Class I bikeways, also known as bike trails 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.

These are designated lanes for biking along streets marked by pavement striping and signage. Some bike lanes may incorporate additional buffer space to further separate bicyclists.

These are designated biking routes, typically on neighborhood streets. They may incorporate traffic calming devices such as traffic circles, intersection improvements, and other safety enhancements to lower vehicle speeds and improve rider comfort.

These are also known as separated bike lanes because they provide a physical barrier between the bicyclist and traffic lanes, using treatments such as a curb, parked cars, or planters. Protected bike lanes can increase comfort and reduce the level of stress for bicyclists.
