America's Infrastructure Is Stuck in the 1950s. Here's What It Will Take to Build Smart Cities.

The interstate highway system was completed in 1992. The core frameworks for urban traffic management were developed in the mid-20th century. The infrastructure that moves people and goods across America the roads, the signals, the systems was designed for a world that no longer exists.

And it shows.

Jeff DeCoux, Chairman of the Autonomy Institute, put it plainly in his conversation with the Driving Mobility podcast: much of the US infrastructure is stuck in the 1950s. Building 21st century smart cities isn't just about adding technology to old systems. It's about fundamentally rethinking what infrastructure is for and how it works.

Why the Status Quo Is Failing

The infrastructure built for 20th century mobility was designed around a set of assumptions that have been progressively undermined. Vehicles were dumb, human-driven machines. Traffic management was handled by static signals and painted lines. Data about what was happening on roads existed in real time only in the minds of drivers.

That world is gone. Vehicles are becoming computers on wheels. Autonomous systems are moving people and goods without human operators. Connectivity is making real-time data collection and response possible at scales that were unimaginable when the current infrastructure was built.

The problem is that the physical and regulatory infrastructure hasn't kept pace. Roads designed for human drivers create dangerous conditions for mixed-autonomy environments. Signal systems that operate on fixed cycles can't respond dynamically to real-time conditions. Data sharing between vehicles, infrastructure, and operators happens inconsistently, if at all.

The result is an infrastructure layer that actively limits the potential of the technology being deployed on top of it.

What Smart Cities Actually Mean

"Smart city" is a term that gets used loosely, often as shorthand for technology deployment in urban environments. But DeCoux's vision is more specific and more consequential than IoT devices and connected streetlights.

A genuinely smart city is one where infrastructure, vehicles, and systems share data in real time enabling a kind of coordinated intelligence that dramatically improves safety, efficiency, and equity.

That includes:

Vehicle-to-infrastructure communication (V2I). Vehicles that can communicate with traffic signals, road sensors, and management systems receiving real-time information and providing it in return enable a level of coordination that no static infrastructure can achieve. A connected intersection can optimize signal timing in real time based on actual traffic. Emergency vehicles can clear a path before they arrive. Autonomous vehicles can navigate with more precision and safety than any human-only system.

Data-driven infrastructure management. Smart infrastructure generates constant data about road conditions, traffic patterns, and system performance. That data can be used to predict maintenance needs, optimize routing at the network level, and identify and respond to safety issues before they become accidents.

Equity-conscious design. One of the most important and often overlooked dimensions of smart city infrastructure is who it serves. Technology-enabled mobility can either entrench existing inequities in access and mobility or actively address them. The design choices made in smart city development determine which outcome prevails.

The Autonomy Institute's Approach

DeCoux's organization sits at the intersection of technology, policy, and infrastructure which is exactly where smart city development has to happen.

The challenge isn't purely technical. The technology for connected, intelligent infrastructure exists. The challenge is the coordination required to deploy it: across different levels of government, across private companies with competing interests, across legacy systems that weren't built to communicate with each other.

The Autonomy Institute's work focuses on creating the frameworks technical standards, policy models, public-private partnership structures that make coordinated deployment possible.

What It Will Actually Take

Building smart cities at scale requires several things happening in parallel:

Federal investment and standards. Infrastructure is built on long time horizons. Without federal commitment to funding and the establishment of interoperability standards, smart city development will remain fragmented smart in pockets, disconnected at the network level.

Regulatory modernization. Rules written for human-driven vehicles in a pre-data era need to evolve. Autonomous vehicle operation, data sharing, and infrastructure connectivity all require regulatory frameworks that don't yet fully exist.

Public-private partnership. Government can provide the policy framework and public investment. Private technology companies have the innovation capacity. The infrastructure gets built where those two things work together effectively.

Community engagement. Smart city infrastructure changes how people move through their cities. The communities most affected often those with the least political power need to be part of the planning process, not recipients of decisions made without them.

The Urgency

Every year that passes with 1950s infrastructure supporting 21st century mobility is a year of unnecessary accidents, inefficiency, emissions, and economic drag. The technology to do better exists. The question is whether the will to build it does too.

The mobility transformation underway EVs, autonomy, connectivity, new business models creates a once-in-a-generation opportunity to rebuild infrastructure with intention. That window won't stay open indefinitely.
