Social factors in future travel
(2006)Arbeitsberichte Verkehrs- und RaumplanungThis paper sketches the interaction between social networks, activity spaces/markets and traffic growth. It argues that these linkages influence the adoption of intelligent transport systems, in particular with respect to management and control technologies.<br/>Qualitative models of personal activity spaces and commercial markets are developed. These suggest that any decoupling between economic and traffic growth will be difficult. They ...Working Paper -
Qualität des Verkehrsangebots
(2004)Arbeitsberichte Verkehrs- und RaumplanungDie Auswertungen der mittleren Geschwindigkeit des öffentlichen Verkehrsangebots im Kanton Zürich basieren auf einer systematischen Auswertung der Fahrplandaten samt Zu- und Ab-gangswege. Als Basis dient eine repräsentative Stichprobe von 2331 geokodierten Wegen aus dem Mikrozensus Verkehr 2000, die mit öffentlichen Verkehrsmitteln zurückgelegt wurden. Die gewählten Routen sind nicht bekannt und eine Angebotsmenge musste für die Auswertung ...Working Paper -
Does road investment produce accessibility gains at a constant rate?
(2004)Arbeitsberichte Verkehrs- und RaumplanungThis note comments on the general practise to use public road capital as a proxy for the service of the road system, as also employed in Shirley and Winston (2004). It shows that the required assumptions are violated in the Swiss case and in all likelihood in most other spatial contexts as well.<br/><br/>Die Literatur zur Schätzung der Produktivitätswirkung des Strassennetz verwendet den Kapitalstock im Strassennetz als Mass für die ...Working Paper -

The Role of Simulation Modelling in Transport Analysis and Planning
(1998)The objective of this paper is to review the use of simulation modelling techniques in transport studies. Simulation has been used extensively over the past 50 years both in the academic study of transport and in the practical fields of traffic engineering and transport planning. The first part of the paper will review these developments and identify a number distinct stages in the evolution of transport simulation methodology. We will ...Working Paper -
Data yield as a function of survey design
(1998)The travel survey designer has to balance the wish for a comprehensive set of data items with the willingness of respondents to participate in a survey of a given duration and complexity and if participating, the number of journeys, the respondents will describe. This interaction between work load, response and data yield has been the subject of only a few published studies in spite of ist fundamental importance (Axhausen et al., 1997; ...Working Paper -

Presenting and preserving travel data
(1997)The investment in travel data is substantial in terms of money, time and effort, but very often that investment is not fully utilized or even protected. This workshop will look at how to maximize the use of the data through: • dissemination via new media (i.e. www etc.) • improved data presentation • proper archiving and will suggest procedures and guidelines for these activities. The workshop will also identify future research needs.Working Paper -
