Improving safety around Danish schools

Longing to protect the safety of children, 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 DFS analytical services, COWI was able to deliver an impressive documentation of the situation.

Project highlights:

School areas were analyzed using drone recordings to get details about children commuters’ safety

collision risks

Lots of school kids arrive at school on foot or by bike, being endangered by car users. One of the goals of the study was to help reduce the risks.


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


Viborg municipality in Denmark is responsible for all the primary and secondary schools in its area. As road safety is crucial in the schools’ surroundings, the municipality wanted to pinpoint all the problematic areas. The main goal was to understand if the current design was safe for both cyclists and pedestrians coming to and back from school, as well as to get deeper insight into drivers’ 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.

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.

Conducting the analysis

Instead of using old-fashioned manual counting, COWI decided to utilize modern approach, recording each of the areas with a drone capable of capturing the whole situation from a single spot. Usually, the recording was done 20 minutes before 8 AM, when most of the lessons start in Denmark, to capture the heaviest traffic in the areas.

Afterwards, COWI used DFS 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 the traffic counts and people’s preferences of roads and parking lots.

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 responsible people aware of the potential risks. In many cases, new measures were undertaken to redirect the traffic and minimize the risk of collisions and make the journey to the schools safer for everyone.safer for everyone.
"We have been thrilled using Data From Sky 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."
