Schlothauer & Wauer

What Schlothauer & Wauer does

Schlothauer & Wauer Ingenieurgesellschaft für Straßenverkehr mbH is a German engineering and software firm founded in 1991 and headquartered in Berlin, specializing in the planning, evaluation, and optimization of traffic signal systems (Lichtsignalanlagen). The company serves municipalities, state and federal authorities, public transport operators, and traffic engineering consultancies in Germany and internationally, with 675+ software customers and 800+ completed traffic and mobility projects across more than 20 countries.

The company's core technology is LISA, a modular desktop software platform developed over roughly 35 years that supports fixed-time control (LISA S), traffic-actuated and rule-based control (LISA M and LISA XL), model-based adaptive control (ImFlow), and network-level coordination (INES). Recent releases (LISA 8.2 in March 2025 and LISA 8.2.1 in August 2025) add C-ITS and CCAM capabilities for vehicle-to-infrastructure communication, GLOSA services, and CAM/SREM message handling, with export compatibility to OCIT-I/OCIT-C standards and integration with PTV Vissim and SUMO simulation environments.

Revenue is generated through three streams: software licenses bundled with annual maintenance contracts (recurring subscription revenue), paid engineering and consulting services for traffic planning and data collection, and a tiered training program (€250–€1,250 per participant with discounts for maintenance customers). Go-to-market is sales-led, with direct enterprise engagement, a customer portal for software delivery, and a research footprint via federal projects with BASt and BMVI. The company is privately held and operates as part of the SWARCO Group, with reported annual revenue of €9.1 million and a workforce of 100+ employees across five core German offices (Berlin, Dresden, Munich, Tübingen, Wiesbaden).

Core offering

Schlothauer & Wauer develops and sells the LISA software platform for planning, evaluation, and optimization of traffic signal systems (Lichtsignalanlagen), supporting fixed-time, traffic-actuated, rule-based, and model-based control, as well as C-ITS/CCAM functions. The company complements the software with traffic engineering consulting, mobility planning, traffic data collection, and training services for public sector clients in Germany and internationally.

Product overview

Schlothauer & Wauer's product portfolio centers on LISA, a comprehensive modular software platform for traffic signal planning, evaluation, and optimization. The architecture consists of the core LISA platform with tiered modules: LISA S for fixed-time control, LISA M for coordination optimization, and LISA XL for rule-based traffic-actuated control. Additional modules include ImFlow for model-based control, INES for network control, and a C-ITS Paket for cooperative intelligent transport systems. The software supports export to standards like OCIT-I/OCIT-C and integrates with simulation programs including PTV Vissim and SUMO.

Direct peers

• Rhythm Engineering (InSync): US-based provider of the InSync adaptive traffic signal control system. Directly comparable as a specialist vendor of adaptive/model-based traffic signal control software targeting municipal customers; competes in the same model-based control category as S&W's ImFlow module.
• PTV Group: German-based provider of PTV Vissim traffic simulation software and transport planning tools. Directly comparable as a specialist traffic engineering software vendor serving the same municipal and consultant customer base; LISA explicitly exports signal plans to PTV Vissim and SUMO, making them both complementors and adjacent competitors.

Regional players

• TRL Software: UK-based spin-off of the Transport Research Laboratory offering traffic engineering, signal design, and UTC software (including OSCAR and UTC systems). Comparable as a specialist traffic engineering software vendor serving the UK and Commonwealth public sector, but operating in a different geographic market than S&W.

Broad incumbents

• Kapsch TrafficCom: Austrian-headquartered global provider of intelligent transportation systems including traffic management, tolling, and connected vehicle solutions. Comparable as an end-to-end ITS vendor serving the same public-sector customer base with adaptive signal control and TMC software, but operating at significantly larger scale and global reach.
• Q-Free ASA: Norwegian-headquartered ITS vendor offering traffic management, tolling, and C-ITS solutions globally. Comparable as a broad incumbent in adaptive signal control and traffic management centers serving the same European public-sector customer base as S&W.
• Yunex Traffic: Former Siemens ITS division and a global market leader in urban and interurban traffic management hardware, software, and services. Comparable as it offers overlapping adaptive signal control and traffic management center solutions to municipalities, but as part of a much broader portfolio that includes hardware, sensors, and connected vehicle infrastructure.
• Iteris: US-based provider of smart mobility infrastructure management, including intersection analytics and ClearMobility platform. Comparable as a vendor serving municipal DOTs and traffic engineering professionals with planning and analytics software, though at much larger scale and with US-centric focus.
• Cubic Transportation Systems: Major US-based transportation technology vendor offering traffic management, signal control (Trafficware), and payment systems to public agencies. Comparable as a broad incumbent in traffic signal control and traffic management centers, with direct competition in the model-based/adaptive control segment.
• SWARCO Group: The parent company of Schlothauer & Wauer, SWARCO is a global leader in traffic signaling systems, V2X, and retroreflective road markings. Comparable as a traffic management and signaling systems incumbent; S&W's LISA software is approved for SWARCO's ACTROS control units, illustrating the integration.

Emerging players

• Miovision: Canadian provider of AI-based traffic data collection and signal optimization tools, including the SmartSignal adaptive platform. Comparable as an emerging technology-driven vendor targeting municipal traffic engineers with cloud-native and data-driven alternatives to traditional desktop planning tools.
