Transportation That Delivers Results

Communities across the country have asked for safer streets, cleaner air, transportation they can afford, and reliable access to the jobs, schools, and medical care they depend on.

Somehow, we're getting none of it.

“The IIJA was not a good authorization at all… It didn't make our roads safer… It accomplished zero of its goals.”

Beth Osborne, Smart Growth America

Why can't we manage to deliver what we want?

Some blame politics, funding, or American culture. But what if the root of the problem is a missing introduction? Three conversations already have the tools we need. They just haven't met.

What if the solution is hiding in plain sight?

Common Ground leads to results Abundance, Advocacy and Civic Tech each point an arrow at Results. Abundance contributes reach, Civic Tech contributes mechanism, and Advocacy contributes ground truth. RESULTS ABUNDANCE REACH ADVOCACY GROUND TRUTH CIVIC TECH MECHANISM

The Argument

Break the Cycle. Deliver Results.

Every community wants some version of the same four things from transportation: safety, affordability, sustainability, accessibility.

And still: despite hundreds of billions in annual transportation spending, the U.S. has the most dangerous roads in the developed world, roughly half the population live in transportation cost-burdened households, recent investment is increasing emissions like 50 new coal-fired power plants, and per Beth Osborne (Smart Growth America), the current approach “puts people farther away from the places they need to go, stymying access to opportunity.”

Why can’t transportation deliver any of the results we all want? Three conversations are circling this problem — and each is missing a crucial piece of the puzzle.

Abundance

Abundance has the reach: it built a broad bipartisan coalition around housing. But its approach to transportation fails to honor its own core argument: government must deliver results, not rhetoric, to win back the trust of the American public. For now, Abundance's approach to transportation is focused on lowering costs and speeding delivery of projects, which is not the same as delivering results (see Infrastructure Delivery is not Outcomes Delivery).

Civic Tech & State Capacity

Civic technology and state capacity has the mechanism: the Recoding America Fund exists to build a new operating model for government (not just digital government) that can deliver policy outcomes: building the field, filling in the gaps wherever government fails to turn intent into results. Transportation is one of those gaps, but hasn't yet received the attention of CivTech.

Transportation Advocacy

Transportation advocacy has the ground truth: local trust and representation in nearly every city and county. What it lacks is a way to hold an agency to a goal once it's adopted, or a stage big enough to make the case nationally.

Each can provide the necessary piece the others are missing. That's the theory this site tests.

The Roadmap

What Comes Next

The argument ends with an ask to each of the three movements. A thought leader in Abundance could champion the transportation outcomes-delivery case the same way cost/delivery reform got carried into the mainstream. A thought leader in civic tech could suggest an honest audit of transportation's current wins — which are real reform, and which just relieve pressure — and start building the mechanism to deliver results. And transportation advocacy, which has the most at stake of the three, could be the one to insist that abundance's reach and civic tech's mechanism finally get pointed here.

Three conversations with everything to gain by joining forces, and nothing to lose.

Mission

Three conversations are already working to help government deliver results — abundance, civic technology, and transportation advocacy — and each has exactly what the other two need. Transportation Abundance exists to make the introduction: helping each movement recognize its missing tools, see how these tools succeed with the others, and start using them.

Vision

A transportation system where our investments and policies are moving us closer to the things society wants — not further away.

What is “abundance”?

Abundance is the idea — most associated with Derek Thompson and Ezra Klein's 2025 book of the same name — that many of America's most pressing shortages (housing, clean energy, infrastructure) aren't the result of insufficient ambition or funding, but of self-imposed institutional barriers: permitting processes, procurement rules, and review requirements that make it slow and expensive to build things governments and markets already agree we need. The abundance argument is that removing those barriers, not just spending more money, is the fastest path to more housing, more clean energy, and better infrastructure.

