Best-worst stated preference survey on Park&Ride facility choice

The files here are asscoiated with the following paper:
Geržinič, N., van Cranenburgh, S., Cats, O., Lancsar, E., Chorus, C.G. (2021). Estimating decision rule differences between ‘best’ and ‘worst’ choices in a sequential best worst discrete choice experiment. Journal of Choice Modelling, Volume 41. https://doi.org/10.1016/j.jocm.2021.100307.

The two datasets contain the survey responses and the experimental design of the stated choice experiment. In the experiment, respondents had to alternatingly select the best, then worst, then best, then worst alternative of the remaining options. The alternative that was selected was removed and the remaining ones left on screen, until an implict order of all 5 alternative is obtained. A total of 12 choice situations are analysed, for which 108 fully valid responses are recorded.


Each alternative is described with five attributes:
- Travel time by car [from home to the Park&Ride facility]
- Travel time by public transport [from the Park&Ride facility to work/school]
- Price [parking for one day, include a return public transport trip]
- Mode of public transport [bus or train]
- Public transport headway [how frequently the line operates]


The dataset "survey_design" contains the attribute levels for each alternative in each choice set.
- Choice situation       -->  Running order of the choice situations, as experienced by respondents
- Number in each column  -->  Alternative number (between 1 and 5)
- Car                    -->  Travel time by car
- PT                     -->  Travel time by public transport
- C                      -->  Parking and ticket cost
- Mode                   -->  Mode of public transport [0=bus, 1=train]
- H                      -->  Public transport headway


The dataset "raw_data" contains the survey responses. 
- Sx                 -->  Choice situation x 
- Cy                 -->  Consecutive choice y (1,3=best; 2,4=worst) made by the respondent in choice set x
- R1-5               -->  Answers to the 5 regret scale statements (1=fully disagree, 7=fully agree)
- Gender             -->  1=female, 0=male
- Age                -->  open question
- Education          -->  1=elemntary, 2=middle/vocational, 3=high school, 4=bachelor, 5=master, 6=PhD
- Employment         -->  1=student, 2=employed full time, 3=employed part time, 4=working from home, 5=unemployed, 6=retired, 7=other
- Income             -->  1=below 500€, 2=500-1.000€, 3=1.000-1.500€, 4=1.500-2.000€, 5=2.000-3.000€, 6=3.000-4.000€, 7=4.000-6.000€, 8=6.000-10.000€, 9=above 10.000€, 10=do not wish to say
- Cars               -->  0=0, 1=1, 2=2, 3=3 or more
- License            -->  0=no, 1=yes
- Household          -->  1=1, 2=2, 3=3, 4=4, 5=5 or more
- P&R experience     -->  0=no, 1=yes
- Travel frequencey  -->  1=daily, 2=weekly, 3=more than monthly, 4=monthly, 5=less than monthly, 6=a few times per year, 7=once per year or less
- Mode to LJ         -->  1=car driver, 2=car passenger, 3=P&R, 4=city bus, 5=regional bus, 6=train, 7=bike, 8=walk, 9=other
- Mode in LJ	     -->  1=car driver, 2=car passenger, 3=P&R, 4=city bus, 5=regional bus, 6=train, 7=bike, 8=walk, 9=other
