Cyclists: Let's Talk About Shoaling
You're stopped at a red light with a bunch of folks on bikes, when someone who's just arrived sails past everyone, right to the head of the class. It's a lot like seeing somebody in the Whole Foods express lane with too many things. In other words, it's the kind of behavior that triggers toothy-toddler rages in otherwise emotionally competent adults.


Oh god. This drives me nuts. (via Mark)

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.

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.

Cycling to work: major new study suggests health benefits are staggering
We found that cycling to work was associated with a 41% lower risk of dying overall compared to commuting by car or public transport. Cycle commuters had a 52% lower risk of dying from heart disease and a 40% lower risk of dying from cancer. They also had 46% lower risk of developing heart disease and a 45% lower risk of developing cancer at all.

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.

"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.”

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.

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.”

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.

Only 10% of serious cycling injuries in Ireland were recorded by Gardai
The Bedford Report for the HSE in 2011 showed that only approximately 10% of serious injuries (with hospital admission to a bed) incurred by cyclists in road traffic collisions were recorded by Gardai. If a cyclist is knocked off his/her bike from impact with a motorised vehicle that is a potential criminal offence if serious injury results. Cyclists expect all such RTCs to be properly and fully investigated and recorded with appropriate follow-up. That clearly is not happening at present. Acute hospitals need to document all admission cases arising from cyclist RTCs and inform the Gardai of them.

Call for co-ordinated plan to combat soaring bike theft | Dublin Cycling Campaign
Bicycle theft in Ireland has doubled in Ireland since the introduction of the Bike to Work scheme in 2009. Almost 4,500 bicycle thefts[1] were reported in Dublin in 2013, but the actual number of bike thefts is likely to be in the region of 20,000 in 2013 according to Irish household surveys[2] and international experience[3,4]. The chances of a bike thief being caught is low, with a conviction rate of only 2%[5] or reported thefts. Approximately 230,000 bicycles are imported into Ireland each year[6]. “Bike theft is a low-risk, high-reward crime. If cars were being stolen at this rate there would be uproar.” Says Keith Byrne, Chairperson of the Dublin Cycling Campaign.

Fear of bicycle theft may discourage bicycle use and many bicycle theft victims do not buy a replacement [7,8]. “Many people give up on cycling after their bicycle is stolen and it discourages others from taking up cycling as the word about the high risk of theft spreads. We need a co-ordinated multi-agency plan to tackle bicycle theft if we are to reach the Government target of 10% of journeys by bicycle by 2020” says Keith Byrne.


Amen to that.

'Addressing the rebalancing problem in bike-sharing systems' [paper]
Many of the bike-sharing systems introduced around the world in the past 15 years have the same problem: Riders tend to take some routes and not others. As a result, the bikes tend to collect in a few places, which is a drag for users and a costly problem for the operators, who "rebalance" the system using trucks that take bikes from full stations to empty ones. Now, scientists are coming up with special algorithms to improve this process. One of them, developed by scientists at the Vienna University of Technology and the Austrian Institute of Technology, is now being tested in Vienna's bike-sharing system; another, developed at Cornell University, is already in use in New York City.

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.

Dublin Cycle Planner needs a health warning - Irish Cycle
An extensive catalogue of shitty routing. Poor...
It’s expected that any new mapping and routing systems will have errors which will need to be ironed out but the level of issues with the NTA Cycle Planner is far beyond what you’d expect in a light and quiet beta launch. It’s beyond acceptable for a public PR launch directing people to a route planner with no clear warnings. It looks like a rush job which allows junior minister Alan Kelly to get his name in another press release before the end of the year.

The Best Bike Lock
Interviews with 2 New York bike thieves (one bottom feeder, one professional), reviewing the current batch of bicycle locks. Summary: U-locks are good, when used correctly, particularly the Kryptonite New York Lock ($80). On the other hand, Dublin's recent spate of thefts are largely driven by wide availability of battery-powered angle grinders (thanks Lidl!), which, according to this article, are relatively quiet and extremely fast. :(

Street Cuffs: L.A. Sees Big Jump In Bike Thefts
Some [LA] bike messengers last month took justice into their own hands when they caught two suspected thieves, teenage boys who attended a local Catholic high school. According to police, the messengers stripped down the teens to their boxer shorts before taking their cellphones, backpacks and clothes.

“They meted out street justice. We don’t condone street justice. They never threatened them. But they made it clear: don’t mess with another person’s property,” Los Angeles Police Lt. Paul Vernon said. “This incident and the arrests are the tip of the iceberg when comes to people stealing bicycles.”

Vernon said the two boys told police they were robbed by about 20 men on bicycles at 6th Street and Grand Avenue about 3 p.m. on Jan. 12. Investigators said they cannot prove the boys were stealing bikes and continue to look for the assailants.

Limerick-Tralee walking/cycling route blocked by farmers
Oh for god's sake. I know a few people who've made a trip to Mayo explicitly because the Greenway was there to visit. This is shocking, backwards stuff:
The success of [Mayo's] Great Western Greenway [trail] has overtaken that of others, such as the Great Southern Trail group, which has been working hard to install a walking and cycling route on sections of the former Limerick-Tralee railway line.
On February 2nd, to mark the 50th anniversary of its closure, about 150 members and supporters of the Great Southern Trail set out from the old railway station at Abbeyfeale, Co Limerick, along the most recently developed section to cross the Kerry county boundary. The trailers were greeted by a barricade on the border, manned by more than 30 farmers, including the Listowel Fine Gael town councillor Denis Stack. A stand-off continued for three hours, with the Garda mediating in vain. The farmers were trying to lay claim to the land occupied by the disused railway line, even though Minister for Transport Leo Varadkar had made it clear that CIÉ “is the owner of the property [and] will object to any application by others to register these lands”.

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.
