Study: wearing hi-viz clothing does not reduce risk of collision for cyclists
Journal of Transport & Health, 22 March 2017:
This study found no evidence that cyclists using conspicuity aids were at reduced risk of a collision crash compared to non-users after adjustment for confounding, but there was some evidence of an increase in risk. Bias and residual confounding from differing route selection and cycling behaviours in users of conspicuity aids are possible explanations for these findings. Conspicuity aids may not be effective in reducing collision crash risk for cyclists in highly-motorised environments when used in the absence of other bicycle crash prevention measures such as increased segregation or lower motor vehicle speeds.

Understanding Uber: It's Not About The App
the next time you see a link to a petition or someone raging about this decision being ‘anti-innovation’, remember Greyball. Remember the Metropolitan Police letter [regarding several sexual assaults which Uber didn't report to police]. Remember that this is about holding ULL, as a company, to the same set of standards to which every other mini-cab operator in London already complies. Most of all though remember: it is not about the app.

Undercover operation 'Close Pass' reduced cyclist injuries by 20% in a year

An initiative to protect cyclists from dangerous overtaking has been praised, after reducing the amount of cyclists killed or seriously injured on the roads by 20% over the last year.
Operation 'Close Pass' was devised by West Midlands Police as a low cost way of preventing accidents caused by motorists who are driving too close for comfort.

Physical separation of cyclists from traffic “crucial” to dropping injury rates, shows U.S. study
Citing a further study of differing types of cycling infrastructure in Canada, the editorial writes that an 89% increase in safety was noted on streets with physical separation over streets where no such infrastructure existed. Unprotected cycling space was found to be 53% safer.

In 2014 there were 902 recorded cyclists fatalities in America and 35,206 serious injuries. Per kilometre cycled fatalities per 100 million kilometres cycled sat at 4.7. In the Netherlands and Denmark those rates sit at 1 and 1.1, respectively.

The Forgotten Story Of The Radium Girls
'The radium girls’ case was one of the first in which an employer was made responsible for the health of the company’s employees. It led to life-saving regulations and, ultimately, to the establishment of the Occupational Safety and Health Administration, which now operates nationally in the United States to protect workers. Before OSHA was set up, 14,000 people died on the job every year; today, it is just over 4,500. The women also left a legacy to science that has been termed “invaluable.”'

New Scientist: Home abortions are safe – we should let women do it themselves
the Women on Web approach is backed by a column in New Scientist:

'It’s also safer than many other medicines that we are allowed to buy from pharmacies without a prescription, such as Viagra in the UK. So why can’t women get abortion pills from pharmacies and manage the process themselves at home if they choose? It might sound radical but it’s already widespread in countries where abortion is illegal, with women buying the pills from online pharmacies. While some countries, such as Poland, are trying to tighten their already strict abortion laws, the advent of mail-order abortion pills means the law is becoming almost irrelevant.'

"Better truck design could save hundreds of pedestrian and cyclist lives"
European transport group, Transport and Environment, said that the Loughborough study shows that better design “could save hundreds of pedestrian and cyclists’ lives”. It added that the study “finds huge differences in the direct vision – what drivers can see with their own eyes – of best and worst-in-class trucks in all categories, and that ‘low-entry cabs’ like the Mercedes Econic out perform all of today’s best performing vehicles.”

A P-Series truck, from truck maker Scania, was rated at the best of its class with zero blind spots — this could go a long way to explaining why the makers of a Road Safety Authority video using another P-Series truck reportedly had to fake blind spots last year.

Mandatory extra mirrors has been EU policy to try to reduce collisions with people cycling and walking but researchers point out that blind spots remain on many trucks and improving direct vision may be a better policy than improving indirect vision using mirrors. [...]

The EU currently has a deadline of 2028 for improved vision in trucks but Transport and Environment said: “Given that better vision cabs are already available on the market and in all market segments (best in class, smarter configurations, low entry vehicles) a 2028 deadline is not justifiable.”

The Problem With Cul-de-Sac Design - CityLab
“A lot of people feel that they want to live in a cul-de-sac, they feel like it’s a safer place to be,” Marshall says. “The reality is yes, you’re safer – if you never leave your cul-de-sac. But if you actually move around town like a normal person, your town as a whole is much more dangerous.”

