Hierarchical Management of Heterogeneous Large-Scale Urban Networks via Path Assignment and Regional Route Guidance

Nikolaos Geroliminis, Isik Ilber Sirmatel, Mehmet Yildirimoglu

High level of detail renders microscopic traffic models impractical for control purposes and local control schemes cannot coordinate actions over the whole city. Thus, development of efficient modeling and control methods for large-scale urban road network ...

Accounting for Dynamics in Pedestrian multi-class speed-density relationship

Marc-Edouard Baptiste Grégoire Schultheiss

In this project, we propose a probabilistic modeling approach to represent the speed- density relationship of pedestrian traffic. The approach is data-driven and is motivated by the presence of high scatter in the raw data I have been provided with (tracki ...

Data-driven spatio-temporal discretization for pedestrian flow characterization

Michel Bierlaire, Marija Nikolic

We propose a novel approach to pedestrian flow characterization. The definitions of density, flow and velocity existing in the literature are extended through a data-driven spatio-temporal discretization framework. The framework is based on three-dimension ...

Multi-class speed-density relationship for pedestrian traffic

Michel Bierlaire, Matthieu Marie Cochon de Lapparent, Marija Nikolic, Riccardo Scarinci

We introduce a modeling approach for pedestrian speed-density relationship. It is motivated by a high scatter in real data that precludes the use of traditional equilibrium relationships. To characterize the observed pattern we relax the homogeneity assump ...

Pedestrian management strategies for improving flow dynamics in transportation hubs

Michel Bierlaire, Riccardo Scarinci, Nicholas Alan Molyneaux

Forecasts predict a strong increase of the demand of public transport facilities in the next decades, close to doubling the number of users in the "Arc lémanique" area. This increase in demand can lead to congestion and poor level-of-service inside transpo ...

A Reaction-Diffusion Model for Congestion Propagation in Urban Networks

Nikolaos Geroliminis, Leonardo Bellocchi

While cascade phenomena have been broadly studied by physicists, understanding and modeling of congestion propagation in large urban city networks still remains a challenge. Most efforts are mainly based on micro-simulations of link-level traffic dynamics ...

DYNAMIC CLUSTERING AND PROPAGATION OF CONGESTION IN LARGE TRAFFIC NETWORKS

Nikolaos Geroliminis, Mohammadreza Saeedmanesh

The problem of clustering in urban traffic networks has been mainly studied in static framework by only considering traffic conditions at a given time. Nevertheless, it is important to underline here that traffic is a strongly time-variant process and it n ...

Dynamic clustering and propagation of congestion in heterogeneously congested urban traffic networks

Nikolaos Geroliminis, Mohammadreza Saeedmanesh

The problem of clustering in urban traffic networks has been mainly studied in static framework by considering traffic conditions at a given time. Nevertheless, it is important to underline that traffic is a strongly time-variant process and it needs to be ...
