Anastasia Tzioutziou: "Next time you miss your bus, think that the route can get better"
Nancy Tzioutziou is a researcher at the Aristotle University of Thessaloniki (AUTH), where she contributes to transport analysis and the development of response strategies for urban disruptions such as flooding, earthquakes, and congestion.
Within AntifragiCity, her work focuses on developing a dynamic transport analysis methodology to understand how mobility patterns change during disruptive events and how cities can prioritise actions in response. Her team is also advancing on a decision support tool, "based on agent-based and dynamic modelling approaches", she explains, alongside a mobility triage handbook to support real-world applications.
"We are excited to work with real data that comes from the demo sites of the project and find useful solutions for real case studies, so that we can integrate this information into the later steps of the project and create an API that can be used by everyone at the end of the project."

Ali Ghoroghi: "We bring together what citizens say, what experts know, and what the data tells us"
Ali Ghoroghi is a Senior Research Fellow at Cardiff University, the coordinating institution of AntifragiCity. As project manager on Cardiff’s side, he helps coordinate research activities across the consortium and ensures alignment between partners.
Cardiff University leads key areas of the project, including the development of the conceptual and data foundations for understanding antifragile urban mobility. This work defines the frameworks, methods, and tools that support the project.
"I am especially excited about bringing together three types of knowledge: what citizens say, what experts know, and what the data tells us about how cities behave in real life. By combining these, we hope to show how cities not only cope with shocks but actually become better because of them. Turning this into a practical framework or antifragile mobility framework and tools for me is the most rewarding part of this project."

Women at AntifragiCity shaping the future of urban mobility
Cities move us. They connect us to work, education, healthcare, and each other. But as urban systems face growing pressures, the challenge is no longer just about building resilient cities. It is about creating cities that learn, adapt, and grow stronger through disruption.
This is antifragility. Yet the research, planning, and innovation needed to achieve it take place in fields where women remain significantly underrepresented. Today, women make up only 31% of researchers globally. In engineering, the figure drops to around 20%, and in artificial intelligence (AI), it is just 22% of professionals who are women. In transport planning and urban infrastructure development, women continue to be underrepresented in technical and leadership roles, despite designing systems that shape entire societies.
Gender balance in these fields is not just about fairness. It is about effectiveness. When research and planning lack diverse perspectives, mobility systems risk serving some communities well while failing others. Inclusive teams ask better questions, identify overlooked vulnerabilities, and design solutions that respond to the full complexity of urban life.
Voices behind AntifragiCity
For International Women's Day 2026, we spoke with four women from the AntifragiCity team about their work, their motivations, and what it takes to build truly inclusive, adaptive cities. They come from different disciplines: architecture and engineering, political science, transportation planning, and urban planning. They work across different countries and bring different expertise to AntifragiCity. Yet their insights reveal a shared understanding that cuts across professional boundaries and show that diverse voices do not just strengthen urban mobility research, they transform it.
Nancy Tzioutziou (Aristotle University of Thessaloniki)
Nancy Tzioutziou is a postdoctoral researcher and architect engineer at Aristotle University of Thessaloniki. Her work explores the resilience of complex urban systems, examining everything from physical infrastructure to the behavioural patterns of communities.
"My work revolves around the resilience of complex urban systems, such as the mobility network with all its interdependencies, from physical infrastructure to behavioural patterns of the local community. The most exciting aspect of AntifragiCity is its emphasis on emerging characteristics within urban environments, moving beyond bouncing back to the pre-disruption operational status to bouncing forward to an adaptive and improved state of operation, according to the principle of antifragility."
Lisa Verhasselt (Luxembourg Institute of Socio-Economic Research)
Lisa Verhasselt, a research associate at the Luxembourg Institute of Socio-Economic Research, brings a political science perspective to AntifragiCity. Her work focuses on citizens' participation, particularly through our Citizens’ Forums. "What excites me most is the opportunity to explore how involving citizens directly in discussions and decision-making can contribute to stronger, more adaptive urban responses to challenges," she says.
Dr Maria Tsami (Aristotle University of Thessaloniki)
For Dr Maria Tsami, a senior researcher in transportation, an urban & spatial planning engineer (PhD, MSc), and an MSc in information and communication systems, mobility is not just about movement. It is about enabling lives.
"As a senior researcher in transportation planning and sustainable urban mobility, my work focuses on understanding mobility needs and shaping smart, inclusive transport systems by integrating behavioural analysis, transport economics, and sustainable and resilient mobility planning. For me, mobility is not just about movement; it is about enabling lives."
In a world of continuously changing conditions and growing vulnerabilities, her research explores how mobility systems respond to uncertainty while sustaining resources and continuously improving.
"AntifragiCity is particularly inspiring because it embraces this perspective: transport systems that learn, evolve, and expand opportunity for every citizen, turning uncertainty into a catalyst for smarter and more resilient cities. This vision is exactly what makes this work so meaningful to me."

