  2. Stop and yield lines - Wikipedia

    en.wikipedia.org/wiki/Stop_and_yield_lines

    In some cases stop or yield lines are used in advance of mid-block crosswalks. A stop line is a type of marking used to inform drivers of the point where they are required to stop at an intersection or roundabout controlled by a stop sign or traffic signal. It is also known as a stop bar. [2]

    However, the Federal MUTCD requires that a stop line, if used, shall be at least 4 feet from the nearest travel lane. [23] Line of sight for corner sight distance is to be determined from a 3 and 1/2-foot eye height at the vehicle driver's location on the minor road to a 4 and 1/4-foot object height in the center of the approaching lane of the ...

  4. Crosswalks in North America - Wikipedia

    en.wikipedia.org/wiki/Crosswalks_in_North_America

    The stop line acts as the legally mandated stopping point for vehicles, and discourages drivers from stopping in the middle of the crosswalk. [4] The other method involves the use of the more easily visible "continental stripes" (like the UK's zebra crossings), which are sets of multiple bars across the crosswalk itself that are perpendicular ...

    A stop line is always represented by a white thick traversal continuous line, but a give way line may be represented by a white thick dashed line as rectangles (Germany, France, Spain) or by a double-dashed line (United Kingdom) or by a white line of triangles (Austria, Italy, Liechtenstein, the Netherlands, Norway, and Switzerland).

    In New Zealand, where traffic is on the left, when a road is given a green light from an all-direction stop, a red arrow can continue to display to turning traffic, holding traffic back while a pedestrian crossing on the side road is given a green signal (for left turns) or while oncoming traffic goes straight ahead and there is no permissive right turn allowed (for right turns).

  7. HAWK beacon - Wikipedia

    [1]: 523 However, at a HAWK beacon, an alternating flashing red aspect instructs drivers to stop and proceed when clear, and is not supposed to be treated as stop and stay by drivers. Emergency-vehicle hybrid beacons, for emergency vehicle facilities (i.e. fire stations), use the same signal head design, and uses an alternating flashing red ...

    I was at a sidewalk intersection and almost didn’t see the bicycle speeding toward me. At 80 years it is not easy to make an abrupt stop. When I chided the rider as he swept past me his reply ...

  9. Vertical queue - Wikipedia

    en.wikipedia.org/wiki/Vertical_Queue

    The vertical queue is unitless, and is simply representative of the number of vehicles which are delayed at a given point in a system. [2] This is clearly not possible in real life, but the assumption allows vehicles in an analysis to drive at the free flow speed until reaching the point of congestion. A vehicle does not have to travel at less ...
