Multimodal mobility profiles – the foundation of integrated urban development

In today’s urban land use planning, there is no way around the mobility turnaround. The times when the focus was on motorized private transport are finally passé. Modern cities are complex mobility ecosystems in which pedestrians, cyclists, motorists, public transport users and, increasingly, providers of sharing services, cargo bikes or autonomous shuttles share the streets. The result is a dynamic, multi-layered network of movement patterns – and this is precisely where the concept of multimodal mobility profiles comes in.

A mobility profile describes how people move around in a certain area or neighborhood, which means of transport they choose, how this use changes over the course of the day and week and how the existing infrastructure reacts to this. Multimodal means that it is not simply a matter of adding different modes of transportation, but rather the interplay, interfaces and transitions between them. Anyone who travels from their home to the subway, then onto an e-scooter and finally to the office on foot generates a different volume of traffic than the classic commuter in their own car. For planning, this means that without differentiated profiles, land use, road cross-sections, parking space regulations and green space requirements quickly become a blind flight.

Creating such profiles is no trivial task. It requires reliable data, analytical expertise and the ability to derive concrete planning objectives from figures and movement patterns. At the same time, legal framework conditions, data protection and urban planning objectives must be reconciled. This is the only way to create neighborhoods that are not burdened by traffic, but inspired by mobility.

The benefits of multimodal mobility profiles extend far beyond pure transportation planning. They are a key tool for combining goals such as climate protection, land conservation, social participation and the promotion of healthy, attractive urban spaces. Anyone who wants to shape the mobility of the future needs data expertise – and the courage to question established routines.

In practice, it has been shown that innovative, liveable neighborhoods are created where mobility profiles are consistently integrated into urban land-use planning. The traffic turnaround is then not just lip service, but becomes a spatial, social and ecological reality. This potential must be exploited – with scientific precision, planning creativity and political backbone.

Data bases, methods and tools – How are mobility profiles created?

The basis of every mobility profile is the data pool – and it’s a tough one. Traditional traffic statistics and household surveys have provided valuable foundations for decades. However, digital technologies, sensor technology and mobility apps have made it possible to record movement patterns in a truly granular and up-to-date manner. GPS data, mobile phone analyses, counting sensors at intersections, evaluations of ticketing systems in public transport, floating car data or anonymized evaluations of bike and car sharing providers open up completely new perspectives – provided they are intelligently clustered and evaluated.

The trick is to integrate data from a wide variety of sources. This is where geographic information systems (GIS), data warehouses and specialized mobility platforms come into play. They make it possible to track movements across different modes of transport and extract typical usage patterns. One example: If half of the residents of a new urban district first walk to the streetcar stop in the morning, then take the streetcar to the city center and change to a bicycle there, the planning should not only provide for wide streets, but above all for attractive footpaths, secure bicycle parking facilities and seamless transfer points.

Qualitative methods also play a role. Observations, interviews, participatory workshops or online participation formats provide valuable insights into the needs and wishes of local people – and help to interpret quantitative data. This turns statistics into a vivid picture that reflects both the everyday reality and the future visions of city dwellers.

Another key tool is scenario analysis. Planners can use it to simulate the effects of infrastructure measures, new mobility options or structural changes on mobility behavior. What happens if a new neighborhood is planned to be car-free? How do routes change when a cycle path network is closed or a new suburban train station is built? These questions can now be answered more precisely than ever before using digital models and simulations – provided that the database is correct.

At the end of the day, the challenge is to gain actionable insights from the wealth of information. This is where interdisciplinary cooperation pays off: Transport planners, urban developers, landscape architects, environmental planners and computer scientists must all pull together to develop viable, sustainable and liveable solutions from the data. Without this solidarity, the best mobility profile will remain a paper tiger.

Multimodal mobility profiles in practice – opportunities, limits and current examples

What do multimodal mobility profiles look like in actual planning practice? A look at current projects in German-speaking countries shows that things are moving, even if the dynamics vary greatly depending on the city, municipality or region. In cities such as Zurich, Vienna and Freiburg, mobility profiles have long been an integral part of urban development planning. They are incorporated into land use plans, development plans and neighborhood developments – and ensure that mobility services, infrastructure and settlement structure are considered hand in hand.

In Vienna, for example, a comprehensive mobility concept based on detailed user profiles was drawn up for the development of Seestadt Aspern. The planners consistently focused on linking public transport, cycling and walking, combined sharing services with mobility hubs and planned the development in such a way that motorized private transport becomes less important. The result: a district in which sustainable mobility is not only possible, but also attractive and convenient.

