Multivariate time series forecasting for freeway networks

This dissertation introduces traffic forecasting methods for different network configurations and data availability.Chapter 2 focuses on single freeway cases.Although its topology is simple, the non-linearity of traffic features makes this prediction still ...

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 ...

Model-based Identification, Estimation, and Control for Large-scale Urban Road Networks

Nikolaos Geroliminis, Isik Ilber Sirmatel

Network-level road traffic control remains a challenging problem. Macroscopic fundamental diagram (MFD) based dynamical models of large-scale urban networks enable development of model predictive perimeter control methods, which represent an efficient cong ...

Virtual Traffic Lights: System Design and Implementation

Aurélien Pomini, Sami Ben Hassen, Frank Schmutz

Traffic congestion is a daunting problem that is affecting the daily lives of billions of people across the world. Recently, a promising new traffic control scheme known as Virtual Traffic Lights (VTL) has been proposed for mitigating traffic congestion. V ...

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 ...

An Integrated Assessment Method for Sustainable Transport System Planning in a Middle Sized German City

Julia Schmale

Despite climate change mitigation and sustainability agendas, road transport systems in Germany and the resulting environmental burden are growing. Road transport is a significant source of emissions in urban areas and the infrastructure has a significant ...

Effects of hard shoulder lanes configuration on driver’s behaviour

André-Gilles Dumont, Jade Chapoton

Nowadays, reassignments of hard shoulders into traffic lanes are spreading across Europe. This traffic management measure allows to respond to the growing saturation of high-capacity roads.In Switzerland, the first stretch to be equipped in such a way was ...

Assessment of Dynamic Speed Limits on freeway A20 near Rotterdam, The Netherlands

On Freeway A20 near Rotterdam, Netherlands, a trial with dynamic speed limits began on June 28, 2011. On a 4.2-km stretch, the speed limit increased from 80 to 100 km/h as soon as congestion appeared to set in and at night. The aim of dynamic speed limits ...

An aggregate model for transient and multi-directional pedestrian flows in public walking areas

Michel Bierlaire, Bilal Farooq, Flurin Silvan Hänseler

A dynamic pedestrian propagation model applicable to congested and multi-directional flows is proposed. Based on the cell transmission model, several important extensions are made to describe the simultaneous and potentially conflicting propagation of mult ...
