There’s been a lot of discussion lately about what makes an active or vibrant streetscape, specifically as it related to the new Omni Hotel & Residences now approved on the old Water Company Block. And the suggestions about active streetscapes have ranged from adding benches, public art, and other pedestrian amenities, to ensuring a lively street wall with retail space and storefronts, to whether designer garage doors and fake retail can achieve the same thing.
Now there’s scientific evidence we can look at in making these decisions, fresh from Journal of Planning Education & Research. Researchers’ studied 20 different streetscape features in New York City—from street furnishings, facade activity, plazas, even building color—and then compared them to pedestrian counts on 588 blocks. The results, they say, are what most often attracts people to a place.
According to Next City‘s Josh Cohen, the study looks at the difference between “design elements [that] are bringing the crowds and which are just corollary.”
To study the public space elements, researchers created five overarching categories—”imageability (how memorable a street is), enclosure (the degree to which buildings enclosing the street make it feel room-like), human scale, transparency (the proportion of first-floor windows), and complexity,” according to Next City.
“New York is the most walkable city in the United States and it has a lot of the urban design qualities that we’re talking about,” Reid Ewing, a researcher at the University of Utah, told Cohen. “It represents kind of the best case in the U.S. for these urban design qualities and associated pedestrian traffic volumes.”
The result? Only three of the 20 streetscape design elements positively affected pedestrian activity, after controlling for density, diversity of land use, demographics, and destination accessibility. Cohen described the findings in his Next City post:
They are: the proportion of windows on the street, the amount of “active street frontage” and the quantity of street furniture. As is often the case with social science, the results help quantify some common-sense notions about urban design — in this instance, that people want interesting-looking streets at a human scale with places to go.
Windows are important for creating a welcoming interaction between people and buildings. Blank walls and reflective glass are boring and uninviting. Active street frontage — shops, restaurants, parks and similar — are critical for generating foot traffic. Ewing puts them in the category of imageability (how memorable the street is) and says memorable streets draw people. Street furniture such as benches, signs, lampposts and trash cans help keep the street at human scale.
“I would’ve expected more of the variables to be significant,” Ewing told Cohen. “They all sound pretty reasonable when you think of them: having courtyards, plazas, parks along a street. But the three variables that I proved to be significant are the only ones that are significant.” Or at least “statistically significant” to the study. “We’re not saying [other design elements] are not practically important. They’re just not statistically significant in our study,” Ewing added.
Ewing called for further study of public space design issues, and it would certainly make for an interesting research project to replicate in Louisville.
