Schlussbericht an das BABS, Bern. Zürich: IVT, ETH Zürich.  PDF Mittels eines agenten-basierten Simulationsmodells wurden die zu erwartenden Evakuationszeiten im Falle einer grossräumigen Evakuierung in Abhängigkeit verschiedener Faktoren wie Uhrzeit, Strassenverhältnissen und Grösse des evakuierten Gebietes bestimmt. Grundlage der Verhaltensmodellierung bildeten eine ausführliche Literaturrecherche, Experteninterviews sowie eine Befragung der Schweizer More

PNAS. Mehr With the help of travel smart card data, we uncover daily face-to-face encounter mechanisms and structures by constructing a time-resolved in-vehicle social encounter network on public buses. We find individuals with repeated encounters are not grouped into small communities. A large, imperceptible, small-world contact network is More

Paper presented at the 13th Swiss Transport Research Conference, Ascona, April 2013.  Mehr In this paper, we present a framework of a decision support system designed to analyse information provided by agent-based transport demand models, travel diary surveys and automatically collected data on transport infrastructure usage. The practical More

In: disP, 48 (3) S.40-53.  Mehr Respondents to a stated adaptation survey were faced with scenarios in which their travel conditions were changed, and asked how the implied changes would affect their activity scheduling. The data was used to estimate models of adaptations, which yielded sparse reactions despite More

Transportation Research Record.  Mehr In the transport modelling community, there is a growing consensus that attitudes of travellers have to be taken into account. Though it is not possible to measure attitudes directly, psychometric scales can be used as indicators. The paper presents psychometric scales for environmentalism and More

In: Transportation Research A.  PDF This paper combines a macroscopic modeling of traffic congestion in urban networks with an agent-based simulator to study congestion pricing. Results show that by applying this kind of congestion pricing, the travel time saved outweighs the cost. In addition, the congestion inside cordon More

Paper to be presented at the 91th Annual Meeting of the Transportation Research Board, Washington, D.C.. January 2012.  Mehr The paper elaborates on shape grammars, which describe in the form of rules how transport network elements are added to each other for network design. The impact of shape More

Research Board. Washington, DC, January 2012.  PDF A recent study aimed to estimate the potential of carpooling in Switzerland. Part of this study was a survey in which the attitude of the public towards this transport option was investigated using both multi-response questions and stated preference experiments.

Paper presented at 51th ERSA Conference, Barcelona, September 2011.  PDF The paper describes the implementation work for a parcel based land use transport interaction model in the canton Zurich. The focus is on the challenges and solutions regarding data acquisition and preparation, which is an important issue regarding More

BMC Infectious Diseases, 11, 115.  PDF Wie kann man (Grippe)epidemien räumlich und zeitlich detailliert modellieren, wenn räumlich hoch aufgelöste Daten zum Verkehrsverhalten zur Verfügung stehen? Auf Grundlage der MATSim-Ergebnisse wurde die Wahrscheinlichkeit berechnet, wie häufig sich Personen von Tag zu Tag treffen. Die Übereinstimmung der Modellergebnisse mit der More

Paper presented at the 90th Annual Meeting of the Transportation Research Board. Washington, D.C. Mehr This paper introduces a new approach for the generation of activity plans for microscopic transport simulations. It plans activities based on the expected development of need levels of the modeled people. The procedure More

Forschungsbericht, vdf Hochschulverlag AG, Zürich.  Mehr Im Fokus der Arbeiten liegt zum einen die Analyse der sich aus dem Ausbau der Verkehrssysteme ergebenden Erreichbarkeitsverbesserungen von Tourismusorten und alpinen Regionen über die letzten fünf Jahrzehnte, zum anderen die Reisezielwahl der Touristen sowie deren Ansprüche an die Verkehrsinfrastruktur und die More

Zürich: Arbeitsberichte Verkehrs- und Raumplanung, 640, IVT, ETH Zürich.  Mehr This paper describes the concept of a versatile transport simulation framework to be used for the development of integrated transport simulation models. The idea of the presented framework is to handle the complexity of modularized and parallelized software More

Paper presented at the 89th Annual Meeting of the Transportation Research Board, Washington, D.C., January 2010.  PDF This paper presents an algorithm for route set generations. It is based on shortest path search with link elimination. A Breadth First Search is combined with a topologically equivalent network reduction More

Endbericht, F&E Förderung: Science to Market, KTI 8443.1 ESPP-ES, Datapuls AG. Zürich: IVT, ETH Zürich.  PDF Mobilität bildet den Grundpfeiler, auf dem ortsbasierte Dienstleistungen (Location Based Services) ruhen. Mikrosimulationsmodelle zur Generierung von Moblität liefern hierzu eine vollständige Mobilitätsanalyse. Basierend auf dem Open-Source Forschungsprojekt MATSim ist dafür das erste, More

In: Research in Transportation Economics, 25, 8-18.  Mehr While previous studies have focused on specific and localised changes, the research described in this paper deals with the aggregate effects of changed generalised costs of travel on traffic generation. The generalised cost and accessibility elasticities estimated with a structural More

Paper presented at «Applications of Social Network Analysis» (ASNA), Zürich, September 2009. PDF Es wird über eine Befragung im Rahmen eines Projektes berichtet, in dem Informationen über die räumliche Verteilung sozialer Netzwerke und Freizeitaktivitäten gewonnen werden sollen. Um möglichst zusammenhängende persönliche Netzwerke zu erheben wird eine aufsteigende Stichprobentechnik verwendet, More
