Dataset: Modelling human activities in a system of cities

This repository contains the input data for the paper 'Modelling human activities in a system of cities'. The input data is used to run the DAVE model for Cantons Vaud and Geneva in Switzerland at 500m grid. DAVE (Dynamic Anthropogenic actiVities and feedback to Emissions) is a multi-scale agent-based modelling system. It uses a bottom-up approach to model the interactions and feedback between urban form (e.g., building morphology, materials), urban function determined by human activities

La « locomotive à fumée ». Histoire de la pollution de l'air par le chemin de fer au temps de la vapeur (France, Grande-Bretagne, années 1820-1960)

This thesis reinterprets the history of railways and steam traction through the lens of air pollution between the 1820s and 1960s, using a comparative approach between France and Great Britain. By shifting the focus from steam to smoke, it not only provides a new example of the social and environmental damages caused by industrialization in the 19th and 20th centuries, but also demonstrates how air pollution can influence the development of a technical system. Drawing on the sensitivities expressed by local

Modelling the coevolution of London's population and railway system

As cities continue to expand it has become crucial to describe their evolution in time and space. Building on analogies with biological systems, we propose a minimalist reaction-diffusion model coupled with economic constraints and an adaptive transport network, describing the co-evolution of population density with the transport system. Using a unique dataset, we reconstruct the evolution of London (UK) over 180 years and show that after an initial phase of diffusion limited growth, population has become l

Network design of a transport system based on accelerating moving walkways

Michel Bierlaire

Pollution, congestion and urbanistic considerations are leading to a change in the use of private vehicles in dense city centers. More frequently, the last-mile is covered with systems such as public transport, car sharing and bike sharing as well as an increase in walking and cycling. Following this trend, we assume a hypothetical scenario where the use of private cars is strongly limited in dense urban areas, and innovative transport modes must be used. This work investigates a futuristic system based on

An exploration of moving walkways as a transport system in urban centers

Michel Bierlaire

Moving walkways (MW) have been imagined as a possible means of transport since the late 19th century, and this system has fascinated urban planners and engineers ever since. Contrary to what has been imagined, moving walkways are only used in transportation hub corridors, and not as a main transport mode in city centers. Today however, MWs are receiving increasing attention as a possible solution to congestion and pollution, as well as a catalyst for soft mobility. This paper explores the role of moving wal

Transport mode choice in alpine resorts in Switzerland

Vincent Kaufmann

Mountain regions are under-represented in transport research, which tends to concentrate on urban areas. This study investigates transport mode choice in 22 locations in the Alps, using data from the 2010 Swiss transport micro-survey (hereafter: MRMT2010) which has detailed information from 68'868 people in a representative national sample who describe their transport behaviour on a reference day. The Swiss Statistical Office subdivides the territory of Switzerland into city centres, suburbs, outer suburbs,

Superdiffusive transport in laboratory and astrophysical plasmas

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Kyle Gustafson, Alexandre Dominique Bovet

In the last few years it has been demonstrated, both by data analysis and by numerical simulations, that the transport of energetic particles in the presence of magnetic turbulence can be superdiffusive rather than normal diffusive (Gaussian). The term ‘su ...

Turbulence and zonal flow structures in the core and L-mode pedestal of tokamak plasmas

Olivier Sauter, Laurent Villard, Stephan Brunner, Trach-Minh Tran, Ben McMillan, Gabriele Merlo, Julien Stanislas Pierre Dominski

Zonal flows (ZF) play a crucial role in regulating ion temperature gradient (ITG) turbulence. In previous global gyrokinetic simulations [1] using the ORB5 code with the adiabatic electron model, it was observed that long-lived ZF structures, leading to a ...

