(Formerly) Northside Drive (US 41/SR 3) in Atlanta: Until 2009, the center lane of three between Arden Road NW and Interstate 75 was reversed using overhead lane-use control signals. This reversible travel lane was removed in multiple phases between 2009 and 2014 and replaced with a two-way left turn lane. [18]
Contraflow lane reversal is the altering of the normal flow of traffic, typically on a controlled-access highway (such as a freeway or motorway), to either aid in an emergency evacuation (the most common usage of the term in the United States) or, as part of routine maintenance activities, to facilitate widening or reconstruction of one of the highway's carriageways (the most common usage in ...
This is intended to avoid confusion between transit signals and main traffic signals at intersections where both sets are visible. In Russia, transit signals consist of 4 white lights, forming a "T". The bottom light is always illuminated when transit vehicles have permission to proceed.
In Australia and New Zealand, the terminology is different. A "phase" is a period of time during which a set of traffic movements receive a green signal - equivalent to the concept of a "stage" in UK and US. One electrical output from the traffic signal controller is called a "signal group" - similar to the UK and US concept of "phase".
Lanes with double broken yellow lines on each side are reversible, [52] and lane control signals are used to indicate which direction traffic in such lanes is supposed to travel. The solid white line on the right side is called the ' fog line ' used to help cars stay in their lane during foggy conditions and help pedestrians stay off the road.
In certain situations, reversible lanes will be contraflow for a portion of the day. The Lincoln Tunnel XBL to the Lincoln Tunnel is a contraflow exclusive bus lane for buses during the morning peak period. [1] The XBL lane is fed by the New Jersey Turnpike at Exits 16E and 17, and New Jersey Route 3.
