The goal of the Principles is to promote development patterns that add value to communities. The way to do that, said CNU President John Norquist, is to design streets to play three simultaneous roles: that of a transportation thoroughfare, a commercial marketplace, and a public space. “Typically, U.S. DOT and State DOTs tend to look at roads only in the dimension of movement, and even in that one dimension, their rural-style forms fail in the city,” Norquist says.

The principles are a plain-language counterpart to the Institute of Transportation Engineers’ “Designing Walkable Urban Thoroughfares,” a collaborative effort with CNU which came out in March 2010 and is written in “engineerese” according to Norquist. By contrast, “the Principles are very readable,” he said, “and can be used to encourage local public works authorities or departments of transportation to do something in cities that adds value to neighborhoods.”

Those authorities don’t always have a very good record in that department. For decades now, government transportation policy has been geared toward speeding up long trips, while ignoring issues of walkability and the corresponding value added to neighborhoods. “If one person has to cross the street to get to work, and another drives 25 miles to work in the same building, the government is obsessed with helping the guy who drives, even though the guy who walks contributes more net value [by using fewer resources, spending less time in traffic, etc.]” Norquist told Streetsblog. “If you look at the little blue book, it’s designed to challenge that idea.”

One upshot of that shortsightedness, Norquist explained, is that for too long policymakers have attempted to minimize congestion, often employing the warlike verbs “eliminate,” “destroy” or “combat” to describe their approach to doing so. “But there are worse things than congestion,” says Norquist, who has written before on the subject. “It’s sort of like cholesterol: there’s good and bad. You die without any cholesterol, and cities die if they don’t have congestion. Look at Detroit: they’ve defeated congestion, but now that’s the least of their problems. They’re missing congestion, but federal policy is to destroy it.”

So, why “occupy” TRB? The need for an “occupation,” Norquist said, comes from the continued insistence on the part of transportation policymakers to blindly adhere to the “Green Book,” the roadway design manual published annually by the American Association of State Highway and Transportation Officials. Congestion reduction is paramount in the Green Book, which in Norquist’s view essentially encourages state DOTs to spend their money expanding capacity on freeways.

But Norquist argues that maximizing throughput does not add any value to an urban context, and in fact drains value from the land roads run through. State DOTs should instead be encouraged to concentrate on building dense, walkable street networks.

The first step in shifting that paradigm was CNU’s collaboration with ITE, which resulted in the walkable thoroughfares guide. This “Little Blue Book” represents the next step, a plain-language explanation of a better way to design street networks, accessible enough to reach a much larger audience.

The final step will be its adoption by AASHTO, about which Norquist is cautiously optimistic. “They’ll resist for a while, but they’ll adopt it eventually,” he said.

In this week’s episode of “Moving Beyond the Automobile,” Streetfilms takes you on a guided tour of past, present and future highway removal projects with John Norquist of the Congress for the New Urbanism.

Some of the most well-known highway removals in America — like New York City’s West Side Highway and San Francisco’s Embarcadero Freeway — have actually been unpredictable highway collapses brought on by structural deficiencies or natural disasters. It turns out there are good reasons for not rebuilding these urban highways once they become rubble: They drain the life from the neighborhoods around them, they suck wealth and value out of the city, and they don’t even move traffic that well during rush hour.

Now several cities are pursuing highway removals more intentionally, as a way to reclaim city space for housing, parks, and economic development. CNU has designated ten “Freeways Without Futures” here in North America, and in this video, you’ll hear about the benefits of tearing down the Alaskan Way Viaduct in Seattle, the Sheridan Expressway in the Bronx, the Skyway and Route 5 in Buffalo, and the Claiborne Expressway in New Orleans.

Streetfilms would like to thank The Fund for the Environment & Urban Life for making this series possible.

The Congress for the New Urbanism will meet in Portland, Oregon, in early November for the annual Project for Transportation Reform, a summit to further define emerging policies that embrace entire urban transportation networks, rather than disjointed transportation segments, and that seek to balance modal splits and reduce overall vehicular miles traveled (VMT).

