Traffic jams are set to grow by up to 14% and rush hour car journeys times will increase by between 29% and to 46% in the short term if the government does not change its policy on roads.

This is the conclusion of a report by the institute for mobility policy (KiM), says Tuesday’s Volkskrant.
The KiM took into account existing plans for new or wider roads up to 2012 but said that, based on past performance, only 70% of these will be realised.
KiM director Carl Koopmans warns that roads are becoming congested in new places and that traffic jams are lasting longer.
‘In increasingly more places in the Randstad [urban region including Amsterdam, Rotterdam, Utrecht and The Hague] the morning and afternoon rush hours are merging.
‘On some motorways, such as the A13 and A2, there is almost no period when there are no jams,’ he told the Volkskrant.