Setting the Scene: Background and Overview of Regulatory Reform in the Transport Sector

This book concerns the regulation of transport within a European context, covering air, inland waterways, rail, road passenger and freight, urban public transport, and short sea shipping. All these sectors have experienced substantial changes over the past two decades, in terms of ownership, competition and liberalization, and the book explores the main transformations and their impacts. The authors address these issues, with a specific focus on the effects of the organization and regulation of transport sy

Herbicides export dynamics of a mid-sized lake tributary: lessons from observations and modelling

Bettina Schaefli

We present here a model which couples the hydrologic component and the transport of herbicides within a catchment. The model used takes into account the age structure of the stream water in order to characterize short and long term fluctuations of herbicide flux concentrations. The highly dynamic behavior of herbicides concentrations may lead to the exceedance of specific toxic threshold and is therefore key to exposure risk assessment of aquatic ecosystems. The model is based on a travel time formulation o

Modelling migration and dissolution of mineral particles in saturated porous media

Christof Holliger

Understanding and predicting the fate in soils and other porous media of solid mineral particles with grain diameters in the micrometer range is important in a number of environmental and civil engineering applications, including subsurface hydrology, wastewater treatment and oil/gas production. In this context, deep-bed filtration theory is commonly applied to model particle detachment and deposition. Most existing models however neglect some processes that can modify groundwater flow patterns, particle co

Mobility and social exclusion : the need of a comprehensive research approach

In recent years, issues of social inequality and social exclusion in mobility and transport have gained increasing attention, both in empirical research and in policymaking and transport development. While some European countries (such as Great Britain, the Netherlands, France and Switzerland) can be seen as outstanding examples in this context, gaps within research and between research findings and political action persist. While researchers have called for more attention to the mobility of individuals and

How to cope with the planning process of public transport in Latin American cities?

Planning and designing an efficient public transport system represents an important but difficult challenge for public authorities. Frequently, the lack of coordination between different public and private stakeholders involved affect serious obstacles. Considering related problems experienced in the city Santiago de Chile, this paper suggests a comprehensive planning approach that integrates diverging interests, such as engineering and social sciences. Accepting the important role of existing planning tool

Analyse de l’intermodalité fret en Suisse

Cet article fournit une analyse du transport intermodal en Suisse. Il fait partie de la série d’expertises indépendantes effectuées pour l’Observatoire des Politiques et Stratégies de Transport en Europe. La principale composante du trafic intermodal en Suisse est le transit international (90%), où le trajet Nord-Sud domine nettement. Ce transit est réparti en parts relativement égales entre le transport routier, le combiné rail-route (dont l’autoroute roulante, qui ne représente que 4% du transit) et le fe

Export of Pollution from Europe: Seasonal and Interannual Variation

Pollution can undergo long-range transport and impact the tropospheric chemistry thousands of kilometers downwind from the source region. Recently, there is interest in the intercontinental transport (ICT) of pollution between the main industrial regions of the extratropics of the Northern Hemisphere, especially the contribution of foreign pollution to regional episodes of high ozone. We present the results of a modelling investigation of the seasonal and interannual variations in the ICT of pollution from

The role of clustering effects in interpreting nondiffusive transport measurements in tokamaks

Recent measurements in tokamak plasmas provide clear evidence for rapid nondiffusive transport and non-Gaussian fluctuations, and have been widely interpreted in terms of the sandpile and self-organized criticality (SOC) paradigms. Many of the statistical physics inferences that can be drawn from observations of, for example, avalanching transport remain to be explored. This paper will show that the statistical characterization of both experimentally observed and simulated avalanching transport phenomena re

Integrated electromagnetic levitation and guidance system for SwissMetro project

Alfred Rufer

Electromagnetic levitated and guided systems are commonly used in the field of people transport vehicles, tool machines, frictionless bearings and conveyor systems. In the case of low speed people transport vehicles, the electromagnetic levitation offers the advantage of a very silent motion and of a reduced maintenance of the rail. In the world there are actually two working low speed systems: the japanese HSST ( [1], [2] ) and the english BAMS ( Birmigham Airport MagLev System [3] ). In both these magneti

A probabilistic model for ligand-cytoskeleton transmembrane adhesion: predicting the behavior of microspheres on the surface of migrating cells

Jean-Jacques Meister

A theoretical model describing the attachment and cytoskeletal coupling of microspheres to the dorsal surface of motile cells was developed. Integral membrane receptors beneath a ligand-coated microsphere are allowed to be either free, attached to the microsphere, bound to the rearward moving actin network, or linked to both the bead and the cytoskeleton, and to switch between these four states. The binding transitions being modeled as chemical reactions governed by rate constants taken from literature, the