Summit attendees and partners, including Streetsblog, will participate in discussions on emerging network planning and develop a strategy for informing the national transportation infrastructure debate, of particular significance as climate and transportation bills move forward. As the draft CNU Statement of Principles on Transportation Networks [PDF] notes, climate change and infrastructure problems in the U.S. continue to intensify:

The US now has the world's highest level of VMT per capita, while simultaneously experiencing the highest traffic fatality rates of any developed nation. Per capita traffic delay has more than doubled in the United States since 1982. This deterioration in transportation system performance has occurred in spite of an ongoing public investment of more that $200 billion per year in transportation infrastructure."

CNU President John Norquist said the current focus by transportation professionals on road capacity gives us cities like Detroit, where consistent spending to widen roads has destroyed communities.

"Federal and state DOTs don't understand how cities work. They still want to take rural forms and jam big roads into cities." he said. "Rather than measuring projected traffic flow, they should be measuring how much value it adds to a neighborhood. The U.S. can't afford to be energy-wasting and spending money on projects that destroy the value of neighborhoods."

U.S. Representative Earl Blumenauer will kick off the summit and representatives from Oregon Metro will showcase the many innovative transportation and design policies they have implemented in the region that have given Portland one of the highest walking, transit, and bicycle mode shares in the country.

Summit organizers hope to develop the language around network-wide transportation reform so the CNU can persuade lawmakers in Washington, D.C. to incorporate this new urban vision into upcoming climate and transportation legislation.

Marcy McInelly, co-chair of the CNU's transportation reform initiatives and principle of Sera Architects, said, "Reform is about giving more latitude to use highway funds for pieces of the network that may not be for highways. Right now the federal funds have to increase vehicular mobility, which raises VMT. If you had a funding formula that allowed you to count benefits to cost, it would almost always [result in] the other modes besides cars coming out [as] more beneficial. It would balance consideration of other modes."

Norquist said the CNU is working with the Institute for Transportation Engineers (ITE), the most significant body of professional transportation engineers in the country, to develop transportation standards that raise the profile of urban streets to match that of rural roads and freeways in guides like AASHTO's Green Book for highway and street design.

According to Norquist, reform initiatives should focus on altering "the functional classification system. The current regulatory framework tries to feed future traffic demand, instead of trying to facilitate the network."

Referring to the traditional advocacy position that tries to chip away at the 80-20 funding formula (80 percent of federal funding for freeways, 20 percent for transit), Norquist said a more fundamental change is needed.

"We're completely for the idea of changing the 80-20 split. But even if the environmental community wins and gets 25-75, you're still spending 75 percent of the money on road capacity. They should focus on creating roads that are useful and pleasant and create a place where people actually want to be."

Norquist also promised the conference would be fun. "This conference will have the most dynamic and exciting traffic engineers in the world," he said, with a laugh. "These are the reform traffic engineers, the recovering traffic engineers."

The Project for Transportation Reform with take place from November 4-6 and registration is still open. Streetsblog will be covering the summit with regular stories and tweets, so stay tuned.

In the second part of our interview (read the first part here), Norquist discusses these victories and setbacks, and how federal policy can help cities and towns do the right thing.

Ben Fried: Expanding the transit system in Milwaukee has been a very long, protracted process. You wanted to build light rail. What sort of resistance did you meet from other public officials?

Cincinnati, Milwaukee, Buffalo, Detroit, Cleveland -- the regional planning commissions they have really aren’t looking out for city interests, they're looking out for the exurban interests.

It’s frustrating, because Milwaukee was always ranked by the Federal Transit Administration as one of the best places to put in a light rail, because it was built around the street car system. There was over 350 miles of street car in Milwaukee at the end of the war, 200 miles of inner urban. We had a really, really good transit system and by 1958 it was all gone. But the land use patterns were all built around street car lines. Now I think my successor, Tom Barrett, has got himself some clout with this. They put an earmark in the budget bill that just passed that gave him control of a nice big chunk of money, so he might be able to get that street car going.

BF: So the dispute between you and the county executives, is that emblematic, would you say, of the basic problem with MPOs?

JN: It depends on who runs the MPO. New York and Chicago have their MPOs under control. We have enough clout in Chicago that the local regional planning commission -- CMAP -- they're not going to turn around and screw Chicago. Chicago has a lot of representation on CMAP’s board. In New York, basically New York runs its own regional system -- sometimes the metro system has too much interference from the state, but basically New York City can call its own shot when it comes to planning. And that’s not true in a lot of cities. Cincinnati, Milwaukee, Buffalo, Detroit, Cleveland, the regional planning commissions they have really aren’t looking out for city interests, they're looking out for the exurban interests.

