Controlling pedestrian flows with moving walkways

Michel Bierlaire, Nicholas Alan Molyneaux

Moving walkways are pedestrian dedicated hardware which generally decrease pedestrian travel time. We propose the utilization of these devices to dynamically control pedestrian flows in order to improve pedestrian dynamics. Three variations of a control st ...

Two-layer hierarchical control for large-scale urban traffic networks

Nikolaos Geroliminis, Anastasios Kouvelas

Many efforts have been carried out to optimize the traffic signal settings in cities. Nevertheless, state-of-the-art and -practice strategies cannot deal efficiently with oversaturated conditions (i.e. queue spillbacks and partial gridlocks), as they are e ...

A dynamic network loading model for anisotropic and congested pedestrian flows

Michel Bierlaire, Marija Nikolic, Flurin Silvan Hänseler, Gael Lederrey

A macroscopic loading model for multi-directional, time-varying and congested pedestrian flows is proposed. Walkable space is represented by a network of streams that are each associated with an area in which they interact. To describe this interaction, a ...

Taste heterogeneity and latent preferences in the choice behaviour of freight transport operators

Michel Bierlaire

In this paper we show that individual attitudes of road carriers and their latent preferences toward specific freight service attributes do play a role in determining their mode choices. Specifically, we contribute to the empirical literature on freight ag ...
