Bike lane

A portion of a roadway designated for bicycle travel, usually marked by pavement lines, symbols, or signs. Its design determines how bicycle traffic interacts with motor vehicles, pedestrians, and intersections.

Road surface marking: A symbol, line, or pattern applied to a road surface to guide or regulate traffic. Painted lines and bicycle symbols distinguish the lane and communicate its intended use.
Protected bike lane: A bicycle lane separated from motor traffic by a physical barrier or level difference. Physical separation changes how directly motor vehicles can enter the bicycle space.
Cycle track: A bicycle facility physically separated from motor traffic, often at sidewalk level or behind a barrier. This related facility offers more separation than a conventional painted bike lane.
Cyclist safety: The reduction of injury and fatality risks for people riding bicycles. Lane separation, visibility, and intersection treatment influence cyclists’ exposure to crashes.
Bicycle boulevard: A low-traffic street designed to prioritize bicycle travel without necessarily having a dedicated lane. It shows how a street can favor cycling without allocating a marked roadway strip.
Buffered bike lane: A bicycle lane with a painted buffer separating it from adjacent traffic or parking. Its marked buffer adds lateral space without a physical barrier.
Bike box: A marked waiting area that lets cyclists position ahead of motor vehicles at a signalized intersection. It gives cyclists a visible position for starting ahead of queued traffic.
Induced demand: An increase in travel that follows an expansion or improvement of transport capacity. A more usable cycling route can attract trips that previously used other modes or were not made.
Road diet: A redesign that reallocates road space, often by reducing motor-vehicle lanes. Reducing vehicle lanes can create space for a dedicated bicycle lane.
Contraflow cycling: Bicycle travel permitted opposite the direction of motor traffic on a one-way street. A bike lane can provide a marked, predictable route against one-way vehicle flow.