Natalia Horshkova (Odesa 5T)
For Natalia Horshkova, part of the Grant Office Odesa 5T, "project management is more than just managing tasks," she says. "It’s about inspiration, people, and the journey from a spark of an idea to a tangible result."
What inspires Natalia most is "contributing to an innovative approach to urban mobility. It’s about creating systems that provide real-time responses to the ever-evolving challenges of a modern city's dynamic pace."
What inspired their career paths
Inspired by close family members who work in architecture, engineering, and construction, Nancy pursued studies in architectural engineering, where she discovered the complex interplay among urban planning, infrastructure engineering, and socioeconomic development. "My research interest then focused on the field of resilience, not only as an observed static property but as an emergent systemic aspect that can be actively engineered," she says. "This involves developing methodologies to quantify and enhance the capacity of urban systems to improve their performance and adapt their structure and rules in response to disruptive events."
Lisa’s interest in political science stems from a long-standing curiosity about how individuals can actively participate in democratic processes and influence public decisions. "This interest grew from a desire to better understand how participation can make governance more inclusive, responsive, and meaningful for people."
Maria chose a career in transportation planning and urban mobility research "because mobility lies at the heart of how cities function and how people access opportunity," she mentions. "Transportation systems shape daily life, determining how people reach education, employment, healthcare, and social activities. Very early in my studies, I realised that well-designed mobility systems can transform cities and improve people’s lives. Contributing to transport solutions that are efficient, inclusive, and sustainable continues to be a powerful motivation in my work."
Natalia approaches urban planning through the lens of antifragility, focusing on managing what she calls 'unknown-unknowns'.
"In the face of simultaneous climate and security crises, being resilient is no longer enough," she explains. "We need systems that gain from disorder. My work in urban planning focuses on managing 'unknown-unknowns' by building redundancy and diversity into our cities. I am proud to be part of the AntifragiCity team, where we turn these complex challenges into a roadmap for innovation. For me, it’s the next level of urban mobility: transforming the way cities respond to the unpredictable rhythm of life."
Breaking barriers for women in the field
When asked about barriers facing women in her field, Nancy points to the well-known 'leaky pipeline' in research, "where structural inequities and implicit biases cause a disproportionate loss of female talent at senior career stages."
"Breaking down barriers for women in STEM fields, particularly in highly interdisciplinary domains such as urban systems engineering, requires fostering inclusive environments that actively promote mentorship, leadership opportunities, and equitable recognition for their contributions," she says.
"Breaking down barriers for women in STEM fields requires fostering inclusive environments that actively promote mentorship, leadership opportunities, and equitable recognition."
Maria highlights the persistent underrepresentation of women in technical and leadership roles in transport planning and infrastructure development. "Despite progress, women are still less visible in strategic planning, engineering leadership, and major mobility and infrastructure projects," she says. "Breaking this barrier is essential because better representation leads to better decisions and, in the end, to better cities. When diverse voices contribute to mobility policy and infrastructure decisions, the result is transport systems that are more inclusive, safer, and more effective for everyone."
"When diverse voices contribute to mobility policy and infrastructure decisions, the result is transport systems that are more inclusive, safer, and more effective for everyone."
Words of advice for the next generation of women entering the field
