Amsterdam city council has announced plans to make parking on the outskirts of the city even more appealing to visitors. The four existing park-and-ride facilities at Zeeburgereiland, under the Sloterdijk train station, in the parking garage at the Olympic Stadium and under the Amsterdam ArenA currently charge 5.50 for 24 hours parking. This fee includes free public transport into the city centre. Under the new plan, the fee would be reduced to 1 per day, with two free tickets on public transport thrown in. The measures are aimed at reducing traffic in the city centre particularly on weekends, when out-of-town shoppers flock to Amsterdam. It is not known when the new fee will come into effect.
