In urban planning, the grid plan, grid street plan, or gridiron plan is a type of city plan in which streets run at right angles to each other, forming a grid.
Traffic calming uses physical design and other measures to improve safety for motorists, pedestrians and cyclists. It has become a tool to combat speeding and other unsafe behaviours of drivers in the neighbourhoods. It aims to encourage safer, more responsible driving and potentially reduce traffic flow. Urban planners and traffic engineers have many strategies for traffic calming, including narrowed roads and speed humps. Such measures are common in Australia and Europe, but less so in North America. Traffic calming is a calque of the German word Verkehrsberuhigung – the term's first published use in English was in 1985 by Carmen Hass-Klau.
A street is a public thoroughfare in a built environment. It is a public parcel of land adjoining buildings in an urban context, on which people may freely assemble, interact, and move about. A street can be as simple as a level patch of dirt, but is more often paved with a hard, durable surface such as tarmac, concrete, cobblestone or brick. Portions may also be smoothed with asphalt, embedded with rails, or otherwise prepared to accommodate non-pedestrian traffic.
Bicycle-friendly policies and practices help some people feel more comfortable about traveling by bicycle with other traffic. The level of bicycle-friendliness of an environment can be influenced by many factors including town planning and cycling infrastructure decisions. A stigma towards people who ride bicycles and fear of cycling is a social construct that needs to be fully understood when promoting a bicycle friendly culture.
Road traffic safety refers to the methods and measures used to prevent road users from being killed or seriously injured. Typical road users include pedestrians, cyclists, motorists, vehicle passengers, and passengers of on-road public transport.
Utility cycling encompasses any cycling done simply as a means of transport rather than as a sport or leisure activity. It is the original and most common type of cycling in the world. Cycling mobility is one of the various types of private transport and a major part of individual mobility.
A dead end, also known as a cul-de-sac, no through road or no exit road, is a street with only one inlet or outlet.
A city block, residential block, urban block, or simply block is a central element of urban planning and urban design.
A living street is a street designed with the interests of pedestrians and cyclists in mind by providing enriching and experiential spaces. Living streets also act as social spaces, allowing children to play and encouraging social interactions on a human scale, safely and legally. Living streets consider all pedestrians granting equal access to elders and those who are disabled. These roads are still available for use by motor vehicles; however, their design aims to reduce both the speed and dominance of motorized transport. The reduction of motor vehicle dominance creates more opportunities for public transportation.
The street hierarchy is an urban planning technique for laying out road networks that exclude automobile through-traffic from developed areas. It is conceived as a hierarchy of roads that embeds the link importance of each road type in the network topology. Street hierarchy restricts or eliminates direct connections between certain types of links, for example residential streets and arterial roads, and allows connections between similar order streets or between street types that are separated by one level in the hierarchy. By contrast, in many regular, traditional grid plans, as laid out, higher order roads are connected by through streets of both lower order levels. An ordering of roads and their classification can include several levels and finer distinctions as, for example, major and minor arterials or collectors.
A carfree city is an urban area absent of motor vehicles. Carfree cities rely on public transport, walking, and cycling for travel as opposed to motor vehicles. Districts where motor vehicles are prohibited are referred to as carfree zones. Carfree city models have gained traction in the second half of the 20th century due to issues with congestion and infrastructure, and proposed environmental and quality of life benefits. Many cities in Asia, Europe, and Africa have carfree areas due to the cities being created before the invention of motor vehicles, while many developing cities in Asia are using the carfree model to modernize their infrastructure.
The fused grid is a street network pattern first proposed in 2002 and subsequently applied in Calgary, Alberta (2006) and Stratford, Ontario (2004). It represents a synthesis of two well known and extensively used network concepts: the "grid" and the "Radburn" pattern, derivatives of which are found in most city suburbs. Both concepts were conscious attempts to organize urban space for habitation. The grid was conceived and applied in the pre-automotive era of cities starting circa 2000 BC and prevailed until about 1900 AD. The Radburn pattern emerged in 1929 about thirty years following the invention of the internal combustion engine powered automobile and in anticipation of its eventual dominance as a means for mobility and transport. Both these patterns appear throughout North America. "Fused" refers to a systematic recombination of the essential characteristics of each of these two network patterns.
In England and Wales, the Manual for Streets, published in March 2007, provides guidance for practitioners involved in the planning, design, provision and approval of new streets, and modifications to existing ones. It aims to increase the quality of life through good design which creates more people-oriented streets. Although the detailed guidance in the document applies mainly to residential streets, the overall design principles apply to all streets within urban areas.
A pedestrian village is a compact, pedestrian-oriented neighborhood or town with a mixed-use village center. Shared-use lanes for pedestrians and those using bicycles, Segways, wheelchairs, and other small rolling conveyances that do not use internal combustion engines. Generally, these lanes are in front of the houses and businesses, and streets for motor vehicles are always at the rear. Some pedestrian villages might be nearly car-free with cars either hidden below the buildings, or on the boundary of the village. Venice, Italy is essentially a pedestrian village with canals. Other examples of a pedestrian village include Giethoorn village located in the Dutch province of Overijssel, Netherlands, Mont-Tremblant Pedestrian Village located beside Mont-Tremblant, Quebec, Canada, and Culdesac Tempe in Tempe, Arizona.
Honeycomb housing is an urban planning model pertaining to residential subdivision design.
Vauban is a neighbourhood (Stadtteil) to the south of the town centre in Freiburg, Germany. It was built as "a sustainable model district" on the site of a former French military base named after Sébastien Le Prestre de Vauban, the 17th century French Marshal who built fortifications in Freiburg while the region was under French rule. Construction began in 1998, and the first two residents arrived in 2001.
The sustainable urban neighbourhood (SUN) is an urban design model which is part of 21st-century urban reform theory, moving away from the typical suburban development of the UK and US towards more continental city styles. It emerged in the UK in the 1990s, specifically from pioneering work by URBED, an urban regeneration consultancy and research centre in Manchester.
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.
A modal filter, sometimes referred to as a point closure, is a road design that restricts the passage of certain types of vehicle. Modal filtering is often used to help create a low traffic neighbourhood (LTN), where motor traffic is diverted away from residential streets and instead toward feeder roads. Modal filters can be used to achieve filtered permeability within a transport network, and can encourage walking and cycling through more pleasant environments and improved safety.
In the United Kingdom, a Low Traffic Neighbourhood (LTN) is an area in which filtered permeability and traffic calming are deployed to reduce motorised through-traffic in residential areas. Many LTNs were introduced in spring 2020, although the same principles had been in use in London since the 1970s.
