Pervasive data have become a key source of information for mobility and transportation analyses. However, as a secondary source, it has a different methodological origin than travel survey data, usually relying on unsupervised algorithms, and so it requires to be assessed as a dataset. This assessment is challenging, because, in general, there is not a benchmark dataset or a ground truth scenario available, as travel surveys only represent a partial view of the phenomenon and suffer from their own biases. For this critical task, which involves urban planners and data scientists, we study the design space of the visualization of cross-origin, multivariate flow datasets. For this purpose, we introduce the Modalflow system, which incorporates and adapts different visualization techniques in a notebook-like setting, presenting novel visual encodings and interactions for flows with modal partition into scatterplots, flow maps, origin-destination matrices, and ternary plots. Using this system, we extract general insights on visual analysis of pervasive and survey data for urban mobility and assess a mobile phone network dataset for one metropolitan area.

Educating students to understand the dynamics of complex systems and acting with responsibility and equality in their professional/private life is pivotal. Implementing social changes in higher engineering education institutions is a challenge. This work is grounded empirically in the tailored practices of the gender equality Change Lab embedded in the network of Mediterranean engineering schools, which is a collective organizational integrity. We used action research and practical learning in our methodology. Design principles are provided, and methodological setup is included. We advocate that in order to mainstream gender equality, develop structures, and overcome some of the known limitations, we need to have conceptual clarity, well-targeted interventions, reflexivity, and empirical evidence. Moving from separate bureaucratic centrally-managed higher education institutions to interconnected networks that can organize self-assembling collaboration in the form of labs, with mutually beneficial partnerships contemplating social innovations, can challenge the melting of the traditional boundaries towards inclusive education. This can be done amidst university reforms conducive to such a transformation. Particular attention is paid to the role of HORIZON 2020 Training Augmented Reality Generalised Environment Toolkit (TARGET) project in conceptualizing gender equality learning and system change in Mediterranean engineering schools.