Nancy's advice to young women considering a career in the field: "Embrace the interdisciplinary nature of urban resilience, actively seeking collaborations across engineering, social sciences, and policy to develop holistic solutions for complex urban challenges. Urban resilience is an aspect that demands all the voices and perspectives to be included to respond to the challenges of the future."
"Urban resilience demands all voices and perspectives to respond to the challenges of the future."
Lisa encourages them to be confident in their ideas and perspectives, "and don’t hesitate to take up space in discussions and decision-making processes. Building supportive networks and seeking out mentors can also make a big difference in navigating the field."
Maria's message to young women is clear: "Your voice matters. Real change begins when people care about their cities, get involved, and take the initiative to help shape the places they live in. In the end, the greatest motivation is knowing that your work can create real meaning by helping build cities that support people, communities, and future generations."
"Real change begins when people care about their cities, get involved, and take the initiative to help shape the places they live in."
Why diverse perspectives matter in urban mobility
For Nancy, "diverse perspectives, encompassing varied socio-economic backgrounds, cultural understandings, and disciplinary expertise, are crucial for identifying nuanced vulnerabilities and designing equitable, robust, and resilient urban mobility systems that can adapt to both foreseen and unforeseen disruptions. This inclusivity is particularly vital when addressing issues such as gender-specific mobility patterns and safety concerns, which often go unaddressed in traditionally male-dominated planning processes (ITF, 2021)."
Lisa shares that "diverse perspectives help ensure that research and solutions reflect the needs and experiences of different groups of people. This leads to more inclusive, equitable, and effective mobility policies and innovations that better respond to the complexity of urban life."
Maria emphasises that urban mobility affects people differently. "When research and planning include diverse perspectives, we gain a deeper understanding of real mobility needs and challenges that might otherwise remain invisible.
Innovation in mobility begins when we start asking better questions about who our systems truly serve—and who they may leave behind. By bringing different experiences and viewpoints into research and decision-making, we can design transport systems that are more inclusive, effective, and responsive to the communities they serve, while continuously learning and building the capacity to serve them even better in the future."
Natalia is convinced that "diverse perspectives are essential for a comprehensive urban mobility strategy and act as a catalyst for innovation."
Different voices, shared vision
Urban mobility systems that can truly adapt and improve through disruption require more than technical solutions. They require diverse perspectives, citizen participation, and a commitment to inclusivity at every level of research and decision-making.
When Nancy speaks of resilience as an emergent systemic aspect that demands all voices and perspectives, when Lisa emphasises involving citizens directly in discussions and decision-making, when Maria argues that innovation begins with asking better questions about who our systems serve and who they leave behind, and when Natalia describes managing unknown-unknowns through diversity and redundancy, they are describing the same vision from different angles.
Antifragile cities are not just technically sophisticated. They are inclusive by design. And they understand that without diverse voices in research, planning, and leadership, we will continue to build mobility systems that work for some while failing others.
Antifragility in urban systems cannot be achieved through technical excellence alone. It emerges from the interplay of rigorous engineering, meaningful citizen participation, interdisciplinary collaboration, and teams that reflect the diversity of the communities they serve.
The work continues. And so does the commitment to ensuring that all voices contribute to building the antifragile cities of tomorrow.

