How best to visualise the simulation of the impact of a road closure on the traffic in the surrounding streets in an unambiguous and comprehensive way?
That was the question that triggered the DUET technical team to create the delta layer.
The delta layer shows – at a glance – where traffic volumes increase due to an intervention (pink colours) and where they decrease (green colours).
By using colour gradients, visitors immediately get an idea of the extent of the impact. More intensive colours indicate higher impact.
