Paths: known as bike paths or shared-use paths, are facilities with exclusive right of way for bicyclists and pedestrians, away from the roadway and with cross flows by motor traffic minimized. Some systems provide separate pedestrian facilities. Class I facilities support both recreational and commuting opportunities. Common applications include along rivers, shorelines, canals, utility rights-of-way, railroad rights-of-way, within school campuses, or within and between parks.

Bike Lane: along streets and defined by pavement striping and signage to delineate a portion of a roadway for bike travel. One-way facilities, typically striped next to motor traffic in the same direction. Contraflow bike lanes are used on one-way streets for traveling in the opposite direction.

Buffered Bike Lane: more separation from an adjacent traffic lane and/or between bike lane and street- parking by chevron/diagonal markings. Useful on streets with higher motor traffic speeds or volumes.

Bike Route: designate a preferred route on streets with motor traffic (no dedicated bikeway) to provide continuity to bikeway network. Not appropriate for roadways with higher motor traffic speeds or volumes. Established by placing signs and optional shared roadway markings (sharrow).

Bicycle Boulevard: shared roadway intended to prioritize bike travel. Typically sited on streets without large truck/transit vehicles where traffic volumes and speeds are low, or can be reduced with traffic calming.

Separated Bikeway/Cycle Track: (protected bike lane) for only bicycles, physically separated from motor traffic with a vertical feature. Separation may include, but not limited to, grade separation, flexible posts, inflexible barriers, or on-street parking. Can provide for one- or two-way travel.

By providing physical separation from motor traffic, these can reduce the level of stress, improve comfort for more types of bicyclists, and contribute to an increase in bicycle volumes and mode share.
