Probabilistic speed-density relationship for pedestrian traffic: a data-driven approach

Michel Bierlaire, Bilal Farooq, Marija Nikolic

We propose a probabilistic modeling approach to represent the speed-density relationship of pedestrian traffic. The approach is data-driven, and it is motivated by the presence of high scatter in the raw data that we have analyzed. We show the validity of ...

Modeling pedestrian flows in train stations: The example of Lausanne railway station

Michel Bierlaire, Michaël Clément Louis Ghislain Thémans, Riccardo Scarinci, Flurin Silvan Hänseler, Nicholas Alan Molyneaux

In collaboration with the Swiss Federal Railways (SBB-CFF-FFS), various challenges associated with pedestrian flows in train stations are discussed at the example of Lausanne railway station. For this site, a rich set of data sources including travel surve ...

Activity choice modeling for pedestrian facilities

Antonin Danalet

This thesis develops models of activity and destination choices in pedestrian facilities from WiFi traces. We adapt the activity-based travel demand analysis of urban mobility to pedestrians and to digital footprints. We are interested in understanding the ...

A macroscopic loading model for dynamic, anisotropic and congested pedestrian flows: Implementation, calibration and case study analysis

Gael Lederrey

Pedestrian facilities are more and more congested. It is important to understand the modeling of pedestrian flows to assure safety and comfort. Many models have already been developed such as the social force modle and PedCTM. The problem is that either th ...

The activity path approach to activity pattern modeling

Michel Bierlaire, Antonin Danalet

In this presentation, we propose a model for the simultaneous choice of activity types, order, start times and durations of activity episodes in a sequence. In particular, we develop a framework for choice set generation based on path choice to deal with t ...

Importance sampling for activity path choice

Michel Bierlaire, Antonin Danalet

We propose a model for the choice of an activity pattern. Models of activity participation patterns allow to assess the impact of demand management strategies on activity and destination choices. In particular, we focus on choice set generation of activity ...

A Bayesian Approach to Detect Pedestrian Destination-Sequences from WiFi Signatures

Michel Bierlaire, Bilal Farooq, Antonin Danalet

In this paper, we propose a methodology to use the communication network infrastructure, in particular WiFi traces, to detect the sequence of activity episodes visited by pedestrians. Due to the poor quality of WiFi localization, a probabilistic method is ...

Activity pattern modeling: A path choice approach

Michel Bierlaire, Antonin Danalet

In Switzerland, the largest railway stations are called "RailCities" by the Swiss Railways. It emphasizes their transformation into place to live and perform several different activities, similar to a small-scale city. Similar concerns than in urban areas ...

A path choice approach to activity modeling with a pedestrian case study

Michel Bierlaire, Antonin Danalet

In Switzerland, the largest railway stations are called RailCities by the Swiss Railways. It emphasizes their transformation into places to perform different activities, similar to a small-scale city. Concerns are similar than in urban areas: costs of new ...
