Improving safety around Danish schools

We have been thrilled using DataFromSky to carry out analysis of the morning rush at all schools in the Viborg Municipality as it provides us with a good and well-documented overview of the traffic situation around school start in the morning.

Traffic safety around schools has been the local government’s main focus point for many years. Wanting to improve traffic safety around schools, several Danish municipalities asked our partner COWI to conduct a traffic analysis of local school areas to pinpoint potentially problematic areas. Thanks to drone technology and DataFromSky’s TrafficSurvey service, COWI was able to deliver an impressive documentation of the situation.

As road safety around schools is crucial, the municipality of Viborg wanted to pinpoint all potentially problematic areas. The main goal was to determine if the current design was safe for both cyclists and pedestrians arriving to school, as well as to get deeper insight into road users’ behavior (parking habits, use of zebra crossings, etc.).

All of these data should serve as a basis for new safety measures that will be used during upcoming design adjustments.

Conducting the analysis

Instead of using old-fashioned manual counting, COWI decided to utilize a more modern approach, recording each of the areas with a drone capable of capturing the entire area from a single spot. The recording was done 20 minutes before 8 AM, when most of the lessons start in Denmark. This will ensure that the drone recording captures the period with the heaviest traffic in the areas. 

Afterwards, COWI used TrafficSurvey online platform to get the desired insights. This way, it was possible to track down the movements of cars, bikes and pedestrians and investigate the crossings of their trajectories. Furthermore, they received an insight into traffic counts and people’s preferences of roads and parking lots.

By using DataFromSky and drones, you get a really nice overview and documentation of problematic areas. You're also able to make very nice visualizations and recordings.

Thanks to the rich data provided by the TrafficSurvey service, COWI was able to deliver elaborate documentation of the situation, as well as detailed information on traffic counts, pedestrian & car trajectories, zebra crossings or parking lot usage .

Several problematic areas were pinpointed around the schools, making the municipality aware of potential risks.

In many cases, new measures were undertaken to redirect the traffic and minimize the risk of collisions and make the journey to school safer for everyone.

About Viborg municipality

Located on Jutland peninsula in northern Denmark, the municipality consists of 45 towns, with Viborg town being the capital. With the number of inhabitants of around 100 000, Viborg municipality accounts for one of the larger Danish municipalities.


26 schools analyzed

School areas were analyzed using drone recordings to get a complete overview of the traffic situation upon school start.

Minimizing collision risks

Lots of children arrive at school on foot or by bike, being endangered by car users. One of the goals of the study was to reduce the risk of accidents.

Detailed analysis
per road user

Thanks to DFS TrafficSurvey, COWI was able to track all road users (mainly pedestrians, cyclists and vehicles) and analyze their trajectories individually.
