Gradual change made the process politically feasible andgave people the opportunity to incrementally adjust theirbehavior. Lanes of car traffic and parking spaces in the city center were eliminated slowly, 2-3% per year. The freed up space was put to new uses, including bicycle and bus lanes. One third of Copenhagen commuters now travel by bicycle, with 60-70% of cyclists choosing to pedal even through rain and winter cold. Four times as many people come to the city center now than thirty years ago. Traffic jams are a thing of the past.