There are also numerous ambitious approaches in Germany. The city of Karlsruhe, for example, uses mobility profiles to design new urban districts such as Südstadt-Ost specifically for multimodal accessibility. In Hamburg, data from mobility analyses is used in the development of new residential areas to reduce parking space ratios, reserve space for sharing providers and create attractive cycle paths and footpaths. The results speak for themselves: where mobility profiles are consistently applied, motorized traffic and CO₂ emissions decrease while the quality of life increases.

But there are also challenges. Collecting and evaluating the necessary data is time-consuming and data protection is an ongoing issue. Smaller municipalities in particular often do not have the resources to carry out complex mobility analyses or develop innovative transport concepts. This calls for cooperation, funding and digital platforms that share know-how and data and make it available for joint use.

Another problem: the integration of new forms of mobility such as e-scooters, ridepooling or autonomous shuttles is still uncharted territory in many cities. There is often a lack of interfaces, regulations or a clear strategy as to how these services can be embedded in overall mobility. Those who fail to plan ahead risk chaos on the roads and frustration among users. Multimodal mobility profiles are therefore not only a tool, but also a compass in the jungle of urban mobility.

Governance, participation and data protection – who controls the mobility profiles?

As technical as the topic is, its success stands and falls with the right governance. Who decides how mobility profiles are created and used? Who controls the data, who defines the goals, who is responsible? In practice, it is clear that without clear rules, transparent processes and an open communication culture, the potential of mobility profiles remains untapped – or, in the worst case, is even misused.

Data protection is a major issue here. Movement data is sensitive and the protection of privacy is non-negotiable. This is why all data collection must be anonymized, aggregated and clearly traceable. Cities and municipalities are well advised to rely on data protection-compliant technologies and open standards right from the planning stage. This is the only way to build trust – and the only way to really reap the benefits of intelligent mobility profiles.

Public participation is becoming increasingly important. If you want to get people excited about new forms of mobility, you have to involve them – not just as data donors, but as active co-creators. Digital participation platforms, local workshops or real-world laboratories offer the opportunity to jointly develop, discuss and refine mobility profiles. In urban land-use planning in particular, conflicts of objectives can be identified at an early stage and viable compromises can be found.

Interdisciplinary cooperation is a must. The best results are achieved when transport planners, urban developers, environmental experts, social scientists and IT experts sit around the same table. Only then can mobility profiles be designed in such a way that they really meet the needs of urban society – and do not just follow technical or political fashions.

Last but not least, political backing is needed. Innovative mobility concepts are rarely convenient and often meet with resistance. Those who boldly move forward need clear objectives, transparent communication and the willingness to make uncomfortable decisions. Only then will mobility profiles become real levers for sustainable, liveable cities.

Outlook: Multimodal mobility profiles as the engine of the city of the future

The future of urban land use planning is multimodal, data-driven and participatory – there is no way around it. Multimodal mobility profiles are far more than just a technical tool: they are the key to linking the complex requirements for sustainable, resilient and liveable cities. Those who no longer see mobility as a disruptive factor, but as a quality, can use space more efficiently, more socially just and more ecologically compatible.

The development of intelligent mobility profiles makes it possible to forecast mobility behavior precisely, plan infrastructure in line with demand and integrate new forms of mobility in a targeted manner. This creates flexible neighborhoods that make people’s everyday lives easier, protect the environment and climate and create space for new qualities of life. Digitalization is not an end in itself, but a tool – and one that must be used with caution, expertise and a sense of proportion.

German, Austrian and Swiss cities are faced with the task of systematically tackling the issue of mobility profiles. Standards, guidelines and best practices are needed to make it easier to get started and ensure quality. At the same time, local authorities, science and business need to cooperate more closely in order to pool resources and exploit synergies. Funding programs at state and federal level are needed to support smaller towns and rural areas.

The challenges are great – but so are the opportunities. Those who invest now can set the course for mobility that is no longer a burden but a pleasure. The city of the future will not be planned on the drawing board, but in a dialog between data, people and space. Multimodal mobility profiles are the engine that transforms visions into reality.

There is still a long way to go, the tasks are complex – but one thing is certain: without multimodal mobility profiles, integrated urban land use planning will remain a piecemeal process. If you want truly sustainable, liveable and future-proof cities, you have to rethink mobility – and design it boldly. Garten und Landschaft will stay tuned, as always. We promise.

To summarize: multimodal mobility profiles are far more than just a technical gimmick. They are the foundation of integrated, sustainable and humane urban land-use planning. They can be used to master the challenges of transport and urban development, develop innovative solutions and create quality of life. The key lies in the intelligent use of data, collaboration across disciplines and the involvement of local people. Cities that seize these opportunities early on will become role models for mobility that is no longer a problem but a potential.

