Cars, Bikes, Pedestrians in NYC

Overhead view of bicycles interacting with cars and pedestrians

Many made comments about the cyclists being clearly breaking more laws than the pedestrians and the drivers or that the cyclists were much more zippy when breaking laws (apparently implying greater danger). No one commented on the heavy imbalance in favor of cars over bikes as a way to get around. And the cars are certainly taking up the most space and the infrastructure is entirely intended to serve the interests of cars (although failing to do so very well).

Rush hour in the Netherlands . . . a bit different than NYC

Oh, so you can have lots of bikes and not so many cars after all. Hmm.

In the NYC video, the videographer inserted red flashing boxes, circles etc., when bikes got too close to pedestrians, cars too close to bikes, and so on - a comment was that being close isn't necessarily dangerous. And we see that in the Netherlands where the tolerance for close maneuvering on bikes blows away anything one would see here.

The GW Parkway Bike Trail Detour - Enhanced!!

Looking up - new asphalt "speed bump" covers the previous ruts

So, I had this email address for a fellow at the Park Service who is a manager for the GW Parkway and I wrote him over the weekend saying that the bike path detour seems rutted and dangerous - I got a reply today and he said he would send some fellows out to look at the situation although he wasn't sure if the Park Service had jurisdication. I wonder if this is the result . . .

Anyway, in order to solve the rut problem, which I guess someone thought was the most important, they have put in soft asphalt "speed bumps" with nice yellow stripes on them. The one on the top end is already (after less than a day) a wreck since the narrow bike tires have cut through it, creating a mess. The one at the bottom seems to be holding up better - assuming that is what one wants.

The main virtue of the previous iteration was that it was a wide detour, but that has been "corrected" with a new fence - now it is narrower. I can't imagine why they did that. Perhaps they will come back and fix it some more??

This isn't one of those "instead of making it better, they made it worse" situations but more like "instead of making it better, they made it different - and still bad."

Poor Bike Trail Detour, GW Parkway

I took some pictures of this yesterday and Washcycle has a blog entry using them.


New "cut through" detour near south end of 14th St Bridge

The photo doesn't convey the difficulty of riding this particularly well - the construction people followed the natural contour of the hill so the lower section is shallow and then it quickly gets pretty steep for most cyclists. When riding up this, about one in four cyclists gave up part way through and dismounted. Even though it is quite wide, many riders have difficulty focusing on both the difficult surface straight down and other riders and pedestrians.

In the photo above, the old-timer recumbent rider was able to pedal straight up the incline; the other fellow ahead of him slowed down and stood up to make his way to the top. Of course, when he stood up to pedal he immediately slowed down and the recumbent is practically running into him.


Loose gravel at bottom - similar ruts are at top

In addition to being steep, there are these ruts to navigate successfully.

My thought is that if they do nothing else, there should be "walk your bike" signs (much as I don't like those). I contacted the Park Service management for the GW Parkway here to suggest there was a problem at this location that needs correction or people may well get hurt. No reply so far.

Idaho Rolling Stop Law Video

Excellent video about the Idaho "Rolling Stop" law for cyclists for use in Oregon as an advocacy tool.

Bicycles, Rolling Stops, and the Idaho Stop from Spencer Boomhower on Vimeo.

Makes it clear how the law operates in Idaho and what is allowed - and prohibited. Also, points out that this law increased the fines for violations.

Self Defense for the Cyclist (1901 article)

Self-Protection on a Cycle is an article in a 1901 issue of Pearson's Magazine, a British magazine. I found reference to it (albeit a bit obscure) in a Russian web site (where some of the illustrations have been posted).



The article covers the following~

How you may Best Defend Yourself when Attacked by Modern Highwaymen, Showing how you should Act when Menaced by Foot-pads, when Chased by another Cyclist, and when Attacked under various other Circumstances ; Showing, also, how the Cycle may be used as a Weapon.

explaining that

Self-protection awheel is an art full of possibilities. The cyclist who is a skilful rider, who possesses pluck and dash, who has mastered the elementary rules of defence on a bicycle, and who is armed with a knowledge of how to use a machine to the best advantage as a weapon, may rest content that he is able to defend himself perfectly when attacked under the majority of likely conditions.

