CIP Glossary


Bicycle Facilities There are three types of bicycle facilities identified in the California Highway Design Manual. Bike paths (Class I), bike lanes (Class II), bike routes (Class III) and cycle tracks (Class IV).
Bike paths (Class I)4280616133_3d2a7faed6_b

Also termed shared-use or multi-use paths, are paved right-of-way for exclusive use by bicyclists, pedestrians and those using non-motorized modes of travel. They are physically separated from vehicular traffic and can be constructed in roadway right-of-way or exclusive right-of-way. Bike paths provide critical connections in the City where roadways are absent or are not conducive to bicycle travel.

Bike lanes (Class II)38815650630_b4a999fd09_b

Are defined by pavement striping and signage used to allocate a portion of a roadway for exclusive or preferential bicycle travel. Bike lanes are one-way facilities on either side of a roadway. Whenever possible, bike lanes should be enhanced with treatments that improve safety and connectivity by addressing site-specific issues, such as additional warning or wayfinding signage.

Bike routes (Class III)Bike routes (Class III)

Provide shared use with motor vehicle traffic within the same travel lane. Designated by signs, bike routes provide continuity to other bike facilities or designate preferred routes through corridors with high demand. Whenever possible, bike routes should be enhanced with treatments that improve safety and connectivity, such as the use of "Sharrows" or shared lane markings to delineate that the road is a shared-use facility.

Cycle tracks (Class IV)Cycle tracks (Class IV)

Also referred to as protected bikeways, are exclusive bike facilities that combine the user experience of a separated path with the on-street infrastructure of a conventional bike lane. A cycle track is physically separated from motor traffic and distinct from the sidewalk. The separation maybe in the form of posts, parked cars or a combination of both.
