There are  of cycle paths and routes in Paris. These include ''piste cyclable'' (bike lanes separated from other traffic by physical barriers such as a kerb) and ''bande cyclable'' (a bicycle lane denoted by a painted path on the road). Some  of specially marked bus lanes are free to be used by cyclists, with a protective barrier protecting against encroachments from vehicles. Cyclists have also been given the right to ride in both directions on certain one-way streets.