Anyone who puts a building into service assumes responsibility for more than just aesthetics and functionality. The fire safety compliance certificate is the legal and technical instrument used to demonstrate that the installed construction products and building systems actually meet the requirements that were a prerequisite for the planning and approval processes. It lies at the intersection of product law, building code regulations, and structural testing practices, and is equally binding and significant for architects, specialist planners, and building owners.

  • What role conformity marks, test certificates, and certificates of suitability play

  • What typical errors occur in practice and how they can be avoided
  • How the confirmation of conformity fits into the overall system of structural fire protection

Definition and Legal Basis: What the Fire Protection Declaration of Conformity Is

The fire protection conformity certificate is a written declaration confirming that a construction product or building system complies with the requirements relevant to its use in fire protection. These requirements may stem from a general building authority approval (abZ), a general building authority test certificate (abP), a European Technical Assessment (ETA), or a case-by-case approval (ZiE). The declaration is not a marketing document or voluntary certification, but rather an instrument required by building codes that documents the transition from abstract product characteristics to concrete use in construction.

The legal basis lies in the state building codes of the German federal states, which are largely based on the Model Building Code (MBO). The MBO distinguishes between regulated and unregulated construction products. Regulated construction products comply with a technical building regulation or a harmonized European standard and may be used without further proof, provided they bear the conformity mark (Ü mark). Non-regulated construction products require separate proof of suitability for use, which is provided by the aforementioned instruments. For construction products relevant to fire protection, a higher level of requirements applies because failure in the event of a fire can pose an immediate threat to life.

The Ü mark, which is affixed to regulated construction products, is the visible symbol of the declaration of conformity. It indicates that the manufacturer declares that its product complies with the applicable technical regulations. For construction products that are not covered by harmonized European standards but perform fire protection functions, the fire protection declaration of conformity is the key proof that bridges the gap between product approval and installation. Without it, there is no formal proof that the product used is in fact what the approval specified.

The System of Proofs of Suitability: Approvals, Test Certificates, and Standards

To properly understand the fire safety declaration of conformity, one must understand the system of proof of suitability in which it is embedded. This system has several levels that apply differently depending on the product type and application. At the foundation are harmonized European standards (hEN), which are adopted under the Construction Products Regulation (EU Regulation No. 305/2011, or CPR for short). Products that comply with such a standard bear the CE marking; however, this marking does not constitute approval for use under national law but merely declares the product’s performance characteristics.

For products without a harmonized standard or for applications that fall outside the scope of a standard, national instruments apply. The General Building Authority Approval (abZ) is issued by the German Institute for Building Technology (DIBt) in Berlin and fully describes the permissible conditions of use for a product. The General Building Inspection Test Certificate (abP) is a simplified instrument for products whose suitability for use can be demonstrated through testing without the need for a full approval. Both documents contain precise information on installation conditions, processing instructions, and maintenance requirements that are directly relevant to the subsequent confirmation of compliance with fire safety standards.

Since the amendment of the Construction Products Act, the DIBt has gradually supplemented or replaced the general building authority approval with the general type approval (aBG) and the general building authority test certificate with the general type test certificate (aBPZ). These terms no longer refer solely to the product itself, but to the construction type—that is, the combination of product, installation situation, and installation rules. This distinction is significant for fire protection: A fire protection system, such as a cable penetration or a fire damper, will only function as tested if all components and the installation precisely comply with the specifications of the proof of suitability for use. The fire protection conformity confirmation is the document that confirms exactly this for the specific construction project.

Who issues the Fire Safety Conformity Certificate, and who bears responsibility?

The issue of responsibility is particularly sensitive in fire protection because defects can have irreversible consequences in an emergency. Depending on the product and the level of requirements, the Fire Safety Conformity Certificate can be issued in two ways: by the manufacturer itself or by a recognized testing, inspection, and certification body (PÜZ body). The applicable method is determined by the respective proof of suitability for use. For simpler products with a lower risk potential, the manufacturer’s declaration is sufficient; for safety-critical construction products with high fire safety requirements, third-party monitoring by an accredited body is mandatory.

By issuing a declaration of conformity, the manufacturer makes a legally binding statement that its product meets the requirements of the declaration of suitability for use. This declaration requires an in-house production control system (WPK)—that is, an internal quality management system that ensures consistent manufacturing quality. The WPK is not an informal tool, but a normatively required component of the proof of conformity. For products subject to third-party supervision, the in-house production control is supplemented by regular audits conducted by the PÜZ body, which makes the right to award the conformity mark contingent upon ongoing compliance with the requirements.

