The German Mobility Panel survey consists of two parts: the everyday mobility survey and the car mileage and fuel consumption survey.
Every year in autumn, households and people are surveyed on their everyday mobility. Participants are asked to provide general information such as public transport accessibility, car ownership or information about the household members. In addition, each person over 10 years of age is asked to fill in a trip diary with all trips made in the course of one week, including start and end time of each trip, means of transport used, trip purpose (work, shopping, etc.) and distance covered. This part of the survey can be filled in online or in a paper questionnaire.
Households with car ownership are also asked about mileage and refuelling events of their cars. The duration of this part of the survey is 8 weeks and it takes place in spring. Household members are asked to fill in a odometer reading and car mileage diary for each household vehicle, reporting on all refuelling events including the date the refuelling event took place, current mileage, amount of gasoline dispensed and refuelling cost. Participants also provide information on each household vehicle (year, fuel type, power, etc.).
Households receive addressed prepaid envelopes for all the documents (no need to add postage). For participating in the survey every household is given a little reward.
