Contra-Flow Bike Lanes allow cyclists to travel in the opposite direction of vehicle traffic flow. Contra-Flow lanes are found on one-way streets that then allow two-way directional traffic for cyclists. Left-Side Bike Lanes are lanes placed on the left side of one-way streets, or along a median on two-way divided streets. The Manual on Uniform Traffic Control Devices (MUTCD) by the U.S. Department of Transportation Federal Highway Administration (FHA) gives standards of how bike lanes should be implemented regarding pavement markings and signage. These can include the word, symbol, and arrow size to be used in a bike lane and the width of the lane itself, which ranges from 5–7 feet. Cities across America are actively expanding their amount of bike lanes, such as in Boston, Massachusetts where they have created city-wide goals, Go Boston 2030, to increase their bike network. Europe In France, segregated cycling facilities on the carriageway are called bande cyclable, those beside the carriageway or totally independent ones piste cyclable, all together voie cyclable. In Belgium, traffic laws do not distinguish cycle lanes from cyclepaths. Cycle lanes are marked by two parallel broken white lines, and they are defined as being "not wide enough to allow use by motor vehicles". There is some confusion possible here: both in French (piste cyclable) and in Dutch (fietspad) the term for these lanes can also denote a segregated cycle track, marked by a road sign; the cycle lane is therefore often referred to as a "piste cyclable marquée" (in French) or a "gemarkeerd fietspad" (in Dutch), i.e. a cycle lane/track which is "marked" (i.e. identified by road markings) rather than one which is identified by a road sign. In the Netherlands the cycle lane is normally called "fietsstrook" instead of "fietspad". Asia Commuting via bicycle is quite common in some Asian countries like Japan, in which bicycle ridership has been increasing dramatically since the 1970's. Despite this fact however, many parts of Japan have been slow to adopting effective and safe means of transport, so in recent times there have been steps taken to promote biking in the nation's largest city, Tokyo. Many bike lanes in Tokyo have been constructed to allow the 2 directional flow of traffic in only one lane but add a physical separation between pedestrians, bike lanes, and the roads. In addition to these types of bike lanes, there are other forms of bike lanes
