Another danger of at-grade RR crossings: bike crashes

Posted on by

One at-grade railroad crossing in Knoxville, Tennessee illustrates the danger such crossings can present to bicyclists:

As many riders know from painful experience, crossing rails embedded in the street is a treacherous undertaking on a bike. There are at least 100,000 at-grade rail crossings in the U.S., not counting city trams and streetcars (which are also notorious for taking down cyclists). But it’s tough to gather data on how many crashes they cause because so few are communicated to the authorities. “The work I looked at, we saw people getting hauled off on ambulances and other things, but very, very few police crash reports,” says Cherry. “There’s a lot of rail infrastructure throughout Tennessee, and I can only imagine how many unreported crashes are occurring statewide or even nationwide.”

That’s part of what motivated Cherry and company to conduct what they call the nation’s first “empirical analysis of rail-grade crossings and single-bicycle crashes.” To them, the problem wasn’t with the cyclists. It was with the roadway design and the fact nobody knows, scientifically speaking, the best way to bike over railroad tracks….

Most experienced riders know the ideal way to do it: As the folks at Bicycling say, cross at a 90-degree angle. That’s the “gold standard” many infrastructure designers strive for. But in cases when the crossing has gaps running in different directions, it might be best to pedal through at 45 degrees. Of course, all this is more complicated when metal tracks are wet, a situation that can turn even a savvy cyclist into a hollering missile directed fast into the pavement…

After pondering a 90-degree crossing that would cost $200,000, partly due to the route being near a river and needing retaining walls, the city and the railroad company settled on a cheaper, roughly 60-degree “jughandle” detour on the side of the street where people were tumbling into traffic. “The total cost was $5,000 for all of that, which is unbelievable, really,” Cherry says. “This has been years in the making, with probably hundreds of crashes there, and it took $5,000 worth of in-house crew time and materials.” (The city later made the path on the other side, located on a greenway, angled to about 60 degrees.)

In addition to bicycles, at-grade crossings are notoriously dangerous for cars and pedestrians. All would do well to pay extra attention when crossing these, even if they are familiar or rarely involve trains. For example, there are several crossings I can think of within a ten mile radius that involve either extra bumpiness, steep approaches, or multiple train lines crossed at once.

While the solution above for bicyclists seems pretty simple, the long-term goal of reducing the number of such crossings is an expensive proposition. It is costly to build bridges and underpasses since in addition to the typical costs of building a bridge or underpass, a solution requires using more land (I recall a proposal to build an overpass in downtown Wheaton that would have obliterated a good portion of the downtown just to provide the necessary ramps) and it can be expensive to construct something while still allowing traffic through (even if roads are closed, trains have a much harder time finding alternative routes).

What it would take to approve Musk’s Northeast Corridor hyperloop

Posted on by

Elon Musk may have verbal approval for his underground hyperloop but there is much more work to be done to get the project underway:

“It means effectively nothing,” says Adie Tomer, who studies metropolitan infrastructure at the Brookings Institution. “The federal government owns some land, but they don’t own the Northeast corridor land, and they don’t own the right-of-way.” Sure, having presidential backing isn’t bad—but it is far, far from the ballgame…

First, you have to get the OK from all the states and cities and municipalities involved. This is essential because Musk promises this Northeast hyperloop will pass through city centers, so he’s counting on tunneling under places where lots of people live and work and play. Judging by the the official responses from local agencies and politicians along the proposed route, this process is not quite underway. “This is news to City Hall,” the press secretary for New York Mayor Bill de Blasio tweeted. Looks like the Boring Company has a lot of boring meetings with public officials ahead of it…

And then there’s the little problem of moolah. Just updating the current Northeast corridor railroad—you know, the one run by Amtrak—to high-speed rail standards would cost an estimated $123 billion. Tunneling will be even more expensive. Musk has promised his boring technology will speed up the construction and bring down costs. But boring will never be cheap, especially in populated areas. Carving less than two miles of tunnel under New York for the Second Avenue Subway took $4.5 billion. Even if this hyperloop were entirely privately financed, it would take lots of zeroes…

By law, projects need to be evaluated for the potential environmental consequences of their construction and operations, to create what’s called an Environmental Impact Statement. Federal agencies generally take a while to prepare these documents: One 2008 study found the average writeup took three and a half years, and some have taken as many as 18. They also cost a lot to prepare—millions and millions in government funds.

