Determining the distance of trips is an important step for household surveys on everyday traffic on a reporting date. In the past, the length of the pathways travelled by the respondents was subsequently estimated. This results in uncertainties regarding the accuracy and reliability of the collected data. Since several years, it is possible to add additional length information to the data records by using geo-information systems (GIS).
The aim of the project is to give recommendations whether and under which circumstances it might be possible to avoid the estimation of distances by respondents in the future. At the same time, the study also helps to assess the future viability of traditional household surveys on mobility behaviour and to identify potential for methodological improvements.
Within the project, it should be investigated which variants, possibilities and limits for the import of length information from GIS applications exist. Furthermore, it must be checked whether and to what extent estimated and calculated length specifications differ, in which quality the information is available and how it relates to the "true value". Cost aspects and data protection issues should also be considered.
