Good question: “What Will Happen to Public Transit in a World Full of Autonomous Cars?”

Posted on by

The fate of mass transit is unclear in a world of all autonomous cars:

The question of what they’ll mean for transit was actually on the program this year at the Transportation Research Board annual meeting in Washington, where several thousand transportation officials and researchers met to talk about state-of-the-art asphalts, biker behavior, and the infrastructure of the future. In one packed session, I heard Jerome Lutin, a retired longtime New Jersey Transit planner, say something that sounded almost like blasphemy.

“We’re just wringing our hands, and we’re going to object to this,” he warned the room. “But the transit industry needs to promote shared-use autonomous cars as a replacement for transit on many bus routes and for service to persons with disabilities.”…

The implication in this raises (at least) two more questions: Exactly where (and when) will it make sense for people to use buses or rail instead of autonomous cars? And if autonomous cars come to supplement these services, should transit agencies get into the business of operating them? In my initial daydream – where shared self-driving cars are whisking us all about – it’s unclear exactly who owns and manages them.

Lutin sounds skeptical that transit agencies will be able to move into this space. “They don’t adapt well to change,” he says. They’re also governed by rigid mandates that limit what they can do. A mass transit agency can’t overnight start operating something that looks like a taxi service. Public agencies also must contend with labor unions, and labor unions likely won’t like the idea of replacing bus routes with autonomous cars.

This does seem to trade a public good – mass transit paid for by taxpayers and users – for private goods, autonomous cars owned by individual users. While we haven’t seen prices for driverless cars yet, I can’t imagine they are going to be too cheap at the beginning. Even a less appointed driverless car, say a Chevrolet Aveo, is going to need more complicated gadgetry to be autonomy. But, as this planner notes, Americans do tend to like more private transit options if they can afford it.

Driverless cars might lead to the safest roads ever seen and highways that actually work

Google’s Sebastian Thrun discusses the safety advantages of driverless cars as well as effective highways in this video. Two quick thoughts:

1. Autonomous vehicles can help stop the wave or accordion pattern of driving where someone slowing down at the front of a line of cars backs everyone up. Thrun talks about a a much more closely coordinated zipper kind of merging where cars going basically bumper to bumper can accept new vehicles with little change.

2. Even with a dip in recent years, more than 30,000 Americans die each year in vehicles. Strun says most of this is due to driver error, which can basically be eliminated when humans no longer control the car.

All of this sounds good…

Argument: Christie case drawing so much attention because commuting affects so many people

Posted on by

Here is an interesting take on Chris Christie’s predicament: it is getting so much attention because commuting matters to a lot of people.

New York City Councilman Jimmy Van Bramer just published this chart of the breakdown of constituent service requests and complaints his office fielded during 2013 (“no problem is too small for us to handle,” Van Bramer writes in his annual report card):

How we get around has an enormous influence on our quality of life, and so it’s central to what we expect from our elected officials. This is why unplowed roads can undermine an entire administration. It’s why arcane changes to residential parking permit policy stir such public ire. It’s why problems with transportation make up the largest single set of concerns that a local city councilman must address – beyond even jobs, public safety, and housing.

This is also why New Jersey Governor Chris Christie is in such trouble. Were he neck-deep in a petty political spat involving a public park or a job-training program or a real-estate project, the scandal wouldn’t resonate quite so widely. We often talk about transportation – and its sub-genres of parking policy, street design, traffic management and mass transit planning – as a niche interest of nerds at the national level. Locally, though, no issue is more politically potent.

Don’t mess with the commute of the average American. It might be much worse because driving is involved because driving usually implies more independence and privacy. On the other hand, when mass transit is at fault, like it has been this past week with Metra in the Chicago area, there is less that the individual commuter can do. Uncontrollable situations are bad enough but intentional sabotage of commuting would infuriate all commuters.

Watch out for the “stroad,” the bad street/road hybrid

Posted on by

A former street engineer provides warnings about the “stroad” and the havoc it wreaks on the landscape:

“The STROAD design — a street/road hybrid — is the futon of transportation alternatives. Where a futon is a piece of furniture that serves both as an uncomfortable couch and an uncomfortable bed, a STROAD moves cars at speeds too slow to get around efficiently but too fast to support productive private sector investment. The result is an expensive highway and a declining tax base.”

