The dangers of distracted walkers

Posted on by

Watch out for those texting pedestrians:

Distracted walking is most common among millennials aged 18 to 34, but women 55 and older are most likely to suffer serious injuries, including broken bones, according to a 2013 study in Accident Analysis & Prevention. Visits to emergency rooms for injuries involving distracted pedestrians on cellphones more than doubled between 2004 and 2010 and continues to grow. Among more than 1,000 people hospitalized after texting while walking, injuries included a shattered pelvis and injuries to the back, head and neck.

According to the National Safety Council, “the rise in cellphone-distracted walking injuries parallels the eightfold increase in cellphone use in the last 15 years.” Although the council found that 52 percent of distracted walking episodes occurred at home, the nationwide uptick in pedestrian deaths resulting from texting while walking has prompted the federal government to offer grants of $2 million to cities to combat distracted walking…

Alas, most people seem to think the problem involves other people. They’re not the ones who walk distracted. A new survey of some 6,000 people released last week by the American Academy of Orthopedic Surgeons, found that while 74 percent said that “other people” were usually or always walking while distracted, only 29 percent said the same about themselves. And only 46 percent considered the behavior “dangerous.”

I don’t do this much myself for two reasons. First, it slows my walking speed down. I’d rather get to my destination quicker and then text. Second, I generally don’t like impeding pedestrian traffic, whether the issue is texting, stopping for a conversation, gawking, etc.

Maybe the best solution – hinted at in the end of the article – is to be a defensive pedestrian in the same way that you are supposed to practice defensive driving. Be alert. Look around. Be aware of pedestrians and other possible obstacles. Have an alternative action in mind should others not respond appropriately.

Perhaps we should have a talking and texting lane for those who want to engage in this?

A fast lane for walkers in a Liverpool shopping complex

Posted on by

Fast movers get their own walking lane in a new experiment outside Liverpool stores:

Argos has painted new markings on the pavement outside its Liverpool store after research revealed almost half the nation found the slow pace of high streets to be their biggest shopping bugbear.

The new lane, being trialled this week in the Liverpool One shopping complex, hopes to help pick up the pace for those who are hurrying by bypassing the crowds.

New statistics show 31 per cent of people find pavement hoggers frustrating, while more than a quarter (27 per cent) get annoyed by dawdling pedestrians…

‘As the research demonstrates, a faster high street could vastly improve the overall shopping experience for British shoppers across the UK.

As a fast walker, I approve. However, I envision multiple problems arising:
  1. The speed of fast walkers could vary quite a bit from each other. Various people could be moving faster than the general population but still not be moving fast enough for others in the fast track.
  2. What happens when people inevitably wander into the fast track without knowing?
  3. Where is the proper entrance and exit ramp on this track? This isn’t exactly like a moving walkway that has a clear beginning and end. Come to think of it, why not install more moving walkways that can help everyone move faster through a main corridor like this? (It does look like this is an outside setting so that’s an issue.)

How long can this experiment last? While there are a lot of pedestrians on many city streets, I’ve never seen fast lanes like this before.

What if car-free central Paris catches on?

Posted on by

It is a day for pedestrians in Paris:

“Parisians will be able to take back their daily living space and experience the city in a different way,” said Mayor Anne Hidalgo, who would have liked to make the entire city off-limits to vehicles on Sunday.The closure is unprecedented for the French capital and opens the entire city center to pedestrians only for one day, expanding on popular areas already off-limits to Sunday traffic like the fashionable Marais, the cobblestoned Montmartre and the hip neighborhood along Canal Saint-Martin.

Bumper-to-bumper traffic that normally clogs the city’s boulevards will be replaced by street parties, yoga classes, markets with fresh produce and — this being Paris — food tastings with top chefs…

Paris’ motor-free day is by no means a world’s first. Brussels, the traffic congestion capital of Europe, launched its first car-free Sunday 15 years ago, an example followed by Montreal, Jakarta and other cities.

The rest of the article emphasizes the pollution cars regularly bring to Paris and an upcoming climate change conference. These are important matters to address but there are also quality of life issues at well. Like many older cities, Paris has been retrofitted to accommodate cars and vehicles but what can be done is limited. Central Paris is a place for pedestrians, even after Haussmann’s changes, for both locals and tourists. The congestion tax in central London is an adaptation to a similar setting.

All together, I’m interested in what happens after this car-free day happens: do people find that they like this more than they thought? Why not regular car-free Sundays and then perhaps additional days as well? Yes, this could help bring down pollution levels but it could also make the central city a more pleasant place. Given the spread of such days in major cities throughout the world, I wouldn’t be surprised if we see more such days in Paris.

