Can there be speed reduction measures on my street?

To determine whether speeding occurs structurally somewhere, the so-called 85 percentile is used. The 85 percentile is a speed value derived from speed measurements. 85% of road users drive this speed or slower. If this value is high above the speed limit, the municipality notifies the police. They then determine whether to proceed with enforcement.

In almost all cases it was found that there was no structural speeding. Speed reduction measures are therefore not necessary in most cases.

The municipality's policy is that as soon as major maintenance is carried out on a street, the existing layout of the road is reviewed. The municipality then takes into account any accidents that have occurred, speeds actually driven and the Sustainable Safety guidelines. On this basis, it will be determined whether speed reduction measures will be applied. Of course, the final decision as to whether to implement the measures is made by the municipality, and the financial resources must be sufficient.

Outside of maintenance work, expansion of speed reduction measures is only possible on a very limited scale. Only in situations of urgency is it considered early on whether the road layout should be supplemented with a speed hump. The urgency here consists mainly of injury accidents.

On roads with a speed limit of 50 km/h or 80 km/h, no speed reduction measures are applied in principle.
