The 2011 Census showed that 5.9 percent of commuters in Dublin cycled. A 2013 report by Dublin City Council on traffic flows crossing the canals in and out of the city found that just under 10% of all traffic was made up of cyclists, representing an increase of 14.1% over 2012 and an 87.2% increase over 2006 levels and is attributed to measures, such as, the Dublinbikes bike rental scheme, the provision of cycle lanes, public awareness campaigns to promote cycling and the introduction of the 30 km/h city centre speed limit.
