At 11 points in northern Virginia, the familiar straight dashed lines on the road gives way to a series of zig zags. The unusual markings, the result of a pilot project from the Virginia Department of Transportation, are meant to alert drivers to be cautious where the Washington and Old Dominion (W&OD) Trail intersects with the road — and bicyclists and pedestrians frequently cross.

After a year-long study of this striping treatment, Virginia DOT officials say the markings are effective and should become part of the Manual on Uniform Traffic Control Devices — the playbook for American street designers.

VDOT found the zig zag markings slowed average vehicle speeds, increased motorist awareness of pedestrians and cyclists, and increased the likelihood that drivers would yield. They also noted that the effects of the design change didn’t wear off once motorists became used to the it — they still slowed down a year after installation.

VDOT says the results indicate that zig zag markings are a more cost-effective solution for conflict points between trails and high-speed roads than the current treatments: flashing beacons placed above the road or off to the side.

The zig zag concept was imported from Europe. It is currently used in only two other locations in North America: Hawaii and Ottawa, Ontario. It was one of more than a dozen European traffic management techniques VDOT zeroed in on to test locally.

Awesome 11-Year-Old Defends Road Diet, Calls Out LA’s “Bullying” Drivers

In case you need a reason to feel confident about the next generation of livable streets advocates, check out this viral video of 11-year old Matlock Grossman, standing up for a road diet in his Los Angeles neighborhood.

Grossman has been bike commuting since he was seven, and now commutes five miles each way to school. Unfortunately, like many bicycle commuters, he has already experienced his share of harassment from drivers.

At a public forum about a road diet and bike lanes implemented on Rowena Avenue, here’s what Grossman had to say to the project’s detractors:

Clearly there are motorists out there who not mature enough to share the road without having the rules painted on the road to show who goes where. The road diet by design is meant to slow down cars because – motorists are the problem.

Even if there are zero bicyclists taking advantage of the bike lanes, it doesn’t matter. The road diet effectively reduces collisions and the statistics prove this.

Stop bullying and victim-blaming the pedestrians and bicyclists as being the problem.

You Won’t Soon Forget These Photos of Ghost Bikes. That’s Exactly the Point.

All images from ##'t Forget Me## by Genea Barnes.

You’ve seen them, locked to signposts on the side of the road. Maybe you’ve helped install one. Maybe you’ve cried at the sight of them.

Ghost bikes memorialize people who have been killed while riding bikes. The bikes don’t usually stay up for more than a few weeks or months before the city removes them or they get stolen. Artist Genea Barnes has found a way to keep the memory alive a little longer.

Her photo book, “Don’t Forget Me,” is a sad and beautiful commemoration of those who have lost their lives to traffic violence. Barnes went on a road trip around the United States to find and photograph ghost bikes before they disappeared.

After Another Cyclist Dies, David Cameron Considers Truck Ban in UK Cities

Following the death of 26-year-old cyclist Ying Tao, British Prime Minister David Cameron said he would look into a truck ban for city centers throughout the UK.

In a meeting with the British equivalent of the Congressional Bike Caucus, Cameron promised to ask Transport Secretary Patrick McLoughlin to come up with recommendations for improving cycling safety in the country. He suggested that that list could include a ban on trucks in city centers, improved intersection design, and staggered traffic light phasing. Cameron also said he would ask officials to look into greater enforcement of rules mandating that trucks feature certain safety features.

More than half of London cyclist deaths involve trucks. Six of the seven cyclists killed in London so far this year were women hit by construction trucks.

Parliamentarian Ben Bradshaw, the cycling group’s leader, noted that Britain’s major cities “have a lamentable record both for levels of cycling and for cycle safety compared to those of our European neighbours, and it would take very little public investment to make a big improvement in the climate for cycling.”

The government is currently drafting a Cycling and Walking Investment Strategy. Currently, about 2 percent of trips in Britain are made by bike, but less than 1 percent of transportation funding goes to cycling.

Several European cities prohibit the entrance of heavy vehicles into downtown areas during peak hours, including Paris, Dublin, and Prague.

Earlier this year, London mandated that trucks over 3.5 tons need to have side guards to protect cyclists from being dragged under the wheels and extra mirrors to eliminate blind spots.

