4 Content of this presentation
> Approaches to create a data basis for modelling long-distance travel behaviour > U. Pfefferkorn > Content of this presentation What is long-distance travel? What data is available? What are approaches to capture long-distance travel? What is the „true“ annual trip frequency? How does the idea for the data fusion look like?

5 What is LDT? What data is available?
> Approaches to create a data basis for modelling long-distance travel behaviour > U. Pfefferkorn > What is LDT? What data is available? Different coverage of LDT segments: All segments in one data set (e. g. diary surveys, special long-distance surveys) Only certain segments: Certain purposes („business“, „holiday“, etc.) Duration (2+ days, 5+ days) Motivation (touristic travel and everyday travel) Two levels of data availability: Level of individual respondents = micro-level Level of aggregate figures the „common ground“: a certain distance LDT = Trips > 100 km

6 What is the „true“ annual trip frequency?
> Approaches to create a data basis for modelling long-distance travel behaviour > U. Pfefferkorn > What is the „true“ annual trip frequency?

7 What can be concluded from that?
> Approaches to create a data basis for modelling long-distance travel behaviour > U. Pfefferkorn > What can be concluded from that? Single data sets lead to lower trip frequencies than the approach of a combination of data sources The true value for the annual long-distance trip frequency almost certainly lies somewhere between 8 and 17 It is very likely that the value is higher than 12.9, when different data sources are taken into consideration The data basis of a long-distance travel model should consist of the information of different specialized surveys.

8 Generation of a micro data set

9 > Approaches to create a data basis for modelling long-distance travel behaviour > U. Pfefferkorn > Summary & Outlook The wide range for long-distance trip-frequencies reveals today’s huge uncertainties relating to the quantification of long-distance travel demand. Approaches which aim to capture long-distance travel in one survey are assumed to underrepresent long-distance travel demand The challenge will be to create a combined data set that is free of overlapping of the single travel segments to avoid overestimation of long-distance trip frequencies. In forthcoming work the methods of the single parts (data fusion, calibration, consolidation, and evaluation) will be concretised and applied.
