No EU-type-approved automated bus exists — the single biggest blocker to scaled deployment in European cities

Headline Finding

As of April 2026, no EU-type-approved automated bus exists — every automated bus operating in Germany and Austria still requires a safety driver on board, and all pilots remain in test mode. A two-day expert workshop convened by EIT Urban Mobility and AustriaTech, drawing participants from cities including Bochum, Hannover, Munich and Graz, reached a clear consensus: the technology is moving, but the surrounding ecosystem — governance, funding, procurement, and type approval — has not yet caught up. This is the canonical pacing-problem finding for European automated public transport: the deployment clock is running, but the governance clock is stalled at the type-approval gate.

Detail

The workshop, held on 30 April 2026, brought together city authorities, public transport operators, research institutions and experts from Austria and Germany. Participants included Bogestra (Public Transport Operator Bochum), the cities of Bochum, Hannover and Munich, DEKRA, DLR, Graz Holding (Public Transport Operator Graz), Region Vorarlberg, SteuernLenkenBauen (Project Management Hannover), with Munich, Graz and Turin presenting current agendas and POLIS and the European Commission providing a European perspective.

The central finding on type approval: no EU-type-approved automated bus currently exists, and this is identified as the single biggest blocker to scaled deployment. Every automated bus operating in Germany and Austria today does so with a safety driver on board. Pilots are underway in several cities across the DACH region but remain mostly in test mode. A vehicle capable of carrying full passenger loads on a fixed line without human supervision has not yet received EU type approval under an Automated Driving System (ADS) framework.

The commercial market compounds the problem: most available automated vehicles are small shuttles designed for low passenger volumes, while cities require full-size buses and long-term certainty on governance and funding. Manufacturers such as MAN are beginning to move toward full-size automated buses, but automotive production lines become viable only at very high volumes, and the bus market — already smaller than the car market — risks further fragmentation from the rise of on-demand services.

Liability is unresolved: the boundary between operator liability and manufacturer liability remains poorly defined, casting a shadow over investment decisions on both sides. AI-based ADS compounds this because AI systems are inherently difficult to audit through traditional testing protocols — regulators face a conceptual challenge in certifying a system whose decision-making cannot be fully traced. Technical Inspection and Certi fication (TIC) organisations such as TÜV and DEKRA are identified as indispensable bridges between regulatory intent and technical reality. A promising approach — measuring outcomes rather than inspecting the algorithmic black box — is gaining traction but has not yet been formalised in EU type-approval frameworks.

Data sovereignty is a cross-cutting concern: automated driving technology developed outside Europe and dependent on non-European data infrastructure raises questions about resilience and control. Several participants argued that a genuinely European approach — not merely to regulation but to the technology stack itself — should be an explicit policy objective if public transport authorities are to retain meaningful control over the systems they operate.

At national level in Germany, test permits are issued by the Kraftfahrt-Bundesamt (KBA) on a case-by-case basis, resulting in slow processes, and responsibility for ongoing technical supervision of automated fleets remains unresolved. Cities should plan for approximately one year of lead time for each ADS operating permit application. At EU level, implementing regulation 2022/1426 provides a useful basis, but the absence of a fully harmonised type-approval framework — one that bridges UNECE regulations, EU requirements and national conditions — means a vehicle approved in one member state cannot automatically operate in another.

Governance Implication

1. The type-approval gap is the primary governance bottleneck: the technology clock has moved to the point where driverless operation is technically feasible, but the governance clock is stalled because no EU-harmonised ADS certification framework exists for full-size buses — destroying fiscal value by blocking the investment decisions of both operators and manufacturers.
2. Unresolved operator-vs-manufacturer liability is a legitimacy lever failure: without a settled liability framework (either through regulation or case law), elected decision-makers remain reluctant to champion ADS projects, and public trust cannot be built — directly implicating the legitimacy lever and chapter 6 (rules and instruments).
3. The AI auditability problem requires a new certification paradigm: because AI-based ADS cannot be fully traced through traditional testing, the outcome-measurement approach (rather than algorithmic inspection) needs formalisation in EU type-approval frameworks — a task for TIC bodies such as TÜV and DEKRA that neither manufacturers nor public authorities can perform alone.
4. Data sovereignty is a latent fiscal and legitimacy risk: dependence on non-European ADS technology stacks and data infrastructure creates supply-chain and control vulnerabilities that, if unaddressed, will constrain public transport authorities’ ability to govern the services they are responsible for — a fiscal and legitimacy lever concern.
5. The KBA case-by-case permitting regime and the one-year city-level lead time for ADS operating permits are quantifiable governance-clock lags that cities and national authorities must factor into deployment timelines now, before the technology clock advances further.