Signs to slow down for children are not recommended

Posted on by

Despite the well intentioned efforts of parents, posting signs instructing drivers to slow down for children do not help:

While Smith’s actions came from a protective place, his efforts may be fruitless, as there’s little evidence to support the effectiveness of advisory signs in regard to changing driver behavior or making children safer. In fact, the National Cooperative Highway Research Program firmly discourages the use of signs that read “Caution — children at play” or “Slow — Children.” One reason, points out Slate, is common sense. “If the driver does not notice the characteristics of a neighborhood as they drive down the street, why would they notice a sign as they pass it, or remember it for more than a few seconds once they have passed it?” an engineer from an online forum noted on the website.

There’s also the possibility that a sign emphasizing the presence of children in one location may imply that an absence of warning would mean no kids are present in another. And finally, such warnings could falsely convey that the street is a play area. The same principle applies to neighborhood stop signs, which encourage drivers to actually speed up in between them.

One proposed solution:

“It largely comes down to awareness,” Janette Fennell, founder and president of KidsAndCars, a nonprofit safety organization, tells Yahoo Parenting. “Drivers often have an ‘It can’t happen to me’ mindset when speeding, and most people overestimate their driving skills.” But lowering the speed limit even a little helps reduce the number of accidents and increase the survival rate of victims, according to research published by the AAA Foundation for Traffic Safety. “I’d estimate that a person is about 74 percent more likely to be killed if they’re struck by vehicles traveling at 30 mph than at 25 mph,” study co-author Brian Tefft told Wired.

Here is a better solution as even speed limits can only do so much: more road diets. In many places, streets are far too wide for what is needed for typical traffic. This gives drivers the impression that they have a margin of error. And, having nothing in their path – ranging from speed bumps to stop signs to parked cars – only contributes to driving faster. If you really want people to slow down when driving through residential neighborhoods, we should: (1) narrow streets, (2) have regular street parking, and (3) plant trees closer to the roadway. All of these things would give drivers more consistent indicators that they can’t drive as fast. Drivers may not like this as it feels more closed in and they have to pay attention more (will someone open a car door? How far do I get over if a car is coming from the opposite direction?) but it will slow them down.

Making these changes would take a major effort as many streets have been built extra-wide for decades. Yet, we have often privileged the car when designing roads and one of the consequences is faster driving and increased risk for pedestrians and others utilizing roadways.

A more radical solution that wouldn’t require changing many roads? Promoting driverless cars that closely control how fast vehicles move.

Mexico City’s pedestrian superhero back in the news

Posted on by

Continuing to fight for pedestrians in Mexico City is “The Little Pedestrian”:

The mighty Peatonito (Little Pedestrian) pushes cars blocking the path of pedestrians, creates crosswalks with spray paint, and climbs on vehicles parked on sidewalks — though his mother has begged him to stop stepping on them.

“Pedestrians are happy because they finally have a defender,” Peatonito said, his face covered by a wrestling mask adorned with a pedestrian symbol and wearing a striped cape (sewn by his grandma) adorned with the black and white stripes of a pedestrian crossing.

“We live in a car dictatorship. Nobody had fought for pedestrian rights until some activists emerged a few years ago.”

Meanwhile, below the city streets five clowns are on a similar mission to send up urban incivility, barging into a metro carriage making monkey noises and holding a sign saying “It’s better without pushing.”…

Peatonito aims to reduce traffic deaths in a city where pedestrians account for more than half of around 1,000 annual road fatalities, according to health ministry statistics.

This is a fascinating way to draw attention to the issue. It is one thing to publish statistics or to have more road signs (read about the campaign in Illinois to post the number of driving deaths for all to see) but another for a handful of people to act in public spaces. With the line of “we live in a car dictatorship,” I’m surprised others haven’t taken up similar routines in other cities around the world (including the United States which might be as much as a car dictatorship as one can have). But, two things might be problematic:

1. I wonder if police or local officials could actually arrest them for being a disturbance. In a real car dictatorship, you don’t want fake superheros running around in the way of cars. Might it take some complaints from drivers or others who feel that these crusaders have gone too far?

2. How does one translate these activities into a broader social movement or changes in policies and regulations? If the pedestrians of Mexico City wanted to take over the roads, they certainly could. At the least, this superhero might publicly shame the city but that doesn’t necessarily lead to large-scale change.

