How parking infrastructure reveals a region's values

Smart cities have been more successful when upgrading existing infrastructure

Building urban landscapes with smart technologies from scratch has sometimes produced futuristic-looking yet sterile environments that struggle to attract residents and justify high costs. Enhancing existing areas while retaining their historical and cultural touchstones has proven more appealing in many cities.

A sociologist makes the case for libraries and parks as essential public infrastructure

Eric Klinenberg argues that social infrastructure that brings people together is as vital to a community as roads or power grids. He contends that when communities invest in these spaces, residents grow more connected, and when they are neglected, isolation follows.

Why are ancient ruins underground?

When cities fall into disrepair, it's often easier to flatten what you can and build on top. This is why modern archaeologists frequently discover ruins underground, revealing generational layers of cities rebuilt over time. This video explores major examples of this principle, from ancient Troy to even modern Seattle.

Dubai and Barcelona are examples of smart cities

By integrating technology into public transit, utilities, and other municipal systems, these cities aim to reduce costs and enhance the quality of life for their residents. Some of these technologies include adaptive lighting, parking sensors, and underground waste systems.

Why some US cities pay thousands of dollars for a single public trash can

The rationale supposes high-end, heavy-duty trash cans reduce litter and maintenance costs, justifying per-unit costs of close to $3,000 in some municipalities. But results are mixed, and some experiments using cheap 55-gallon drums were similarly effective.

Zoning laws determine what can be built—and where—in every American community

Local governments use zoning to regulate land use. About 75% of residentially zoned land in American cities is designated for single-family homes only—a restriction that some experts blame for increasing housing costs and reducing affordability.

The 'Gruen transfer' refers to the price psychology behind large shopping malls, where shoppers make spontaneous purchases due to the overwhelming exposure to a variety of stores.

How congestion pricing is trying to fix downtowns

Billions of gallons of gas are wasted each year as US drivers sit in traffic losing billions of hours of time. The congestion problems big downtowns face has led to innovative interventions to try to stop the traffic, including congestion pricing, a...

Cities and parks often work to prevent graffiti

Although some call it art, many see it as an eyesore and try to prevent it through prohibitive designs, lighting, and vandal-proofed coatings that make spray paint easier to remove. This guide from the Project for Public Spaces outlines some of those strategies and more.

NYC congestion pricing a year in: traffic is down, transit is up

Manhattan's congestion pricing program has quietly become a success story. WNYC reporter Stephen Nessen examines why the original backlash to the concept has faded, how New Yorkers adjusted, and what the city's experience shares with similar policies in Stockholm and London.

Washington DC's streetcar network built the modern American suburb

Washington's first electric streetcar line launched in 1888, and real estate developers quickly built lines to open new neighborhoods. A 35-minute ride from Chevy Chase, Maryland, to downtown Washington transformed farmland into a suburb.

Self-driving cars may upend transit before cities can build it

Austin approved a $7.1B light-rail in 2020, but components of the plan have already been cut. Simultaneously, Waymo launched a 200-car autonomous fleet across the city. Cities now face a choice: invest in decadeslong fixed infrastructure projects or embrace flexible, on-demand autonomous vehicles that can navigate anywhere.

45% of Americans have no access to public transit

Most US transit was built on a monocentric design, funneling riders into a downtown center. But today's most common commute is from suburb to suburb, meaning the system is built for a work pattern that no longer exists.

Why Amsterdam looks so unique

The Netherlands' capital consists of concentric canals lined with towering, unusually thin row homes, an altogether unique profile in Europe and the world. When it was growing, the city was a key trade hub, and merchants wanted direct access to waterways. Canals were built like roads, and houses were required to be very thin to allow for more homes to line the canals.

Imagining the nostalgia we'll feel one day for gas stations

Car drivers everywhere are accustomed to an endless array of gas stations along the road, with their high, flat roofs, convenience stores of varying quality, and bathroom availability. Current trends in electric vehicle development point to such stations' inevitable obsolescence, and one photographer has begun documenting neglected filling stations in transit-oriented Germany. See the images for yourself and begin the journey toward so-called petronostalgia.

