Some problems with new LED street lights

Posted on by

Many communities have installed LED bulbs in public areas but the rollout hasn’t always gone smoothly:

For some, those first LED lights have been a fiasco. The harsh glare of certain blue-rich designs is now thought to disrupt people’s sleep patterns and harm nocturnal animals. And these concerns have been heaped on the complaints of astronomers, who as far back as 2009 have criticized the new lights. That’s the year the International Dark-Sky Association, a coalition that opposes light pollution, started worrying that blue-rich LEDs could be “a disaster for dark skies and the environment,” says Chris Monrad, a director of IDA and a lighting consultant in Tucson…

Lately, lighting companies have introduced LED streetlights with a warmer-hued output, and municipalities have begun to adopt them. Some communities, too, are using smart lighting controls to minimize light pollution. They are welcome changes, but they’re happening none too soon: An estimated 10 percent of all outdoor lighting [PDF] in the United States was switched over to an earlier generation of LEDs, which included those problematic blue-rich varieties, at a potential cost of billions of dollars…

Whatever their faults were, those blue-rich LED lights do save energy and money. My city of Newton, Mass., which has about 80,000 residents, expects to save US $3 million over 20 years after swapping its 8,406 sodium streetlights for 4,000-K LEDs, and avoid 1,240 metric tons of carbon dioxide emissions annually. Los Angeles anticipates saving $8 million a year after installing more than 150,000 LED streetlights, [PDF] while New York City hopes to recover $14 million a year by replacing the city’s 250,000 streetlights with LEDs.

Outdoor LEDs also illuminate streets more efficiently than sodium not so much because of their superior lumens per watt but because they are highly directional, meaning that they focus light mostly in one direction. Sodium lamps are gas-filled bulbs that emit in all directions. More than half of that light must be redirected downward by reflectors or lenses, reducing the lamps’ illumination efficiency.

It sounds like the solution is already at hand: swapping early LEDs for later ones that have warmer hues. Yet, this could serve as a cautionary tale of what happens when infrastructure changes: something that many people don’t pay attention to (street lights) suddenly changes and the world (literally) looks different. Of course, the savings are tremendous but infrastructure choices shouldn’t always be made solely due to efficiency: many residents also care about quality of life and have certain expectations about how things are lit.

While on this topic, it reminds me that I would like to eliminate fluorescent lights in buildings. Rather than use them in my office, I often don’t have my lights on. Maybe I’ve fallen prey to conditioning regarding enjoying yellower incandescent light. Given the changes in bulbs across all sorts of settings, we might all prepare for a future of harsher and colder light.

Leaders of global cities coalesce around common interests

Posted on by

This doesn’t have to be framed as Trump versus big cities to be interesting: leaders of global cities have common perceptions about the world.

That was the important message of the visit by Khan, who arrived in New York after an earlier stop in Chicago. Like his hosts, Democratic mayors Bill de Blasio in New York and Rahm Emanuel in Chicago, Khan forcefully insists that integration, inclusion and openness to the world offer the best chance both to defuse terror and maximize economic growth.

That perspective shared by the mayors of almost all large U.S. cities and many others in Europe views immigrants as a source of economic and cultural vitality, trade as an engine of prosperity, and integration of Muslim communities as the central defense against radicalization and terror. “We play straight into the hands of the extremists and terrorists when we [say]…it’s not possible to hold Western values and to be a Muslim,” Khan wrote last week in the Chicago Tribune. “It makes it easier for terrorists to radicalize young people. And it makes us all less safe…”…

Adjusting for national differences, the mayors of global cities are largely coalescing around agendas antithetical to the Trump vision. “There are 50 cities, maybe 100, that are the intellectual, cultural and economic engine of the world,” Emanuel said in an interview shortly after Khan left Chicago. “We are all working on the same things because we face similar opportunities. We have to make our cities competitive. The jobs and companies we talk about are not only global but mobile.”

This modern urban agenda revolves around investment in infrastructure and education (ranging from expanded pre-school to tuition-free post-secondary education); welcoming immigrants; support for small business and information-age technology start-ups; promoting more dense development (Khan toured Chicago’s impressive riverfront development as a possible model for the Thames); embracing renewable energy as both an economic engine and environmental imperative; and with only a few exceptions (like deBlasio) supporting more international trade. The common theme, Emanuel says, is to create a “platform for private sector growth” while advancing equity and inclusion.

This could be used as evidence for limiting or eliminating the nation state, at least for the most powerful cities of the world. If anything, nations might hold them back from doing what they really need to do. Similar arguments have been made recently about states enacting new laws that supersede regulations from cities. See an overview here.

