Crossing the Double Yellow Line
If you are like most motorists, you take the first opportunity to pass the cyclist safely, regardless of the stripe. After all, the purpose of the solid yellow line is to indicate where it is unsafe to pass, and the purpose of prohibiting drivers from crossing a solid yellow line to pass another driver is to prevent unsafe passing. So if it is safe to pass, then why is the solid yellow line there in the first place?[more inside]

"Advertising is not well. Though companies supported by advertising still dominate the landscape and capture the popular imagination, cracks are beginning to show in the very financial foundations of the web. Despite the best efforts of an industry, advertising is becoming less and less effective online. The once reliable fuel that powered a generation of innovations on the web is slowly, but perceptibly beginning to falter. Consider the long-term trend: when the first banner advertisement emerged online in 1994, it reported a (now) staggering clickthrough rate of 78%. By 2011, the average Facebook advertisement clickthrough rate sat dramatically lower at 0.05%. Even if only a rough proxy, something underlies such a dramatic change in the ability for an advertisement to pique the interest of users online. What underlies this decline, and what does it mean for the Internet at large? This short [PDF] paper puts forth the argument for peak advertising—the argument that an overall slowing in online advertising will eventually force a significant (and potentially painful) shift in the structure of business online. Like the theory of Peak Oil that it references, the goal is not to look to the immediate upcoming quarter, but to think on the decade-long scale about the business models that sustain the Internet."

Verizon and Cogent Communications are at odds over how much money needs to change hands to deliver decent Netflix performance. Verizon has developed a rival to Netflix, Redbox and have been accused of tinkering with Netflix and AWS speeds due to the recent FCC Net Neutrality ruling. Things may change again, but then again, maybe not really.

Email Links Top Christie Aide to GW Bridge Scandal. The week of September 9, 2013, traffic was bad on the approach to the George Washington Bridge -- the busiest bridge in the world. Cars were backed up into the streets of Fort Lee, NJ, gridlocking the entire city on the first week of school. The reason? Two tollboths leading to the GWB were closed by the Port Authority of NY and NY. The PA claimed it was for a traffic study, except that the head of the Port Authority, Pat Foye, appointed by New York Governor Cuomo, was not told about the closure, and neither was anyone else.

San Diego Study #3: Midday Traffic Time Collapsed and Reorganized by Car Color
Lewis Lehe created an interactive graphic that shows what happens when one driver brakes in traffic
Roads kill map: an interactive map of worldwide traffic fatalities, including causes of death and levels of enforcement, created by the Pulitzer Center. According to the WHO, road injuries are the 9th cause of death worldwide, with 90% occuring in developing countries where they are expected to rise to the 5th rank, "leapfrogging past HIV/AIDS, malaria and tuberculosis", due to growing traffic numbers and lax enforcement.

You know how it feels when you're trying to cross the street and a driver comes through the intersection as if you’re not even there? Like he’s muscling through with that big box of metal as if to say, “Hey, get out of my way, you little flesh-and-blood weakling!”
Wouldn’t you just love to have a superhero sweep down, stand up to the jerk behind the wheel, and block the car so you could cross safely?

For the last several months in Mississauga, Ontario, someone has been repeatedly vandalising a roadside memorial at the Glen Erin Drive overpass. The memorial is maintained by the father of Thomas Jasinski, who died in a car crash at that location in 2009. After an extended investigation, the vandal in question has been found, and in today's Toronto Star he has stepped forward to give his side of the story. [more inside]

Traffic jams without bottlenecks—experimental evidence for the physical mechanism of the formation of a jam
The mathematical theory behind shockwave traffic jams was developed more than 20 years ago using models that show jams appearing from nowhere on roads carrying their maximum capacity of free-flowing traffic - typically triggered by a single driver slowing down. After that first vehicle brakes, the driver behind must also slow, and a shockwave jam of bunching cars appears, traveling backwards through the traffic. The theory has frequently been modeled in computer simulations, and seems to fit with observations of real traffic, but had never been recreated experimentally until recently (PDF of SCIENCE). The authors also released video of their experiments which has since been posted to YouTube. [more inside]
"Where I come from, a little patience at the crosswalk usually rewards me with a stoplight-induced pause in traffic, but here things are different. One had to simply cross, stride forward into the asphalt gauntlet with no fear, just faith that two intersecting streams of traffic, both vehicular and pedestrian, would reconcile themselves. And they always did." Photographer Rob Whitworth stitches together 10,000 images to bring you a very kinetic time-lapse video of "Traffic in Frenetic HCMC, Vietnam." [via]

The BBC has put up a page presenting statistics dealing with deaths on British roads between 1999 and 2010. A slightly older page presenting mostly the same statistics (up to 2008) can be visited here; this earlier version was published in conjunction with several other articles, including one looking in-depth at a single crash and its aftermath in Stevenage in 2007.
The Stop Sign Wasn’t Always Red. Yellow signs were used before there was a way produce a reflective material in red that would last. We have the Mississippi Valley Association of State Highway Departments to thank for the stop sign’s iconic shape. In 1923, the association developed an influential set of recommendations about street-sign shapes whose impact is still felt today. The recommendations were based on a simple, albeit not exactly intuitive, idea: the more sides a sign has, the higher the danger level it invokes. [more inside]
In the early 1960s, East German Karl Peglau came up with the idea to put hats on pedestrian crossing signal figures. To commemorate the 50th anniversary, Der Spiegel has posted pictures of two dozen crossing signals from around the world.

A short story of traffic tickets, goldfish, and love starring David Tennant and Sophie Hunter
Air traffic in much of northern Europe halted – due to ash from a volcanic eruption under the Eyjafjallajokull glacier in Iceland. The volcano under the glacier erupted for the first time in 200 years last month and whilst Iceland is renowned for its volcanic and geologic activity the sheer ferocity of the latest eruption (thought to be 20 times more powerful than the initial eruption on the 20th March) and prevailing wind conditions have culminated in the current traffic chaos. Flightradar24.com shows the current impact on the skies. Whilst the particles will disperse at high altitude and pose no threat to those on the ground, the volcanic ash is very dangerous to aircraft . Not only is there the problem of it clouding pilot vision but the ash can cause engine malfunction and damage the delicate airframe skin. One silver lining in all this is the anticipated glorious red sunset that should follow.
