For many cities, the past decade of mobility innovation has been defined by a wide range of pilot projects exploring digital platforms, multimodal services, and smart infrastructure. While many of these initiatives have demonstrated strong technical potential, the transition from isolated experimentation to fully integrated, system-wide deployment remains an ongoing challenge.
As cities now move from testing solutions to scaling them in real operational environments, questions of governance, interoperability, and long-term system alignment are becoming more critical than the technology itself. This was the central theme of the third webinar, “From Pilot to Scale: Deploying Integrated Mobility Systems”, where honoured speakers were invited to explore what it actually takes to move from experimentation to system-wide deployment.
Istanbul as a system bridging two continents
Unlike many cities still operating in pilot mode, Istanbul is already functioning as a high-complexity, high-demand mobility ecosystem. Its geography alone creates structural pressure. As ERTICO CEO, Joost Vantomme explained, “There is a central gravity in terms of linking the Asian side with the European side.”
This “central gravity” is not symbolic; it defines how mobility must function. Istanbul cannot afford fragmented systems. Integration is not a future ambition; it is a daily operational requirement.
Integration as lived reality, not design theory
In most cities, multimodality is still something users actively manage: separate tickets, disconnected systems, and complex transfers. In Istanbul, however, mobility is increasingly designed as a continuous chain rather than a set of isolated modes.
As CEO, Erdem Samut of iSBAK emphasised, “The impact of smart mobility is not just about technology; it is about improving the quality of life in a very tangible way.”
This reflects a key shift: integration is not about adding more modes. It is about ensuring that modes work together as a single operational system. Journeys across metro, ferry, bus, and rail are increasingly treated as one experience, not multiple disconnected steps.
Governance and strategic direction behind the system
This operational integration is not accidental. It is supported by a long-term strategic mobility transformation agenda that connects sustainability, inclusion, and system efficiency. Head of Foreign Relations Department, Barbaros Büyüksağnak of IMM, framed this direction clearly: “We continue our effort to make Istanbul a greener, smarter, and more inclusive city by developing sustainable urban mobility plans and green action plans.”
Within this framework, decarbonisation, congestion reduction, accessibility, and multimodal integration are not separate policy tracks. They are interdependent outcomes of one coordinated system strategy. This is where Istanbul begins to differ from cities that still operate under fragmented mobility governance structures.
Scale is already happening - but it changes the problem
One of the most important signals from Istanbul is that the scale has already been reached in several dimensions. Nearly 45% of motorised trips are made via public transport. At the same time, micro-mobility systems are being integrated into the broader network, and pedestrian-first redesigns are reshaping key historic districts. Deputy Secretary General, Pelin Alpkökin of IMM, highlighted the direction of this evolution, “We are designing the roads and the historic old town of the city to be more pedestrian-friendly, or to only allow pedestrians.”
This signals a shift from mode expansion to system redesign, where cities no longer simply add mobility options but restructure how space and movement interact.
Why scaling still fails in most cities
Despite these advances, the webinar repeatedly returned to one central issue: why scaling remains so difficult elsewhere. The answer was consistent across speakers: it is not a technology problem. The tools exist. The platforms exist. The data exists. The challenge is system alignment. Most pilot projects succeed because they operate in controlled environments with defined governance, limited stakeholders, and simplified operational boundaries. Scaling removes all of those conditions at once. Cities must then align fragmented institutions, procurement models, and operational responsibilities that were never designed to function as a single system.
From innovation to system reality
This is where the real distinction emerges. Cities are no longer limited by their ability to innovate. They are limited by their ability to institutionalise innovation into permanent, interoperable systems. Istanbul demonstrates what that looks like in practice: not a single breakthrough moment, but continuous alignment across infrastructure, governance, and operations. The result is a mobility system that increasingly behaves as one network, even as it continues to evolve.
Integration is not a destination
The key takeaway from Istanbul is not that integration has been “achieved.” It is that integration is a continuous operational condition, not a project milestone. Cities do not arrive at integrated mobility. They maintain it through governance alignment, system interoperability, and long-term operational discipline. That is the shift now underway: from proving concepts in pilots to sustaining systems in reality.
Closing perspective: Why this conversation now moves to the ITS European Congress in Istanbul 2026
As European cities enter this transition phase, the challenge is no longer whether integrated mobility is possible. It is how to make it work consistently at scale, across different governance models, infrastructure systems, and political environments. This is precisely the space where the ITS European Congress becomes relevant. It is not simply a showcase of innovation. It is a working environment where cities, operators, industry, and researchers confront the real barriers to scaling:
- Governance fragmentation
- System interoperability
- Procurement and deployment constraints
- Long-term operational sustainability
For cities moving from pilots to full deployment, this is where the discussion shifts from experimentation to execution. The real question is no longer what works in principle, but what can be implemented, scaled, and sustained in practice. And that is exactly the conversation now shaping the future of urban mobility in Europe.