For the sake of public argument, it would be helpful to see the positive argument made for why cities need or benefit from states and countries. Outside of helping to balance budgets, what would Rahm Emanuel say is the benefit for Chicago of being part of Illinois as opposed to operating as an independent entity? Or, could Khan explain why London is a better place because of being in England and the United Kingdom?

High housing prices drive more people to live in vans

Posted on by

When housing prices are high, residents adapt in a variety of ways:

He’s not alone. Last year, 4,600 cars and RVs were used as homes, according to The Los Angeles Times…

“The main expenses are insurance for the van, which is like $60 a month,” said Hutchins. “Then, I have a storage unit for like $60.”

That puts his monthly rent at $120. The van cost him just $125 at an auction…

Hutchins works part-time at a Taco Bell to help pay the bills, and he says living in a van has slashed his cost of living by $800 a month.

He showers at the gym, cooks on a portable stove on a sidewalk (he stores his butane at his friends’ place nearby) and uses wifi at nearby coffeeshops.

Four quick thoughts:

  1. I assume this is more attractive for younger adults who are starting their careers. Even with all the buzz about tiny houses and having smaller and more sustainable settings, I can’t imagine too many people with more established careers choosing this.
  2. Traditionally, Americans like cars. This seems like a clever adaptation for people who can make it work (see #1): you have some people and it is mobile.
  3. How do municipalities view this? The article mentions that this is not against the law in Los Angeles though there may be issues with parking in different places. At the same time, how many communities would want to have significant numbers of people living in vehicles?
  4. It would be helpful to get more data on this: is this a viable option only when housing prices are really high or is this a choice made for additional reasons as well? Does the weather in LA make this easier?

Reducing trespassing on railroad tracks

Posted on by

Experts from several areas are working to limit the number of people on railroad tracks:

Trespassing numbers have remained fairly steady over the years and now account for about 72 percent of all railroad-related deaths, with 761 fatalities in 2015, including 296 suicides.

Safety experts are now focused on finding ways to cut trespassing through education, intervention and barriers such as fencing at popular trespassing spots. But advocates concede it won’t be easy — there are 140,000 miles of railroad track in the United States, and it is impossible to contain it all.

“Trespassing has been more of a stubborn problem for us,” said Bonnie Murphy, president and CEO of Operation Lifesaver, a national train safety organization, who spoke along with other safety experts at the biennial DuPage Railroad Safety Council conference last week. “There’s a disturbing, ongoing trend of people walking along the tracks.”

This is an important safety issue. But, it raises a larger question: while the lines are technically private property, how do you realistically keep people off of them when they crisscross all parts of America at ground level? Railroads rejected the idea long ago that fences should be built along the thousands of miles of lines. There is no mention in this article of enforcing trespassing but I assume this would require a significant amount of resources. Cameras at important locations? Warning signs at regular intervals along the lines? Trains using a more effective warning signal of their arrival (think of a targeted rumbling option from a longer distance)? More effort at moving rail traffic away from major population centers (such as going around major metropolitan regions when possible)?

Railroads can be incredible at moving freight and people long distances. However, they don’t interact well with pedestrians.

A few fake LA lawns watered as CA drought continues

Posted on by

The lawn may be so culturally powerful that fake lawns need to be watered:

But a CBS Los Angeles investigation found the water has not stopped flowing outside DWP buildings. Rather, the DWP has installed sprinklers to soak its fake grass for minutes at a time…

On a recent Thursday morning, sprinklers ran for six minutes, soaking fake grass outside the South LA substation. Even an area completely devoid of grass — real or fake — was inundated by water from sprinklers.

The excess water ran down the sidewalk and toward the street in an apparent violation of city code stating, “No customer of the Department shall use water in a manner that causes or allows excess or continuous water flow or runoff onto an adjoining sidewalk, driveway, street, gutter or ditch.” Such runoff is prohibited even for recycled “gray” water.

I realize that this story appears to be driven less by concern for water supplies – which are an ongoing issue in California – and more about neighbors expressing anger that they have to conserve water lest they be fined while the city appears to be wasting it. In other words: big government should follow its own rules. This could be a microcosm of national politics.

Yet, could there be a good reason for watering the fake lawn?

“We’re rinsing the grass to make it more sanitary,” said Richard Harasick, director of water operations at the DWP…

“We’re really just trying to wash out dog pee,” he said.

So it is dogs that utilize the fake lawn. Who knew that even replacement lawns need so much regular maintenance due to regular use. (Some need to be painted.) And getting people to stop their dogs from using the replacement lawn may be difficult.

