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:
“Cry;—and upon thy so sore loss
Shall shine the traffic of Jacob’s ladder
Pitched betwixt Heaven and Charing Cross.”
—Francis Thompson (1859–1907)
“Y’know scientists are funny. We probe and measure and dissect. Invent lights without heat, weigh a caterpillar’s eyebrow. But when it comes to really important things we’re as stupid as the caveman.... Like love. Makes the world go ‘round, but what do we know about it? Is it a fact? Is it chemistry? Electricity?”
—Martin Berkeley, and Jack Arnold. Helen Dobson (Lori Nelson)
