Do you remember when you first launched a digital campaign to inform road users about disruption caused by roadworks?
Did that feel like a logical step at the time, or were you still trying to build support for digital communication within the traffic management plan?
Digital traffic management has come a long way in recent years. Whereas campaigns used to focus primarily on maximising reach, the emphasis today is much more on behavioural change, the perception of disruption and measurable impact. In this blog, we share the experience we have gained from hundreds of campaigns and show you what concrete results you can expect today.
Before we go into detail, here is a brief explanation of Online Traffic Management (OTM). As far as we are concerned, we might as well just call this digital traffic management. There are many different terms in use in the market, but ultimately it all boils down to the same goal: helping road users make the right choices at the right time.
Our approach consists of four parts:

In the early days of digital advance notifications, the focus was mainly on reach. The more people you reached, the more successful the campaign was considered to be.
Fortunately, we are seeing this picture change. Increasingly, campaigns are being assessed on the basis of KPIs that genuinely reflect effectiveness. Consider, for example:
Is the effect of digital measures always fully measurable and directly attributable to a single campaign? The honest answer is: no.
Traffic behaviour is influenced by a number of factors. Nevertheless, in practice we can clearly see that a smart combination of physical and digital measures leads
to changes in travel behaviour.
We saw a good example of this during the works on the A12 Concrete IJssel Bridge.
On Wednesday 8 April, it emerged that motorists were driving an average of seven minutes faster than usual during the morning rush hour. At that point, the temporary traffic management system was not yet fully operational, although the communication campaign announcing the start of the works had already begun.
The conclusion? Many road users had adjusted their behaviour in advance:
And that, precisely, was the aim of the campaign. The image below shows that it was a lot quieter on Wednesday 8 April.


What do the figures show?
On average, 79.9% of all respondents in 2025 and 2026 stated that they had been informed in advance about upcoming roadworks. This is a strong KPI that can increasingly be used in tenders and evaluations. This shifts the focus from:
to:
No. Our research actually shows that physical and digital communication reinforce one another. Road users still obtain information from:
Physical measures therefore remain essential. However, we do see clear differences between types of projects. In municipal projects, physical communication often still plays a more dominant role in road users’ information-seeking behaviour. In projects run by Rijkswaterstaat, on the other hand, we see that digital channels are used more frequently. Speed and journey distance may play an important role in this.

We believe that digital traffic measures should now be an integral part of the communication strategy surrounding roadworks, for both small and large-scale projects.
Of course, the optimal approach varies from project to project. The right mix of navigation, social media, advertisements, real-time updates and analysis depends on:
We advise project managers, environmental managers and traffic managers on this on a daily basis. Curious to find out what this could mean for your project?
