Urban Air Mobility

MVRDV is developing a plan for the future of Urban Air Mobility (UAM). The investigation tackles the integration of “flying vehicles” into our urban environments and envisions a comprehensive mobility concept. Addressing major questions like “How will these flying vehicles impact our urban environments? And how could they be leveraged to improve our cities?” MVRDV and Airbus are exploring the possibility of reconnecting territories through an accessible-for-all system. Avoiding the negative impact that comes with the introduction of new transportation modes into cities, the study imagines both short-term and long-term scenarios, in order to dodge any detrimental impacts from this disruptive technology.

AR Urbanism

What does the virtual space that “belongs to us” look like? Would could it look like? We might imagine a future as steeped in AR as Matsuda’s Hyperreality, but where instead of a hybrid landscape dominated by ads and obfuscating distractions, augmented overlays are used to highlight the hidden dimensions of place, or serve as a distinctly spatial platform for alternative forms of communication and culture. Inverting the vision of a commodified hybrid landscape, the seemingly inevitable barrage of immersive, interfacial capitalism could perhaps be transmuted into something democratic, artful, and even beautiful: a conduit to mobile urban discourse and learning; to collectively owned and managed hybrid spaces, and to community as a social body intersecting physical and digital worlds. But if this more hopeful image of an AR-saturated future is to come to fruition, it will require a deeply collaborative spirit between programmers and urbanists, artists and technologists, activists and educators — and most certainly architects as well.

Gentrification Is in the Stars

You know it when you see it, or perhaps smell it. Gentrification is that new dog park. It’s the Starbucks on the corner, the yoga studio, and the gradual rise in police presence. But it’s surprisingly hard to track the exact moment when a critical mass of more affluent people move into a neighborhood and tip property values up—the simplest, if not the most universally agreed upon, definition of the “G” word. Traditional public data sources can fail to pick up the rapid transformation that can occur in a community, since their records are usually updated on multi-year cycles. And government registries usually catalogue businesses in broad categories—you’re not going to find artisanal donut parlors or motorcycle lifestyle shops grouped together by the Census Bureau. A new working paper shows how review data can be used to quantify and track neighborhood change, putting a hard spine on what can otherwise be a soft science. Matching up a massive trove of business and service listings from the uber-popular reviews site against changes in housing prices and demographics, they found that reviews appears to work as a real-time forecaster of neighborhood change. You just have to look at the right types of listings.

Vacant Property Theory

Broken-windows theory always worked better as an idea than as a description of the real world. The problems with the theory, which include the fact that perceptions of disorder generally have more to do with the racial composition of a neighborhood than with the number of broken windows or amount of graffiti in the area, are numerous and well documented. But more interesting than the theory’s flaws is the way that it was framed and interpreted. Consider the authors’ famous evocation of how disorder begins: A piece of property is abandoned, weeds grow up, a window is smashed. Adults stop scolding rowdy children; the children, emboldened, become more rowdy. Families move out, unattached adults move in. Teenagers gather in front of the corner store. The merchant asks them to move; they refuse. Fights occur. Litter accumulates. People start drinking in front of the grocery; in time, an inebriate slumps to the sidewalk and is allowed to sleep it off. Pedestrians are approached by panhandlers. Things get worse from there. But what’s curious is how the first 2 steps of this cycle—“A piece of property is abandoned, weeds grow up”—have disappeared in the public imagination. The 3rd step—“a window is smashed”—inspired the article’s catchy title and took center stage. Debates about the theory ignored the 2 problems at the root of its story, jumping straight to the criminal behavior. We got “broken windows,” not “abandoned property,” and a very different policy response ensued. But what if the authors—and the policymakers who heeded them—had taken another tack? What if vacant property had received the attention that, for 30 years, was instead showered on petty criminals?

4x Wealth from Global City

There were time and motion studies in the early 20th century which found that if a city could have 2x the population then productivity would increase and per person income would increase by 7%. Currently the world is 56% urbanized. Only 10% are in megacities with population over 10m. 100% urbanization would 2x world GDP with increased productivity. Another 30% boost in productivity would come from having everyone in megacities.

Urban Revitalization Factors

the system compared 1.6M pairs of photos taken 7 years apart to test several hypotheses about the causes of urban revitalization. Density of highly educated residents, proximity to central business districts and other physically attractive neighborhoods, and the initial safety score assigned by the system all correlate strongly with improvements in physical condition. Raw income levels, housing prices or neighborhoods’ ethnic makeup do not to predict change.
