journeys, developed in an integrated manner which enhances both the environment and quality of life of the surrounding area. These routes should meet satisfactory standards of width, gradient and surface condition to ensure that they are both user-friendly and low-risk for users of all abilities. (Lille Declaration, European Greenways Association, 12 September 2000). 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
