Monitoring the effects of tariff raises in public transport within the framework of the general mobility developments. This description comprises the eight wave of the longitudinal mobility survey ( longitudinaal verplaatsingsonderzoek ). Subsequent waves will be stored under different study numbers. The survey monitors ( changes in ) transportational behaviour, mobility and effects of raising tariffs for public transportation. Data were gathered by telephone and mail- questionnaire. Diaries, describing all mobility during one week, and personal questionnaires were not used this wave. Like wave 4 this wave is mainly administrative to keep the panel alive and check changes in its composition. Some extra questions were asked regarding opinions on public transport and costs of car-use.
