Mobile phone data collected by network operators can provide fundamental insights into individual and aggregate mobility of people, at unprecedented spatiotemporal scales. However, traditional call detail records (CDR) have fundamental issues because of low accuracy in both spatial and temporal dimensions, which limits their applicability for detai...
This work investigates network-related trajectory features to unravel trips that the most contribute to the system under-performance. When such trips are identified, features analysis also permits to identify the best alternatives i terms of routes to make the system to its optimum. First, data mining is carried out on trajectories obtained from re...

We study numerically the pair trajectories of rigid circular particles in a two dimensional inertialess simple shear flow of a (Binghamian) yield stress fluid. We use a Lagrange multiplier based fictitious domain method, following Glowinski et al. [26, 28, 29], for solving the problem. Contacts between the particles at a finite interparticle distan...

The purpose of this study is to compare optimal network loadings related to network equilibria. The direct comparison of path flows or trajectory patterns is hard to achieve so here we propose a more aggregate approach based on the comparison of demand level breakpoints. A breakpoint occurs at a particular demand level when after this level, the pa...
PROSPECT aims at developing a new generation of proactive safety systems to protect Vulnerable Road Users (VRUs), with an emphasis on pedestrians and cyclists. To improve sensor effectiveness, PROSPECT will expand the scope of scenarios addressed by sensors already on the market, enhancing their overall performance. Interactions between vehicles an...

RésuméL'offre d'outils numériques proposée aux agriculteurs ne cesse d'augmenter, laissant augurer des gains considérables. Mais qu'en est-il dans les faits ? Pourquoi et pour quels usages les agriculteurs adoptent-ils ces nouvelles technologies ? Quels en sont les effets sur le travail ? À partir de deux études de cas, cet article montre que la mo...
