Greenway (landscape)
A greenway is usually a shared-use path along a strip of undeveloped land, in an urban or rural area, set aside for recreational use or environmental protection. Greenways are frequently created out of disused railways, canal towpaths, utility company rights of way, or derelict industrial land. Greenways can also be linear parks, and can serve as wildlife corridors. The path's surface may be paved and often serves multiple users: walkers, runners, bicyclists, skaters and hikers. A characteristic of greenways, as defined by the European Greenways Association, is "ease of passage": that is that they have "either low or zero gradient", so that they can be used by all "types of users, including mobility impaired people". In Southern England, the term also refers to ancient trackways or green lanes, especially those found on chalk downlands, like the Ridgeway. Definition 

Greenways are vegetated, linear, and multi-purpose. They incorporate a footpath and/or bikeway within a linear park. In urban design, they are a component of planning for bicycle commuting and walkability. The British organisation Sustrans, which is involved in creating cycleways and greenways, states that a traffic-free route "must be designed on the assumption that everyone will use it", and measures taken "to assist visually and mobility impaired users". The American author Charles Little in his 1990 book, Greenways for America, defines a greenway as:

The term greenway comes from the green in green belt and the way in parkway, implying a recreational or pedestrian use rather than a typical street corridor, as well as an emphasis on introducing or maintaining vegetation, in a location where such vegetation is otherwise lacking. Some greenways include community gardens as well as typical park-style landscaping of trees and shrubs. They also tend to have a mostly contiguous pathway. Greenways resemble linear parks, but the latter are only found in urban and suburban environments. The European Greenways Association defines it as 

Though wildlife corridors are also greenways, because they have conservation as their primary purpose, they are not necessarily managed as parks for recreational use, and may not include facilities such as public trails. Characteristics 

Charles Little in his 1990 book, Greenways for America", describes five general types of greenways:
  Urban riverside (or other water body) greenways, usually created as part of (or instead of) a redevelopment program along neglected, often run-down, city waterfronts. Recreational greenways, featuring paths and trails of various kinds, often relatively long distance, based on natural corridors as well as canals, abandoned rail beds, and public rights-of-way. Ecologically significant natural corridors, usually along rivers and streams and less often ridgelines, to provide for wildlife migration and species interchange, nature study and hiking. Scenic and Historic routes, usually along a road, highway or waterway, the most representative of them making an effort to provide pedestrian access along the route or at least places to alight from the car. Comprehensive greenway systems or networks, usually based on natural landforms such as valleys or ridges but sometimes simply an opportunistic assemblage of greenways and open spaces of various kinds to create an alternative municipal or regional green infrastructure. Greenways are found in rural areas as well as urban. Corridors redeveloped as greenways often travel through both city and country, connecting them together. Even in rural areas, greenways provide residents access to open land managed as parks, as contrasted with land that is vegetated but inappropriate for public use, such as agricultural land. Where the historic rural road network has been enlarged and redesigned to favor high-speed automobile travel, greenways provide an alternative for people who are elderly, young, less mobile or seeking a reflective pace.Loh et al. Tom Turner analyzed greenways in London looking for common patterns among successful examples. He was inspired by the pattern language technique of architect Christopher Alexander. A pattern language is an organized and coherent set of "patterns", each of which describes a problem and the core of a solution that can be used in many ways within a specific field of expertise. Turner concluded there are seven types, or 'patterns', of greenway which he named: 
parkway: a landscaped thoroughfare. The term is particularly used for a roadway in a park or connecting to a park from which trucks and other heavy vehicles are excluded. blueway: a water trail
paveway: an upgraded pavement or sidewalk: "Well-designed paveways, with appropriate planting and street furniture, should be formed along main pedestrian desire lines". glazeway: a glazed passage linking buildings. Turner argues for their greater use in cities. skyway, skybridge, or skywalk is an elevated type of pedway connecting two or more buildings in an urban area, or connecting elevated points within mountainous recreational zones. ecoway: linked green spaces or green corridor, including household gardens in a city. cycleway. Foreshoreway

In Australia, a foreshoreway (or oceanway) is a greenway that provides a public right-of-way along the edge of the sea, open to both walkers and cyclists. Foreshoreways resemble promenades and boardwalks. Foreshoreways are usually concerned with the idea of sustainable transport. A foreshoreway is accessible to both pedestrians and cyclists and gives them the opportunity to move unimpeded along the seashore. Dead end paths that offer public access only to the ocean are not part of a foreshoreway. A foreshoreway corridor often includes a number of traffic routes that provide access along an oceanfront, including:
 walking along the beach
 edge of foreshore off-road greenway
 edge of road off-road greenway
 on road bikeway
 on road private vehicles routes
 on road public transport corridor

A major example is The Gold Coast Oceanway along beaches in Gold Coast, Queensland, a shared use pedestrian and cyclist pathway on the Gold Coast, connecting the Point Danger lighthouse on the New South Wales and Queensland border to the Gold Coast Seaway. The network includes  of poor, medium and high quality pathways. Others include: The Chicago Lakefront Trail, the Dubai Marina, the East River Greenway, New Plymouth Coastal Walkway, and the Manhattan Waterfront Greenway. Public rights of way frequently exist on the foreshore of beaches throughout the world. In legal discussions the foreshore is often referred to as the wet-sand area (see Right of way for a fuller discussion). Linear park 
A linear park is a park in an urban or suburban setting that is substantially longer than it is wide. Some are rail trails ("rails to trails"), that are disused railroad beds converted to recreational use, while others use strips of public land next to canals, streams, extended defensive walls, electrical lines, highways and shorelines. They are also often described as greenways.City of Kelowna, British Columbia, Canada In Australia, a linear park along the coast is known as a foreshoreway. Examples
