A New Development Cycle

About a year ago I interviewed my old urbanist friend Jim Kumon on the podcast (Part 1 | Part 2) about his work developing missing middle housing in the Twin Cities and other spots around the country and he mentioned something super interesting that a colleague reminded me of recently about the cycle of our growth regimes in the US that also reverberated around the world.

“And so humanity has a pretty good cycle about every 70 to 80 years where we flip a switch and something serious happens. You know, whether it’s the industrial revolution to things that happened around post-Civil war and the railroads, and then World War II and suburbia, and we’re kind of running on the fumes of that last 80 year cycle, right? We’re kind of past due. And now the pandemic and other things that have changed, we’re into a new cycle. We don’t really know what that is yet.”

These development cycles upended what people knew about cities, transportation, urban planning and design. Urbanization happened intensely and at a full burn since the industrial revolution to where we are now.

What’s more interesting though may be starting to get glimpses of what a new 80 year cycle looks like.

From an energy perspective, the cycles went from wood burning to coal to gasoline and with the Iran War raising the cost of oil, it looks like a lot of countries are looking for stability and certainty in something old but evolved: electricity. A new item in Phenomenal World discusses the rise of the “electrotech” powered by overwhelming Chinese investments in electrification, everything from cars, trains, and ships to energy grids and renewable energy investments exported around the world.

These investments and long term thinking began for China after the 2003 Iraq War and are now being realized on a large scale, and adopted by countries across Asia Pacific, Africa, and Europe.

Here in the United States the highway lobby which includes car manufacturers, oil companies, road builders and more are continuing to pull in the direction of the post world war development regime and against a new electrotech future. But people that live in the existing system are waking up to the expense and unaffordability of oil dependence and the urban systems it has installed and expanded.

Moving aside for the moment the impacts on our planet’s climate, this push towards a monolithic unbalanced transportation system has increased costs for families that I don’t think people still quite grasp. Housing costs tied to job accessibility and distance. Transportation costs tied to how far we are forced to drive, how much new vehicles cost to operate and insure. Public health tied to access to fresh food and care infrastructure.

Electrotech thus isn’t the only answer because much of it is tied to enforcing a previous regime built on automobility. But what comes with electrotech is the potential for a reset button on the poor built environment decisions that have been made over the last 100 years as well as our local economic systems. Instead of profits exported from our neighborhoods, we get to keep them if our utilities and neighborhoods are structured correctly.

A reduction in cost of living for families and improvements in health will grow people’s quality of life and create a value unmatched and unknown in most of the country. It’s something to look forward to, not fight against.

Bonus Episode: Mondays at The Overhead Wire – What it Would Take to Map Every Sidewalk

We’re doing a bit of a crossover episode this week as I wanted to do two things, promote the amazing podcast The Brake hosted by Kea Wilson at Streetsblog USA and Dr. Anat Caspi at The University of Washington and her work focused on creating a platform that inventories Washington State’s sidewalks. This is a reproduction of The Brake’s February 24th episode What It Would Take to Map Every Sidewalk In Your State.

The Washington State sidewalk inventory is now 100% complete but if you’d like to be part of the coalition to get legislative support for continued maintenance make sure to contact the folks working on OS Connect.

Thinking Further on Marchetti’s Constant

April 23, 2026

We’ve been thinking a lot lately about Marchetti’s constant, the idea that people will spend an hour commuting each day, or half an hour each way and adjust lives accordingly based on transportation technologies and housing location choices.

Two research papers posted today feed into that with interesting results. Using data from the Canadian Mobility Survey, researchers at McGill University sought to determine some of the factors that would get people back on transit after the pandemic. What they found was that people that identified as transit riders and had recent transit use were likely future riders with non-users indicating low use intention.

But also included are those (52% of respondents) who believe a 20-35 minute door to door transit trip is reasonable. That time allowance would fit Marchetti’s constant of ~30 minutes commute one way which as Carvalho and El-Geneidy suggest should induce transportation planners to prioritize transit service and projects that get people to jobs within that time window.

The barrier however seems to be car use and people’s sunk in habits which can be psychologically hard to break. Even free transit as seen by researchers in Australia can not seem to break through that car barrier. In some instances though, we know when someone moves to a new house, there’s a possible window for change.

A second research paper in JAPA written in part by our friends Shima Hamidi and Reid Ewing also show another tide pushing against transit usage; the increase in sprawling development. But they found certain levels of compactness increase more active transportation uses while drive times and car ownership went against it. I would then personally posit that building more housing further out blows up any possibility that transit travel times could fit inside of Marchetti’s Constant.

Of course there are new wrinkles in the discussion. Work from home has become more popular for certain professionals post pandemic and commuting is only one type of trip. But Marchetti’s Constant cut in half for other trips ends up in a discussion about 15 minute cities and relates to our previous entries around time poverty and time based planning.

So then what are the solutions that give people a comfortable commute and an affordable home?  We could pave everything over and keep sprawling. That’s the option we continue to choose. Though I still think we’re running out of land for sprawl and from an economic and social standpoint we are hitting a dead end with our singular auto based paradigm.

Or we could be more strategic in thinking about what this actually means from an affordability and quality of life standpoint for residents of our cities. Perhaps Marchetti’s Constant shows us a way forward for cities in a larger context.

Donald Shoup’s Parking Enforcement Army

I love this superhero introduction story to a parking enforcement officer. Grant Nakamura may not be motorists favorite officer, but his valor in the theater of public rights of way as portrayed by Sacramento Bee writer Ariane Lange is now the stuff of legend. A true Shoupista whether he knows it or not.

Of course Officer Nakamura would also be the nemesis of Transportation Secretary Sean Duffy who just released an initiative at USDOT entitled “Freedom to Drive” which as you would expect seems to come from someone who hasn’t been paying attention the last 100 years.

Quote:
“This national effort aims to save American families both time and money by focusing on maximizing roadway capacities, fast-tracking projects that alleviate congestion chokepoints, and leveraging American technology and private-sector partnerships.”

Of course no one has ever thought of this before and it’s not like our state highway departments haven’t been trying to build our way out of congestion. Just one more lane bro.

Smells like a MacGuffin for bike lane removal if you ask me.
