More and more cities are lowering the speed limit within built-up areas to 30 km/h. This is being done out of concern for road safety, quality of life and sustainability. In 2021, the four largest cities (G4): Amsterdam, Rotterdam, Utrecht and The Hague sent an urgent letter to the House of Commons calling for the accelerated introduction of 30 km/h as the standard.

Effects in Amsterdam after one year
According to figures from the municipality of Amsterdam:

• 11% fewer accidents on 30 km/h roads.
• 15% fewer incidents involving pedestrians and (e-)cyclists.
• 63% of motorists (almost) adhere to the new limit.
• On average, 1.5 decibels less traffic noise

Alderman Melanie van der Horst emphasises that the measure contributes to a safer city, despite initial resistance.

NPO Radio 1 focused on this topic because, as of today, a maximum speed limit of 30 km/h applies in a large part of Haarlem’s city centre.

Jeroen Borst, CEO of Scenexus, was asked for his reaction during the broadcast. He indicated that the introduction of 30 km/h has positive effects, provided that it is implemented carefully.
