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 -

Activity Patterns in Three Industrialized Countries
(1994)This paper will compare the activity patterns of three post-industrial countries: Germany, Great Britain and United States of America. It will give special emphasis on the discussion and assessment of the relationship between activity patterns and mode choice. The data sources used are a set of three household based travel diaries reported by large nationwide samples. Work day activity and mode chains will be separated in two different ...Working Paper -
The simple exponential smoothing learning model
(1994)There is an increasing interest in transport in modelling the dynamics of repeated choices, especially in the context of route and departure time choice. Those models adopting microscopic simulation require an assumption about the learning behaviour of the drivers, i.e. about the mechanism which integrates the information obtained from the most recent choice into the expectations of the drivers, which in turn form the basis of the next ...Working Paper