AntifragiCity: From Resilience to Antifragility
Cities move us. Every day, we commute, connect, and navigate urban life. But when disruption hits, from congestion and climate events to energy shocks or pandemics, resilience alone is no longer enough. What if cities could learn from disruption? What if stress didn't weaken systems, but strengthened them? This is the idea behind antifragility.
AntifragiCity is a Horizon Europe project rethinking urban mobility across Europe. Bringing together 13 partners in 8 countries, we are designing systems that don’t just recover, but adapt, improve, and grow stronger through disruption.
Our approach combines technology to detect and assess disruptions, real-world testing in pilot cities, citizen participation at the centre of our decision-making, and data-driven insights for better urban planning.
What we learn feeds into European research and policy, helping cities become more sustainable, inclusive, and prepared for the unexpected.
The future of cities won’t avoid uncertainty; it will grow through it.

AntifragiCity develops KPIs and framework for urban mobility
How do we measure progress towards antifragile urban mobility? With the right indicators.
The AntifragiCity KPIs and framework for urban mobility aims to foster environments that thrive amid disruptions, addressing urban degradation, systemic complexities, and limitations in existing assessments that lack adaptability, inclusivity, and holistic scope.
Using a three-stage mixed-methods approach, the research systematically reviewed 2,540 indicators from academic articles, EU projects, and grey literature, complemented by a practitioner survey across 8 European cities. The resulting framework is adaptive, dynamic, and modular, structured via an IPOO model and integrated with the AntifragiCity Ontology for semantic data management.
Validated against the Sustainable Development Goals, European Green Deal, and Global Plan for Road Safety, it supports data-driven decisions and includes the SUMA API as an open-source tool for transferable resilience quantification.

AntifragiCity launches KPIs' definition tool for urban mobility
How do cities select the right indicators to measure progress towards antifragile urban mobility? With a systematic, flexible tool designed for real-world application.
AntifragiCity has developed a KPIs' definition tool that enables cities to define, refine, and customise key performance indicators (KPIs) based on strategic vision, objectives, and real-world applicability for urban mobility management.
The tool uses a flexible, three-stage mixed-methods iterative approach. The methodology for KPI selection involves five steps: delineating strategic vision, establishing operational objectives, specifying requirements, systematically identifying and selecting KPIs from a comprehensive catalogue, and refining or extending the preliminary set. This approach combines criteria-based filtering, multi-criteria decision analysis, an ontology-driven backbone, and expert input.
The API structure is layered to facilitate seamless integration and real-time data exchange, comprising city stakeholders as final users, an API gateway as the entry point, a KPI service layer for selection logic and data processing, and a KPIs' catalogue store for persistent storage and retrieval. The structure incorporates feedback loops to refine and validate KPIs, ensuring their continuous relevance and accuracy in monitoring urban dynamics.
*Original version of the AntifragiCity KPIs' definition tool, as described in Deliverable 2.7.

The AntifragiCity ontology: a semantic foundation for urban mobility
How do we create a shared language for antifragile urban mobility research? Through a comprehensive ontology.
The AntifragiCity Ontology provides a semantic foundation for modelling antifragile, equitable, and data-intensive urban mobility systems. Building on structured requirements and concepts from project documentation and stakeholder inputs, the ontology formalises key entities, processes, events, states, and indicators related to disruptions, responses, socio-technical systems, governance, equity, and long-term learning.
A 12-class meta-model provides a stable upper structure, instantiated through modular components covering transport networks, social and equity aspects, environmental and climate stressors, governance and policy instruments, observations and KPIs, data provenance, and antifragility dynamics. Specified in OWL and designed for deployment as a knowledge graph, the ontology integrates with digital twins, multi-agent systems, and AI analytics.
Instantiation guidelines and illustrative use cases are provided for the pilot cities of Bratislava, Larissa, Odesa, and Thessaloniki.

Publication: The fragile nature of road transportation networks
Why do traffic disruptions have such extreme effects on urban mobility? Road transportation networks are fundamentally fragile. Our new publication provides a rigorous mathematical proof of the fragility of road transportation networks, demonstrating that performance loss increases exponentially as disruptions grow linearly in magnitude.
Major cities worldwide experience problems with the performance of their road transportation networks, and the continuous increase in traffic demand presents a substantial challenge to the optimal operation of urban road networks and the efficiency of traffic control strategies.
Based on established traffic flow theory, specifically the Macroscopic Fundamental Diagram (MFD), the study conducts a rigorous mathematical analysis to theoretically prove the fragile nature of road transportation systems. The research proposes a skewness-based indicator that can be readily applied to cross-compare the degree of fragility for different networks, based on MFD-related parameters.
A numerical simulation calibrated with real-world network data bridges the gap between theoretical proof and practical operations, with results showing the reinforcing effect of higher-order statistics and stochasticity on network fragility.
This work demonstrates the fragility of road transportation networks and guides researchers toward adopting antifragile design methods for future networks and traffic control strategies, a key objective of AntifragiCity.

