Reversible laneA reversible lane, also known as variable lane, dynamic lane, tidal flow and formerly suicide lane, is a managed lane in which traffic may travel in either direction, depending on certain conditions. Typically, it is meant to improve traffic flow during rush hours, by having overhead traffic lights and lighted street signs notifying drivers which lanes are open or closed to driving or turning.
HighwayA highway in the broadest sense of the term is any public or private road or other public way on land, including not just major roads but also other public roads and rights of way. In the United States, the term is used to describe major roads. It is sometimes used casually as a synonym of freeway, or expressway, denoting a controlled-access highway. According to Merriam-Webster, the use of the term predates the 12th century.
LaneIn 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, generally separated by lane markings. On multilane roadways and busier two-lane roads, lanes are generally designated with road surface markings. Major highways often have two multi-lane roadways separated by a median.
Head-on collisionA head-on collision is a traffic collision where the front ends of two vehicles such as cars, trains, ships or planes hit each other when travelling in opposite directions, as opposed to a side collision or rear-end collision. Rail transportWith railways, a head-on collision occurs most often on a single line railway. This usually means that at least one of the trains has passed a signal at danger, or that a signalman has made a major error.

United StatesThe United States of America (USA), also known as the United States (U.S.) or America, is a country primarily located in North America. It is a federal republic consisting of 50 states and a federal capital district, Washington, D.C. The 48 contiguous states border Canada to the north and Mexico to the south, with the semi-exclave of Alaska in the northwest and the archipelago of Hawaii in the Pacific Ocean.
Road surface markingRoad surface marking is any kind of device or material that is used on a road surface in order to convey official information; they are commonly placed with road marking machines (also referred to as road marking equipment or pavement marking equipment). They can also be applied in other facilities used by vehicles to mark parking spaces or designate areas for other uses.
One-way trafficOne-way traffic (or uni-directional traffic) is traffic that moves in a single direction. A one-way street is a street either facilitating only one-way traffic, or designed to direct vehicles to move in one direction. One-way streets typically result in higher traffic flow as drivers may avoid encountering oncoming traffic or turns through oncoming traffic.
AlleyAn alley or alleyway is a narrow lane, path, or passageway, often reserved for pedestrians, which usually runs between, behind, or within buildings in towns and cities. It is also a rear access or service road (back lane), or a path, walk, or avenue (French allée) in a park or garden. A covered alley or passageway, often with shops, may be called an arcade.
Controlled-access highwayA controlled-access highway is a type of highway that has been designed for high-speed vehicular traffic, with all traffic flow—ingress and egress—regulated. Common English terms are freeway, motorway, and expressway. Other similar terms include or thruway and parkway. Some of these may be limited-access highways, although this term can also refer to a class of highways with somewhat less isolation from other traffic.
Road transportRoad transport or road transportation is a type of transport using roads. Transport on roads can be roughly grouped into the transportation of goods and transportation of people. In many countries licensing requirements and safety regulations ensure a separation of the two industries. Movement along roads may be by bike, automobile, bus, truck, or by animal such as horse or oxen.
Back roadA back road is a secondary type of road usually found in rural areas. A country lane is a narrow road in the countryside. SafetyBack roads tend to have narrow lanes, limited or non-existent shoulders, inconsistent pavement with gravel patches, sharp curves, steep slopes, and poor visibility. The majority of American back roads were built early in US road history, prior to modern safety standards and vehicle designs.Median stripReserved area that separates opposing lanes of traffic on divided roadways Typical left-hand motorway road layout in Ireland and South Africa Divided median strip on a boulevard in Huizhou, China A median strip, central reservation, roadway median, or traffic median is the reserved area that separates opposing lanes of traffic on divided roadways such as divided highways, freeways, and motorways.*As an Amazon Associate I earn from qualifying purchases.