On the construction site, the contractor is responsible for ensuring that only products with a valid certificate of conformity are installed and that the installation complies with the specifications of the certificate of suitability. The architect or specialist planner is required to request, review, and document the certificates of conformity. The building inspection authority may require the submission of these documents as part of its construction supervision. In practice, the documentation chain is often incomplete because the importance of the fire protection certificate of conformity is underestimated on the construction site, and the pressure of the construction schedule takes precedence over the careful filing of supporting documents.

The Role of the Fire Protection Planner and the Expert

In buildings classified as Class 4 and 5, as well as in special-purpose structures, many federal states require the involvement of a qualified fire protection planner or a recognized fire protection expert. This expert not only reviews the fire protection concept during the planning phase but also oversees the construction process and ultimately confirms that the completed building complies with the approved fire protection concept. The certificates of conformity for the installed fire protection products are an essential part of the expert’s basis for review. Without complete supporting documentation, the expert cannot issue the final certificate, which prevents the building from being put into use.

Typical Fire Protection Products and Their Compliance Requirements

The range of construction products for which a fire protection conformity certificate is required extends from building materials and components to complex systems. Among the most common product groups are fire dampers in ventilation and air-handling systems, cable penetrations and pipe penetrations in ceilings and walls, fire-rated doors and gates, fire-resistant glazing, fire-resistant coatings (so-called reactive fire protection systems that foam up and insulate in the event of a fire), fire-resistant plasters and panels, as well as insulation materials with a fire protection classification.

Each of these product groups has specific requirements regarding proof of suitability for use and the type of conformity assessment. A fire damper, for example, must not only be the correct product; it must also be installed in the correct wall construction, with the correct fasteners, and with the correct control system in order to achieve the tested fire resistance rating. Deviations from the installation instructions in the proof of suitability—even if they seem plausible from a structural engineering perspective—void the validity of the confirmation of conformity. This principle of systemic conformity is not sufficiently understood by many tradespeople on the construction site and leads to one of the most common errors in structural fire protection.

Reactive fire protection systems—specifically coatings applied to steel structures that form an insulating layer by foaming in the event of a fire, thereby delaying the critical heating of the steel—deserve special attention. The effectiveness of these systems depends heavily on the coating thickness, the substrate, the application method, and the environmental conditions. The fire protection compliance certificate for such systems requires complete documentation of the coating thickness through measurement reports, which must be prepared by the applicator and archived by the client. If these records are missing, the certificate of compliance is not formally valid, even if the product was applied correctly.

Common Mistakes in Practice and How to Avoid Them

Practical experience reveals a recurring pattern of errors that can be divided into three categories: documentation gaps, product mix-ups, and installation errors. Documentation gaps arise when certificates of compliance are available but are not systematically collected, organized, and handed over to the building owner. Complete fire protection documentation is essential for subsequent use, maintenance, and any potential renovations. If it is missing, a time-consuming assessment by experts must be conducted in cases of doubt—a process that is expensive and rarely provides complete certainty.

Product mix-ups occur when a similar but not identical product is installed on the construction site because the one originally planned is temporarily unavailable. Any product change in the area of fire protection requires a new review to determine whether the new certificate of suitability applies to the specific installation situation and whether a fire protection conformity certificate is available for the replacement product. This verification step is often skipped in day-to-day construction site operations because it takes time and the urgency of the problem is not immediately apparent.

Installation errors are the most serious category. They occur when the installation instructions in the certificate of suitability are not followed—whether due to ignorance, a tendency to cut corners, or because the instructions in the document are difficult to understand. Typical installation errors with cable penetrations include the use of incorrect filling materials, insufficient fastening, or the mixing of products from different manufacturers that have not been tested together. For fire-rated doors, common errors include incorrectly adjusted door closers, missing or improperly installed seals, and subsequent modifications to the frame or door leaf that invalidate the certification.

To avoid these errors, a structured fire protection management system on the construction site is recommended, comprising the following elements:

  • Early specification of all fire protection-related products in the request for proposals, with an explicit requirement for a certificate of conformity
  • Establishment of a central document folder for all fire safety certifications on the construction site
  • Training of the contractors on the specific installation instructions for the products used
  • Random inspections of installation sites by the site manager or fire safety planner during construction
  • Full handover of the documentation to the building owner as part of the building documentation

The Fire Safety Declaration of Conformity in the European Context

The German system of conformity certification does not exist in isolation but is in tension with the European Construction Products Regulation. The Construction Products Regulation governs the CE marking of construction products and creates a single European market for these products. However, it expressly does not regulate the use of these products under national building codes. This means that a product with CE marking and a declared fire protection performance may not automatically be installed in Germany if a national approval or proof of suitability for use is required for the specific application.

