€ per each km of home-work travel
Some countries already provide people who commute to work by bicycle with a reimbursement for every km ridden. Other public authorities are getting inspired by such measures, and are now considering to introduce similar ones on their own territory (the city of Milan is about to adopt a French-like system). These project offer economic reward for commuting by bicycle, and often reveal themselves to be extremely effective.
