Tactical urbanism, also commonly referred to as guerrilla urbanism, pop-up urbanism, city repair, D.I.Y. urbanism, [1] planning-by-doing, urban acupuncture, and urban prototyping, [2] is a low-cost, temporary change to the built environment, usually in cities, intended to improve local neighbourhoods and city gathering places. [3]
Tactical urbanism is often citizen-led but can also be initiated by government entities. Community-led temporary installations are often intended to pressure government agencies into installing a more permanent or expensive version of the improvement. [4]
The term was popularized around 2010 to refer to a range of existing techniques. The Street Plans Collaborative defines "tactical urbanism" as an approach to urban change that features the following five characteristics: [1]
While the 1984 English translation of The Practice of Everyday Life by French author Michel de Certeau used the term tactical urbanism, [5] this was in reference to events occurring in Paris in 1968; the "tactical urbanism" that Certeau described was in opposition to "strategic urbanism", which modern concepts of tactical urbanism tend not to distinguish. The modern sense of the term is attributed to New York-based urban planner Mike Lydon. [6]
The Project for Public Spaces uses the phrase "Lighter, Quicker, Cheaper", coined by urban designer Eric Reynolds, to describe the same basic approach expressed by tactical urbanism. [7]
The tactical urbanist movement takes inspiration from urban experiments including Ciclovía, Paris-Plages, [8] and the introduction of plazas and pedestrian malls in New York City during the tenure of Janette Sadik-Khan as Commissioner of the New York City Department of Transportation. [9]
Tactical urbanism formally emerged as a movement following a meeting of the Next Generation of New Urbanist (CNU NextGen) group in November 2010 in New Orleans. A driving force of the movement is to put the onus back on individuals to take personal responsibility in creating sustainable buildings, streets, neighborhoods, and cities. Following the meeting, an open-source project called Tactical Urbanism: Short TermAction | Long Term Change was developed by a group from NextGen to define tactical urbanism and to promote various interventions to improve urban design and promote positive change in neighbourhoods and communities. [10]
Honolulu, Hawaii has some of the highest pedestrian fatality rates in the United States (Wong 2012).[ citation needed ] Many of their busiest intersections reflect city standards from years past without modification as the quantity of vehicular traffic and associated speeds have changed dramatically. Some residents chose to take a stand in 2014. Within the crosswalk of one of these busy intersections, residents altered the crosswalk lines so that they spelled out "Aloha," the traditional Hawaiian salutation. While the perpetrators sought to introduce a level of humanity to the dangerous location, city officials stated that the change was a "deviation from the standard." [11]
In spring of 2016, the city of Chicago posted unique "no right turn" signage to an intersection. To call attention to this new condition, an unknown person installed two small planter boxes within the crosswalk with flowering plants. Many responded positively while local businesses expressed concern for the traffic pattern change and its effect on their business. [12]
Tactical urbanism projects vary significantly in scope, size, budget, legality, and support. Projects often begin as grassroots interventions and spread to other cities, and are in some cases later adopted by municipal governments as best practices. Some common interventions are listed below:
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 curb. There may also be a planted strip between the sidewalk and the roadway and between the roadway and the adjacent land.
A pedestrian crossing is a place designated for pedestrians to cross a road, street or avenue. The term "pedestrian crossing" is also used in the Vienna and Geneva Conventions, both of which pertain to road signs and road traffic.
New Urbanism is an urban design movement that promotes environmentally friendly habits by creating walkable neighbourhoods containing a wide range of housing and job types. It arose in the United States in the early 1980s, and has gradually influenced many aspects of real estate development, urban planning, and municipal land-use strategies. New Urbanism attempts to address the ills associated with urban sprawl and post-WW II suburban development.
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.
In economics, induced demand – related to latent demand and generated demand – is the phenomenon whereby an increase in supply results in a decline in price and an increase in consumption. In other words, as a good or service becomes more readily available and mass produced, its price goes down and consumers are more likely to buy it, meaning that the quantity demanded subsequently increases. This is consistent with the economic model of supply and demand.
A curb extension is a traffic calming measure which widens the sidewalk for a short distance. This reduces the crossing distance and allows pedestrians and drivers to see each other when parked vehicles would otherwise block visibility. The practice of banning car parking near intersections is referred to as daylighting the intersection.
