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.

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.

Smart cities like Songdo, South Korea, have created isolating environments

Built as a futuristic, eco-friendly city filled with smart features like pneumatic trash systems and app-controlled homes, the town provides limited opportunities for face-to-face interactions amid sterile backdrops. A focus on high-rise housing amplifies the lonely, disconnected atmosphere.

Smart cities support interdepartmental goals by facilitating shared infrastructure

Instead of working in isolation, municipal departments can share data, such as lighting and telecom needs, seamlessly and collaborate to solve larger-scale problems together. Integrating public feedback systems can further improve city services and sustainability.

Toronto's downtown has 18 miles of underground pedestrian tunnels

Known as the "Path," these tunnels have helped reduce pedestrian traffic on Toronto's busy downtown streets for over a century. They were first built by local business owners, prompting a network effect of add-on tunnels.

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.

LA used to have one of the best mass transit systems in the country

A century ago, Los Angeles had one of the greatest urban transit networks in America. Today, driving in LA traffic can still be faster than taking the train. The city's rail design, which funnels traffic through a single point, fails to support a city with such a spread-out population.

Building new supermarkets in food deserts likely won't help as much as nutrition education in closing healthy-eating gaps.

Areas of densely packed native trees and drought-tolerant plants within cities can pull carbon dioxide from the air, cool surrounding neighborhoods, and support local wildlife. The idea behind microforests traces back over 50 years to Japanese ecologist Dr. Akira Miyawaki, who promoted planting whole ecosystems to restore degraded land.

Critics of concierge medicine argue it's worsening physician shortages and expanding inequity

Some research suggests that the average wait time for a primary care visit in major US cities can be 21 days. Subscription-based medical practices offer faster in-person and virtual appointment options, but the price barrier to this type of service may worsen inequity in healthcare access.

Since then, modified versions of Dijkstra's formulation comprise the processing backbone of systems such as Google Maps and Apple Maps.

How parking infrastructure reveals a region's values

As cars became more popular, the need for city parking increased. In Europe, well-established cities with limited space generally opted for more expensive underground parking beneath public spaces to preserve aesthetics. Available land and decentralized planning in the US saw more parking lots and garages built. These decisions reveal broader policy realities for these regions.
