Buffered Bike Lane
Buffered Bike Lanes are standard bike lanes paired with a designated horizontal buffer space , separating the bicycle lane from the adjacent motor vehicle travel lane and / or parking lane . This type of bikeway provides greater distance between vehicles and bicycles ; provides space for bicyclists to pass each other ; provides greater space for bicycling without making the bike lane appear so wide that it might be mistaken for a travel lane ; and encourages bicycling by contributing to the perception of safety .

Separated Bikeway
A separated bikeway , also called a cycletrack , provides dedicated street space , typically adjacent to outer vehicle travel lanes , with physical separation from vehicle traffic , designated lane markings , pavement legends , and signage . Physical separation may consist of plastic posts , parked vehicles , raised median , or a curb ( if the separated bike lane is raised to sidewalk level ). Separated bikeways reduce conflicts between people biking and motorists . They also provide more physical protection that further reduces the risk of severe conflicts between bicycles and vehicles on the road . Separated bike lanes can also help manage or reduce vehicle speeds as some of the design features can have a traffic calming effect .
