The drift The Situationists were also practitioners of a special urban-analytic walking style, the dérive—the “drift”—which Debord described as “a technique of transient passage through varied ambiences. The dérive entails playful-constructive behavior and awareness of psychogeographical effects; which completely distinguishes it from the classical notions of the journey and the stroll.” “In a dérive,” Debord deadpans, “one or more persons during a certain period drop their usual motives for movement and action, their relations, their work and leisure activities, and let themselves be drawn by the attractions of the terrain and the encounters they find there." The dérive joins the free association of surrealism, the LSD of hippiedom, and cinematic montage as tactics for overcoming the fixity of received ideas of order and logic. By putting progress through the city into a state of constant indeterminacy, it represents a schooled “style” of being lost.

The axis of movement Moving in the city means constantly changing the axis of movement. In general, lateral movement is confined to a single plane, what’s called grade, the ground level. Because circulation in multistory buildings is fundamentally one way—which is to say from the bottom up—the condition at the top is invariably different from that at the bottom. Rooftop circulation is the domain of Fantômas, of cat burglars and fleeing criminals, of lovers, and of those acrobatic enough to negotiate the gaps between buildings.

Tactical urbanism Tactical urbanism includes low-cost, temporary changes to the built environment, usually in cities, intended to improve local neighborhoods and city gathering places. Tactical urbanism is also commonly referred to as guerrilla urbanism, pop-up urbanism, city repair, or D.I.Y. urbanism. The Street Plans Collaborative defines "tactical urbanism" as an approach to urban change that features the following five characteristics: A deliberate, phased approach to instigating change; The offering of local solutions for local planning challenges; Short-term commitment and realistic expectations; Low-risks, with a possibly high reward; and The development of social capital between citizens and the building of organizational capacity between public-private institutions, non-profits, and their constituents.
