to visitors. This allowed us to respond quickly to on-site situations and keep visitors informed with up-to-date and relevant information.
For the Municipality of ‘s-Hertogenbosch, the City of Cologne, and the Dutch Railways, we managed the entire process—from content production to delivering a fully integrated communication system. This enabled our clients to focus on other matters, knowing that all scenarios were prepared and pre-programmed.

The British Grand Prix is one of the largest sporting events in the UK. In 2025, Silverstone welcomed 500,000 people through its gates across the race weekend of 4-6 July — a figure the circuit published itself. The hardest moment of an event that size is not the arrival. It is the exit: a few hundred thousand people deciding to leave at roughly the same time, most of them heading for a shuttle bus.
In late June 2024, the AfD held its federal party conference at the Grugahalle in Essen. Tens of thousands of people travelled to the city that weekend to demonstrate, spread across dozens of registered protests — one of the largest public-safety operations in the city’s history. Keeping that many people informed and moving safely calls for clear, real-time crowd communication. That is why client Stadt Essen brought in CrowdCows.
