Measuring is Knowing! New Traffic Monitoring Campaign is Underway in Flanders

Updated: Mar 21

After the Easter holidays, the city of Sint-Niklaas will try out new traffic measures to make the school environment of the Vogelkeswijk safer and healthier. COMPAIR will be supporting the city of Sint-Niklaas in evaluating the impact of recent mobility policies on traffic flows and air quality in affected areas. Will there be less cut-through traffic as a result of the new circulation plan? What will be effect of the 30 km/h speed limit? Will air quality get better?

These are some of the questions that citizens in Sint-NIklaas will help to answer. 10 local residents are already counting traffic in and around the Vogelkeswijk with a smart traffic sensor. 10 devices have been installed, providing a good picture of the traffic intensity in Vogeltjeswijk. We see that during off-peak hours during the week, the intensities decrease and it is mainly the streets with the cut-through traffic that see the rise in vehicles, which makes sense from a traffic engineering perspective. See figure below (yellow = less traffic, purple = more traffic).

If you live in the area, you will undoubtedly be able to qualify these findings based on your field knowledge and more localised insights. Have you made a striking observation or do you see a certain pattern emerging? Let us know!

You can view the data of your Telraam device and that of other residents in the neighborhood here.

We will organize a data café on 16 May 2024, where we will explain the interim results and give you the opportunity to discuss them.

If you have any questions in the meantime, do not hesitate to contact. Send your queries or comments to


The COMPAIR team in collaboration with the City of Sint-Niklaas
