One-way traffic in the context of Ton

In road transport, a lane is part of a roadway that is designated to be used by a single line of vehicles to control and guide drivers and reduce traffic conflicts. Most public roads (highways) have at least two lanes, one for traffic in each direction, separated by lane markings. On multilane roadways and busier two-lane roads, lanes are designated with road surface markings. Major highways often have two multi-lane roadways separated by a median.

Some roads and bridges that carry very low volumes of traffic are less than 4.6 metres (15 ft) wide, and are only a single lane wide. Vehicles travelling in opposite directions must slow or stop to pass each other. In rural areas, these are often called country lanes. In urban areas, alleys are often only one lane wide. Urban and suburban one lane roads are often designated for one-way traffic.

Fifth Avenue is a major thoroughfare in the borough of Manhattan in New York City. The avenue runs south from West 143rd Street in Harlem to Washington Square Park in Greenwich Village. The section in Midtown Manhattan is one of the most expensive shopping streets in the world.

Fifth Avenue carries two-way traffic between 143rd and 135th Streets, and one-way traffic southbound for the rest of its route. The entire avenue carried two-way traffic until 1966. From 124th to 120th Streets, Fifth Avenue is interrupted by Marcus Garvey Park, with southbound traffic diverted around the park via Mount Morris Park West and northbound to Madison Avenue. Most of the avenue has a bus lane, but no bike lane. Fifth Avenue is the traditional route for many celebratory parades in New York City and is closed to automobile traffic on several Sundays each year.

A diode is a two-terminal electronic component that conducts electric current primarily in one direction (asymmetric conductance). It has low (ideally zero) resistance in one direction and high (ideally infinite) resistance in the other.

A semiconductor diode, the most commonly used type today, is a crystalline piece of semiconductor material with a p–n junction connected to two electrical terminals. It has an exponential current–voltage characteristic. Semiconductor diodes were the first semiconductor electronic devices. The discovery of asymmetric electrical conduction across the contact between a crystalline mineral and a metal was made by German physicist Ferdinand Braun in 1874. Today, most diodes are made of silicon, but other semiconducting materials such as gallium arsenide and germanium are also used.

A turnstile (also called a gateline, baffle gate, automated gate, turn gate in some regions) is a form of gate which allows one person to pass at a time. A turnstile can be configured to enforce one-way human traffic. In addition, a turnstile can restrict passage only to people who insert a coin, ticket, transit pass, security credential, or other method of payment or verification. Modern turnstiles can incorporate biometrics, including retina scanning, fingerprints, and other individual human characteristics which can be scanned.

A turnstile can be used in the case of paid access (sometimes called a faregate or ticket barrier when used for this purpose), for example to access public transport, a pay toilet, or to restrict access to authorized people, for example in the lobby of an office building.

Charles Street, known for most of its route as Maryland Route 139 (MD 139), runs through Baltimore and the Towson area of Baltimore County. On the north end, it terminates at an intersection with Bellona Avenue near Interstate 695 (I-695). At the south end, it terminates in Federal Hill in Baltimore. Charles Street is one of the major routes through Baltimore, and is a major public transportation corridor. For the one-way portions of Charles Street, the street is functionally complemented by the parallel St. Paul Street, including St. Paul Place and Preston Gardens, Maryland Avenue, Cathedral Street, and Liberty Street.

Though not exactly at the west–east midpoint of the city, Charles Street is the dividing line between the west and east sides of Baltimore. On any street that crosses Charles Street, address numbers start from the unit block on either side, and the streets are identified as either "West" or "East," depending on whether they are to the west or east of Charles.

51st Street is a 1.9-mile (3.1 km) long one-way street traveling east to west across Midtown Manhattan.

54th Street is a two-mile-long (3.2 km), one-way street traveling west to east across Midtown Manhattan in New York City.

Oracle is a census-designated place (CDP) in Pinal County, Arizona, United States. The population was 3,686 at the 2010 Census, falling to 3,051 at the 2020 Census.

