A desire path, often referred to as a desire line in transportation planning and also known by various other names, [lower-alpha 1] is an unplanned small trail created as a consequence of mechanical erosion caused by human or animal traffic. The path usually represents the shortest or the most easily navigated route between an origin and destination, and the width and severity of its surface erosion are often indicators of the traffic level it receives.
An early documented example is Broadway in New York City, which follows the Wecquaesgeek trail which predates American colonization. [1]
Desire paths typically emerge as convenient shortcuts where more deliberately constructed paths take a longer or more circuitous route, have gaps, or are non-existent. Once a path has been trodden out through the natural vegetation, subsequent traffic tends to follow that visibly existing route (as it is more convenient than carving out a new path by oneself), and the repeated trampling will further erode away both the remaining groundcover and the soil quality that allows easy revegetation. Eventually, a clearly visible and easily passable path emerges that humans and animals alike tend to prefer.
Desire paths sometimes cut through sensitive habitats and exclusion zones, threatening wildlife and park security. However, they also provide park management with an indicator of activity concentration. In Yosemite National Park, the National Park Service uses these indicators to help guide its management plan. [2]
Trampling studies have consistently documented that impacts on soil and vegetation occur rapidly with initial use of desire paths. As few as 15 passages over a site can be enough to create a distinct trail, the existence of which then attracts further use. [3] : 27 This finding contributed to the creation of the Leave No Trace education program, which instructs travelers in nature areas to either stay on designated trails or, when off trail, distribute their travel lines so as to not inadvertently create new trails in unsustainable locations. [4]
Land managers have devised a variety of techniques to block the creation of desire paths, including fences, dense vegetation, and signage, though none are foolproof. Modern trail design attempts to avoid the need for barriers and restrictions, by aligning trail layout and user desire through physical design and persuasive outreach. [3] : 16
Landscapers sometimes accommodate desire paths by paving them, thereby integrating them into the official path network rather than blocking them. [5] [6] Sometimes, land planners have deliberately left land fully or partially unpathed, waiting to see what desire paths are created, and then paving those. [5] In Finland, planners are known to visit parks immediately after the first snowfall, when the existing paths are not visible. [7] [8] The naturally chosen desire paths, marked by footprints, can then be used to guide the routing of new purpose-built paths. [7]
Images of desire paths have been employed as a metaphor for anarchism, intuitive design, individual creativity, and the wisdom of crowds. [9] [10] [11] [12] [13] [14]
In urban planning, desire paths have been used to analyze traffic patterns for a given mode of travel. For example, the 1959 Chicago Area Transportation Study used desire paths to illustrate commuter choices regarding railroad and subway trips. [15]
In software design, the term is used to describe users' wide adoption of the same methods to overcome limitations in the software. [16] For example, X (Twitter) "paved" a number of desire paths by integrating them into the service, including @ replies, hashtags, and group discussions. [17] [18]
A road is a thoroughfare for the conveyance of traffic that mostly has an improved surface for use by vehicles and pedestrians. Unlike streets, whose primary function is to serve as public spaces, the main function of roads is transportation.
A sidewalk, pavement, footpath in Australia, India, New Zealand and Ireland, or footway is a path along the side of a road. Usually constructed of concrete, pavers, brick, stone, or asphalt, it is designed for pedestrians. A sidewalk is normally higher than the roadway, and separated from it by a kerb. There may also be a planted strip between the sidewalk and the roadway and between the roadway and the adjacent land.
A trail, also known as a path or track, is an unpaved lane or a small paved road not intended for usage by motorized vehicles, usually passing through a natural area. In the United Kingdom and Ireland, a path or footpath is the preferred term for a pedestrian or hiking trail. The term is also applied in North America to accompanying routes along rivers, and sometimes to highways. In the US, the term was historically used for a route into or through wild territory used by explorers and migrants. In the United States, "trace" is a synonym for trail, as in Natchez Trace.
The Marriott's Way is a footpath, cycle-path and bridleway in north Norfolk, England, between Norwich and Aylsham via Themelthorpe. It forms part of the National Cycle Network (NCN) and the red route of Norwich's Pedalways cycle path network. It is open to walkers, cyclists and horse riders. Its total length is 24.6 miles (39.5 km). It has a mixture of surfaces: tarmac, compacted gravel and earth. The name of the route originates from the chief engineer and manager of the Midland and Great Northern Joint Railway (M&GNJR), William Marriott, who held the position for 41 years.
A parkway is 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.
A pedestrian is a person traveling on foot, whether walking or running. In modern times, the term usually refers to someone walking on a road or pavement, but this was not the case historically. Pedestrians may also be wheelchair users or other disabled people who use mobility aids.
