1. Willingness to recommend = f (Waiting time satisfaction, Travel
time satisfaction, Experience on board satisfaction, Cost of trip satisfaction,
Weekday, Less than 10 min, Work purpose, 2 to 4 days a
week,5 days a week or more, Actual waiting time).
The second part of the analysis attempts to better understand
the characteristics of users who intend to use the service in the
future in relation to their willingness to recommend the service
to others. Respondents who indicated that they are willing to use
the service forever, for a long time, or for four years or more are
grouped together and are considered to be long term users. Passengers
who indicated that they will use the service for less than four
years, until they get a car, or only as long as they need it were considered
as short term users who do not intend to continue using
the service in the future. This second phase of the paper uses
descriptive statistics as the data is derived from a survey question
that accepted a variety of response-types; for example, while some
respondents wrote comments such as ‘‘for a long time,” others simply
stated the expected number of years. Therefore, because the
question was open-ended it has been analyzed using a
descriptive-statistic approach.
