What GB infraSignal GmbH does

GB infraSignal GmbH is a 100% state-owned (landeseigenes) Berlin infrastructure management company and a wholly-owned subsidiary of Grün Berlin GmbH. It was established in January 2023 following the rekommunalisierung of Berlin's traffic signal management, which had been privately operated by Alliander Stadtlicht GmbH from 2006 to August 2022. The company is the exclusive contracting entity for the Senatsverwaltung für Mobilität, Verkehr, Klimaschutz und Umwelt (SenMVKU), responsible for the full lifecycle — planning, construction, modernization, operation, and maintenance — of more than 2,100 Lichtsignalanlagen (traffic signal installations) across Berlin, the largest such urban fleet in Europe. Its headcount is approximately 50, inherited predominantly from the predecessor operator, with CEO Katharina Marienhagen (previously head of Siemens Mobility's Traffic Engineering Region Nord) leading a functional team covering engineering, operations, IT, and modernization.

The company's product portfolio centers on physical traffic signal infrastructure and digitally-enabled control systems. Core services include Planung und Bau (planning and construction), Modernisierung und Umbau (modernization, including 1-Watt LED signal heads delivering up to 80% energy savings), and Wartung und Instandhaltung (maintenance). Technology-differentiating sub-products include C-ITS (Cooperative Intelligent Transport Systems) using Roadside Units for real-time vehicle-signal communication, adaptive signal control with video cameras and induction loops, ÖPNV-Bevorrechtigung (public transit priority for BVG buses and trams), and VeloFlow digital cycling displays supported by federal research funding. A citizen-facing Störungsmelder tool enables fault reporting by address, coordinates, or LSA-ID.

GB infraSignal operates under a single managed-services contract with the Land Berlin and is funded through public budget allocations; it has no external customers, no commercial pricing, and no equity financing. Approximately 100 signal installations are modernized per year, with a target of ~60 Roadside Units citywide by end-2025. Strategic co-development partnerships include BVG (bus priority pilots) and the Federal Ministry for Digital and Transport (BMVI-funded VeloFlow). Technology partners include SixData GmbH (lsaData fault-management software), Cloudflare Germany GmbH (website CDN), and Ape Unit GmbH (web implementation). The company is governed under political oversight of the SenMVKU and registered as GmbH (HRB 240221 B) at Mariendorfer Damm 1, 12099 Berlin.

Broad incumbents

• Kapsch TrafficCom: Austrian-based provider of intelligent transportation systems, including connected vehicle infrastructure, tolling, and traffic management. Comparable as a broad incumbent in the same V2X/C-ITS category where GB infraSignal is deploying RSUs, though Kapsch operates across many geographies versus GB infraSignal's Berlin-only mandate.
• SWARCO: Austrian-headquartered global leader in traffic signal systems, road marking, and urban traffic management solutions. Comparable as a technology provider whose signal heads and controllers may be deployed within GB infraSignal's fleet, and as a broad incumbent in the same ITS/traffic management category across European cities.
• Yunex Traffic: Former Siemens Intelligent Transportation Systems business, now owned by Atlantia, and one of the world's largest providers of traffic signal hardware, controllers, and urban traffic management software. Comparable as the underlying technology supplier that GB infraSignal deploys and operates; Yunex Traffic is the primary indirect peer through its technology-stack presence in Berlin's infrastructure.
• Siemens Mobility GmbH: Major rail and road mobility solutions provider, including traffic engineering services historically delivered by its Traffic Engineering division where CEO Marienhagen previously led Region Nord. Comparable as both a likely technology provider for Berlin's traffic infrastructure and a potential strategic partner for large-scale ITS modernization projects.

Others

• SixData GmbH: German software vendor of the lsaData traffic signal management system used by GB infraSignal for fault documentation and processing. Functions as a direct technology partner within infraSignal's operational stack rather than a competitor; relevant as a niche enabling vendor in the same German ITS software ecosystem.
• Alliander Stadtlicht GmbH: Predecessor service provider that managed Berlin's traffic signal infrastructure as general contractor from 2006 to August 2022. Relevant as the immediate predecessor organization whose employees and operational knowledge were transferred to GB infraSignal upon rekommunalisierung; remains in adjacent German energy and infrastructure markets.

Emerging players

• Iteris, Inc. US-based provider of smart mobility infrastructure management and intelligent transportation systems, including traffic signal coordination and adaptive control software. Comparable as a specialized ITS player focused on traffic management solutions for public agencies, though operating in North American municipal markets rather than German state-owned infrastructure.
• SIGNALBAU HUBER GmbH: German specialist manufacturer of traffic signal controllers and urban traffic management systems. Comparable as a domestic supplier of the underlying traffic signal technology that GB infraSignal operates; functions as an emerging niche player in the same hardware category.

Direct peers

• Stadtwerke München (SWM) / Münchner Verkehrs- und Tarifverbund: Munich's municipal utilities and traffic management operations, including traffic signal oversight for the Bavarian capital. Comparable as a German municipal-level operator with similar public-sector mandate over urban traffic infrastructure, though structurally organized differently than the dedicated GB infraSignal GmbH.
• Landesbetrieb Straßen, Brücken und Gewässer Hamburg: Hamburg's state-owned civil engineering and infrastructure agency managing traffic signals, bridges, and waterways. Functions as the most direct operating peer to GB infraSignal — a public-sector entity with end-to-end responsibility for traffic signal management in another major German metropolitan area under similar legal and political structures.
