Traffic Blues

Traffic in Miami.

Around this time of year, many of us are feeling overwhelmed by congestion.

Tis the season for traffic.

Fa la la la …blah.

Yes, I am talking about annoying, frustrating traffic punctuated by bad drivers and pedestrians who are oblivious to DO NOT WALK signs that are there to stop you from being maimed by the—bad and good drivers.

Bah humbug.

Now I wish I had good news for you regarding this vexing topic.

I don’t. There are no quick fixes and solutions will require us to think differently; never an easy thing.

But I do have a few things for you to consider.

First, you are not sitting in traffic, you are traffic. We all contribute.

Second, traffic never gets better.

That may sound defeatist, but if you believe David Edmondson, a transportation planner and a consultant with the Edmondson Planning and Design firm in Washington D.C. building more lanes and more roads won’t solve the problem, in fact, it makes congestion worse.

The culprit is something called induced demand.

Here’s what Edmondson recently wrote in a cheery little article called “Why Traffic Never Gets Better.”

“In 1962, (economist) Anthony Downs wrote that there is a Fundamental Law of Highway Congestion: no matter how much road is built, the highway will end up congested again. In decades since then, the United States has undergone a massive experiment in expanding most major roads, leading to an additional conclusion: there is a Fundamental Law of Traffic Congestion impacting both highways and major roads. In both cases, congestion will return to previous levels about 5 years after a widening. This is the phenomenon known as induced demand.”

Researchers looking at this issue use a measure called “lane-miles” to get at how much road is being built. A lane mile is the length of the road multiplied by how many lanes it has—a mile of two-lane road is two lane-miles, for instance. Add another two lanes to that stretch and you’ve built another two lane-miles.

 

Studies differ on exactly how much new driving is induced when new lane-miles are built. But they all hover at around a 1-to-1 ratio: a 1% increase in lane-miles results in a 1% increase in driving. But some studies show a worse ratio. The more lane miles, the worse that traffic gets.

Double ugh.

So sorry asphalt contractors, we can’t pave our way out of this conundrum.

Here’s Edmondson again.

“Why this occurs is relatively straightforward. Traffic demand is based on the immediate cost of driving: gas plus travel time. Reduce the time it takes to drive somewhere, and that trip becomes cheaper. People drive more because it now costs less. But as more people choose to drive more miles, the cost of driving settles back to where it was originally. Congestion is where the road system hits equilibrium, its happy place. Congestion always wins.”

Double ugh.

“Congestion always wins” is a terrible slogan. I do not recommend that future candidates use it.

But yet we keep adding lanes despite 62 years of research that says it doesn’t work.

Why?
Because some people believe widening does relieve congestion and others believe that if you add bike lanes and transit improvements alongside the widened roads, congestion will improve.

This indicates that politicians and engineers are still debating science, or they don’t trust the studies.

One researcher who has studied the issue said this in a New York Times story in 2023.

“If you keep adding lanes because you want to reduce traffic congestion, you have to be really determined not to learn from history.”

Makes sense.

But does that mean there are no answers?

Before we trot out the usual solutions: mixed use development that enables people to avoid trips, investments in mass transit, congestion tolling etc., let’s acknowledge that not everyone considers congestion a problem. Some urban thinkers consider congestion a good thing.

Blasphemy!

Ok, wait a second, let’s unpack what these heretics are saying before we condemn them.

Charles Marohn is the influential founder of the Strong Towns movement. We once hosted him in Delray Beach where he gave an interesting talk on his views before a packed crowd at Northern Trust on Atlantic Avenue.

He never calls congestion a problem.

“It is clearly not,” writes Marohn.  “Within our places — on our streets — congestion is an indicator of success. As Yogi Berra reportedly said: “Nobody goes there anymore because it is too busy.” Indeed. The most successful places are full of congestion. On the roads we build to travel between places, congestion signals many things but, for me anyway, it primarily indicates America’s cultural — and the engineering profession’s technical — misunderstanding of the systems we have built.”

Ok, Chuck Marohn, you have our attention.

Mr. Marohn believes we have created a system of roads destined to fail us. His answer: “the only way to deal with it and still have a successful economy is to address it at the source. We need to absorb those trips locally before they become a flood. Instead of building lanes, we need to build corner stores. We need local economic ecosystems that create jobs, opportunities and destinations for people as an alternative to those they can only get to by driving.

For nearly seven decades, our national transportation obsession has been about maximizing the amount that you can drive. Today, we need to focus on minimizing the amount you are forced to drive. If we develop a system that responds to congestion by creating local options, we will not only waste less money on transportation projects that accomplish little, but we will be strengthening the finances of our cities. We can spend way less and get way more in return. That’s the essence of a Strong Towns approach.”

In other words, Marohn’s solution is to turn soulless roads into streets, so instead of building speedways we build places that include a mix of uses.

In other words, do what Delray did to U.S. 1.

Here’s more Strong Towns thinking from Mr. Marohn.

“When I suggest that we convert our STROADS back into streets — changing unproductive transportation corridors into platforms for growth and investment — the pushback I get is that congestion will become unbearable. If we narrow those lanes, bring back the on-street parking, take out the turn lanes, remove the traffic signals, slow the automobile speeds and welcome a more complex urban environment, somehow we wouldn’t all be able to rapidly get to where we want to go.