Marohn says he coined the term in 2011 to wake up the people who design America’s roads. “I really was writing it as a way to push back at the engineering profession and get my fellow engineers to think about the bizarre things they’re building,” says Marohn. That was why he initially wrote the word in that annoying all-cap style, which he eventually dropped. “I figured engineers would read it and wonder, what was it an acronym for?” he says, laughing.

While Marohn came up with the neologism partly in a spirit of fun, he considers stroads a deadly serious problem. Not only are they dangerous and aesthetically repugnant, he argues that they are economically destructive as well. They don’t provide the swift, efficient mobility that is the greatest economic benefit of a good road, and they simultaneously fail to deliver the enduring value of a good street — which fosters community, good architecture, and financial resilience at the lowest possible cost…

Instead, stroads create hideous, inefficient, and disposable environments that quickly lose value.

These are many of the four to six-lane commercial thoroughfares that dominate American cities, at least the less dense parts, and suburbs. These roads are lined fast food restaurants, big box stores, car dealers, gas stations, offices, and big signs that try to catch your attention as you drive by. One twist that I like here is the suggestion that this is not necessarily good for cars either because of all the traffic lights and congestion.

Two places where I have seen depictions of such stroads:

1. I recently showed the documentary Jesus Camp in class and the film features several scenes of such roads. The roads don’t look very attractive – lots of cars and signs – and they are sort of stand-ins for everyday Americana. It is one thing to see it in a film and another to realize that you drive past this every day. But, as the film suggests, America is filled with these scenes and they all kind of look similar.

2. James Howard Kuntsler, a well-known critic of sprawl, makes a note of such roads. In different contexts, he points out the absurdity of trying to be a pedestrian on such a road that is clearly meant for cars (imagine crossing all those lanes at a traffic light or walking through all of the drives in and out of business) as well as the trivial amount of “nature” that planners try to add in to make it all look better. All together, these roads just encourage sprawl.

What is the alternative to this? In a perfect world, perhaps it is connecting denser downtowns and neighborhoods with pedestrian friendly streets (nodes) with a system of faster roads or mass transit (connections between the nodes).

“Have We Reached Peak Road?”

Posted on by

With the decline in driving, perhaps it is time to consider whether we have reached peak road:

At his Transportationist blog last week, University of Minnesota scholar David Levinson pointed out that Department of Transportation estimates of public roads and street mileage in the United States — paved and unpaved alike — leveled off between 2008 and 2011 (the latest year given, with data missing for 2009 and 2010). Levinson charted the plateau (the y-axis mileage is in thousands)…

Like vehicle miles traveled, paved road mileage steadily increased for decades, from roughly 1.23 million miles in 1960 to 2.6 million in 2011. (Unpaved roads followed the opposite trend, declining over time as many became paved.) The paved peak might have occurred in 2008, when mileage reached above 2.7 million. The 2011 mileage, meanwhile, is about the same as that of 2005.

Given that the statistical peak coincided with the Great Recession, it’s probably too early to call things. It’s also important to keep in mind that there are multiple ways to measure a road. There is its end-to-end length (known as “centerline miles”) and there is also its total capacity (known as “lane miles”) — the latter calculated by multiplying the length by the number of lanes….

Levinson thinks the following factors will guide whatever subsequent shifts occur in centerline and lane miles: rural gravelization (converting paved roads into unpaved ones to reduce maintenance costs), tearing down urban freeways, designing complete streets and implementing road diets, and converting general lanes into exclusive bus lanes. Even further ahead, autonomous cars should enable cars to use the existing roadway far more efficiently.

I wonder how much this is tied to sprawl and population growth. Opponents of sprawl would want denser cities and suburbs and this doesn’t necessarily require adding new roads. But, expanding metropolitan regions can lead to new roads and highways.

The call here to use existing roads more efficiently ignores one overarching concern that may be on the mind of a number of local officials as well as taxpayers: who is going to pay for new roads? Here are the pieces involved:

1. Building the roads in the first place. If these roads are constructed in dense areas, the costs rise sharply in order to purchase land. If major roads are desired, we may see more public-private partnerships or toll roads.

2. Maintaining the roads for a long period of time. These costs include everything from filling potholes to adding capacity to complete rebuilds.

If we have reached peak road, perhaps we should continue to celebrate the massive highway building project the United States embarked upon and successfully completed in the second half of the 20th century.

