It Must Be the Fault of the Pedestrian

By Dom Nozzi

October 7, 2017

A century ago, as Peter Norton points out in his book Fighting Traffic, nearly all of us would blame a motorist in a crash that injured or killed a pedestrian or bicyclist.

But today the situation is reversed.

The knee-jerk response in our age is to blame the pedestrian. To blame the victim. It is akin to blaming a woman for being raped because she dressed “too provocatively.” Or was walking alone at night.

In the very rare instances when a community decides to use effective tactics to reduce the number of times a motorist kills a pedestrian (by, for example, designing the street to obligate slower, attentive driving), many motorists will scream “WAR ON CARS!!” This creates an enormous political obstacle to the creation of a safer transportation system.

Such WAR ON CARS! screamers conveniently forget that tens of thousands of pedestrians are killed by motorists every year. And that not a single motorist has ever been killed after being hit by a pedestrian.pe

Sounds more like a war on pedestrians to me…

I refer to “effective” tactics to improve safety, because nearly all US cities are guilty of spending the past century using, over and over again, ineffective tactics: More safety signage. More safety lighting. More safety paint. More safety education. And more safety enforcement.

Since our roads are now more dangerous than ever following a century of repeatedly doubling down on those ineffective tactics, maybe it is finally time to realize that these conventional safety tactics are a failure.

The Time to Prioritize Transportation Safety is Now

By Dom Nozzi

As a member of the Boulder Transportation Advisory Board, I am alarmed by the recent uptick in serious injuries and deaths caused by vehicle crashes on roads in our area. The number is inexcusable.

One of the most common requests by citizens to our Board, the Transportation staff, and City Council is the need to reinstate the neighborhood traffic calming program that was defunded in the late 1990s. Speeding, cut-through vehicles are a serious problem for a great many neighborhoods. Such traffic discourages bicycling and walking; substantially increases noise pollution; endangers our most vulnerable (seniors, children, and pets); is a primary cause of loss of neighborhood quality of life; and fuels opposition to infill development.

What caused this state of affairs?

For several decades, we have been so successful in providing for fast, unobstructed travel by car that it has substantially undermined transit ridership, walking, and bicycling.

Many who venture out on a bicycle are soon reminded by an impatient motorist that she’s in the way and doesn’t belong there. “Danger” is an all-too-frequent reason given in surveys for not bicycling.

Wide travel lanes and multi-lane roads exert a nearly irresistible influence over a motorist. Even motorists who are not inclined to drive fast creep up to highway speeds. Amplifying this problem: large numbers of drug- or alcohol-impaired drivers, sleep-deprived drivers, and time-starved drivers. These factors are a dangerous mix, as they induce a great deal of high-speed, inattentive, reckless driving.

Making a street “safer” too often tends to increase vehicle speeds, which makes the streets less safe. One result: a disproportionate number of serious injuries and deaths in Boulder are suffered by pedestrians and bicyclists. About 40 percent of all children killed in motor vehicle crashes are killed while walking or riding a bicycle.

Measured by “years of life lost,” motor vehicles fatalities rank third. Since 1930 (!), over 30,000 Americans die in motor vehicle crashes annually.

Motorists are more likely to collide with pedestrians at higher speeds. At 60 miles per hour, the field of vision of the motorist is two-thirds less than at 30 miles per hour. In addition, the probability of a pedestrian being killed is only 3.5 percent when a vehicle is traveling at 15 miles per hour, but jumps to 37 percent at 31 miles per hour and 83 percent at 44 miles per hour.

Roadway geometry in safety-sensitive areas, such as schools, needs to keep speeds near 20 miles per hour.

Portland finds that traffic circles are most effective when constructed in a series. They are sometimes also located in the middle of the block. Circles reduce motor vehicle speeds. Circles reduce crashes by 50 to 90 percent, when compared to two-way and four-way stop signs and traffic signals, by reducing the number of conflict points. Seattle likes circles so much that they were building about 30 circles each year a few decades ago.

Despite the conventional wisdom, stop signs do not affect overall speeds or control speeding. Posting lower speed limits and enforcing them is not sufficient to achieve needed reductions in speeding. Modest physical reconfiguration of streets is the only reliable and cost-effective way to slow and control inattentive speeding.

Calming helps reduce neighborhood noise pollution. From a distance of 48 feet, a car traveling at 56 miles per hour makes ten times more noise than a car traveling at 31 miles per hour. Reducing average speed from 25 miles per hour to 12 miles per hour reduces noise levels by 14 decibels (ten times quieter). At higher speeds, every 12 to 15 miles per hour in speed increases results in a 4 to 5 decibel noise increase.