To this I say: AMEN!

We have spent untold amounts of wealth reducing the time spent in the first and last mile of each auto trip. The result: a nation of fragile and unproductive places, an economy subsisting on financial meth and other desperation moves along with a built environment that forces (let me emphasize that to reinforce the notion that having only one option in a marketplace is quite un-American) FORCES nearly all of us to drive everywhere we need to go.

If we began to unwind this system, converting those nasty STROAD corridors into wealth producing streets, we would have congestion, of course, but in this case, congestion would simply be another word for opportunity. And not the type of opportunity that benefits the global corporation that can purchase toilet paper for 0.005 cents over cost, ship it around the world on subsidized transportation systems using subsidized energy all while protected by the U.S. military. I’m talking about opportunity for real people in real neighborhoods.

Need a gallon of milk? In an America of Strong Towns, you can get in your car and drive or — if the cost in terms of your time or quality of experience is worth more to you than you would choose to give up in dollar wealth — you can walk down the street to the corner grocer. Today that is considered quaint, but stop wasting enormous sums of money fighting congestion and now that becomes a real choice. Am I going to sit in my car for half an hour on clogged streets to save two dimes on milk or will I just walk up the block?”

Intriguing.

Of course, none of this happens overnight. Or without significant political will that pushes back against NIMBYism and old ideas.

P.S. Some of this thinking can be employed to battle the lack of housing.

Want to keep your big box?

How about letting people live next door to the box? Or how about converting all those one-story post offices to mixed use by allowing people to live above that use?

Regardless, we need to change our approach to congestion and begin to embrace some new ideas.

Meanwhile, be careful out there. And please don’t walk on red.

Have a wonderful New Year and thanks for reading.

The G Word

There’s a new book out about the gentrification of Brooklyn and how it went from crime riddled to cool.
As the book “The New Brooklyn: What it Takes to Bring a City Back” notes, ask any mayor–well not any mayor– what they want and they’ll say safe and bustling streets,  events, culture, busy stores and restaurants, jobs and visitors.
In other words, gentrification. Only we don’t say the word.

Because it’s loaded.
Because gentrification often comes with displacement. When values go up, poor and middle class residents often get priced out. And when rents go up, it can mean the loss of treasured retailers and restaurants.
Gentrification yields winners and losers. There’s no doubt. But the book on Brooklyn notes that when cities decline everyone loses. So why not just leave everything alone then?

Well, it’s just not that simple in most cases. Change is a constant–unless you live in an historic district. Most of us don’t.

I was thinking about this when we ventured to Olio restaurant on a recent beautiful Saturday night.
We hadn’t been to Olio in a while.

It’s located south of Atlantic in what some are calling the “Sofa” district for south of the avenue.
Downtown was mobbed, lots of people walking, dining and riding the Downtowner.
We ran into two friends from Pittsburgh who visit for a month every year and they were astounded and delighted by the action and the new businesses.
They loved it.
Sitting outside at Olio and enjoying a wonderful evening, I thought to myself if I didn’t already live here this is where I’d want to be.
A small town with big city amenities–great restaurants, interesting shops, great hotels, culture and a beautiful beach.
At least that’s how I see downtown Delray Beach.
But we had to park a block and a half away and when we left the restaurant and went home there was a back-up at the intersection of Swinton and Atlantic. For us, we didn’t mind at all. It’s ok to walk a block or so to park. If we wanted too, we could have taken an Uber or a Lyft or the aforementioned Downtowner, which fortunately serves my neighborhood.

As for the back up at Swinton and Atlantic— eventually it moves and it doesn’t happen all year–only during “season” or during weekends when stores and restaurants are doing brisk sales. I can live with the slight inconvenience (emphasis on slight) because I want to see downtown businesses thrive.

But others don’t see it quite the same way. They consider parking a hassle or worse and traffic and congestion as a terrible inconvenience.
They see some favorite businesses close or move and it bothers them. I get it. I miss a few of those places too. (To paraphrase Simon & Garfunkel: “where have you gone Green Owl, a breakfast crowd turns its lonely eyes to you”).
But…
Things change.
Cities change.
Downtowns evolve.
Sometimes they boom.
Sometimes they bust.
When they boom there are winners.
And there are losers.
But when cities bust, there are only losers.
I’ve lived here 30 years.
Our downtown has changed during that time.
There wasn’t much south of the avenue in the 80s and 90s–a sausage factory, empty lots and blight. Today, there’s Sofa, the apartment complex, an indoor cycling facility, Olio and more.
I like it. Based on the crowds we’re seeing and the property values of nearby neighborhoods I’m guessing others do too.
When I moved into town, Pineapple Grove was anchored by a tire store, empty streets and a self service car wash. Today, there’s Brule, Papas Tapas, the Coffee District, Christina’s, a bookstore, gym, other great restaurants, the Arts Garage, Bedner’s and Artists Alley.
I like it. It’s better than it was. A lot better, in my opinion.
There wasn’t much happening on 4th Avenue north of the avenue. Today, Beer Trade Company is killing it and Ocean City Lofts is a coveted address.
West Atlantic Avenue has been vastly improved since the 80s.
It still has a long way to go but it’s been beautified with paver bricks, the Elizabeth Wesley Plaza, a gateway feature and improved by investments such as the Fairfield Inn and Atlantic Grove which has some great spots including Ziree and Windy City Pizza.
It’s a lot better and vastly safer than it was when hundreds of people would be hanging out near the old Paradise Club on Sunday nights. Police officers and firefighters were routinely showered with rocks when they responded to calls for help.
Change is not always easy and it always comes with trade offs–create a place that is attractive and you get traffic.
Raise rents because your successful and beloved stores may leave. But because your successful you won’t see vacancies.
You get the picture.
Gentrification has winners and losers, decline has nothing but losers.
The key is to be aware and to be sensitive to those impacted and find creative ways so they can win too.  Create housing, job and cultural opportunities for all, get involved in your schools, encourage the private sector to offer creative space and not chase away artists, develop other parts of your city. But don’t stop paying attention to your core.