One final thought: when exactly can we declare peak anything? If the data shows not much change over an eight year period, is this enough knowledge to predict no more future growth? I would be very hesitant to stake a lot on such a claim…

Jaywalkers vs. car culture in downtown Los Angeles

Posted on by

The battle for Los Angeles may not involve aliens but rather jaywalking pedestrians versus cars in downtown Los Angeles:

It is not quite “Dragnet,” but the Police Department in recent weeks has issued dozens of tickets to workers, shoppers and tourists for illegally crossing the street in downtown Los Angeles. And the crackdown is raising questions about whether the authorities are taking sides with the long-dominant automobile here at the very time when a pedestrian culture is taking off, fueled by the burst of new offices, condominiums, hotels and restaurants rising in downtown Los Angeles…

The police say they are simply trying to maintain order at a time when downtown Los Angeles, once a place of urban tumbleweeds and the homeless, is teeming with people competing for pavement with automobiles. “There’s a huge influx of folks that come into the downtown area,” said Sgt. Larry Delgado of the Central Traffic Division. “If you go out there, you are going to see enforcement.”

These pedestrians are confronting not only the police, but a historically entrenched car culture that has long defined the experience of living and working in Los Angeles. With its wide streets, and aggressive motorists zipping around corners, cutting in and out of lanes and sneaking past red lights, Los Angeles is hardly built for people who prefer to walk.

Yet times may be changing. There are an increasing number of people using bicycles, taking advantage of an expanding network of bike lanes. Los Angeles is in the midst of a major expansion of its subway and bus system. Much of the urban planning in recent years, particularly downtown and in Hollywood, is intended to encourage people to give up their cars in favor of public transit, walking or biking.

It is hard to tell what exactly is going on here without some hard data about jaywalking fines in downtown LA over time. However, it does make for an interesting narrative: while many cities and places are trying to encourage more pedestrian and bike use (for its green, health, congestion, and other benefits), Los Angeles is cracking down on walkers. The issue is that LA is perhaps the prototypical car city in the entire world. The sprawling city has traditionally not had a downtown on the scale of other major cities that people would want to crowd. The metropolitan area seems to stretch on forever, crisscrossed by numerous highways. This is home to the Beach Boys singing about driving, the rise of fast food, and lots of car commercials.

Jaywalking may be an opening skirmish but this could blossom into a longer war over the heart of Los Angeles: is it really a city about cars or can it also contain dense, walkable nodes? Critics of sprawl would see a Los Angeles full of pedestrians (at least in pockets) as a tremendous success story.

Natural gas bus commercial misses that riding the bus is already helping the environment

Posted on by

This commercial from America’s Natural Gas Alliance highlights natural gas buses in Los Angeles. The message is that the natural gas buses are better for the environment. They may be – but it misses the point that individuals using mass transit are already helping the environment (let alone traffic congestion). So having a natural gas bus is a bonus. Perhaps we would all be better off if more people were willing to ride any kind of bus in the first place.

However, given that it is difficult to get wealthier people to ride buses, we should then ask when we might have cars powered by natural gas. If natural gas is cleaner to burn, why not reduce the emissions from cars rather than focusing on the limited number of Americans who regularly ride the bus?

(I realize the natural gas buses may just be a marketing ploy. However, it is really about helping the environment, not good PR or trying to sell more natural gas, why not use natural gas to power more things?)

Chicago’s once-thriving streetcar system

Posted on by

Like many American big cities, Chicago once had a large streetcar system:

Those cable cars were preceded by horse-drawn streetcars, which began service in 1859, and were replaced by electric-powered trolleys, beginning in 1890. By the mid-1930s, 3,742 streetcars were running on tracks laid along 529 miles of streets in a grid that provided Chicagoans a streetcar stop within a few blocks of where they lived, worked or shopped. Trolley wires extended into vast areas of the Northwest, Southeast and Southwest sides far from the nearest “L,” making it the adventurous Chicagoan’s system of choice for exploration…

For their part, aldermen and legislators knew the value of changing a “no” to a “yes” vote on a streetcar-line franchise. Each innovation in motive power brought with it safety concerns, upon which politicians could hang a price tag for overcoming their reservations.

The advantage of streetcars compared to the “L” or railroads, both of which helped make Chicago famous, was that it could cover more land and fill in the development gaps between the more infrastructure intensive types of transportation. While the streetcars were eventually replaced by cars, which could serve the same function and allow drivers more independence and privacy, streetcars helped kick off mass suburbanization in the late 1800s.

