Lane in the context of "Roadway"

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, dual carriageways, freeways, and motorways. The term also applies to divided roadways other than highways, including some major streets in urban or suburban areas. The reserved area may simply be paved, but commonly it is adapted to other functions; for example, it may accommodate decorative landscaping, trees, a median barrier, or railway, rapid transit, light rail, or streetcar lines.

Road 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. In some countries and areas (France, Italy, Czech Republic, Slovakia etc.), road markings are conceived as horizontal traffic signs, as opposed to vertical traffic signs placed on posts.

Road surface markings are used on paved roadways to provide guidance and information to drivers and pedestrians. Uniformity of the markings is an important factor in minimising confusion and uncertainty about their meaning, and efforts exist to standardise such markings across borders. However, countries and areas categorise and specify road surface markings in different ways—white lines are called white lines mechanical, non-mechanical, or temporary. They can be used to delineate traffic lanes, inform motorists and pedestrians or serve as noise generators when run across a road, or attempt to wake a sleeping driver when installed in the shoulders of a road. Road surface marking can also indicate regulations for parking and stopping.

An 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. The origin of the word alley is late Middle English, from Old French: alee "walking or passage", from aller "to go", from Latin: ambulare "to walk".

The local–express lane system is an arrangement of carriageways within a major highway where long distance traffic can use inner express lanes with fewer interchanges compared to local traffic which use outer local lanes that have access to all interchanges. This can also be called a collector/distributor lane system within a single interchange. One of the longest examples is Highway 401 in Toronto, where highway ramps between express and local lanes cross over one another; these are commonly known as braided ramps and in Toronto as a basketweave.

Some places may have only three carriageways on the highway instead of four, utilizing one directional express lanes. They may be permanent, or they can be reversible express lanes such as in Seattle where they alternate direction.

A single carriageway (British English) is a road with one, two or more lanes arranged within a one carriageway with no central reservation/median strip to separate opposing flows of traffic. A single-track road is a type of single carriageway with a single lane with passing places for traffic in both directions. An undivided highway (American English) is the term used for motorways with two or more lanes with no central reservation/median strip. Road traffic safety is generally worse for high-speed single carriageways than for dual carriageways due to the lack of separation between traffic moving in opposing directions.

Yamuna Expressway is a 6-lane (expandable to 8), 165.5 km (102.8 mi) long access-controlled expressway in the Indian state of Uttar Pradesh. It is presently India's sixth longest expressway and connects Greater Noida with Agra. It was built to de-congest the older Delhi–Agra national highway (NH-2) or Mathura Road.

The expressway saw an investment ₹12,839 crore (US$1.5 billion) and was inaugurated on 9 August 2012 by then Chief Minister of UP Akhilesh Yadav. A total of 13 service roads of about 168 km were built for local commuters to access the expressway.