The article then goes into considerable detail, with photographs of the "tactics," on how to achieve the best defensive results.

Rocket Scientists Think Cycling is Safe (Enough)

NASA pulls injured shuttle astronaut off flight (Associated Press item)

An astronaut who crashed his bicycle last weekend won't be taking part in space shuttle Discovery's final voyage next month.

. . . . .

To cut down on preflight injuries, NASA has a whole list of prohibited activities for astronauts assigned to space missions. Among the banned high-risk sports: motorcycle riding, skiing, parachuting and acrobatic flying. Bicycling is not on the list.

Winter Commuting & Studded Bike Tires (Again)

So, Tuesday night it snowed again, setting up a slick commute (so to speak) for Wednesday morning, and a bit beyond as it turned out. In an earlier post I said I didn't see much point in studded bike tires, but I realize now I was thinking mostly of heavy snow conditions like we had last winter (where the problem was pushing through snow and not ice at all).

Tuesday's freezing rain followed by an inch or so of snow set up conditions where bike tires with studs are pretty good to have - and since I have a set, I used them (although I took the picture above of some other rider during my commute - the pictures below are of me + the bike).



This is an old Giant that belonged to one of my sons - I have an extra set of wheels that I equipped with some not-very-expensive Nashbar-branded Kenda tires that have studs. They work great in icy conditions. In the image below you can see, if you look closely, some of the studs.



It got up to 38 (F - say +2 C) during the day and it was windy, so much of the snow melted by the time I rode home, but there were enough icy patches that I didn't mind having the studs. Really, it is on icy spots (rather than on snow of any depth) that the studs are amazing - it is possible to proceed at a decent stable pace, say 12-14 mph, and not feel any slipping, although one needs to be sensible - the studs aren't so numerous as to be relied on for quick stops, for example. When traveling on dry clear pavement one can hear them clicking away and I assume getting slowly less pointy (flattened out). If you brake hard on dry pavement you can simply pull individual studs out of the tires.

So Thursday, having decided that mostly the trail was clear, I went back to my cyclocross bike (no studs). I reduced the tire pressure to 50 pounds per square inch but that does zero for grip on ice. Using the cross bike meant lots of speeding up, then slowing down when I had to go over icy areas plus making sure I was paying attention 100 percent of the time so as not to end up on ice at the wrong speed. On the way home on a overpass made of concrete (which thaws much more slowly since the jurisdictions where the bike trails are don't do anything to speed that up), I screwed up and fell, dinging my left shoulder pretty good but not breaking anything. My head hit the left concrete sidewall of the overpass but not too hard and anyway that's what helmets are for, to keep one from getting hurt (and it worked). Nonetheless, OW!

So I'm a little embarrassed, frankly. I could have and I guess should have ridden the "ice bike" with studs one more day in order to avoid this. It would have been 9.5 miles of studs and heavy mountain bike on clear pavement and some 100s of yards on snow and a little slippery, dangerous ice. And I'm pretty sure I would not have fallen ~ hmm. Have to think about this . . .



I should have spent one more day on the studded tire bike.

Rider in Accident Near Park Tool School Dies

In a previous post I wrote about driving to a session of the Park Took School in Alexandria (VA) and observing where a car-bike accident had clearly taken place in the previous half hour or so - a beautiful randoneering bike was laying in the middle of the intersection with police everywhere. I now read that unfortunately he has died from his injuries.

The article notes that, According to FABB, this type of crash is very common for accidents involving vehicles and bicycles. Drivers making left turns at green light yields often do not see approaching riders or misjudge the bike's speed.

At age 16, I hit a car making a left turn in front of me on Connecticut Avenue in DC and rolled over the car, ending up sitting on the asphalt of the other side of the car wondering where my bike had gone (the bike stayed on the side where I hit the car - I had a concussion). Didn't ride again for years.

Certainly sad to read that this cyclist passed away.

Inflatable Helmet? Swedish Nuttiness

Article in Huffington Post points to Reuters item about a Swedish-developed "inflatable helmet" that activates in the event of fall or accident - but at $450 each this seems unlikely to serve as a popular alternative for adults who choose to avoid traditional helmets, which is the intent.

I also learned that Huffington Post has a (minor) category for "bike culture." Good!