While the city maintains a peak-hour ban on the largest trucks (over 40,000 pounds) on specified city streets, Mayor Boris Johnson has rejected calls for more comprehensive regulations, like extending the ban to cover the type of truck involved in the killing of Ying Tao.


Harvard Researcher Calls for Better Police Reporting of Bike Crashes

Police departments need to improve the way they investigate, document, and convey information about crashes involving cyclists, according to a new study by Harvard public health researcher Anne Luskin in the Journal of Injury Prevention.

While police reports are standardized to record relatively detailed information about car collisions, the same is not true of collisions involving bikes. Better police investigations of bike collisions would help researchers, policy makers, and street designers understand what puts cyclists at risk and improve safety, according to the authors.

Lusk analyzed police crash reporting techniques in all 50 states. She also examined 3,350 police crash reports of bike collisions in New York City.

The information in the reports tended to be scarce and insufficient to determine what caused the crash. Police only consistently reported whether a cyclist was involved and whether the cyclist was wearing a helmet, her team found. Police did not consistently report factors like street conditions, angle of impact, and other information that would be useful in understanding what contributes to collisions and injuries.

Lusk recommends that police reports be modified “to include bicycle-crash-scene reporting fields.” Right now, information that is recorded about bike crashes isn’t specially coded for entry into a spreadsheet — the type of standardization that makes data widely accessible. Police forms should include information like what type of bike infrastructure, if any, exists at the crash location; whether either person involved in the crash was turning; and the points of impact on the car and the bike.

There is less room for error if crash reports are filled in not by hand but with handheld tablets, the authors note. Many state police departments are already moving in that direction.


Meet the Man on a Mission to Make Florida Walkable and Bikeable

Billy Hattaway just might have the most challenging job in any American transportation agency. As the Florida Department of Transportation’s lead official on bicycle and pedestrian safety, he’s charged with making Florida — consistently rated among the deadliest states for walking and biking — safe for people to get around under their own power.

Since FDOT hired him for the post in 2011, Hattaway has been leading the effort to reform the way this enormous agency designs and builds streets, winning accolades from advocates and the national press in the process. He also heads up one of Florida DOT’s seven districts, directing policy for the southwest corner of the state.

We recently spoke to Hattaway about how the reform process is going. Here’s what he had to say. The interview has been edited for length and clarity.

What were you doing before you were at FDOT?

I was working in the private sector. I worked for 25 years at Florida DOT in three stints. I was trying to advance these [street safety] concepts in the late 80s and early 90s and I didn’t have much success. So I went to the private sector.

I was consulting with VHB [Engineers], which is based in Boston. Most of the work that I did was bike and pedestrian planning. I was doing station area planning for the extension of the Phoenix light rail. It was all form-based code and street design basically for the Phoenix light rail.

It sounds like you have been given a very hard job.

We had to do a lot of structural changes to the organization to drive the change. We have 6,500 employees and you’re trying to change 50 years of planning and design culture.

Study: What Puts Cyclists at Greatest Risk? It’s Not What You Wear

When a cyclist is killed or seriously injured, the responses you hear often pin the blame squarely on the victim. “Why wasn’t she wearing a helmet?” Or, “Why was he wearing dark clothing? “

But according to a new study [PDF] by a team of Canadian university researchers, those factors don’t seem to have much impact on the overall severity of injury when cyclists are hurt in collisions.

The report looked at injury severity among about 700 adults in Toronto and Vancouver who were hospitalized after a bike collision or fall. Researchers teased out which factors had the biggest impact on the extent of people’s injuries.

Here’s what they found.

What DID Put Cyclists at Greater Risk? 

Being hit by car

Duh, of course! But this point is worth reiterating. The cyclists who were injured in collisions with cars, or by falling to avoid a car collision, were more severely injured than people who just fell, or were involved in a collision with another cyclist or pedestrian.

Riding on sidewalks or shared use paths

Researchers found that people who were injured while riding on sidewalks or shared-use paths tended to sustain worse injuries, even compared to cyclists riding on major roads with no bike infrastructure. These counterintuitive results suggest that riding in places with potential conflicts between cyclists and pedestrians can be more dangerous than people assume. An earlier study by the same research team found people riding on sidewalks and multi-use paths were also more likely overall to be involved in a collision or crash.