AntifragiCity holds its 1st General Assembly in Bratislava
On 10-11 December 2025, the AntifragiCity consortium gathered in Bratislava for its 1st General Assembly, hosted at TU-BA, Bratislava’s Centre for Architecture and City Planning. Over two days, partners from across Europe came together to review progress since the project’s launch in May 2025, align on ongoing work, and plan the next steps in our shared mission: helping cities move beyond resilience towards truly antifragile urban mobility systems.
The meeting marked an important milestone for AntifragiCity, bringing together perspectives on research, technical development, social innovation, and implementation in one place.
Two days of collaboration, alignment, and planning
On the first day, we focused on reviewing our progress and next steps across three key areas:
- Event analysis and framework development, led by Cardiff University, setting the basis for how disruptions in urban mobility systems are understood.
- Mobility triage and short-term responses, coordinated by Aristotle University of Thessaloniki, exploring how cities can prioritise mobility needs and manage transport systems under stress.
- Long-term improvements in antifragile traffic control in urban road networks, led by ETH Zürich, highlighting approaches that allow systems not only to recover from disruption, but to improve because of it.
On the second day, we shifted our focus towards implementation, validation, and real-world impact:
- Rhoé shared progress on the simulator for urban mobility antifragility, a tool designed to help cities understand and strengthen the antifragility of their mobility systems.
- The Luxembourg Institute of Socio-Economic Research (LISER) led discussions on case study validation and public acceptance, outlining how we will test our approaches in real-world contexts and incorporate citizens’ perspectives we will gather through our Citizens' Forums.
- The Institute of Entrepreneurship Development (iED) facilitated a session on the pathway to market, aligning objectives, responsibilities, and milestones to ensure our results can be translated into practical and scalable solutions.
- AUSTRALO presented updates on outreach and awareness, reviewing our communication strategy and upcoming activities to keep our audiences informed and engaged.
- The meeting concluded with a financial and administrative overview from Cardiff University, aligning us on deliverables, timelines, and coordination for the months ahead.
Reflecting on our progress and looking ahead
Reflecting on our progress so far, our coordinator, Yacine Rezgui, highlighted the importance of close collaboration with our pilot cities:
"This year has been marked by constructive dialogue with our cities: Bratislava, Larissa, Odessa, and Thessaloniki, driven by a shared commitment to advancing more sustainable, inclusive, and antifragile mobility in complex urban systems. Together, we have taken meaningful steps toward understanding how cities can not only withstand disruption, but also learn, adapt, and grow stronger through informed short, and long-term change."
He also emphasised the significant progress we have already made, including on:
- Urban event mapping, establishing a structured approach to identifying, categorising, and analysing urban events and disturbances across environmental, social, economic, and infrastructural dimensions.
- Urban states of equilibrium, defining baseline urban conditions and dynamic equilibrium states against which disruption, adaptation, and transformation can be meaningfully assessed.
This General Assembly provided a great opportunity to align on key activities, strengthen collaboration across our team, and ensure a shared understanding of our work’s direction. We left Bratislava energised, connected, and ready for the next phase of AntifragiCity.
Thank you to all AntifragiCity partners, and to the Metropolitan Institute of Bratislava for hosting us at their new venue!

Establishing urban states of equilibrium for antifragile mobility
How do we measure whether urban mobility systems are moving towards antifragility? By establishing clear states of equilibrium.
Urban mobility systems are increasingly exposed to recurrent and compound disruptions that degrade performance and undermine equity. This deliverable develops a theoretical equilibrium framework for antifragile urban mobility, comprising two complementary components: a strategic Target-Setting Model that estimates a time-varying antifragility factor, and a three-layer operational equilibrium that couples traffic assignment and modal choice with infrastructure and service response.
The framework provides well-specified algorithms and assumptions to support sensitivity analysis and policy design for antifragile, equitable, and efficient urban mobility.