In practice, this duality leads to confusion. Manufacturers from other EU countries who supply their products with CE marking and a declaration of performance are often surprised that additional documentation is required for the German market. Conversely, German planners and building owners must carefully verify, in the case of imported products, whether the CE marking is sufficient for the intended use or whether a national certificate of suitability—and thus a confirmation of compliance with fire protection requirements under German law—is required. The DIBt and the state building authorities have published guidance on this matter; however, this guidance must be updated regularly because the European standards framework is constantly evolving.

European Technical Assessments (ETAs) issued by the DIBt or another authorized Technical Assessment Body may, in certain cases, be recognized as proof of suitability for use under German law. For fire protection products, however, this is subject to strict conditions, because while the European classification standards (in particular the EN 13501 series) harmonize test methods and classifications, the national requirements for fire resistance classes and installation conditions remain enshrined in national law. The fire protection certificate of conformity thus remains a genuinely national instrument, even if the products to which it refers may have been tested and classified at the European level.

Context: Why the Fire Safety Declaration of Conformity Is More Than Just Bureaucracy

It would be a mistake to view the fire safety declaration of conformity as a mere administrative requirement to be fulfilled with as little effort as possible. It serves as the link between the abstract verification of product properties and concrete safety within the building. A fire protection system that has achieved the required fire resistance class in the laboratory will only provide protection in an emergency if it has also been correctly installed and documented on site. The certificate of conformity is the formal proof that this transition has been successfully completed.

For architects and specialist planners, this entails a dual responsibility: they must not only specify the correct products but also ensure that the installation and documentation meet the requirements. This responsibility does not end with the handover of the building, because subsequent changes to fire protection-relevant building components—such as replacing a fire door or retrofitting conduits with certified fire barriers—require new, valid certificates of conformity. Failure to do so not only jeopardizes the building’s operating permit but also results in significant liability in the event of damage.

This issue is gaining importance due to the increasing complexity of modern buildings and the growing density of technical installations. Buildings with extensive building services, data centers, laboratories, or special usage requirements have a multitude of penetrations, fire-resistant barriers, and fire protection systems, each of which requires its own documentation. In this context, the fire protection compliance certificate is not a single document but a structured verification system that must accompany the building throughout its entire service life. Those who consistently implement this system from the very beginning not only ensure legal compliance but also lay the foundation for a permanently effective level of fire protection that truly lives up to its name.

The light of history

Building design

The extensions stand out clearly from the brick and glass architecture of the historic waterworks.

The small town of Mons in Belgium has a turbulent past. In the Mons Memorial Museum by architect Pierre Hebbelinck, the light and dark sides of its history find architectural expression.

Buffer zone, border area, battlefield: Belgium has historically always been a crossroads of European history – and therefore also a stage for its often tragic chapters. This is particularly evident during a visit to the Mons Memorial Museum, which opened in 2015 and is located in the small town of Mons in the southern part of the country.

Pierre Hebbelinck from Liège was commissioned in 2011 to convert a historic industrial building into a museum dedicated to the history of the region. The brick, iron and glass waterworks is a typical witness to the economic boom that the Walloon region experienced during the industrialization process in the 19th century and had to be renovated and extended in line with the preservation order.

The architects opted for two wing extensions, whose exterior façades were painted white to clearly distinguish the new buildings from the existing ones. They clearly divided the functions between the three buildings, with the interior design of the individual rooms corresponding to the exhibition content: the windowless, oppressive rooms of the new buildings focus on the most dramatic chapters of local history – war, deportation, occupation – while the large hall of the old building is dedicated to liberation, democracy and freedom.

The view outside

The hall in the middle of the complex, glazed at the gable ends, serves as a transparent reception and catering area and is crossed by a 15-metre-long walkway. This connects the permanent exhibition in the left wing with the rooms for temporary exhibitions in the right wing.
The architects attached great importance to the lighting concept: in addition to the lighting, which is differentiated according to function, the historic glass fronts of the listed old building were also professionally refurbished to optimize the incidence of sunlight and improve the quality of stay for visitors to the café and bookshop. The large glass windows, which are divided by metal bars, were also renewed.

Open and closed

The closed nature of the extensions forms a contrast to the open and transparent existing building. A strategically placed aisle in the exhibition tour leads to an open space in the basement, whose brick-clad, monotonous red walls can be read as an architectural image of the tragic wartime past of the Mons region. There are also narrow windows that allow light into the interior like crevices in a rock, or provide a view to the outside at certain points: For example, to a war memorial at the crossroads or to important elements of the city’s history in the public space.