Perhaps a solution here is to get rid of the fake lawn entirely. A common sight in recent years in California is to use lawns replaced with other features like drought resistant plants or stones. There was even a rebate program implemented for this as the state aimed to replace a lot of turf.

One takeaway to this story: it is hard for Americans to get rid of lawns as well as reactions to their use and maintenance.

What exactly does “Death Knell Tolling for McMansions” mean?

Posted on by

Numerous outlets are sounding a similar theme: Death Knell Tolling for McMansions. Most of this seems to be based on one recent study that said the cost premium McMansions used to command has declined. Does this mean McMansions are in decline? Not necessarily. There are many ways this could turn out including:

  1. McMansions are still built and bought and sold. Even if they don’t command as much money as before, they still might be profitable.
  2. Over the coming years, fewer McMansions are built and the ones that are constructed are primarily in thriving communities (lots of money as well as population growth).
  3. Regardless of whether #1 or #2 happen, there are plenty of existing McMansions. They could go (1) like many other older American homes – altered, remodeled, passed from groups to groups; or (2) they are so undesirable or shoddy that they are replaced by other housing options. The second option is hard to imagine; plenty of postwar houses are still in existence and it would be costly to destroy a lot of housing units.

Even if fewer McMansions are constructed in the future, they aren’t simply going away. Some McMansions will be around for 50+ years.

Sociologist on the effect of skylines on cities

Posted on by

Camilo Jose Vergara is a sociologist and photographer who in a recent piece showing multiple angles of the World Trade Center tower over the decades also remarks about the power of a city skyline:

“The skyline is often how people relate to cities,” Vergara told The Huffington Post. “If a city has a skyline, it enters into a different category. It’s a grand city, a great city.”

Two points are notable:

  1. Cities are complex so an iconic image – the skyline – can be an important shorthand for the large city and metropolitan region.
  2. Important cities have notable skylines. Of course, many cities have taller buildings that can be seen from a distance. But, only certain cities have large collections of tall buildings and these skylines can have buildings that becomes iconic in themselves.

In other words, it is hard to imagine major American cities without recognizable skylines. Yet, European cities don’t have the same obsession with skyscrapers and tend to feature older structures like churches. And I wouldn’t be able to immediately pick out a skyline for Tokyo or Berlin or Moscow or New Delhi.

Trying to convert large empty grocery stores to better uses

Posted on by

The end of a company can have rippling effects: a number of Chicago area communities have been working for years to fill empty Dominick’s stores.

When Dominick’s went out of business in December 2013, it added 72 empty stores to the Chicago area’s retail landscape. The most desirable ones were snatched up by chains like Jewel-Osco, Mariano’s and Whole Foods Market. Last year, Albertsons acquired Safeway, Dominick’s parent company, giving it control of most remaining Dominick’s leases and property in the area.

At least 18 suburbs are still trying to turn the lights back on in the darkened stores. As time drags on, the prolonged vacancies create pockets of blight in once-thriving retail areas, hurting town coffers, hindering other businesses and inconveniencing residents. Some officials blame Albertsons, saying the company is paying rent on dark buildings to block out Jewel-Osco competitors…

Albertsons has been “extending dark store leases” to keep out competition, a tactic that’s “objectionable, but not unusual” in the Chicago area’s extremely competitive grocery industry, said Andrew Witherell, a commercial real estate broker who consulted with Mariano’s on its expansion into 11 former Dominick’s stores…

Other towns have banded together to attract retailers. Last year, nine western suburbs launched a joint effort, “One Call/10 Stores,” to try to fill some 700,000 square feet of former Dominick’s space. Most of those stores, however, remain empty.

In other words, there is little incentive for Albertsons to sell the properties. I would also guess that a number of suburbs have struggled to find tenants who could use all of the building space and possibly be there for a long time. In many places, is there really a need for another grocery store given all the options (and with Walmart operating as the biggest grocery chain in America)?

Perhaps some of these communities need to head in different directions. Break the large store into smaller pieces. Think about retrofitting the whole structure to include a mix of uses and alter the big store and large parking lot dynamic. Maybe demolishing the structure could provide a fresh start and entice someone who doesn’t want to be saddled with an aging large structure. It will be interesting to see how long communities will go before trying something more drastic.

