Linking trajectory data collected with a swarm of drones to the underlying urban network for macroscopic traffic parameter estimation

Nikolaos Geroliminis, Emmanouil Barmpounakis

Recently, an open-data initiative was announced with one of the most complete datasets to study urban congestion. The pNEUMA dataset consists of more than half a million trajectories in heterogeneous traffic. In order to utilize the dataset for macroscopic ...

A complex networks approach to traffic flow theory: measures and models

Leonardo Bellocchi

In this thesis, we developed a research direction that combines the theoretical concepts of complex networks with practical needs and applications in the field of transportation engineering. As a first objective we analyzed the phenomenon of congestion pr ...

Measurement, Data Interpretation, and Uncertainty Propagation for Fatigue Assessments of Structures

Ian Smith, Alain Nussbaumer, James-Alexandre Goulet, Romain Pasquier, Claire Acevedo, Luca D'Angelo

Real behavior of existing structures is usually associated with large uncertainty that is often covered by the use of conservative models and code practices for the evaluation of remaining fatigue lives. In order to make better decisions related to retrofi ...

Temporal evolution of crack propagation propensity in snow in relation to slab and weak layer properties

Johan Alexandre Philippe Gaume, Jürg Schweizer, Alec van Herwijnen

If a weak snow layer below a cohesive slab is present in the snow cover, unstable snow conditions can prevail for days or even weeks. We monitored the temporal evolution of a weak layer of faceted crystals as well as the overlaying slab layers at the locat ...

Asphalt Mixture with RAP: Mix Design Optimization

André-Gilles Dumont, Nicolas Bueche, Michel Pittet, Sara Bressi

The addition of reclaimed asphalt pavement (RAP) in hot mix asphalt is now common practice in Switzerland. With the increases of RAP content in asphalt mixture, the problematic of the mix design optimization becomes an important issue to be considered. The ...

Assessing the usage and level-of-service of pedestrian facilities in train stations: A Swiss case study

Michel Bierlaire, Riccardo Scarinci, Flurin Silvan Hänseler

A framework for assessing the usage and level-of-service of rail access facilities is presented. It consists of two parts. A dynamic demand estimator allows to obtain time-dependent pedestrian origin-destination demand within walking facilities. Using that ...

The Impact of Road Ecosystem upon Soils’ Qualities and Functions: Preliminary Observations on the French Normative Framework of Road Design

Antoine Vialle

This presentation seeks to investigate the processes through which modern roads are conceived and realized. This approach can not only contribute to identify some of the main spatial characteristics of the non-dense urban territories, but also enables to u ...