A rail trail is a shared-use path on railway right of way. Rail trails are typically constructed after a railway has been abandoned and the track has been removed but may also share the right of way with active railways, light rail, or streetcars, or with disused track. As shared-use paths, rail trails are primarily for non-motorized traffic including pedestrians, bicycles, horseback riders, skaters, and cross-country skiers, although snowmobiles and ATVs may be allowed. The characteristics of abandoned railways—gentle grades, well-engineered rights of way and structures, and passage through historical areas—lend themselves to rail trails and account for their popularity. Many rail trails are long-distance trails, while some shorter rail trails are known as greenways or linear parks.
Vehicular cycling is the practice of riding bicycles on roads in a manner that is in accordance with the principles for driving in traffic. The phrase vehicular cycling was coined by John Forester in the 1970s. In his book Effective Cycling, Forester contends that "Cyclists fare best when they act and are treated as drivers of vehicles".
Bicycle transportation planning and engineering are the disciplines related to transportation engineering and transportation planning concerning bicycles as a mode of transport and the concomitant study, design and implementation of cycling infrastructure. It includes the study and design of dedicated transport facilities for cyclists as well as mixed-mode environments and how both of these examples can be made to work safely. In jurisdictions such as the United States it is often practiced in conjunction with planning for pedestrians as a part of active transportation planning.
The Grand Junction Railroad is an 8.55-mile (13.76 km) long railroad in the Boston, Massachusetts, area, connecting the railroads heading west and north from Boston. The line is notable for its railroad bridge over the Charles River that passes under the Boston University Bridge between Boston and Cambridge, Massachusetts.
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".
A bridle path, also bridleway, equestrian trail, horse riding path, ride, bridle road, or horse trail, is a trail or a thoroughfare that is used by people riding on horses. Trails originally created for use by horses often now serve a wider range of users, including equestrians, hikers, and cyclists. Such paths are either impassable for motorized vehicles, or vehicles are banned. The laws relating to allowable uses vary from country to country.
Tactile paving is a system of textured ground surface indicators found at roadsides, by and on stairs, and on railway station platforms, to assist pedestrians who are vision impaired.
The Springwater Corridor Trail is a bicycle and pedestrian rail trail in the Portland metropolitan area in Oregon, United States. It follows a former railway line from Boring through Gresham to Portland, where it ends south of the Eastbank Esplanade. Most of the corridor, about 21 miles (34 km) long, consists of paved, off-street trail, though about 1 mile (1.6 km) overlaps city streets in Portland's Sellwood neighborhood. A large segment roughly follows the course of Johnson Creek and crosses it on bridges many times. Much of the corridor was acquired by the City of Portland in 1990; remaining segments were acquired by Metro thereafter.
The Virginia Capital Trail (VCT) (informally, the Cap Trail, or simply the Cap) is a dedicated, paved bicycle and pedestrian trail crossing four counties and 51.7 miles (83.2 km) between Jamestown and Richmond, Virginia — that is, between the Colony of Virginia's first capital and Virginia's current capital.
A site plan or a plot plan is a type of drawing used by architects, landscape architects, urban planners, and engineers which shows existing and proposed conditions for a given area, typically a parcel of land which is to be modified. Sites plan typically show buildings, roads, sidewalks and paths/trails, parking, drainage facilities, sanitary sewer lines, water lines, lighting, and landscaping and garden elements.
Cycling in Canada is experienced in various ways across a geographically huge, economically and socially diverse country. Among the reasons for cycling in Canada are for practical reasons such as commuting to work or school, for sports such as road racing, BMX, mountain bike racing, freestyle BMX, as well as for pure recreation. The amount and quality of bicycle infrastructure varies widely across the country as do the laws pertaining to cyclists such as bicycle helmet laws which can differ by province.
Cycling infrastructure is all infrastructure cyclists are allowed to use. Bikeways include bike paths, bike lanes, cycle tracks, rail trails and, where permitted, sidewalks. Roads used by motorists are also cycling infrastructure, except where cyclists are barred such as many freeways/motorways. It includes amenities such as bike racks for parking, shelters, service centers and specialized traffic signs and signals. The more cycling infrastructure, the more people get about by bicycle.
A shared-use path, mixed-use path or multi-use pathway is a path which is "designed to accommodate the movement of pedestrians and cyclists". Examples of shared-use paths include sidewalks designated as shared-use, bridleways and rail trails. A shared-use path typically has a surface that is asphalt, concrete or firmly packed crushed aggregate. Shared-use paths differ from cycle tracks and cycle paths in that shared-use paths are designed to include pedestrians even if the primary anticipated users are cyclists.
The Vancouver Greenway Network is a collection of greenways across Vancouver, British Columbia, Canada. Greenways are streets where pedestrians and cyclists are prioritized over motorized vehicles, through structures such as road closures and road diverters to prevent or limit motor vehicle traffic, widened sidewalk-promenades, narrowed road space, speed restrictions, bike lanes, raised sidewalks and speed bumps. The City of Vancouver hopes to create and maintain the trend of constructing new greenways to establish a network where, potentially, every citizen could access a city greenway within a 25-minute walking or a 10-minute cycling distance of their home.