The Federal Highway Administration (FHA) notes that the importance of reducing traffic speed cannot be overemphasized, and has stated that traffic calming is one of the more cost-effective ways to promote pedestrian and bicycle use in urban and suburban areas, where walking and bicycling are often hazardous and uncomfortable. And as for children, Stina Sandels, a world authority on children and road accidents, says that the best road safety education cannot adapt a child to modern traffic, so traffic must be adapted to the child.

Fortunately, there are effective street design tactics to substantially increase road safety, and these methods can be deployed without significantly slowing emergency vehicle response times.

I urge Council to restore funding for neighborhood traffic calming (by adding new dollars rather than shifting existing dollars from the current city transportation budget). Since the City does not have the authority to introduce safe, speed-slowing designs on larger state roads, I urge Council to lobby the State legislature to give Boulder the authority to do so, as well as to stiffen penalties for driving infractions.

I also recommend more compact development in appropriate locations, sponsoring a transportation safety speaker series, and more street connectivity.

We have a duty to make Boulder streets much safer. Let us not delay doing so.

Why Are Traffic Deaths So Barbarically High?

By Dom Nozzi

February 21, 2017

It is inexcusable that when we look at traffic fatalities — and the all-too-common call to reduce the number of fatalities with “safer” cars — we ignore the huge number of bicyclists and pedestrians killed by motorists.

As my op-ed in the Boulder (Colorado) Daily Camera noted recently, despite a century of “redoubling our efforts” every few years to make our roads safer for cyclists and pedestrians, our roads are the most dangerous than they have ever been. Adding more road caution signsWARNING signs, WARNING paint, WARNING education, WARNING enforcement, and WARNING lights (as Boulder is once again proposing to do this year) has done nothing meaningful to make roads safer (many persuasively argue such things make our roads LESS safe).

But I’ll ignore cyclist and pedestrian deaths for the time being.

It is quite common for someone to point to an increase (or decrease) in traffic fatalities suffered by motorists and their passengers over the past year as indicative of a long-term trend – and what has allegedly caused the “trend.” But statistical principles and the complexity of transportation inform us that taking a one-year data point – and then applying a single variable to explain it – is highly unlikely to be accurate. Not nearly enough time has elapsed. And there are way too many variables when it comes to transportation.

An extremely important question I want to ask, rather than trying to explain a one-year change in fatalities, is why motorist deaths have been barbarically high for so long. The US has suffered over 30,000 traffic deaths per year since the 1930s.

And no one seems to care, when we compare concern about traffic deaths to the hysteria about drugs and terrorists and communists…

How have we gotten to this state of affairs?

First, the vast majority of motorists/Americans/elected officials have one objective that is light years more important than safety or quality of community: SPEED. Anything that slows motorists down — such as traffic congestion, road diets, traffic calming, etc. — must be furiously fought against with any and all means necessary.maxresdefault

Even in allegedly enlightened and progressive Boulder, free-flowing, high-speed car travel is head and shoulders above almost anything else as a measure of quality of life.

This single-minded focus explains why cities such as Boulder have a huge number of roads that have way too many travel lanes. Anything more than 3 is incompatible with a quality city, yet Boulder has many roadways (stroads, as Chuck Marohn would call them) that are in the 6- to 12- lane range. Anything more than 3 or 4 lanes is inevitably a recipe for a huge number of car crashes and fatalities.

More of the same thing all American communities have been doing for a century — more WARNING signs, more WARNING paint, more WARNING education, more WARNING enforcement, and more WARNING lights — will do nothing to make such monster roads anything other than on-going death traps.

Yet this same old song and dance is precisely what Boulder proposes to do as it rolls out its exciting “new” objective called “Toward Vision Zero.”

Excuse me for not being optimistic about Boulder not achieving this objective.

A related problem for almost every city — including Boulder — is the century-long use of the “forgiving road” design paradigm, which “forgives” the motorist for driving too fast or not paying attention. Using the “forgiving street” strategy, we remove street trees, make intersections and turn radii crazy big in size, create “super-elevations” at road turns, remove on-street parking, eliminate mid-block pedestrian crossings, move cyclists onto off-street paths, pull buildings away from the street and street corners, etc.

The result?

For several decades, we’ve had an epidemic of excessive speeds and inattentive driving. A great way to ramp up the death toll.

Most cities – to enable easy, high-speed car travel — have followed the path Boulder has taken over the past century regarding land use patterns by keeping densities at ridiculously low levels and strictly separated houses from shops and jobs and offices.

The result?

