Good weather, improved infrastructure and the economic situation helped cut the traffic congestion by 30% in the first three months of this year, the ANWB motoring organisation said at the weekend.

Traffic congestion fell to its lowest level since 2006 in the first quarter of 2012, the ANWB said. Congestion is measured by multiplying the length of a jam by the duration.
In particular, efforts are being made to reduce congestion on the A4 between The Hague and Amsterdam, the ANWB said.