By the way, this isn’t the first time Peatonito has drawn international news coverage. See this story from 2013 that discusses what his actions led to:

Peatónito is the alter ego of Jorge Cáñez, a 26-year-old political scientist in Mexico City who has also worked with the Institute for Transportation and Development Policy (ITDP)…

His efforts got him invited to speak at the Walk 21 conference in 2012 and has met with officials from Mexico City’s department of public security to discuss the importance of putting pedestrians first in street design and traffic enforcement. He is hopeful about government efforts to improve infrastructure. At least, he says, they are now talking about giving pedestrians priority — which would only make sense in a city where 80 percent of the population doesn’t drive…

“Once the government has adopted the ‘pedestrian is the king’ in their speeches, I’m going to monitor and help them till the day there’s no pedestrian fatalities nor accidents, and also decent sidewalks and safety crossings in the streets. But even if the government calls me to collaborate, I will always be a non-partisan citizen hero of the public domain.” He has registered Peatónito as Creative Commons, so that anyone who wants can become Peatónito.

Perhaps there really are superheros…

Wheaton’s walkable shopping center…surrounded by parking lots

Posted on by

Renovations are coming to the Town Square Wheaton shopping center yet the picture of the complex shows it may just be as auto dependent as any shopping center:

It features 160,000 square feet of retail space, much of it filled with chain stores such as Banana Republic, Gap, Joseph A. Bank, Starbucks, Yankee Candle and Talbot’s. The property also includes two professional buildings that house medical offices.

Tucker Development plans to enhance the seven buildings arranged in a walkable loop primarily through signage and facade improvements.

Town Square Wheaton, a shopping center on the south side of the city, recently was sold for nearly $57.3 million. The new owner, Tucker Development, has plans for $1 million in renovations.

This shopping center embodies a lot of the features of newer lifestyle centers or New Urbanism-inspired shopping centers: it features a central plaza with a walkable loop around it, the scale is not huge, there are office spaces on the second floor plus numerous eateries (mixed uses), and it borrows from a local architectural style (Prairie School).

Yet, the overhead view highlights one of the problems that plagues numerous New Urbanist developments: they are often plopped right into car-dependent areas so that even if they are pleasantly walkable, one needs to drive there first. Walking or biking there is not easy; there are apartments adjacent to the center but there is not a permeable boundary between the spaces. You could walk or bike to the center from several nearby single-family home subdivisions (I was just biking near here recently) but that typically requires traveling along and/or crossing busy Naperville Road which funnels a lot of commuter traffic through south Wheaton (the primary path to Naperville and I-88) and isn’t exactly lined with beautiful structures.

Hence, just another shopping center surrounded by parking lots…

The decline in kids walking to school

Posted on by

Several experts talk about the issues with many fewer American kids walking to school compared to fifty years ago. The negative effects? Less exercise, less learning about active transportation, less exploration in and knowledge of their own neighborhoods.

I suspect many people will blame parents and kids for this and tell them to simply walk and stop being lazy/decadent/unnecessarily scared/etc. However, it is not as if many Americans regularly walk places outside of major cities and denser neighborhoods. Some of this may be due to comfort but other factors are involved including nicer vehicles, more fear about crime, more sprawl (particularly in the Sunbelt) which means further distances and fewer pedestrian-friendly streets, less emphasis on physical activity in daily life (which is not necessarily laziness but rather more sedentary lives overall), and a shift toward technology (starting with television) rather than active exploration. In other words, this is likely a multifacted problem that is not easily solved by simply “making” kids walk.

The “particle” rules governing human interactions in crowds

Posted on by

A group of physicists suggests humans follow particular rules while interacting in crowds:

Skinner and his coauthors, a pair of computer scientists at the University of Minnesota, looked at six data sets that capture individual movements in crowded places: four from natural settings, like video footage of pedestrians on a college campus, and two from laboratory experiments, in which participants were tracked with cameras as they navigated a corridor that narrowed into a bottleneck. Such data sets have become available only in the last five years, as improvements in camera technology and the field of computer vision have made large-scale pedestrian tracking possible.

Initially the researchers assumed they would find a “repulsive force” between people, like the one that pushes charged particles apart. As they looked closer, they realized it wasn’t that simple: There was a repulsive force between individuals, but it only operated sometimes. “Two people walking head first into each other have a strong interaction,” Skinner says, “but people walking side-by-side have almost no interaction.”

So the researchers went looking for a new rule. They found it in a variable they called “time to collision,” which explained many of the course adjustments they observed. The closer two people get to colliding, the more energy they expend getting out of each other’s way. To be technical, they found that the interaction between individuals in a crowd could be described as 1 over the square of the time to collision: As a collision becomes more imminent, the energy you apply to avoiding it goes up drastically.