The Swiss Cheese Model for dealing with industrial accidents

Posted on by

I was recently reading The Grid by Gretchen Bakke where a discussion of massive power plant brownouts led to discussing two approaches to industrial accidents:

One might be given to think that this blackout might have been prevented if somebody had just noticed as things slowly went awry – if in 2002 all of FirstEnergy’s “known common problems” had been dealt with rather than merely 17 percent of them, if the trees had been clipped, if a bright young eye had seen the static in the screen. But what most students of industrial accidents recognize is that perfect knowledge of complex systems is not actually the best way to make these systems safe and reliable. In part because perfect real-time knowledge is extremely difficult to come by, not only for the grid but for other dangerous yet necessary elements of modern life – like airplanes and nuclear power plants. One can just never be sure that every single bit of necessary information is being accurately tracked (and God knows what havoc those missing bits are wreaking while they presumed to-be-known bits chug along their orderly way). Even if we could eliminate all the “unknown unknowns” (to borrow a phrase from Donald Rumsfeld) from systems engineering – and we can’t – there would still be a serious problem to contend with, and that is how even closely monitored elements interact with each other in real time. And of course humans, who are always also component parts of these systems, rarely function as predictable as even the shoddiest of mechanical elements.

Rather than attempting the impossible feat of perfect control grounded in perfect information, complex industrial undertaking have for decades been veering toward another model for avoiding serious disaster. This would also seem to be the right approach for the grid, as its premise is that imperfect knowledge should not impede safe, steady functioning. The so-called Swiss Cheese Model of Industrial Accidents assumes glitches all over the place, tiny little failures or unpredicted oddities as a normal side effect of complexity. Rather than trying to “know and control” systems designers attempt to build, manage, and regulate complexity in such a way that small things are significantly impeded on their path to becoming catastrophically massive things. Three trees and a bug shouldn’t black out half the country. (p.135-136)

Social systems today are increasingly complex – see a recent post about the increasing complexity of cities – and we have more and more data regarding the components and the whole of systems. However, as this example illustrates, humans don’t always know what to do with all this data or see the necessary patterns.

The Swiss Cheese Model seems to privilege redundancy and resiliency over stopping all problems. At the same time, I assume there are limits to how many holes in the cheese are allowed, particularly when millions of residents might be affected. Who sets that limit and how is that decision made? We’ll accept a certain number of electrical failures each year but no more?

Exploring why Americans think their children are at such risk

Posted on by

Virginia Postrel summarizes a recent study looking at how Americans perceive the safety of children:

The researchers suspected that overestimating risk reflects moral convictions about proper parenting. To separate the two instincts, they created a series of surveys asking participants to rate the danger to children left alone in five specific circumstances: a 2 1/2 -year-old at home for 20 minutes eating a snack and watching “Frozen,” for instance, or a 6-year-old in a park about a mile from her house for 25 minutes. The reasons for the parent’s absence were varied randomly. It could be unintentional, for work, to volunteer for charity, to relax or to meet an illicit lover.

Because the child’s situation was exactly the same in all the intentional cases, the risks should also be identical. (Asked what the dangers might be, participants listed the same ones in all circumstances, with a stranger harming the child the most common, followed by an accident.) The unintentional case might be slightly more dangerous, because parents wouldn’t have a chance to make provisions for their absence such as giving the child a phone and emergency instructions or parking the car in the shade.

But survey respondents didn’t see things this way at all. “A mother’s unintentional absence was seen as safer for the child than a mother’s intentional absence for any reason, and a mother’s work-related absence was seen as more dangerous than an unintentional absence, but less dangerous than if the mother left to pursue an illicit sexual affair,” they write. The same was true for fathers, except that respondents rated leaving for work as posing no greater danger than leaving unintentionally. Moral disapproval informed beliefs about risks…

“People don’t only think that leaving children alone is dangerous and therefore immoral,” the researchers write. “They also think it is immoral and therefore dangerous. That is, people overestimate the actual danger to children who are left alone by their parents, in order to better support or justify their moral condemnation of parents who do so.”

This reminds me of the trolley problem. While it doesn’t deal with risk, it hints at how morality is involved in assessing situations. Good parenting today includes avoiding intentional absences (and even these can be ranked). Leaving a child for unintentional reasons is not so bad. Both are of equal risk – just as saving five lives in the trolley problem regardless of how it is accomplished – but not viewed the same.

Generally, we have difficulty these days estimating risk. Are we more in danger from a possible terrorist attack (limited risk) or getting into a car (one of the riskiest daily behaviors)? We don’t always assess situations rationally nor do we have all the information at our fingertips. I don’t know that the answer is to suggest we should be more rational all the time: this is difficult to do and may not even be desirable. In this particular case, it might be more prudent to explore where these ideas of morality come from and then work to alter those. Alas, this is also likely a lengthy task.