A bus bulb, also called a bus boarder, bus border, bumpout, bus cape, or a kerb outstand is an arrangement by which a sidewalk or pavement is extended outwards for a bus stop; typically the bus bulb replaces roadway that would otherwise be part of a parking lane. With bus bulbs or boarders, a bus can stay in its traffic lane to discharge and pick up passengers, instead of having to pull over to the curb.
A woonerf is a living street, as originally implemented in the Netherlands and in Flanders (Belgium). Techniques include shared space, traffic calming, and low speed limits.
A living street is a street designed with the interests of pedestrians and cyclists in mind. 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.
Bike lanes (US) or cycle lanes (UK) are types of bikeways (cycleways) with lanes on the roadway for cyclists only. In the United Kingdom, an on-road cycle-lane can be firmly restricted to cycles or advisory. In the United States, a designated bicycle lane or class II bikeway (Caltrans) is always marked by a solid white stripe on the pavement and is for 'preferential use' by bicyclists. There is also a class III bicycle route, which has roadside signs suggesting a route for cyclists, and urging sharing the road. A class IV separated bike way (Caltrans) is a bike lane that is physically separate from motor traffic and restricted to bicyclists only.
William Hollingsworth "Holly" Whyte Jr. was an American urbanist, sociologist, organizational analyst, journalist and people-watcher. He identified the elements that create vibrant public spaces within the city and filmed a variety of urban plazas in New York City in the 1970s. After his book about corporate culture The Organization Man (1956) sold over two million copies, Whyte turned his attention to the study of human behavior in urban settings. He published several books and a film on the topic, including The Social Life of Small Urban Spaces (1980).
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. 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, road markings are conceived as horizontal traffic signs, as opposed to vertical traffic signs placed on posts.
Ciclovía, also ciclovia or cyclovia, is a Spanish term that means "cycleway", either a permanent bike path or the temporary closing of certain streets to automobiles for cyclists and pedestrians, a practice sometimes called open streets.
A road diet is a technique in transportation planning whereby the number and/or the width of travel lanes of the road is reduced to calm traffic and achieve proven benefits, including a statistically attested crash reduction rate of 19% to 47%.
Complete streets is a transportation policy and design approach that requires streets to be planned, designed, operated and maintained to enable safe, convenient and comfortable travel and access for users of all ages and abilities regardless of their mode of transportation. Complete Streets allow for safe travel by those walking, cycling, driving automobiles, riding public transportation, or delivering goods.
The Culver Boulevard Median Bike Path is Class I rail trail bicycle path, walk route and linear park on Culver Boulevard in western Los Angeles County, California.
In the United States, road signs are, for the most part, standardized by federal regulations, most notably in the Manual on Uniform Traffic Control Devices (MUTCD) and its companion volume the Standard Highway Signs (SHS).
A parklet is a sidewalk extension that provides more space and amenities for people using the street. Usually parklets are installed on parking lanes and use several parking spaces. Parklets typically extend out from the sidewalk at the level of the sidewalk to the width of the adjacent parking space.
A guerrilla crosswalk is a pedestrian crossing that has been modified or created without jurisdictional approval, and with the intent of improving pedestrian and other non-automobile safety. These interventions are a common strategy within tactical urbanism, a type of low-cost, often temporary change to the built environment intended to improve local livability. Guerilla crosswalks have been noted in news articles since at least 2009 and have become more well known as an urban strategy in recent years. The first known example of guerilla crosswalks can be found in Canada in 1987 when social activists John Valeriote and Erik Veldman created a crosswalk in Guelph, Ontario for students to safely cross a busy road in front of their school.
A stroad is a type of street–road hybrid. Common in the United States and Canada, stroads are wide arterials that often provide access to strip malls, drive-throughs, and other automobile-oriented businesses. Stroads have been criticized by urban planners for their safety issues and inefficiencies. While streets serve as a destination and provide access to shops and residences at safe traffic speeds, and roads serve as a high-speed connection that can efficiently move traffic at high speed and volume, stroads are often expensive, inefficient, and dangerous.

ignored (help)As Bellingham elected officials and traffic engineers are deciding where to prioritize transportation projects such as roads, bike lanes and sidewalks over the next several years, some residents are seeking a speedier remedy. They're trying to goose the bureaucracy into taking quick action to slow the commuters ... To get the city's attention earlier this year, about 50 Columbia residents spent a few hours building a pair of DIY crosswalks, using colored chalk and some traffic cones, materials that cost about $200
There's a name for when community members make unsanctioned changes to city-owned streets: "tactical urbanism."