That is a lot to take on. I’ve seen suggestions in recent years that the United States is no longer able to tackle needed large infrastructure projects. In the past, large projects could be accomplished such as the intercontinental railroad or Hoover Dam. Today, American projects lean more toward interminable delays and huge cost overruns. In contrast, some other countries do not get bogged down in the same ways. Sure, some of that might require more authoritarian regimes – such as the new Silk Road railroad in China or the growth in Abu Dhabi in the United Arab Emirates – but things get done!

Moving forward, is there a way for a country like the United States to undertake large innovative projects without all the bureaucracy that slows it down? Can we still take risks? Musk’s hyperloop might be a perfect test case: the technology barely exists so it might be an incredible risk. But, the payoff could be tremendous (and not just necessarily for the intended purpose of a new transportation technology but the other helpful pieces that come along the way – including a way forward across multiple governments and requirements).

The price to get your business on those blue highway amenities signs

Posted on by

It is a surprisingly complicated – and possibly costly – process to promote your business on a blue sign along the highway:

Roadside advertising programs are administered by individual states, though specific service signs like the one in the picture above tend to be farmed out to contractors. One of the biggest of these contractors is a company called Interstate Logos, which works with transportation agencies in 23 states to not only install the huge blue panels, but also to work with businesses to run the programs…

But even if your business meets all the requirements, and you’ve submitted your online application, there may be competition from other nearby businesses. As for which of those businesses get to be on the signs, that depends on the state’s policy. Colorado rotates the businesses at the end of each contract year, but other states like Michigan give preference to businesses nearer the highway, while still others like Washington use a first come-first serve (with waiting list) approach…

Typical mainline logo signs are about 48 inches by 36 inches, so based on WSDOT’s ballpark figures, it’s probably safe to figure about $300 to $500 per sign (this agrees with the Lexington Herald Leader’s claim of $1,253 for four logos)…

The sites says that in 2010, Kentucky Logos—contracted by the Kentucky DOT—paid the state $618,904.91. That’s great for the state, but according to the report, of the businesses on the 1,568 signs in the state, only 1 to 2 percent leave annually. So it seems the businesses are happy, too.

America: combining public services (highways) with business opportunities (advertising a select number of places for travelers to spend their money).

More thoughts on these signs:

  1. Why not include signs for big box stores? Places like Walmart or Target or Costco could provide most or all of these amenities in one stop.
  2. I don’t think the signs are as effective in denser areas where there a lot more options as you approach the exit. They can highlight a few options but you can already see a lot more signs in the distance.
  3. The lodging and camping signs seem outdated. How many people now drive down the highway and pick out a hotel at the side of the road? That sign space could be better used for other amenities.
  4. How effective are these advertisements compared to other forms? Does McDonald’s get a bigger return on the blue sign or a forty foot tall arch or a combination of both?

Second Chicago area diamond interchange opens; how many will follow?

Posted on by

Diverging diamond intersection number two in the Chicago region is opening over the course of a week at I-90 and Elmhurst Road:

Essentially, “northbound and southbound vehicles take turns crossing the intersection,” Garrett explained. “They’ll cross over to the other side, which makes all ramp movements unrestricted. There’s no opposing traffic when turning onto I-90 ramps, which means unopposed left turns and unopposed right turns.”…

On Monday, it will switch to two lanes, and two rebuilt I-90 ramps carrying vehicles to and from the east will reopen. Those ramps will handle about 21,000 vehicles daily.

On Tuesday, two new ramps taking traffic to and from the west will debut, accommodating an estimated 12,000 vehicles a day…

Underneath the diverging diamond is a tangle of utility pipes that carry liquids ranging from jet fuel to O’Hare International Airport to drinking water for suburban communities.

