Germany is collecting over 3 billion data points annually related to traffic, a surge enabled by new legislation and a growing investment in digital infrastructure, according to recent reports. The increased data collection is intended to improve urban mobility and reduce emissions, but the full impact remains to be seen.
The new Mobilitätsdatengesetz (Mobility Data Act) is a key driver of this shift, marking a turning point for intelligent transport systems. The law facilitates the collection and analysis of traffic data, aiming to create more sustainable and efficient mobility solutions. Federal Minister Dr. Volker Wissing has positioned digital networking as essential for a modern transport infrastructure, emphasizing the use of real-time information to optimize traffic flow.
Cities across Germany are increasingly investing in digital platforms to capture environmental and traffic data. These multimodale digitale Mobilitätsplattformen (MDM) – or multimodal digital mobility platforms – are central to the Mobility-as-a-Service (MaaS) concept, bundling various transport options to simplify multimodal travel. The Umweltbundesamt (Federal Environment Agency) has been analyzing the competitive landscape of these platforms and identifying factors influencing their adoption.
The availability of high-quality traffic data opens up a range of possibilities, from strategic infrastructure planning to real-time traffic management and innovative user applications. Sensor networks and digital platforms are gathering information in real-time, contributing to improved traffic flow and reduced emissions. The Bundesministerium für Umwelt, Naturschutz, nukleare Sicherheit und Verbraucherschutz (BMU) – the Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection – is researching the environmental and climate impacts of digital solutions in mobility.
While the potential benefits are significant, the BMU acknowledges that digitalization alone does not guarantee greater sustainability in transport. The ministry is developing regulations to strengthen the ecological potential of digitalization in the transport sector and minimize risks. A planned revision of the Personenbeförderungsgesetz (PBefG) – the Passenger Transport Act – aims to integrate ridesharing and ridepooling as supplements to public transport, extending these services beyond test environments.
The national platform “Mobilithek” is being established as a central hub for data collection. This initiative aims to improve efficiency in public transport and promote sustainable mobility concepts. However, the BMU is as well studying how networked infrastructure and vehicles will affect road capacity, seeking to develop data-driven policies.
The focus on data collection extends beyond simply measuring traffic. The goal is to create a holistic understanding of urban mobility systems, enabling more precise analysis, reduced congestion, and improved transport options for users. The integration of real-time data allows for dynamic traffic steering and the development of new mobility services.
Despite the progress, questions remain about how the collected data will be used and whether it will truly lead to more sustainable outcomes. The BMU has not yet released its findings on the environmental impacts of digital mobility solutions, and the revision of the PBefG is still under consideration.