This is the opposite of what traffic engineers (and home buyers) have thought for decades. And it’s just the beginning of what we’re now starting to understand about the relative advantages of going back to the way we designed communities a century ago.

Marshall and Garrick took the same group of California cities and also examined all their minutely classified street networks for the amount of driving associated with them. On average, they found, people who live in more sparse, tree-like communities drive about 18 percent more than people who live in dense grids. And that’s a conservative calculation.

“I Want to Know What Code Is Running Inside My Body” — Backchannel
Sandler wants to be able to explore the code running her device for programming flaws and vulnerability to hacking, but she can’t. “Because I don’t have access to the source code, I have no power to do anything about it,” she says. In her eyes, it’s a particularly obvious example of a problem that now cuts across much of modern life: proprietary software has become crucial to daily survival, and yet is often locked away from public exploration and discussion by copyright.

Kodak Had a Secret Nuclear Reactor Loaded With Enriched Uranium Hidden In a Basement
non-proliferation? what's that?
Kodak's purpose for the reactor wasn't sinister: they used it to check materials for impurities as well as neutron radiography testing. The reactor, a Californium Neutron Flux multiplier (CFX) was acquired in 1974 and loaded with three and a half pounds of enriched uranium plates placed around a californium-252 core. The reactor was installed in a closely guarded, two-foot-thick concrete walled underground bunker in the company's headquarters, where it was fed tests using a pneumatic system. According to the company, no employees were ever in contact with the reactor. Apparently, it was operated by atomic fairies and unicorns.

Three quarters of cars stolen in France 'electronically hacked' - Telegraph
The astonishing figures come two months after computer scientists in the UK warned that thousands of cars – including high-end brands such as Porsches and Maseratis - are at risk of electronic hacking. Their research was suppressed for two years by a court injunction for fear it would help thieves steal vehicles to order. The kit required to carry out such “mouse jacking”, as the French have coined the practice, can be freely purchased on the internet for around £700 and the theft of a range of models can be pulled off “within minutes,” motor experts warn.

Alarm design: From nuclear power to WebOps
Imagine you are an operator in a nuclear power control room. An accident has started to unfold. During the first few minutes, more than 100 alarms go off, and there is no system for suppressing the unimportant signals so that you can concentrate on the significant alarms. Information is not presented clearly; for example, although the pressure and temperature within the reactor coolant system are shown, there is no direct indication that the combination of pressure and temperature mean that the cooling water is turning into steam. There are over 50 alarms lit in the control room, and the computer printer registering alarms is running more than 2 hours behind the events.

This was the basic scenario facing the control room operators during the Three Mile Island (TMI) partial nuclear meltdown in 1979. The Report of the President’s Commission stated that, “Overall, little attention had been paid to the interaction between human beings and machines under the rapidly changing and confusing circumstances of an accident” (p. 11). The TMI control room operator on the day, Craig Faust, recalled for the Commission his reaction to the incessant alarms: “I would have liked to have thrown away the alarm panel. It wasn’t giving us any useful information”. It was the first major illustration of the alarm problem, and the accident triggered a flurry of human factors/ergonomics (HF/E) activity.

IrishCycle.com on the Irish Times' terrible victim-blaming anti-cycling op-ed
Even if The Irish Times wants to deny that it has engaged in victim blaming at a high level, it has also clearly errored in fact in a very significant way. It would be more forgiving if this was an isolated editorial. But it’s after two days of wrong or misleading coverage, which now seems to be a trend with the newspaper with unbalanced articles or headlines negatively focusing on cycle routes.

HACKERS REMOTELY KILL A JEEP ON THE HIGHWAY—WITH ME IN IT
Jaysus, this is terrifying.
Miller and Valasek’s full arsenal includes functions that at lower speeds fully kill the engine, abruptly engage the brakes, or disable them altogether. The most disturbing maneuver came when they cut the Jeep’s brakes, leaving me frantically pumping the pedal as the 2-ton SUV slid uncontrollably into a ditch.


Avoid any car which supports this staggeringly-badly-conceived Uconnect feature:

All of this is possible only because Chrysler, like practically all carmakers, is doing its best to turn the modern automobile into a smartphone. Uconnect, an Internet-connected computer feature in hundreds of thousands of Fiat Chrysler cars, SUVs, and trucks, controls the vehicle’s entertainment and navigation, enables phone calls, and even offers a Wi-Fi hot spot.