Distances to daily destinations are extremely lengthy, which makes it impossible for all but a tiny number of people to make ALL trips by car. That guarantees a large number of annual motorist deaths, as driving a car is inherently very dangerous — due to the fact that cars are heavy, large, able to achieve high speeds, and substantially reduce the sense of hearing and sight that a motorist has outside of a car.

One example of a destination that is now nowhere near any homes is an iconic social gathering place: the pub. Unlike in past times, it is now almost impossible to walk or bike home after having a few beers. Inevitably, that means a lot of people are driving in an inebriated state.

The “forgiving street” design paradigm has so substantially increased inattentiveness that a huge number of motorists now drive inattentively at high speeds. Again, a great way to ensure a huge number of motorists crashing and dying.

Americans are extremely busy – probably a lot more so than in the past – and the motor vehicle provides a way to save time: drive very fast. Oops. Another way to kill people in car crashes.

Solutions? The effective tactics are nearly impossible to achieve in almost any city – including Boulder — where 98 percent of the population will fight to the death to stop these safety measures from being enacted:

  1. More compact, mixed-use land use patterns so that travel distances are short enough to make walking and bicycling feasible for most people and most trips.
  2. Toss out the forgiving street paradigm in favor of designing streets that obligate slower, attentive driving.
  3. Substantially shrink the size of nearly every road and intersection.road diet before and after

But each of these essential tasks (if we are serious about achieving Vision Zero) is utterly off the table – not even something that one is allowed to mention in “polite society.”

Much of what I advocate in transportation is an “off the table” topic. My friend Jim Kunstler just pointed out that this “elephant in the bedroom” syndrome has a name. It is called the Overton Bubble.

http://thefutureprimaeval.net/the-overton-bubble/

In sum, because we are probably decades away from having the political will to opt for effective street safety methods, we will continue to see over 30,000 American motorists die every year for the remainder of our lives.

After all, speed — not safety — is what we sincerely seek.

Promoting Traffic Safety

 

By Dom Nozzi

August 20, 2016

After three years of trying, I have finally been given the opportunity to give a presentation to the Boulder transportation advisory board – of which I have been a member. The topic will be on traffic safety, and I will be making the presentation in either early September or early October.

I decided one point I’d like to make is that if anything, streets have become much less safe than they were in the past – despite decades of often aggressive, extensive, expensive boulder-traffic-safetysafety efforts. This morning, I looked for a chart showing the trend in the number of annual deaths on US roadways. I have included a few charts from Wikipedia in this blog. “Annual Traffic Deaths” shows the crazy high number of annual deaths.

But the “Annual Deaths Per Mile Driven” chart shows that we are making a lot of progress on safety! I was surprised and realized I’d have to revise my presentation.

Then I came across a “Traffic Deaths” essay.

I learned from the essay that several decades ago, the auto folks needed to find a way to address the great alarm on the part of many Americans when they saw the huge number of traffic deaths. The solution to this PR problem – to head off serious efforts to reduce car dependence in our society – was to convey deaths based on MILES DRIVEN. It turns out that applying “miles driven” as a way to measure deaths is quite misleading. After all, if we used miles traveled, the space shuttle would be the “safest” way to travel…

Using that metric, the auto folks were able to reduce alarm (and meaningful efforts to reduce car dependence), because the metric shows improving traffic safety. Now we can sidestep the thought that 30,000 to 40,000 traffic deaths per year is barbaric (and demands our society reduce car use) and instead focus safety on individual motorist mistakes or mechanical solutions (which does almost nothing to correct this shocking, unacceptable road carnage problem).

One of my points about traffic safety is that our forgiving roadway design induces dangerous and growing levels of inattentive driving and excessive speeding. I believe inattentive driving and speeding are epidemic mostly because of our decades of employing forgiving roadway design. But if this is true, why does the chart show a decline in deaths since 1970?

My explanation is that while roads ARE more dangerous today than in the past, much of the reduction in deaths is associated with making cars (and, therefore, the motorists bike-car-crash1inside them) safer with such things as seat belts, air bags, and aggressive efforts against drunk driving – not to mention our removing a lot of trees and other “hazards” from near the side of roads.

I found another chart that shows a big increase in bicyclist deaths since the 1970s. That can partly be explained, I guess, by the growth in cycling since then, but I think it is also compatible with my belief that roads are more dangerous today. Motorists are safer in certain ways, but the growth in inattentiveness and speeding are leading to motorists killing more people bicycling.

In sum, it is clear to me that our roads need to be substantially redesigned to obligate slower, more attentive driving by motorists through various traffic calming, as well as reductions in the size of roadways and intersections. More warning signs, warning lights, warning paint, warning education, and warning enforcement has utterly failed to make our streets safe.

It is way past time to get serious and redesign our appallingly dangerous roadway system.
