acceleration measurements:
Sorted in subfolders labelled with the surface type. File format: .csv (comma separated values)

first column: "time" - timestamp with date and time - dd.mm.yyyy hh:mm
second column: "x" - acceleration in direction of x-axis in m/s using dots (.) as decimal separator
third column: "y" - acceleration in direction of y-axis in m/s using dots (.) as decimal separator
fourth column: "z" - acceleration in direction of z-axis in m/s using dots (.) as decimal separator



speed measurements:
One single Windows Excel file with one spreadsheet per surface type. File format: .xlsx

first column: e.g. "Mariahilfer Strae
 4811'49.1""N 1620'42.7""E" - name of measurement position with latitude and longitude coordinates
second column: "headwind" - Yes (Y) if the rider was moving against the wind; otherwise No (N)
third column: "riding velocity v" - measured velocity in km/h using comma (,) as decimal separator
fourth column: "wind velocity v_w" - measured in m/s using comma (,) as decimal separator
fifth column: "headwind velocity" - wind velocity with proper sign, depending on the content of the second column (headwind yes or no) in km/h using comma (,) as decimal separator



survey:
Contains one .pdf file with the survey questions in German, one .csv and one .xlsx file with survey results (output from www.umfrageonline.com). The .csv and the .xlsx file contain the same information.

first column: "_Anwort-ID" - internal ID used by www.umfrageonline.com
second column: "Resume-Code" - internal ID used by www.umfrageonline.com
third column: "Start" - Starting time for each individual participant
fourth column: "Datum und Zeit" - date and time
fifth column: "Teilnahmestatus" - participation status with possible status being the following: participated and finished; participated, but not finished
starting from the sixth column: survey questions (numbered) with answers below in rows or following in the column(s) next to the question (not numbered), depending on the question type.