The article notes that only a few motorists had trouble on the opening day.

Looking forward: how many of these can we expect to see in coming years or are these a highway interchange fad? The first diamond interchange in Naperville has had some success – see this earlier post. But, drivers tend to be fussy about changing the roadways, whether with a new interchange or through introducing roundabouts. And, I imagine few residents would be happy to rip out old intersections just to put in a new pattern (think of the costs as well as the lost time to increased congestion). Perhaps we might see a few more of these over the next ten years or so but I don’t think they will become the new normal (which also might decrease people’s comfort with them if they encounter them infrequently).

The ongoing difficulty of Chicago suburb to suburb commuting

Posted on by

The Daily Herald’s transportation writer details the difficulties of taking mass transit between Chicago suburbs:

My odyssey was prompted by the annual Dump the Pump Day, which encourages people to embrace public transit instead of driving.

Here’s a recap of the two-hour, 36-minute voyage to work:

• 8:20 a.m.: Boarded a Metra BNSF train in Downers Grove that arrived at Union Station.

• 9:23 a.m.: Caught a Blue Line train to Rosemont after a short walk from Union Station and a fight with a Ventra machine.

• 10:13 a.m.: Arrived at Rosemont and transferred to Pace Bus Route 606 at 10:30 a.m.; reached work at 10:56 a.m.

The tedious reverse commute lasted two hours, 57 minutes.

• 2:49 p.m.: Boarded Pace Bus Route 757 in Arlington Heights en route to the Forest Park Transit Center.

• 4 p.m.: Left on Pace Bus Route 301 headed to Oak Brook Center.

• 5:03 p.m.: Departed on Pace Bus Route 322 to Yorktown Center at 5:23 p.m.

• 5:30 p.m.: Took Pace Bus Route 834. Arrived in Downers Grove at 5:46 p.m.

By car, the trip is typically 30 to 40 minutes in the morning and 30 to 60 minutes in the afternoon, depending on traffic.

There are some easy answers as well as some more difficult discussions. The easy reasons to start:

  1. Mass transit in the region was constructed in an earlier era when many more people wanted to commute from suburbs to the city. The suburb to suburb trip is a product of recent decades.
  2. There is not money to do mass transit in the suburbs. This applies both to constructing mass transit (such as rail options) or attracting riders (with buses) who have too many starting points and endpoints.

But, given that so much commuting is now suburb to suburb, why aren’t there some more consistent options? Two deeper reasons:

  1. Infrastructure – not just mass transit but other systems including water – are in trouble. We are decades behind in providing good infrastructure. If it is any consolation, highway systems aren’t in much better shape as they often wait too long to add lanes or new routes (and it is debatable how successful these efforts are anyway.) It is both a funding and planning issue.
  2. Wealthier suburbs and suburbanites don’t really want mass transit. They don’t want to pay for it and they don’t want certain people coming to their community. They can generally afford driving and they like the freedom (and the exclusivity) it provides.

Overall, there is both a lack of will to build and use mass transit in many suburbs.

The difficulties of thief-proofing a bicycle

Posted on by

A recent summary of bike lock techniques in Citylab were ultimately depressing: determined thieves can get to your bicycle in many different ways.

So what can be done? A few ideas:

  1. Why aren’t there more companies trying to provide solutions? Several innovative ones are presented in the article:

There’s also a prototype called the Skunklock that, when tampered with, sprays chemicals “so disgusting they induce vomit in the majority of cases,” according to its makers. For the well-being of the community, Grajales doesn’t recommend using this one…

When out and about, Oakland bike advocate Francisco Grajales always tries to use BikeLink, a national service that operates stainless-steel lockers around transit hubs and other cyclist-friendly locations. The amenity is extremely cheap, renting lockers for 5 cents an hour, and offers nice protection in the form of cages resembling those that wall off divers from sharks. “I’m willing to walk a half-mile or something to my destination from the BikeLink just for that added security,” says Grajales.

