Traffic Lights
How traffic signals are designed and implemented directly impacts cyclists. For instance, poorly adjusted vehicle detector systems, used to trigger signal changes, may not correctly detect cyclists. Traffic managers in Copenhagen link cyclist-specific traffic signals on a major arterial bike lane to provide green waves for rush hour cycle-traffic. Cycling-specific measures that can be applied at traffic signals include the use of advanced stop lines and/or bypasses.
The frequency with which lights change is important to cyclists who may conserve energy by anticipating green lights ahead i.e. the shorter the interval the better for cyclists. Intersection clearance times and green wave timing may also be relevant.

Famous quotes containing the words traffic and/or lights:
“To treat a “big” subject in the intensely summarized fashion demanded by an evening’s traffic of the stage when the evening, freely clipped at each end, is reduced to two hours and a half, is a feat of which the difficulty looms large.”
—Henry James (1843–1916)
“To motorists bound to or from the Jersey shore, Perth Amboy consists of five traffic lights that sometimes tie up week-end traffic for miles. While cars creep along or come to a prolonged halt, drivers lean out to discuss with each other this red menace to freedom of the road.”
—For the State of New Jersey, U.S. public relief program (1935-1943)
