Upgrade the bike storage facilities at government buildings to encourage biking to work, then link the usage of these facilities to a commiserate reduction of any transportation subsidy the employee receives. So, if I bike to work thrice a week, my transportation subsidy is likewise automatically reduced by the cost of Metro for those three days. Such a linkage could be done through an employees badge which would be scanned upon placing their bike in the facility.