Be hyper vigilant about what’s happening and do what you can to create opportunities for all–small businesses, young families, kids returning after school, retirees, start-ups and growing companies.

Manage but don’t stifle.

Encourage ideas.

Reach out to your citizens  and don’t keep your own counsel.

Lead with humility, praise others, model civility, inclusiveness, exhibit gratitude and foster civic pride.

Repeat. Because you are never done. And that’s what’s so fascinating about cities.

FAU Scientists to Study Traffic

FAULOGO

FAU has received a $300,000 grant from the Florida Department of Transportation and a $100,000 grant from the City of Miami Beach to research and test more efficient traffic signals.

Traffic jams not only make daily commutes exasperating, they also contribute to excessive fuel consumption and air pollution. According to the U.S. Department of Transportation, outdated traffic signaling accounts for more than 10 percent of all traffic delays. Adaptive traffic control systems or “smart” traffic lights allow intersection signals to adjust to real-time traffic conditions like accidents, road construction and even weather. In the U.S., adaptive signal control technologies have been in use for approximately 20 years, but have been deployed on less than 3 percent of existing traffic signals. Florida, California and Michigan are among the states paving the way to make traffic signal improvements a priority.

Researchers in the Laboratory for Adaptive Traffic Operations & Management (LATOM) in FAU’s College of Engineering and Computer Science have received a $100,000 grant from the City of Miami Beach to test two adaptive traffic signals being considered for one of their busiest corridors in South Beach – Arthur Godfrey Road (41st Street). Miami is among the 10 U.S. cities with the worst traffic. In addition, FAU’s LATOM recently received a $300,000 grant from the Florida Department of Transportation to research use of high-resolution data, from signal controllers and detectors, to monitor performance of traffic signals.

“Timing for research in adaptive control systems is right and perspectives are exciting,” said Mohammad Ilyas, Ph.D., dean of FAU’s College of Engineering and Computer Science. “With better sensing technologies such as wireless communication and personal mobile devices, smarter algorithms, and more processing power, we are moving towards an era of much more efficient, safer and eco-friendly traffic signals.”

These complex systems require extensive surveillance and communication infrastructure to enable connection either among local controllers or between a central system and the local controllers. FAU’s LATOM is a one-of-a-kind simulation lab equipped with software, hardware and institutional capabilities, providing regional, national and international partners with opportunities to develop new and use existing methods and tools to monitor, manage and control transportation infrastructure.

“Congested roads have long been a headache for contemporary cities and we need to look at innovative ways to deal with traffic,” said Aleksandar Stevanovic, Ph.D., PE, director of LATOM and associate professor in FAU’s Department of Civil, Environmental and Geomatics Engineering. “While better management of traffic signals won’t reduce the number of cars on our streets, we can do a much better job in adjusting signals to work more efficiently.” He adds, “Smart traffic lights are one way to address urban traffic congestion, and if timed properly and continually, they can both reduce traffic delays and improve public safety.”

Conventional signal systems use pre-programmed, daily signal timing schedules. Adaptive traffic control systems on the other hand, adjust the timing of red, yellow and green lights to accommodate changing traffic patterns. Duration of the green lights is usually a result of a complex compromise between the needs of a single intersection and the needs for good connection/progression with other surrounding intersections. Adaptive traffic control systems create such compromising solutions ‘on the fly’ by extensively using wires embedded in city streets, or other forms of detectors, to sense changes in traffic demands and its patterns.

As a relatively new technology, adaptive control systems are still somewhat expensive. Therefore, municipalities often seek advice from experts and research labs to pre-test effectiveness of these systems in the lab environment before the systems are deployed in live traffic.

“In our lab, we are able to work with our partners to model or ‘simulate’ different traffic patterns throughout a day – and on weekends and during various other scenarios – where virtually the same technology that controls traffic in the field is used in simulation to test its effectiveness and reliability,” said Stevanovic.

According to the U.S. Department of Transportation, on average, smart traffic lights improve travel time by more than 10 percent, and in areas with particularly outdated signal timing, improvements can be 50 percent or more.