A second part of the abundance argument gets less attention, but is perhaps more important: government must rebuild public trust by delivering visible results, not just performing the values its base wants to hear or winning the argument. Building more but failing to deliver results keeps the promise only half kept.

How does transportation fit into abundance?

Transportation has its own version of housing's artificial scarcity: permitting and procurement rules that make American transit and road projects cost multiples of what peer countries pay, and take years longer to deliver. That cost/delivery conversation is already underway, led by research like the NYU Transit Costs Project and the Institute for Progress Transit Abundance Playbook. Transportationabundance.org starts there — but argues the movement needs a second, currently missing piece: accountability not just for building things, but for whether building them actually improves how people get around.

What does TransportationAbundance.org actually do?

Right now, this site is where I'm building and publishing that argument in public — synthesizing research from Brookings, Niskanen, and academic transportation economists into a case for outcomes accountability, and testing it with the researchers, funders, and practitioners closest to the problem.

It's also the foundation for what I hope becomes a more formal role: a fellowship, research platform, or organization built around closing the gap between transportation goals and transportation results. If that's a fit for your work — as a funder, a collaborator, or an institutional home — I'd like to hear from you.

Who are the key voices in the abundance movement?

Klein and Thompson gave the movement its name and its clearest public argument. Alongside them, a state-capacity wing — Jennifer Pahlka (Recoding America), the Niskanen Center, and the Recoding America Fund — has focused specifically on why government institutions struggle to execute, drawing on lessons from digital government and benefits delivery. A YIMBY-adjacent wing has applied abundance thinking most extensively to housing. Transportation abundance sits at the intersection of these conversations.

How does Transportation Abundance relate to YIMBY?

On housing, YIMBYs built four distinct tools for holding government accountable to outcomes: analytical rigor (quantifying exactly how many units a reform unlocks), public testimony (showing up at hearings to demand government keep its own commitments), organizational breadth (chapters in nearly every city), and legal action (suing when government fails to deliver). None of those tools has been systematically pointed at transportation — even though housing growth needs transportation to scale in parallel. Transportation abundance is the case for building that same accountability posture: not asking YIMBYs to become transportation advocates, but asking transportation to adopt YIMBY-style rigor about outcomes, not just cost and delivery. There's a Sonja Trauss-shaped hole in transportation advocacy.

How is this different from just wanting more transit funding?

Manville, Taylor, and Blumenberg's research on U.S. transit documents something specific to transit funding: since 2000, transit investment has grown faster than service hours, which have grown faster than ridership; put simply, agencies have spent more, run more service, and still lost riders per capita. Los Angeles is the sharpest case: the county spent billions since 1985 building over 100 miles of new rail, while per-capita ridership fell roughly 25% between 1985 and 2015 — even as the population grew by nearly two million people over the same period.

The pattern holds across individual cities too, not just in aggregate. Baltimore increased bus service 8% between 2015 and 2018 — and lost 13% of its ridership anyway. More service, run well, doesn't guarantee more riders if the underlying product isn't built around what riders actually need.

Their diagnosis, documented in Infrastructure Delivery Is Not Outcomes Delivery, is that the voters and officials who fund transit often aren't the people who ride it, and the two groups don't always want the same things — so investment gets built to win political support, not to serve the traveling public. More money doesn't fix that; it just builds more of a product that wasn't designed around what riders actually need.

Counterargument

The best objections, answered.

Isn't this just the abundance movement's blind spot showing? David Zipper has argued that improving project cost and delivery will just produce more roadway projects.

Yes, if the abundance movement's transportation wing stops at “build faster and cheaper,” it hasn't actually delivered on abundance's core promise — government needs to deliver results, not rhetoric. The response isn't to abandon the cost/delivery work Zipper is critiquing, nor is it to abandon Abundance as a viable path to better outcomes; it's to join forces as discussed in Break the Cycle. Deliver Results.

Improved land use — more density, more transit-oriented development — is the best path to better transportation results.

