Travel behaviour survey (OVG/ECD)

Brussels Mobility studies the travel behaviour of the residents of the Brussels Capital Region. This survey studies mobility characteristics and habits of families and individuals.

What does this survey teach us?

We get a helicopter perspective of Brussels mobility. For example, we have learned from the last edition that 36% of journeys by Brussels residents are made on foot, 9% by bike, 22% by bus/tram/metro and 27% by car (as driver or passenger). We know that Brussels residents make an average of 2.9 trips per day, and that 86% of these trips are internal to the Brussels Capital Region, meaning that the starting and ending points are within the Region. We also know that the average travel distance for internal trips is 3.3 km. We know that 46% of households own a car (including company cars), which means that 54% of Brussels households do not own a car. On the other hand, 47% of families own at least one bicycle and as many as 70% of respondents say they have a STIB subscription. But the greatest value of the survey probably lies in the in-depth analyses, where different variables can be combined, such as the link between household income and car use, the differences between neighbourhoods or between age groups in terms of car or bicycle ownership, or the impact of distance on the choice of means of transport.

Who can participate and how does it work?

A representative sample of Brussels residents aged 6 and over is drawn from the national register. These people are called by letter to fill in a questionnaire online and note the trips they make during a whole day.

Why is it important?

It is important for the government to monitor the latest evolution of its residents' mobility in order to make appropriate policy choices. The survey offers a broad knowledge base that can be used to evaluate current policy and assess the relevance of future policy.


The most recent survey, OVG/ECD 6, ran from October 2021 to October 2022. 2,685 surveys were collected in the Brussels Capital Region. This is the first measurement of travel behaviour since the Covid pandemic.

The English-language summary of the survey is available for download below. On the French and Dutch versions of this page, the full reports and questionnaires are available in either language.
