Bicycle Lanes are portions of the traveled way designed for bicycle use, and are established with appropriate signs and pavement markings. Bike lanes are usually one-way facilities that carry bicyclist traffic in the same direction as the adjacent roadway traffic. Under some circumstances, however, bike lanes can also be contra-flow, allowing bicycles to travel in two directions on one-way streets.

(Please remember, bicyclists are not required to use bike lanes and may also be operating in the adjacent lanes)

Cycle Tracks, both one-way and two-way, are facilities along the right-of-way, divided from motor vehicular and pedestrian traffic by some form of vertical separation, such as curbs, parked cars, bollards, or detectable barriers.

Marked Shared Lanes are travel lanes with specific bicycle markings, often referred to as sharrows. These markings are designed to assist bicyclists with lateral positioning in a shared lane and to correct direction of travel, while also alerting motorists of the position bicyclists are likely to occupy and encouraging the safe passing of bicyclists.

Off-Road Facilities, or shared use paths, are facilities on an exclusive right-of-way separated from a roadway, with minimal cross flow by motor vehicles. Shared use paths are designed to accommodate a variety of users for utilitarian and recreational purposes, including walkers, bicyclists, joggers, skaters, pets, and, occasionally, equestrians.

On-Road Facilities are street-level improvements visible on the roadway. They may include bicycle lanes, cycle tracks, usable shoulders, and/or marked shared lanes.

Programmed Bicycle Facilities are those listed in Statewide Transportation Improvement Plan (STIP), under construction, or in design.

Proposed Bicycle Facilities are those recommended for study, design or construction in either Regional Transportation Improvement Plans (TIPs) developed by Metropolitan Planning Organizations (MPOs), local bicycle plans developed by municipalities, projects proposed by other state agencies, often in collaboration with interest groups, or proposals from public participation during outreach efforts.

Signed Bicycle Routes are facilities marked with signs that are intended to guide bicyclists onto or along particular roadways or paths between a starting location and an ending location.

Unimproved Bicycle Routes are travel routes without visible street level accommodations, such as pavement markings or signs. These routes may be found in bicycle tour books, on local maps, and on web sites. Bicyclists must rely on their own route information to determine the start and end points, and the routing, rather than referring to pavement markings or signs.