:facepalm:

Also, Chrysler's response sucks: "Chrysler’s patch must be manually implemented via a USB stick or by a dealership mechanic."

Texting at the wheel kills more US teenagers every year than drink-driving
Texting while behind the wheel has overtaken drink driving as the biggest cause of death among teenagers in America. More than 3,000 teenagers are killed every year in car crashes caused by texting while driving compared to 2,700 from drink driving. The study by Cohen Children’s Medical Center also discovered that 50 per cent of students admit to texting while driving.

California Says Motorcycle Lane-Splitting Is Hella Safe
A recent yearlong study by the California Office of Traffic Safety has found motorcycle lane-splitting to be a safe practice on public roads. The study looked at collisions involving 7836 motorcyclists reported by 80 police departments between August 2012 and August 2013.

“What we learned is, if you lane-split in a safe or prudent manner, it is no more dangerous than motorcycling in any other circumstance,” state spokesman Chris Cochran told the Sacramento Bee. “If you are speeding or have a wide speed differential (with other traffic), that is where the fatalities came about.”

A Case Study of Toyota Unintended Acceleration and Software Safety
I drive a Toyota, and this is scary stuff. Critical software systems need to be coded with care, and this isn't it -- they don't even have a bug tracking system!
Investigations into potential causes of Unintended Acceleration (UA) for Toyota vehicles have made news several times in the past few years. Some blame has been placed on floor mats and sticky throttle pedals. But, a jury trial verdict was based on expert opinions that defects in Toyota's Electronic Throttle Control System (ETCS) software and safety architecture caused a fatal mishap.  This talk will outline key events in the still-ongoing Toyota UA litigation process, and pull together the technical issues that were discovered by NASA and other experts. The results paint a picture that should inform future designers of safety critical software in automobiles and other systems.

Why Sweden Has the World's Safest Roads
Nearly half the EU-wide average.
Sweden has also created 12,600 safer pedestrian crossings with features such as bridges, flashing lights, and speed bumps. That’s estimated to have halved pedestrian deaths over the past five years. The country has lowered speed limits in urban, crowded areas and built barriers to protect bikers from incoming traffic. A crackdown on drunk driving has also helped.

Hanging on the telephone – has anyone got it right on the new ban on text driving?
Some good legal commentary on this new Irish law.
There has been much hand-wringing and concern about whether or not the 2014 Regulations prohibit the use of Google Maps or Hailo, for example. They don’t, but this does not mean that drivers should feel free to use non-texting functions of their phones while driving – holding a mobile phone (which could include a tablet) while driving remains prohibited, whatever the use it is being put to. Moreover, offences of dangerous and careless driving and driving without due care and attention could cover a wide range of bad driving, and could include, for example, driving while zooming in and out of maps on your phone or sending stickers on WhatsApp.

Shared Space and other bad junction designs lead to crashes and injuries
Just because something is "Dutch", that doesn't mean it's good. The Netherlands has many excellent examples, but you have to be very selective about what serves as a model. Cyclists fare best where their interactions with motor vehicles are limited and controlled. They fare best where infrastructure ensures that minor mistakes do not result in injuries.

Anywhere that we rely upon everyone behaving perfectly but where we do not protect the most vulnerable, there will be injuries. Good design takes human nature into account and removes the causes of danger from those who are most vulnerable.

Who Is Watching the Watch Lists? - NYTimes.com
it might seem that current efforts to identify and track potential terrorists would be approached with caution. Yet the federal government’s main terrorist watch list has grown to at least 700,000 people, with little scrutiny over how the determinations are made or the impact on those marked with the terrorist label.
“If you’ve done the paperwork correctly, then you can effectively enter someone onto the watch list,” said Anya Bernstein, an associate professor at the SUNY Buffalo Law School and author of “The Hidden Costs of Terrorist Watch Lists,” published by the Buffalo Law Review in May. “There’s no indication that agencies undertake any kind of regular retrospective review to assess how good they are at predicting the conduct they’re targeting.”