Density genuinely matters — Zipper is right that living closer to destinations shortens trips and lowers the cost of getting around. But his and Alex Armlovich's related post about transit-oriented development exposes the gap in the density-first argument: TOD only delivers on its promise if the transit it's built near is actually part of a functioning, interconnected, reliable network — and most often, it isn't. From a land-use perspective, density is unambiguously good policy. From a transportation-outcomes perspective, density is an input — arguably the most important input, but still an input, not the outcome itself.

Building density near a transit line doesn't guarantee anyone can live car-free or car-light unless the transit, walking, and biking networks can effectively substitute for driving. That's the same accountability gap this whole argument is about, just one layer closer to land use: a jurisdiction can build all the density it wants and still never measure, or be held to, whether the surrounding system actually lets people leave the car at home.

AVs will deliver these outcomes.

Possibly, for one outcome — AVs may plausibly reduce crash rates by removing human error, though the evidence is still developing and often overstated. But safety is one higher-order outcome among several, not a substitute for the others. AVs don't scale well in dense urban environments and therefore aren't a solution to mobility in the places where human-operated vehicles are currently failing to scale. And AVs are, almost by design, an expensive way to move one person — nothing about the technology addresses affordability. Treating AVs as a general answer to “outcomes” mistakes a possible safety improvement for the whole higher-order-outcomes framework.

States already track ridership, VMT, and mode share. Isn't that outcomes accountability?

Tracking a proxy isn't the same as tracking an outcome. Ridership, vehicle miles traveled, and mode share are measurements that may or may not indicate progress toward what actually matters — accessibility, safety, sustainability, affordability. Rising ridership or falling VMT doesn't prove people can reach more of the destinations they need. Most states that report these numbers have never closed the loop back to the higher-order outcome the proxy was supposed to indicate. That gap — reporting a proxy without ever testing what it means for the real goal — is a large part of what this argument is trying to fix.

Aren't transportation agencies already trying to drive results — they're just underfunded and understaffed?

Often, yes — but underfunding and the absence of institutional mechanisms to drive results are two different problems, and more money alone doesn't solve the second one. An agency can be fully staffed and well-funded and still have no structure that connects a stated goal to an investment decision to a measured result. The argument here isn't that agencies or the people in them have failed, it's that the system is broken, and fixing it is separate work from building a budget.

High-speed rail is what's actually needed.

Shill and Levine address this directly in Transportation for the Abundant Society: abundance's transportation discourse has focused disproportionately on high-speed rail and megaprojects, but HSR is largely irrelevant to the everyday task of moving within a metro area — which is where the vast majority of trips, and the vast majority of the accessibility problem, actually happen. Even its best-case benefits are concentrated in a handful of corridors. The fixation on HSR as abundance's transportation answer has crowded out attention to the areas of focus highlighted by Shill and Levine and on this site — which are more consequential and widely applicable.

Redistributed wealth is how you actually deliver outcomes.

Klein and Thompson address this directly: “the world we want requires more than redistribution.” Redistribution is a claim about who gets a fixed amount of something. It doesn't ask whether the system producing that something actually works. Redistributing transportation dollars more equitably — toward underserved communities, away from wealthy ones — doesn't fix the accountability gap this whole site is about. A system with no mechanism to guarantee spending produces safety, or access, or a livable climate, fails everyone using it, regardless of who the money is routed to first. Fixing who gets the money is a different problem from fixing what the money actually buys. This site is about the second problem. Redistribution, however important on its own terms, doesn't solve it.

This is too big. Let's do something more manageable, like e-bikes and micromobility.

Micromobility is genuinely good policy, and nothing here argues against it. But a coalition that lets itself get pulled into every adjacent, easier-to-win cause dilutes the one lever that actually moves the outcome. Micromobility investment is valuable on its own terms; it is not a substitute for building the institutional mechanism that connects any transportation goal — including micromobility's own stated goals — to measured results. Somebody has to do the harder, structural work. That doesn't mean nobody should do the easier, adjacent work too.

