MOBIS is a joint project undertaken by the ETH Zurich, the University of Basel, and the Zurich University of Applied Sciences.

MOBIS is co-financed by the Swiss Agency for Innovation Promotion (Innosuisse) and the Federal Department for the Environment, Transport, Energy and Communications (DETEC).

MOBIS is a study within the scope of the Swiss Competence Centres for Energy Research (SCCER Mobility) and Energy, Society, and Transition (CREST).

The study aims at conducting surveys related to mobility and analysing mobility behaviour with methods at the frontier of scientific research, in order to inform policy with respect to optimising transport planning in urban areas.

Participation in MOBIS is by way of a written invitation to randomly selected inhabitants of Swiss urban agglomerations. The invitation is non-transferable and may not be shared with others. Participation in the smartphone study is based on additional inclusion criteria.

Click on www.mobis.info (or type the link into your internet browser). To begin the survey, enter your eight-digit participant identification number.

The MOBIS survey is available in English, German and French.

The online survey takes about 10 minutes. In the separate smartphone study, there are two additional surveys.

The participant identification number was sent to you in a personal letter. In case you cannot find it anymore, please contact us via email at: mobis@ethz.ch

Sure.

No. To participate in the smartphone study, you first have to fill out the survey. Thereafter you will be automatically forwarded to the registration for the smartphone study, if you fulfil the inclusion criteria.

To participate in the smartphone study, you need to fulfil the following requirements:

1. Receipt of the written invitation (including the eight-digit participant identification number)
2. 18-65 years old
3. Regular use of a car (at least two days a week)
4. Live in a metropolitan area in the German- or French-speaking part of Switzerland
5. Use of a smartphone that can install the tracking app
6. Be able to walk 200m without pain or any other discomfort
7. You must not work as a professional driver
8. Sign the consent form

• Fill out the online survey and registration
• Download and activate the app
• Read weekly emails on study progress
• Fill out a validation survey of your tracked routes
• Fill out a somewhat longer final survey

• Online survey and registration: approx. 15 min.
• Download and activate the app: approx. 5 min.
• Read weekly emails on study progress: approx. 10 x 5 min.
• Fill out a validation survey of your tracked routes: approx. 10 min.
• Final survey: approx. 30 min.

In sum, approximately 2 hours.

The smartphone study will take place over two months.

The participant identification number breaks the link between data and study participants. The researchers directly involved in the study can link participants to the identification number, however, this is not possible for third parties. This pseudonymisation makes it possible for the study to link responses from the surveys with the data from the smartphone tracking, which would not be possible with complete anonymisation.

Once you have downloaded and installed the app, you need to enter your participant identification number. Thereafter you do not need to do anything else. The app will automatically track your mobility in the background.

The app collects your mobility behaviour based on GPS tracks. These mobility data are used to analyse transport. These analyses allow for the identification key mobility indicators (e.g. mode choice). Further, trip purposes are derived based on multi-day travel patterns, and spatial analyses are conducted. For technical details, see our data privacy policy.

You will receive weekly summaries of your mobility, by transport mode. For more details about the email contents, see mobility indicators.

No. Unfortunately, we cannot offer any compensation for the short online survey.

Yes. For your complete participation you will receive CHF 100. Complete participation implies tracking of mobility during the full two months of the study duration and filling out both surveys (validation survey and final survey). You will have to provide details for the transfer of the compensation in the final survey.

• The data will be exclusively used for research purposes.
• The data will be archived according to data protection requirements and made available for future research projects.
• Results will be published in the aggregate, which guarantees anonymity.