Urban planning in ancient Rome

Ancient Rome represents one of the earliest examples of coordinated urban planning from a central government for which researchers have access to contemporary records. This review from MIT showcases ancient Roman cities built on various types of grids, from rectangular outlines to those shaped around two intersecting axes, with several examples and maps provided for each.

Hear about the debate over free public transportation

Free public transit boosts economic opportunity and social mobility and is better for the environment. So why do we charge for it? Opponents of free transit cite revenue losses threatening service quality and data showing that free fares don't translate into reduced car use.

The hidden engineering of gas stations

Contemporary gas stations are the result of a century of engineering progress. In the early 1900s, only a few thousand cars drove around, and they used kerosene. As vehicles and cheaper gasoline became more popular, fire hazards grew, forcing the invention of fuel pumps, underground storage tanks, and the automatic shutoff valve—all engineering marvels.

In the '70s, graffiti moved to subway cars

Unlike static walls, the silver cars moved throughout the city, like a canvas in perpetual motion. That made them highly desired by graffiti artists, especially because tagging them was considerably more difficult and, in turn, more impressive than a simple tag in an alley.

In 2024, US airports generated over $1B of revenue—partly due to overpriced airport food

Some in the airport industry argue that charging street prices in airport restaurants isn't sustainable because it's more expensive to run a business inside an airport.

Connected technology improves infrastructure efficiency in smart cities

Through information and communication technologies, smart cities can provide enhanced public services and improved quality of life by managing traffic and dynamic safety policies. They can also promote sustainability by automating energy use and redirecting resources according to need.

Abandoned Detroit: the decline of America's car mecca

Detroit, Michigan, began as a fur trading post in the 1700s but would become the world epicenter of car manufacturing in the 1900s after Henry Ford developed his paradigm-shifting assembly line at a plant there. Racial tensions, a lack of economic diversification, and poor leadership would plunge the city into poverty and decay in the late 1900s, culminating in a 2014 bankruptcy. Browse the somber images of the city's abandoned spaces here.

An exploration of the life and death of US malls

American malls sought to recreate the cohesion of a downtown shopping center but with the indoor, quiet convenience of a rural or suburban setting. First developed in the 1950s, malls quickly took off and became the spine of American retail shopping. In the last two decades, online retail has forced many to close, leaving behind peculiar, vast abandoned spaces. Pick through the stark nostalgia with this fascinating photo essay.

NFL stadiums are designed to maximize profit, not number of seats

Most stadiums are actually getting smaller as the cost of land rises. Owners have sought to increase returns by designing prestige suits and clubs (rather than just more general admission) and laying out the stadium to maximize customer purchases.

The theory behind public art

Proponents of public art, including graffiti, argue that its free access and visibility breaks down the elitism and financial barriers of galleries and museums, allowing people to interact or ignore the work as they see fit.

City structures cause localized heat zones hotter than nearby rural areas

Urban materials like asphalt and concrete trap heat, while cities lack cooling features like trees and water. Due to hot runoff, urban streams can heat up by as much as 18°F more than forested streams.

After the COVID-19 pandemic, Amsterdam became the first city to apply 'doughnut economics,' a new economic school of thought that defines productivity in terms of environmental impact.

This documentary argues that GM systematically bought up and destroyed streetcar networks across the US in the 1930s, replacing them with buses and helping put the automobile at the center of American culture.

Many issues facing urban environments cannot be solved by smart technologies

Although connecting systems to the Internet of Things can provide improved efficiency in municipal systems, problems such as limited affordable housing are driven by larger socioeconomic factors. Some experts suggest that local governments should focus resources on practical solutions to these issues rather than investing in smart technologies.

The 15-minute city lets residents meet their daily needs within 15 minutes on foot

Many cities have been designed with inefficient layouts that waste time and lower the quality of life of those who live there. In the 15-minute city, essential services—including work, food, education, and health—should all be located within a short walk or bike ride from where people live.