Isn’t this a moonshot, like the Green New Deal or Medicare for All?

In ambition, yes. Safer streets, affordable travel, cleaner air, and real access to jobs and medical care are as big as any goal in American politics. But the approach differs in two ways.

First, transportation has no equivalent of the Green New Deal or Medicare for All. Those proposals are how progressives show where they stand: backing them is a public commitment that voters and allies can check. Transportation has no such marker, so a progressive label says little about how someone will act on it. Beth Osborne (Smart Growth America) documents the result. In Congress, “Democrats don’t take their progressive stances into transportation”: the two Obama-era authorizations kept the same 80% highway, 20% transit structure in place since 1991. In the states, Washington’s “climate governor” still favored new highways, while North Dakota, South Dakota, Nebraska, Wyoming, and Montana cut emissions more than California, Washington, and Connecticut. Without a clear commitment to measure leaders against, transportation goals stay rhetoric.

Second, it doesn’t start with a bigger budget. The U.S. already spends hundreds of billions a year on transportation, and gets poor returns for it. Pointing that money at results through better project selection and real accountability could deliver far more while spending less. Same scale of ambition, a fraction of the new cost.

That’s what this site is for: making the case for transportation’s missing commitment. It isn’t a new program. It’s a standard of results that leaders can be held to.

Housing has a clean metric: units built. Transportation doesn't have an equivalent. Isn't that why outcomes accountability is harder here?

It's genuinely harder, but not for the reason usually assumed. The difficulty isn't that transportation lacks measurable outcomes — Brookings' 50-state survey shows states already collecting meaningful data in pockets, on safety, on emissions, on access. The difficulty is that transportation has multiple, sometimes competing higher-order outcomes rather than one legible number, which makes institutional follow-through harder to design. That's a reason to build a more careful mechanism — one that can hold a jurisdiction accountable to whichever outcomes it commits to — not a reason to give up on mechanism-building altogether.

The current presidential administration is hostile to anything non-car.

True, but the vast majority of transportation decision-making — project selection, service design, community organizing — happens at the state and local level, largely insulated from federal executive posture. And even those who support car-centric transportation policy should recognize its failure to deliver on its own stated higher-order outcomes. Federal support for car-central travel doesn't produce safer roads, lower costs, or better access either. The gap between intentions and results isn't partisan — it shows up in red states and blue states alike, in car-first policy and multimodal policy alike.

We just need to win elections and get the right people in charge.

Jen Pahlka's central frustration, developed across her writing and interviews since Recoding America, is precisely that American political culture over-focuses on policy and politics and under-focuses on implementation — winning the argument, winning the office, passing the bill — while treating what happens after as a technical afterthought rather than the actual site of success or failure. Her point isn't that politics doesn't matter. It's that a movement that stops at “get the right people elected” hasn't finished the job; it's just gotten to the starting line. The right officials, without institutional mechanisms that outlast any single administration, produce the same undelivered promises the next election cycle.

Americans don't actually want these outcomes.

This is precisely the kind of cynicism the abundance movement exists to push back against. Assuming insincerity when a democratically adopted goal goes unmet is a lazy way to avoid fixing what's actually standing in the way.

Fine, Americans want these outcomes, but they clearly don't want to change their behavior.

This assumes the choice being tested is real, and it usually isn't. Travelers, like any customers, choose among products based on a product's competitive advantages relative to its alternatives. Right now, government transportation policy — road design, parking mandates, signal timing, funding — overwhelmingly prioritizes the car product, often in direct contradiction to adopted goals about sustainability and multimodalism. That's not a revealed preference experiment; it's a rigged one. Before concluding that Americans have chosen cars and don't want alternatives, the honest test is to see what happens when other products are actually allowed to compete on their own merits — safety, cost, reliability, time — rather than judging the results of an uneven competition.
