Working together on smart, sustainable cities
DMI ECOSYSTEM
We connect governments, businesses, and knowledge institutions. Together, we work on sharing knowledge, sharing data securely and confidentially, creating standards, and developing innovative solutions. This allows us to accelerate processes, ensure tight control, and make better decisions.

about us
These participants set the ecosystem in motion
The Netherlands faces major and urgent challenges. CO2 and nitrogen emissions must be significantly reduced. We need 900,000 additional homes in cities, the climate urgently requires adjustments to the built environment, and energy supply can no longer be taken for granted.
The DMI ecosystem is designed for governments, businesses, and knowledge institutions.

The Urban Data Access Platform (UDAP) is the central hub for exchanging intelligent mobility data, sharing information from various sources (such as intelligent traffic control systems (iVRI) and route information apps) for safer and more efficient traffic. The national Strategic Committee (SC), now called the national Standardization Committee UDAP Data Chain, has been active in this public-private data chain since 2018. The goal of the SC (the abbreviation remains unchanged) is to establish national standards to enable reliable data exchange between different links in the data chain. The SC has now established around 40 national standards. These standards are managed by CROW on behalf of the SC and are available (free of charge) on the CROW website. Since the end of 2025, the SC has gained a number of new members, which will further shift the focus to the 'end user'.
PDX
The municipality of Apeldoorn can now also be found on the Producten en Data Exchange (PDX) with a range of mobility-related data items and knowledge products. This is a selection of datasets that are currently difficult to find, even though virtually every municipality has this data at its disposal. According to Bas Tutert, senior mobility advisor at the municipality of Apeldoorn, that is precisely the intention: to get others moving.
DMI ecosystem
At the end of last year, six groups of four master's students from the University of Amsterdam (UvA) spent several weeks working on issues faced by municipalities participating in DMI. This took place within the framework of the Requirements Engineering course in the Software Engineering master's program. The goal: to help municipalities realize their digital ambitions.
Smart urbanization
CROW has collaborated with experts in the field to develop the new publication "STOMP in practice": a practical step-by-step plan for road design based on the STOMP principle. This principle focuses on sustainable mobility by giving priority first to walking, then cycling, followed by public transport, MaaS, and finally private cars.
Communications
As of January 1, 2026, we have transferred the management of the website, the CRM system, and the online collaboration environment to Didiwedo. This digital agency from Rotterdam will take over the work previously carried out by ConnAct. With this decision, we are ensuring the long-term technical availability of the platform.
DMI ecosystem
The Ministry of Infrastructure and Water Management (IenW) recently sent a letter to interested parties informing them of the planned launch of pilot projects involving autonomous road transport in 2026. The letter follows widespread and enthusiastic responses from the field to earlier announcements.

With no fewer than 108 data products, the municipality of Nijmegen is currently one of the largest data providers in the Products and Data Exchange (PDX) of the DMI ecosystem. Agethe Derkse, Chief Data Officer of Nijmegen, believes it makes sense to share data in this way. "That data belongs to the citizens.
Traffic and logistics
The pressure on space in our inner cities is rapidly increasing. Logistics traffic, terraces, cyclists, and pedestrians claim every square meter, multiple times a day. Municipalities are looking for ways to organize loading and unloading areas more efficiently, fairly, and above all, more intelligently. A new legal analysis by law firm AKD provides clarity: many

How can you build faster and more sustainably in a city where space is scarce and the challenge is great? During a meeting of the Spring Agreement on Circular Industrial Construction, Mattijs Rommelse, construction director for the municipality of Rotterdam, provided insight into his city's approach. "Collaborate, agree on rules, digitize, and share knowledge."
DMI ecosystem
Arjan Spruijt of DMI and Michelle van Dijk of the Ministry of Infrastructure and Water Management (IOP?) recently spoke at a meeting of the Spring Agreement, the cooperation program between the six largest trade associations in the construction sector and the Ministry of Infrastructure and Water Management to accelerate Circular Industrial Construction. The central question: how can digitization help with this?
