Objectives of the survey

The City of Flensburg has commissioned the Dortmund planning office Planersocietät to conduct the mobility survey. The survey will be used to deduce figures on everyday mobility behaviour, answering the following questions, among others:

  • Which transport modes were used?
  • What was the purpose and goal of the trip?
  • How are the transport systems evaluated?

All trips – whether by bus, train, car, bicycle or on foot – are to be included in the survey. Respondents can also indicate how they judge the conditions for using the various types of transport in Flensburg and whether conditions are suitable for cycling and walking. Furthermore, there is an opportunity to formulate suggestions and proposals for transport planning.

Procedure

Around 15,000 people will be randomly selected from the population register of the City of Flensburg and will be contacted in August and September 2021. The survey takes about 10-15 minutes and is voluntary. Participation is only possible for people who have previously received an access code for the online survey by post. This procedure ensures the results of the survey will be representative. The aim is that more than 3,500 people should participate in the survey. This is the equivalent of about 3.6% of the city’s population.

Survey contents

The survey includes questions about the household, the individuals and the mobility behaviour on a specified reporting day. It consists of three parts:

  • The household questionnaire contains general questions on the availability of transport and the composition of the household.
  • The individual questionnaire deals with mobility prerequisites, use of means of transport and evaluations of the different transport systems. It is to be completed by all household members who are at least 6 years old.
  • The participants should document their trips for a given reporting day in the trip report or trip log. Each person in the household who is at least 6 years old is to provide information. The trip log should also be completed if someone did not leave the house on the reporting day.

Different survey channels

There are three different ways to take part in the survey. Participation can take place via the online survey, via a written postal survey or by telephone. In any case, the selected households first receive a letter by post inviting them to participate in the online survey. However, you can choose to use a different participation method if you so wish.

In the initial letter, all the selected households are informed of their specified reporting day when the trips they undertake should be logged, and are given the access code for the online survey. In the online survey, not all questions have to be answered at once; the survey can be paused and continued at a later time.

To participate in the written survey or by telephone, the pre-paid reply card enclosed with the initial letter can be used to request the written questionnaires or indicate a preferred date for a telephone interview. The following procedure should then be followed:

  • For the written survey, the survey documentation will arrive by post. The participants fill out the questionnaires and return the documents in the pre-paid envelope provided.
  • For the telephone interview, participants are called one to two days after the specified reporting day by a trained person from the O-TON company in Dortmund. The questions are then answered on the phone. For this purpose, a preferred date for a telephone interview can also be arranged under the telephone number 0231 / 70013 994.

What happens with the data?

The survey is conducted in two steps. In the first step, individuals are randomly selected from the population register and contacted by post. In the second step, the responses of the participants are processed and evaluated. The two steps are carried out using separate datasets.

For the first step, address data is randomly selected from the population register of the City of Flensburg. This data will only be used to contact you by post. Addresses subject to a block on releasing information will not be used.

In the second step, the answers are processed and evaluated. This step is undertaken anonymously, i.e. without reference to names and addresses. The answers are grouped into categories. Care is taken to ensure that no indirect connections to individuals can be made through the evaluations and categories. For example, no evaluation categories are formed with fewer than seven individual cases as this could allow the respondents to be identified.

There is a legitimate need to conduct the survey because representative basic data is required for transport planning. Transport planning is, at least in part, a mandatory task of the municipalities. Participation in the survey is of course voluntary.

The legal provisions of the European Data Protection Regulation (GDPR) and the Schleswig-Holstein Data Protection Act (LDSG SH) are complied with. We have provided further information for you in the Data Protection Policy (download PDF).

Results

After completion of the survey, the data will be analysed. The results are expected to be available at the beginning of 2022 and will be published on this website. Among other things, the results will be incorporated in the City of Flensburg's transport model and hence in future transport planning. In addition, the results of this mobility survey will be used to assess the extent to which the objectives of the Mobility Master Plan have been achieved, moving towards climate-friendly and sustainable transport in Flensburg.
