Reasons leading cities find bike lanes helpful:

- They can help reduce injuries to cyclists and motorists: Marked and separated bike lanes can help reduce bicyclist and motorist interactions. While some bike lanes have painted lines separating bike lanes from sidewalks and the road, others have physical barriers between cars and cyclists.

- They may help improve the flow of traffic: City bicycles no longer required to avoid vehicles or pedestrians and vice versa; instead, they can move forward at more consistent speeds.

- They can be better for the environment: According to AARP.org, choosing to bike for short commutes helps reduce carbon emissions as much as 2,000 pounds annually.