Oracle State Park is adjacent. The Arizona Trail passes through the Park and community.Oracle is the gateway to the road up the north face of Mount Lemmon, which starts off of American Avenue and currently offers a secondary route to the top. Prior to the construction of the Catalina Highway on the opposite side of the Santa Catalina range, the Oracle Control Road was the only road access to the mountain community of Summerhaven. The term "control road" derives from the fact that the direction of traffic was restricted to one-way only, either up or down at alternate times of day, to prevent motorists from having to pass one another on the narrow, steep road. This route is now popular mainly with off-road 4x4 drivers and with off-road or dual-purpose motorcyclists, and should not be attempted by regular passenger cars or street motorcycles. This road ends at the Catalina Highway near Loma Linda.

55th Street is a two-mile-long, one-way street traveling east to west across Midtown Manhattan.

U.S. Route 12 (US 12) is a part of the United States Numbered Highway System that runs from Aberdeen, Washington, to Detroit, Michigan. In the U.S. state of Indiana, it is part of the state road system. US 12 enters the state concurrent with US 20 and US 41 in Hammond. The 46.258 miles (74.445 km) of US 12 that lie within Indiana serve as a major conduit. Some of the highway is listed on the National Highway System (NHS). Various sections are rural two-lane highway, urbanized four-lane undivided highway, and one-way streets. The easternmost community along the highway is Michiana Shores at the Michigan state line.

US 12 passes through urban areas and wood lands, parallel to the Lake Michigan shoreline. The highway is included in the Lake Michigan Circle Tour and passes through Indiana Dunes National Park. Historical landmarks along the highway include the Miller Town Hall, Beverly Shores station, and the Old Michigan City Light. A memorial highway designations have been applied to the route since 1917, named for the Civil War Union Army unit.

U.S. Route 20 (US 20) in Indiana is a main east–west highway that is parallel to the Indiana Toll Road. The western terminus of US 20 is at the Illinois state line and the eastern terminus is at the Ohio state line. US 20 through Whiting, East Chicago, and Gary is concurrent with US 12 twice. The route varies between one-way, two-lane, and four-lane streets, in Northwest Indiana. From the east side of Gary to west of South Bend, US 20 is a four-lane undivided highway. The route then heads around the west and south sides of South Bend and Elkhart as a four-lane limited access divided highway. East of State Road 15 (SR 15), US 20 is two-lane rural highway.

US 20 was part of the Dunes Highway from the Illinois state line to Michigan City, concurrent with US 12. The Dunes Highway started being paved in 1922. The section of the highway that is known as Lincoln Way was part of the 1913 section of the Lincoln Highway. Indiana State Highway Commission, later renamed Indiana Department of Transportation (INDOT), began signing US 20 in 1926. US 20 went through downtown South Bend and Elkhart before the St. Joseph Valley Parkway was built. Before the parkway was completed, the route that was open to traffic was called US 20 Bypass (US 20 Byp.). A small realignment in LaGrange County was done in 2005, in which the roadway was straightened. Other small realignments included the route through Michigan City, which followed US 35 from US 12 to Interstate 94 (I-94).

Worth Street is a two-way street running roughly northwest-southeast in Manhattan, New York City. It runs from Hudson Street, TriBeCa, in the west to Chatham Square in Chinatown in the east. Past Chatham Square, the roadway continues as Oliver Street, a north-south street running one-way northbound. Between West Broadway and Church Street, Worth Street is also known as Justice John M. Harlan Way in honor of the Supreme Court justice and alumnus of the nearby New York Law School. Between Centre and Baxter Streets, Worth Street is also known as the "Avenue of the Strongest", "New York's Strongest" being a nickname for the city's Department of Sanitation.

The western end of Worth Street, between Hudson Street and West Broadway, abuts 60 Hudson Street, the former Western Union headquarters that later was converted into an internet hub. Worth Street passes through the cluster of government offices and courthouses centered on Foley Square. 125 Worth Street (at Centre Street) houses the headquarters of the New York City Health and Hospitals Corporation, the Department of Health and Mental Hygiene, and the Department of Sanitation. Additionally, the New York Supreme Court courthouses at 60 Centre Street and 80 Centre Street (the Louis J. Lefkowitz Building) and the Daniel Patrick Moynihan Federal Courthouse (Southern District of New York) at 500 Pearl Street all have entrances facing Worth Street.