Toyota's killer firmware: Bad design and its consequences
This is exactly what you do NOT want to read about embedded systems controlling acceleration in your car:

The Camry electronic throttle control system code was found to have 11,000 global variables. Barr described the code as “spaghetti.” Using the Cyclomatic Complexity metric, 67 functions were rated untestable (meaning they scored more than 50). The throttle angle function scored more than 100 (unmaintainable).
Toyota loosely followed the widely adopted MISRA-C coding rules but Barr’s group found 80,000 rule violations. Toyota's own internal standards make use of only 11 MISRA-C rules, and five of those were violated in the actual code. MISRA-C:1998, in effect when the code was originally written, has 93 required and 34 advisory rules. Toyota nailed six of them. Barr also discovered inadequate and untracked peer code reviews and the absence of any bug-tracking system at Toyota.


On top of this, there was no error-correcting RAM in use; stack-killing recursive code; a quoted 94% stack usage; risks of unintentional RTOS task shutdown; buffer overflows; unsafe casting; race conditions; unchecked error code return values; and a trivial watchdog timer check. Crappy, unsafe coding.

One of those analyses showed that when a human was behind the wheel, Google’s cars accelerated and braked significantly more sharply than they did when piloting themselves. Another showed that the cars’ software was much better at maintaining a safe distance from the vehicle ahead than the human drivers were. “We’re spending less time in near-collision states,” said Urmson. “Our car is driving more smoothly and more safely than our trained professional drivers.”

Two surgeons debate the use of cycle helmets
'I am a neurosurgeon and a cyclist, and I am also married to a dedicated cyclist. I wear a cycling helmet and encourage cyclists to wear one. I don’t find that wearing one impedes me in any way. I am under no illusion that it will save me in the event of a high speed collision with a car or lorry (nothing will), but most cycling accidents aren’t of the high-speed variety.'

versus:

'I am a consultant Trauma orthopaedic surgeon working in Edinburgh and have many years of experience treating cyclists after serious road traffic, cycle sport and commuting cycle injuries. I believe there is no justification for helmet laws or promotional campaigns that portray cycling as a particularly ‘dangerous’ activity, or that make unfounded claims about the effectiveness of helmets. By reducing cycle use even slightly, helmet laws or promotion campaigns are likely to cause a significant net disbenefit to public health, regardless of the effectiveness or otherwise of helmets.'

Generally a lot of sense on either side.

Accident: Ryanair B738 and American B763 at Barcelona on Apr 14th 2011
An accident report concerning a Ryanair flight.

An American Airlines Boeing 767-300, registration N366AA performing flight AA-67 from Barcelona,SP (Spain) to New York JFK, NY (USA), had taxied to the holding point runway 25L and was holding short of the runway.

A Ryanair Boeing 737-800, registration EI-EKB performing flight FR-8136 from Barcelona,SP (Spain) to Ibiza,SP (Spain) with 169 passengers and 6 crew, was taxiing along Barcelona's taxiway K for departure from runway 25L and was maneouvering to pass behind the Boeing 767-300.

A number of passengers on board of the Boeing 737-800 observed the right hand wing of the aircraft contact the tailplane of the Boeing 767-300 and rose out of their seats attracting the attention of a flight attendant. A passenger told the flight attendant, that their aircraft had hit the aircraft besides them. The flight attendant contacted the purser, who instructed her to contact the flight deck, she contacted the flight deck and informed the captain that passengers had seen their aircraft had hit another aircraft. The captain responded however everything was fine and she continued with the takeoff about 2 minutes after the Boeing 767.

Immediately after departure the passengers insisted the flight was not safe and they had collided with another aircraft, one of the passengers identified himself as an engineer. The flight attendant told the engineer that the captain had been informed and had told everything was fine. No further information was forwarded to the flight deck.

After landing in Ibiza, while disembarking, the passengers again spoke up claiming the flight had been unsafe.

During the turnaround the flight attendant informed the purser that one of the passengers observing the collision was an engineer. Neither approached the flight crew however.

Following the return flight FR-8137 the purser talked to the captain and informed her that one of the passengers observing the collision was an engineer.

In the following it was identified that the right hand winglet of the Boeing 737-800 had received damage, the Boeing 767-300 was found with damage to the left hand stabilizer following landing in New York.


According to the story, it appears the AA flight crew were not informed of the potential damage to their plane before or during their transatlantic flight to JFK. (via Juan Flynn)
