Going Nowhere fast: the illusion of speed and the depletion of proximity

Dr. Cecília Silva is Assistant Professor with habilitation at the Faculty of Engineering, University of Porto (FEUP), and senior researcher at CITTA – the Research Centre for Territory, Transports and Environment. She is a Civil Engineer with specialization in Spatial Planning and Urban Mobility. Her main research fields include Accessibility Planning, Sustainable Mobility, Mobility Management, and Planning Support Instruments; research developed in close connection to local planning practice. She is mainly interested in integrated land use and transport policies for human-scale cities. More information about her is at

Modelling urban economic segregation: a theoretical and quantitative quest for causal processes and their interactions across scales

Dr. Clémentine Cottineau is a quantitative urban geographer, currently Assistant Professor of urban studies at TU-Delft. Her main area of research revolves around modelling the evolution of economic segregation and inequality between and within cities, using systematic literature reviews, longitudinal analysis of empirical microdata and generative agent-based modelling. She holds a PhD in Geography from Université Paris 1 Panthéon-Sorbonne. During previous research positions at UCL’s Centre for Advanced Spatial Analysis and CNRS’s Centre Maurice Halbwachs between 2014 and 2020, Clémentine has worked on the patterns and regularities of urban scaling laws, shrinking cities and industrial geographies.

Everyday geographies, neighbourhood effects and urban segregation

Dr. Julie Vallée is a social geographer working in the Géographie-cités laboratory in France and holding a senior research position at the National Centre for Scientific Research (CNRS). For the past 15 years, Julie has been using quantitative methods to explore and interconnect people's daily mobility, urban segregation, neighbourhood effects and social inequalities, especially in health. She is the scientific leader of Mobiliscope, an open tool available for a large number of city regions in France, Canada and Latin America and displaying interactive maps and graphs to explore how cities, neighbourhoods and social segregation change around the clock.

Digital Planning: a usability challenge

Prof. Dr. Stan Geertman is emeritus Professor of Urban and Regional Planning at Utrecht University in the Netherlands. He has published widely in scientific and practice-oriented journals and has published a range of (editorial) books. He is member of the editorial board of several scientific journals (e.g., CEUS). He has been member of a range of international conference organizations (EGIS; JECC; AGILE; DDSS) and was chair of the Board of Directors of CUPUM (Computational Urban Planning and Urban Management) during past 10 years. His research interests include Planning and Decision Support Systems (PSS / DSS), Digital Planning, Sustainable Urbanization, and Planning Theory and its implications for practice.