Life-Saving Truck Design Fix Sidelined By Federal Inaction

This is the second post in a Streetsblog NYC series about safety features for large vehicles. Part one examined the case for truck side guards and New York City’s attempt to require them for its fleet.

American cities are beginning to take the lead on requiring side guards on large trucks in municipal fleets. That’s a good first step toward saving lives, but without addressing privately-owned vehicles, city streets will not be safe from trucks that tend to crush people beneath the rear wheels after impact. The federal government continues to drag its feet, and without a national mandate, the prospects for meaningful action from the states look slim.

Last year, the National Transportation Safety Board recommended installing side guards on all large trucks, but the National Highway Traffic Safety Administration, which regulates truck design, has yet to pass a rule requiring them. NHTSA says it might begin soliciting input on new trailer guard rules by the middle of next year. Traditionally, the agency has focused on guards for the back end of trucks, which protect car occupants in rear-end collisions. There’s no guarantee that any progress toward new rules next year will include side guards.

In the absence of federal rules requiring side guards for trucks, New York state and local legislators have taken tentative steps toward addressing the problem. Albany’s previous attempts at similar legislation don’t inspire confidence, however. A recently enacted state law mandates “crossover” mirrors to reduce the size of blind spots in front of trucks weighing at least 26,000 pounds that operate on New York City streets. Enforcement of the mirror law is dismal, in part because of a loophole that exempts trucks registered out-of-state. The ultimate fix would be a national crossover mirror mandate, but the federal government has not shown any inclination to take that up.

Don’t Believe the Headlines: Bike Boom Has Been Fantastic for Bike Safety

safety in numbers 77-12 570

The Governors Highway Safety Association released a report Monday that, the organization claimed, showed that the ongoing surge in American biking has increased bike fatalities.

Transportation reporters around the country swung into action.

“Fatal bicycle crashes on the rise, new study shows,” said the Des Moines Register headline.

“Cycling is increasing and that may be reflected by an increase in fatal crashes,” wrote

“Bike riding, particularly among urban commuters, is up, and the trend has led to a 16 percent increase in cyclist fatalities nationwide,” reported the Washington Post.

Bike fatalities are a serious problem that needs to be tackled. The United States has dramatically higher rates of injury and death on bikes than other rich countries, and it would be appropriate for GHSA, an umbrella organization of state departments of transportation, to issue an urgent call to action to make biking safer. So it’s especially troubling that the main thrust of this report is complete baloney.

How Should Streetcars and Bikes Interact?

Streetcar service could finally begin this year in Washington, DC. Trial runs are already taking place. And the debate about how people on bikes will navigate the tracks is already raging.

Last week, the District Department of Transportation quietly proposed streetcar regulations that would ban bicycling within a streetcar guideway except to cross the street. Most immediately, that would prohibit bicycles on H Street NE, one of the city’s premier nightlife hotspots for young people, many of whom arrive on bikes — in part because the area has been underserved by transit until now. There are no fewer than seven Capital Bikeshare stations along the corridor.

But a bike ban on streetcar corridors could have far broader implications when DC builds out its full streetcar network, which DDOT dreams of building out the network to eight lines over 37 miles throughout the city.

DDOT clarified on its Facebook page that it was proposing to prohibit bikes “in the area of the concrete surrounding the rails (effectively the lane the streetcar is running in)… Not the entire street right-of-way.” That means, DDOT says, that cyclists can ride in the left lane — which would undoubtedly lead to conflicts with cars accustomed to seeing cyclists hugging the right edge. If DDOT is serious about that, perhaps they could paint sharrows to inform drivers that bikes have a right to be in the left lane.

Either way, a bike ban is not the best way to deal with what is, by all accounts, a thorny situation.

The Washington Area Bicyclist Association acknowledges that “streetcar tracks can pose a legitimate hazard to bicyclists” but insists that “banning bikes is not an acceptable solution.”

It’s a “solution” that came up earlier this year in Tucson and in 2012 in Toronto, where a cyclist died when his wheel got stuck in the tracks of a streetcar system that doesn’t even run anymore. Lots of cities have struggled to find ways to make the interaction between bicycles and streetcars less perilous.