It seems like there is some money to be made here.

2. A somewhat obvious answer is to have more eyes on bike racks and other locations where bicycles are frequently stored. Paid attendants? Security cameras? Bike check-in centers? It seems like some organizations might want to have attendants if they are truly serious about promoting bicycle use.

3. Perhaps municipal bike-sharing systems – like Divvy in Chicago – can be more widespread. It is not as convenient as having your own bicycle from door to door but the costs of protecting and maintaining the bikes is done by the city or company.

Subways: “New York City is the demented spin-off of Settlers of Catan”

Posted on by

The New York subway system has some problems:

New York City subway service isn’t consistently bad. It isn’t consistently anything. It mixes days of normalcy with surprise disasters whose disruptive effect is something like an air-raid drill, leaving hundreds of thousands of people stranded underground, while their kids wait at schools, their office chairs sit empty, and their shifts begin. If, as former New Jersey Transportation Commissioner Jack Lettiere once put it, transportation is “the game board upon which the economy is played,” New York City is the demented spinoff of Settlers of Catan. The board changes every day, with a debilitating effect on businesses, birthday parties, and everything in between.

That delays have tripled in four years, that subway ridership is declining, that bus ridership is plummeting—these things should alarm Gov. Andrew Cuomo, who runs the Metropolitan Transportation Authority and bears ultimate responsibility for its failings, despite his protests otherwise….

Last Monday, the MTA announced a six-point plan to address delays. “Decades of underinvestment … has led to a system that is excessively vulnerable to failures,” the statement read. (Interestingly, New York has been governed by a Cuomo for 18 of the past 35 years.) The order includes some good news, like the imminent arrival of newer subway cars and deployments of teams to handle broken signals and sick passengers, two major causes of delays. It also appears to have been devised rather quickly—an MTA board member found out about it from the press—and as such, does not account for the subway’s two biggest problems: its ancient signal system and its insanely high construction costs.

Those two things are interrelated and together account for virtually every other problem with the subway. Signals break, hinder the deployment of countdown clocks and driverless trains, and prevent trains from running closer together. High costs impede the development of 20th-century signal technology and other capital improvements, including region-altering projects like the Triboro RX and low-hanging fruit like reopening closed subway entrances. (Read Alon Levy’s excellent coverage of the cost issue and weep.) As long as the MTA fails to address these issues, its troubles will continue.

Bonus points for working Settlers of Catan into a discussion of infrastructure. At the same time, the roads of Settlers might be crazy (particularly when they are blocked by other players) but wouldn’t a better analogy be to a transportation game, perhaps Ticket to Ride?

Seriously though, cities and other levels of government ignore infrastructure at their own peril. It may be easier in the short-term to push off the repairs and costs but the problems only continue to affect users and then are even more costly in terms of money and time down the road.

The roundabout capital of the United States is…

Posted on by

As Chicago area drivers disagree about existing and proposed roundabouts, the roundabout capital of the US is revealed:

Booster Dan McFeely of Carmel, Indiana, wants Illinois to embrace roundabouts.

“We have built 102 roundabouts to date, the most of any city in America,” said McFeely, Carmel’s economic development director. ” … We have steadily added them to Carmel over the past 20 years. They work wonderfully. And yes, we’ve seen a steady decline in accidents with injury.”

Carmel is regularly ranked as one of the best places to live in America. (It just took the #1 spot in Niche.com’s 2017 rankings. It also has done well in Money‘s rankings, taking the top spot in 2012.) Who knew the secret to their success was roundabouts?

As long as there are enough lanes and not so much traffic that people can easily enter the roundabout, I’m all for them. As a driver, I find little worse than traffic lights on timers where you sit for a long period of time with no cross traffic.

One interesting aside from seeing a suburban debate over a roundabout in recent years: they can take up a good amount of room compared to a traditional intersection. Therefore, they might be difficult to implement in older locations or where buildings are relatively close to the road.