See more about Chicago streetcars here on this page about Chicago Surface Lines which operated Chicago’s streetcars until 1947. According to this, Chicago had quite the system that quickly went from peak to bust:

The continuous reorganization was finally completed by the Unification Ordinance of 1913, which stipulated that all lines would come under the management of a single operating association called the Chicago Surface Lines (CSL), and unified operations commenced in 1914. Four companies formed the CSL: the Chicago Railways Company, Chicago City Railway, Calumet and South Chicago Railway, and Southern Street Railway. At this time, Chicago had the largest street railway system, the longest one-fare ride, the longest average ride, and the most liberal transfer privileges in the world.

The 1920s saw continued growth despite the increasing competition from the automobile, and while the 1933-1934 World’s Fair and wartime demand supported ridership, the underlying companies were bankrupt. Creditors’ bills were filed against the Chicago Railways in 1926 and the Chicago City Railway and Calumet and South Chicago in 1930, resulting in the appointment of receivers and bringing their property into the custody of the Federal District Court. In 1944, the proceedings were converted to those under the Bankruptcy Act, and trustees were appointed. By 1958, the Chicago Transit Authority, which took over the Chicago Surface Lines in 1947, had abandoned the remaining trolley lines, which were “bustituted.” Before that, CSL had introduced gasoline buses for light routes in 1927,and trolley buses to the northwest side starting in 1930.

In Crabgrass Frontiers, a classic on American suburbanization, historian Kenneth Jackson gives reasons for the decline of streetcars: the automobile started taking away customers and many streetcar lines were locked into municipal contracts that didn’t allow them to raise fares even as they needed money to maintain infrastructure and compete with the automobile.

Why is Midway nowhere close to the food options of O’Hare?

Posted on by

Eater rates the restaurants at O’Hare and Midway Airports and it isn’t even close: O’Hare is a lot better. Here is the top 8 at O’Hare:

1. Tortas Frontera;  2. Wicker Park Sushi Bar; 3. Wolfgang Puck Cafe; 4. Berghoff Cafe; 5. La Tapenade; 6. Big Bowl; 7. Beaudevin; 8. Garrett Popcorn.

City institutions plus big names at O’Hare. In contrast, the top 8 at Midway seem like what you would find at a shopping mall food court:

1. Manny’s; 2. Potbelly; 3. Pegasus on the Fly; 4. Harry Caray’s Seventh Inning Stretch; 5. Lalo’s; 6. Gold Coast Dogs; 7. Reilly’s Daughter

Perhaps there are some good reasons for this like more passengers at O’Hare (the 6th most passengers in the world), more space at O’Hare (more and bigger terminals plus more passengers provides more room for restaurants while Midway has one food court and then some scattered small options), and a wider range of passengers at O’Hare (Southwest dominates Midway, more first-class and international passengers at O’Hare). One way to boost Midway’s profile would be to improve these food options. It is the smaller airport and has more budget flight options but it was the first passenger airport in Chicago and has a unique place as such an urban airport in a global city.

But, knowing that this is Chicago, I wonder how much food contracts differ between the two airports. Even as O’Hare is more lucrative, why doesn’t Midway have any major name or food choice? Harry Carey’s might have the biggest name recognition (ironic it is located in the South Side airport) but it isn’t exactly known in the restaurant world for great food. Is there something odd about how restaurants at these airports are chosen?

The Pyongyang Metro

Posted on by

What does the subway look like in North Korea? See pictures here.

The underground stations are ornate but dimly lit: patrons squint to read posted newspapers while patriotic music echoes faintly across the stone floor. Most of the 16 public stations (there are rumors of secret, government-use-only networks) were built in the 1970s, but the most grandiose halls – Puhoong and Yonggwang – were constructed in 1987. Mosaics and metallic reliefs extolling the virtues of North Korean workers and landscapes line the walls.

The subway cars were acquired from Germany, and despite a green and red makeover, the remnant graffiti scratched into windows and paneling belies their past lives. And as with every other public and private space throughout the country, portraits of past leaders Kim Il-Sung and Kim Jong-Il look down from the ends of each car, smiling and ever-present.

It would be interesting to hear more about the number of people who use this system and what parts of the city are served. In theory, shouldn’t more socialistic/totalitarian states have better mass transit systems? Countries that emphasize individualism and consumerism, like the United States, might be more open to transportation options, like cars, that support or enable these values. But, countries that have more communal or equality rhetoric could pour more resources into methods that would help move great numbers of people efficiently.
