Dimensions of Speed Humps

Of course there are several different types of vertical deflection, with variable effectiveness. The most effective are taller and steeper. The least effective types are most in vogue for reasons you can probably guess. Sorry I don’t have the source for this in front of me.

P.S. One speed hump costs about 2K$, roughly 1/8 the cost of a mini roundabout. By all indications they are far more effective traffic calmers than are mini roundabouts.

Chrysler has been Rolling Coal on America

A company that failed a few times and exists today only because of taxpayer billions, now owned by Fiat and making most of its products in Mexico, further expresses its gratitude by filling American air with as much poison as it possibly can.

In 2015 and 2016, the company sold more than 50,000 diesel Ram 1500 pickups a year in the United States, making it by far the largest-selling diesel-powered light vehicle in the country.

Each one of them equipped with emissions-cheating software.

Hey Denver People Are Your Lungs Burning?

At least two major blasts of SO2 into Denver’s air by the Suncor refinery within the past 6 months, caused by power outages at the plant. Two that were disclosed that exceeded local and federal standards. SO2 hurts lungs and it ruins plants and trees.

What are the health effects of SO2?

Short-term exposures to SO2 can harm the human respiratory system and make breathing difficult. Children, the elderly, and those who suffer from asthma are particularly sensitive to effects of SO2.SO2 emissions that lead to high concentrations of SO2 in the air generally also lead to the formation of other sulfur oxides (SOx). SOx can react with other compounds in the atmosphere to form small particles. These particles contribute to particulate matter (PM) pollution: particles may penetrate deeply into sensitive parts of the lungs and cause additional health problems.

Colorado State Senator Andy Kerr Proposes “Idaho Stop” Law, Local Bike Guy Freaks Out

http://www.denverpost.com/2017/01/26/senate-bill-bicyclists-stop-signs/

Idaho Stop is something I’ve been promoting for many years—in Denver, a place where most riders already practice the technique, it makes even more sense than it does in Idaho—but to say my pleas fell on deaf ears is a bit of an understatement. The advocacy orgs like Bicycle Colorado and BikeDenver were big on the law-and-order stuff.

To hear the local advocacy groups now getting behind Kerr’s bill is extremely heartening. Extremely surprising and somewhat weird. But I’ll take it.

Idaho Stop. There is no fact-based opposition to it. It is proven to work, with decades of data. It makes life better for bicyclists, and so makes life better for all. But that doesn’t mean this will become law. Most people are still idiots about bikes, and even a substantial portion of cyclists are reflexively opposed to the idea, although that portion is clearly getting smaller and smaller all the time. If you’re still in that portion, get on out of it and into the other one.

Udate: SF Pulled Registration of Uber’s Driverless Douchemobiles

Even before I wrote yesterday’s post, Uber, refusing to apply for permits to run driverless cars in the city, had their vehicles officially booted from the Streets of San Francisco. Uber sent them by truck to Arizona, where a coalition of douchebags was waiting to greet them warmly, based on the company’s disdain for permits alone.

Uber Launches Driverless Cars In San Francisco, Problems Evident

Uber says it’s a matter of principle to run these autonomous vehicles in the city before they’re ready to run safely. Really did say that. SF Bicycle Coalition is on their case as the vehicles are observed flailing around bike lanes and running red lights. Is SFBC an ant standing in the way of an elephant? Wait, not an elephant. Elephants are very cool. An ant standing in the way of a steamroller? A DRIVERLESS STEAMROLLER?

NYPD has a strange response to the murder of a bicyclist

RIP Matt Von Ohlen

Police are currently looking for the driver of the black Camaro who knocked Von Ohlen off his bike then ran over him, then sped away. If they find him/her, may give him/her a bike safety pamphlet.



RIP Virginia Murray, First bike-sharing fatality

Tragic and horrible.

Thompson Rivara Thompson ’96

Thompson, Rivara and Thompson M.D.s, “Effectiveness of Bicycle Safety Helmets in Preventing Head Injuries,” JAMA, 1996.

RT96tablew

This is probably the most cited of all helmet studies. It appeared at a time when the CPSC was considering the possibility of making new standards for little kids’ helmets. On one side of the discussion, engineers and advocates who thought child and toddler helmets should be made softer to protects kids from the type of head injuries they are most likely to suffer while bicycling. On the other side, helmet company reps who argued that kids didn’t need new standards or softer helmets.

Thompson, Rivara and Thompson’s “Effectiveness of Bicycle Safety Helmets in Preventing Head Injuries” came along just in time to lend the industry some apparent scientific legitimacy to their argument.

The study concludes like this: “Based on our study, changes in helmet certification standards or the design of helmets particularly for younger age groups are less likely to result in major benefit.” The mention of kids’ helmet standards–“particularly for younger age groups…”–comes out of the blue at the end of the paper.

This is quite strange because, earlier in the document, the authors revealed that the study, which included over 3,000 crashed cyclists, included only one helmeted brain-injured subject under 6 years of age. Because of this almost total lack of data, the authors admit that their study cannot estimate any protective effect of helmets for this age group.

Hmm. But in the conclusion, which is the only part of the privately held document that journalists or 99% of the public will ever read, the authors do just that. They claim that helmets give the same protective benefit “to cyclists of all ages…” And then they go out of their way to say that bit about little kids not needing better helmet standards.

I don’t know about you, but I think it’s very interesting that the particular age group that receives the most attention in the conclusion, is the one that received the least attention when collecting data. This seems to be a really smarmy piece of work.
