Traffic light renovation on Trothaer Straße: construction work starts now!

Yesterday, on June 27, 2025, the modernization of the traffic lights at the intersection of Trothaer Straße and Seebener Straße began in Cologne. The work, which is expected to last until July 11, 2025, includes the renewal of the central control unit and the entire outdoor traffic light system. During the construction phase, the traffic lights will be completely decommissioned, which also means that road users will be reminded of the need for increased attention to safety and consideration.

To ensure smooth traffic flow during the construction period, one lane will be closed from each direction. A speed limit of 30 km/h applies throughout the intersection, which represents another safety factor. It is important to take the special circumstances into account, as many road users have to adapt to the situation.

Strengthening road safety

A key element of this modernization is the installation of a red light speed camera for traffic traveling into the city. This is intended to document red light violations and instead ensure stricter punishment for traffic violations. The fines are not without their consequences: Anyone who runs a red light will have to pay 118.50 euros and one point. For a crossing that takes longer than a second, it is already 228.50 euros and two points. If a driver endangers other road users, the fine can rise to 348.50 euros.

These measures are intended not only to increase safety at intersections, but also to consistently punish reckless behavior in traffic. After all, road traffic is a complex interaction in which any change to a traffic signal system, such as entering a construction site, can have far-reaching effects on the flow of traffic. The approximately 1.5 million traffic lights nationwide are tasked with reducing accidents and ensuring a steady flow of traffic, according to information from Catalog of fines.

A look at the technology

Engineers like Wilke Reints from Siemens are working on the optimal functioning of traffic lights and are taking on the challenge of efficiently controlling traffic in cities. Traffic lights are much more than just simple light signals; They are complexly interconnected and require coordinated control in order to function optimally during peak times such as mornings and evenings. Loud Geo Even a small adjustment to a single traffic light can have far-reaching effects on the entire traffic flow.

The technical equipment is supported by powerful traffic computers that operate in the so-called control centers to optimize traffic in real time. These modern approaches are crucial in order to be able to respond to the increasing demands in urban transport. An example of this is the first electric traffic light, which was installed in Hamburg in 1922.

With the renewal of the traffic lights on Trothaer Straße / Seebener Straße, Cologne will take a further step into the future of traffic safety. Residents and road users are asked to be particularly careful during construction.