Unlike with particles, the mechanism that produces these adjustments is an instinctive mental calculation rather than any kind of physical force. There’s also a limit to how far out we can—or need—to account for other people’s movement. When the time to collision was more than three seconds, the researchers found that the interaction energy between two pedestrians fell to zero, meaning people weren’t taking each other into account at all.

This seems to apply mainly to areas where people are going opposite directions, whether in an open concourse at a stadium or a crowded city crosswalk with two masses of people trying to get past each other. In these situations, there is usually an area of stronger flow on each side but then in the middle – between the two larger flows – is a zone where such collisions are imminent. I know because I often walk in such zones when in a hurry. It can be difficult in those situations to avoid people and not everyone likes to walk in such high-stakes areas where there is a higher probability of bumping into people.

The article goes on to talk about applications of these findings. I would guess that means having more clearly marked traffic flows and trying to avoid the weaker flows or neutral areas that I mentioned.

Smartphones can turn urban dwellers into zombie pedestrians

Posted on by

What happens when urban residents and visitors are engrossed in their smartphones? It can lead to zombie pedestrians.

But the growing ranks of these cellphone addicts are turning cities like Tokyo, London, New York and Hong Kong into increasingly hazardous hotspots, where zombified shoppers appear to be part of vast games of human pinball…

Tokyo Fire Department, which runs the ambulance service in the megalopolis, says that in the four years to 2013, 122 people had to be rushed to hospital after accidents caused by pedestrians using cellphones.

As well as the vaguely comedic incidents of businessmen smacking into lamp-posts or tripping over dogs, this total also included a middle-aged man who died after straying onto a railway crossing while looking at his phone…

Phone fidgeters dawdling along at snail’s pace, forcing cyclists and pram-pushing mums to swerve out of the way have become such an irritant in Tokyo that public notices have started to appear warning offenders to expect “icy stares”, appealing to the Japanese sense of social harmony — assuming people look up from their phones in the first place.

Smartphone apps activated by sensors that flash warning signs or display the pavement on the screen have also been developed in response to the problem.

An unintended side effect of technological advancement. Walking in a big city can be a dangerous task, particularly given the emphasis in many places on helping cars get to their destinations faster. Things that distract pedestrians – just like things that can distract drivers – can lead to negative outcomes.

It is interesting to note the last piece above that tries to solve a problem created by technology with a technological advancement: just have an app that alerts people. It’s technology all the way down! Would something like Google Glass help get rid of these issues since people would still have their eyes facing forward?

First shared street – devoid of street markings, signs – coming soon to Chicago

Posted on by

This has been tried elsewhere (see this example in England) but the first shared street will be in place next year in Chicago:

The New York Times editorial board recently called the concept of shared streets a “radical experiment” for the city of Chicago, which plans to start construction on its first one on Argyle Street early next year. Yet the philosophy behind them–that by removing common street control features, street users will actually act less recklessly and negotiate space through eye-contact—is actually not all that new. Shared streets have been built and shown to be effective in reducing accidents in London already. In the U.S., shared streets exist in Seattle, Washington and Buffalo, New York.

The Chicago project came about as the city was looking to implement a normal street improvement project for Argyle Street, an active block with businesses and restaurants in a diverse neighborhood where many Vietnamese immigrants settled in the 1970s. The street had also shut down for the city’s first night market for the last two summers, and Alderman Harry Osterman, whose ward includes the area, says officials wanted to continue spurring the revitalization of the area. The lakefront bicycle path is only two blocks away…

The $3.5 million street renovation will feature a design with no curbs or lanes, and minimal signage, though there will be stop signs, so as not to descend too far into chaos. Different colors and pavers will indicate where the sidewalk would normally end and where the street begins; the speed limit will be 15 miles per hour. Overall, the goal is to change the mood of the street: “Psychologically for drivers, they will know that they can’t just shoot from stop sign to stop sign.”

Osterman hopes that as a result of the improvement project, more visitors will come to businesses in the area, and that the open space will make it easier to encourage more sidewalk cafes and temporary events. The city is now nudging existing business to spruce up their facades.

It will be fascinating to see how this plays out in Chicago. Several of the interesting features here:

1. Such designs deemphasize the role of cars. Chicago drivers tend to like to go fast when they can so I suspect they will not like this change.

2. Pedestrians and businesses will probably like this a lot as it can enhance street life, leading to more people hanging around and frequenting the businesses.

3. In looking at the design, I did wonder about parking. If someone wants to drive to this stretch, this change might lead to more parking issues on adjacent blocks.

4. Even if this is successful, will it catch on more widely in Chicago? As noted above, while walkers and businesses will probably like this, you can’t have too many of these street or drivers will be really upset about their limited options.