Mixing shopping malls and transit centers in Hong Kong

Posted on by

Hong Kong demonstrates a very different model of shopping malls compared to the American suburban mall:

Hong Kong has more than 300 shopping centers, but most of the city’s malls don’t sit on asphalt parking lots; rather, they’re above subway stations or underneath skyscrapers. In my book “Mall City: Hong Kong’s Dreamworlds of Consumption,” I describe how some are connected to so many towers that they form megastructures—cities in and of themselves that can accommodate tens of thousands of people who live, work and play without ever going outside. Hong Kong also has the world’s tallest vertical malls—“mall skyscrapers” that rise up to 26 levels, with crisscrossing “expresators” that shoot shoppers high up into soaring atriums…

As convenient this urban form may be, it does come with strings attached. In the case of Union Square—as in many other podium-tower developments—the mall is deliberately placed at the intersection of all pedestrian flows, between all entry points into the structure and the residential, office and transit areas…

For millions of residents and pedestrians, then, entering commercialized areas becomes an inevitability, not a choice. It normalizes a culture of consumerism: Everyday life is played out on the terrain of the mall, and the private shopping atrium takes on the role of the public square. Because Hong Kong’s apartments are small—its summer climate hot and humid—the mall becomes a default gathering place. And why not? There’s plenty of space and the air-conditioning is free. And while you’re there, you might as well browse around the shops and spend some cash…

The Asian hyper-dense urban mall is also making an appearance in American cities. Miami has Brickell City Centre, a five-story mall in the heart of the city. Covering three city blocks, it’s topped by three high-rises (and was built by a Hong Kong developer). New York City is building a seven-story mall attached to two skyscrapers in Hudson Yards, America’s largest private development. The Santiago Calatrava-designed Oculus—the centerpiece of the World Trade Center—has a mall with over 100 stores, with its white-ribbed atrium attracting an army of tourists taking pictures with selfie-sticks. Since the hub connects office buildings with train and subway stations, the stores are also “irrigated” by the 50,000 commuters who pass by each weekday.

American shopping malls tend to get a bad rap: they take up a lot of space with their endless parking lots, they often require a car in order to get to one, and are centers of consumerism. The Hong Kong malls eliminate two of these major issues: they are a more compact use of space and don’t require cars. Indeed, it is clever to combine mass transit space with a mall. However, these integrated malls may present even larger consumption issues since travelers have to go through these spaces rather than choose to go there. Isn’t this the complaint about gift stores in museums, zoos, or amusement parks where you finish an exhibit or ride and then have to go through the items for sale? And mass transit is supposed to be a public good so it may be a bit strange to mix it so closely with private profit-making. (I wonder if the transit facilities/authorities could take a cut of the sales in these transit malls and funnel more money into transit systems. Is this a way to fund necessary infrastructure maintenance and improvement in the United States?)

I’d love to see an analysis of how sales change when people are intentionally funneled through consumption spaces like this.

Is the Naperville diamond interchange working?

Posted on by

The relatively rare concept of a diamond interchange opened at the Naperville intersection of I-88 and Route 59 in September 2015. Was the effort to reconstruct the interchange worth it?

The short answer: there has not been an official pronouncement. Proponents suggested the design has several advantages: fewer accidents since drivers are not making left turns onto or off of highway ramps, improved efficiency since cars can merge onto ramps on red lights, and less space needed. Here some pieces of evidence regarding the matter:

–The Illinois Tollway is constructing another diamond interchange at I-90 and Elmhurst Road. Would they do this if their first attempt was unsuccessful?

–Crashes at the intersection were down between 2015 (73) and 2016 (53).

-Since it is a busy intersection – over 180,000 vehicles a day – wouldn’t drivers and officials gone public if there were major issues with the new design? Some drivers still thought it odd as of April 2016 but Naperville issues said they were pleased.

–According to DivergingDiamond.com, there are a number of diamond interchanges in the planning or construction stages across the United States.

The evidence seems to suggest the diamond interchange in Naperville is working. It still may be worthwhile to see when officials are willing to take credit or take a victory lap for their decision.