BF: We’ve got a potential freeway teardown project here in New York, the Sheridan Expressway, it was number two on CNU’s list of the top teardown candidates. Could you walk us through what you had to go through with your freeway teardown in Milwaukee -- who did you have to win over to achieve that?

JN: The Sheridan is ready to go. It has a nice low traffic count, so it’s hard to argue that it’s really necessary. But what did I go through? Well, the first thing was, it’s so counterintuitive to do these things that the first reaction was from very reasonable people -- ordinary citizens, the traffic engineers, neighborhood people, even very progressive people -- “You want to do what? You want to tear that -- what?” You know, it doesn’t compute, it sounds like a wacky thing to do. You have to have patience and spend a lot of time in meetings letting people beat the living hell out of you. And then you get to a certain point where people say, “Hey, wait, I think I understand what you mean. You’re saying the freeway’s a blighting influence.” And you just go through all the arguments against it, but the biggest argument for it is it just makes the place function a lot better and add more value and be a place where people actually want to be.

In the mid and late 70s a whole bunch of legislators were elected who were against freeways, people who organized and went door to door. If we hadn’t won those battles Milwaukee would have been devastated.

So you go through all these value calculation fights, and then finally you need to play your political cards. In Milwaukee the anti-freeway movement began in early 70s, and in the mid and late 70s a whole bunch of legislators were elected who were against freeways, people who organized and went door to door, they won the battles. If we hadn’t won those battles Milwaukee would have been devastated, but we’ve killed about half the freeways they had planned on building. And that saved the city really from being in a very similar situation to what Detroit is in right now.

BF: Are some of the freeway projects the Wisconsin DOT is planning now, are those in metro Milwaukee?

JN: We have several on there, they're all unnecessary, they're all dead weight loss. It’s really disgusting and it shows you how hard it is to get them to look at it in a different way. The I-94 widening -- it’s already six lanes, they want to make it eight lanes from Milwaukee down to the Illinois border. And they want to do a new interchange, called the “Zoo Interchange,” which will cost close to $1 billion. A lot of these stimulus projects are completely unnecessary and they don’t make sense. To route your grade-separated traffic through the most expensive real estate in the state of Wisconsin? It’s insane. They don't do it in Europe. They have freeways, but they're between cities, not in cities. They go around the outer edge with belt lines, but they don’t jam up through the most built-up places, because it just concentrates traffic and creates more congestion at the nodes.

A lot of these stimulus projects are completely unnecessary and they don’t make sense. To route your grade-separated traffic through the most expensive real estate in the state of Wisconsin? It’s insane.

Look at it not just from a big city standpoint, look at it from a medium- or small-sized city standpoint. Let’s say you were in New York wine country and you come to Ithaca. In the old days, instead of a bypass they’d have a truck route around the outer edge of the street grid. You might go a little bit faster, 35 miles an hour instead of 25, but it’s a little longer distance, so it’s pretty much an equal choice whether you drive through the middle of town or you go on the outer edge. And if you're driving a truck and you're going on through-traffic you take the truck route.

Well, now they don’t even have that option anymore, all they have is a Mercedes-Benz test track, a highly-banked, grade-separated freeway that routes all the traffic around the city and then you get the inevitable death of any retail in the middle. You end up with antique shops and empty buildings. And then you get the big boxes out on the beltway.

These small towns, they don’t need beltways. Give them another option and they might choose it. If they still want to build a beltway and they want to help pay for it, fine, but the feds should give them the kind of options that allow urban real estate development, job development, walkability, connectivity, all these things. Higher economic performance, higher environmental performance. Those are all possible when you create a wide variety of choices, instead of just going right to grade separation. That’s basically saying, "We only fund through-traffic -- if you want to go a long distance, we’re into funding it."

The feds don’t look at it in terms of the economics. Traditionally, there’s three purposes for a road: movement, economic and social interaction. Those are the three things that traditionally a thoroughfare in an urban area did for thousands of years. That’s what it was. And then in the last 60 years it’s all dumbed down to just one thing -- vehicle movement -- and the other stuff doesn’t matter. Well that’s really stupid. The federal government collects a lot of taxes from hardworking people in the United States, and they shouldn’t just think that the only purpose of investment in transportation is through-traffic.
