Bicycling
Make your own laser bike lane
Tired of cars passing you too closely while bicycling at night? Some designers have created a system to project your own bicycle lane on the street behind you, using lasers. Tip: Martin.
From the picture (left above), these lines don't seem to be three feet from the cyclist, however. The law in DC (as of December) and in many other places requires three feet. What about combining this laser idea with Joe Mizerek's "3 Feet Please" bike jerseys, and projecting lines three feet to either side of the cyclist, with the words "3 feet please"? Then motorists can be sure of the safe distance to pass.

Second the law itself states that "...shall exercise due care by leaving a safe distance between the motor vehicle and the bicycle of not less than three feet" - It never mentioned a point on the bicycle to be measured. Is is the wheel? the outside of the handlebar? The cyclists shoulder?
Third, the district's burden of proof for a moving violation is "clear and convincing evidence." I would imagine that any ticket given would be open to easy challenge, due to both the ambiguity of the law, and the fact that it is clearly hard to eyeball 3 feet.
I think conceptually this is a good idea, but the law seems to be thrown together in such a haphazard way that would make it practically unenforceable. Unless of course I am totally missing something here...

I suggested that people should wear helmets irrespective of the number of cars on the street. Many crashes result from causes other than automobiles and the rider doesn't need to be going at a high rate of speed to cause serious damage. Are there any suggestions to have bike-sharing programs require helmet usage?

I just wish there was as much attention paid to pedestrians and the pedestrian experience, slow and easy as it often is, on this blog as to the cyclists. There are more of us/them than cyclists. Back when I last complained about this, there was a response like just wait, we're about to do something on sidewalks. And sure enough, there was, but in the photo was, of course, bicycles! And as memory serves, the discussion was bicycle-centric. Aargh. Maybe it's because most of the people on this site are below 30 or 35? I have no idea.

People on this site are envious of Beijing circa 1979 due to the fact everyone biked.

I'm happy to write about pedestrians. I'm a very strong advocate for pedestrian safety. I see almost everything we write about, like walkable development, contributing in some way to pedestrians. Every time I write about a curb cut the biggest argument against is pedestrians.
I mainly get article ideas from the news, from government hearings and meetings (like legislation before local governments, community sessions, etc.) and from tips sent in by readers. When the DC Council was debating the fine for not yielding to pedestrians, or Montgomery County doing its poor Road Code, I covered that. I asked ANC Commissioners about pedestrian safety before the election. Lately, though, there hasn't been much specifically about pedestrians, except for the general pedestrian issues surrounding development.
Do you have any specific suggestions for things that aren't getting covered? Please feel free to send in tips about articles on pedestrians. If you have ideas for a "Pedestrian Safety Enhancement Act" DC should consider, or other specific thoughts, please feel free to send me a proposed article.
I'm not avoiding covering pedestrians. It's just that I cover what's around, and there's not a lot of news about pedestrians, excecpt, again, the development impacts on them.

Also, many of the pedestrian issues are more subtle than the bicycle issues. In general, advocating for human scale walkable mixed-use street grid communities is advocating for better pedestrian conditions.
With pedestrian laws, there are currently fewer shades of gray that can be immediately tweaked. Hence, the discussion of bicycle-specific topics. The pedestrian topics are part and parcel of the larger isses of the whole built environment.

I don't think there's a legal mechanism for SmartBike to require helmet usage. I know they discussed it, but there wasn't a way for them to require it.

But since you brought it up: Lower the speed limit from 30 mph to 25 on CT Ave NW north of Calvert; Add a mid-block ped crossing with a button to call a signal on CT Ave between Newark and Ordway NW; install a speed hump on Devonshire NW just east of the northward turn; extend all crosswalk times so slower moving peds can get all the way across before the lights change; put in more of those all-stop ped crossing signals like the one installed and removed up there on CT Ave; add several questions to the driving liscense exam that specifically address ped safety; build the hiking and biking trail in Klingle Valley; reopen the only ped entrance to RCP from Columbia Heights (a locked gate across a trail head at 16th and Arkansas); create more ped entrances to RCP.

I have heard that some cities (specifically, I believe, Budapest, Hungry) place the bike path between parked cars and the curb/sidewalk. Not only are few passenger-side doors opened but also, if there was a collision, the biker would tumble in front of a stroller instead of a car. Is anyone aware of any cities that have implemented this road allocation policy in the US?

I can see how Cavan would believe what he wrote, but I don’t. I could go into a long rambling piece about an overfocus on development here, but I won’t. Basically for me, it’s a question of emphasis, and cycling gets tons more in this blog, explicitly so, than pedestrianism.
So, since you asked:
The long wait times at traffic lights – what’s happened in the last few years? People used to be able to push a button and the light would change in a reasonable amount of time. Now nothing. Those little contraptions still might be on a lamp post, but as far as I can tell, they don’t work.
For all the talk about penalizing drivers for veering over two millimeters into the bike lane, what about drivers not yielding to pedestrians in the zebra walks? Or did I miss that?
Toy with the idea of pedestrian supremacy for a day. Just play with it.
I don’t mean to start an aggressive conflict between two opposing sides who amp up the disagreement with every exchange, and attempt to find an endrun at every opportunity, but …a bicyclist on the sidewalk is NOT a pedestrian’s best friend.
Think what and who your allies are if you are a pedestrian: BUSES. Thousands of topics just with the buses. But there’s not enough money, glamour, etc there for numerous postings, I guess.
I haven’t seen many if any entries on being disabled in this city.
Though speeding no doubt is a problem some places, I just don’t get that annoyed by it a lot (from time to time yes), though yes yes, it’s dangerous. What bothers me much more so than speeding (DC is a town with pretty slow drivers, is my overall impression, which is a good thing, I guess) is aggressive driving, a car swooping behind you within a foot or two. That should be illegal! Hey! Kind of like this blog entry, but for pedestrians.
There was something in this blog about a pedestrian who was hit in Chinatown recently. But just a day or two or three before that, or around the same time, a pedestrian was KILLED in NW, but there was nothing on this blog about it.
But by far, the biggest one is the closing of public sidewalks due to construction. It’s illegal and should always be stopped.
Lots lots more, but that was just kind of off the top of my head.

1. The efficacy of helmets is at least somewhat in doubt.
2. A helmet only protects the user and only once the collision or fall has happened. People should have the right to take risk - even stupid risk.
There is greater consensus around sunscreen, than bike helmets and the use of it by everyone would have a much larger positive impact on health than 100% helmet use, but would you really support a law for it? What about dental floss? Safety goggles? Gloves? Where do you draw the line?
For SmartBike, requiring helmet use - without providing helmets - would really cut back on use. People have the right to be stupid.

Bike-sharing programs should provide helmets with the rental of a bicycle. Helmets are not a major expense in the overall cost of a bike-sharing program and would greatly enhance safety when riding in an urban environment.
by Ben on Jan 12, 2009 10:38 pm
But if your intention is to kill bike sharing, press on.

How about back in angle parking on one side, one through lane in each direction, designated left hand turn lanes and signals, timed lights (similar to Connecticut ave by Chevy Chase circle) and a bike lane in each direction. Wave the magic wand and make this section of DC roads greater!

They tried a protected bike lane in NYC, along with a ton of bikelanes they have added there recently. It is better.
Bikelanes are a death trap though. I advocate for driver/biker education and bikers being offered their place in a lane. It is in the DC traffic code that a bike can occupy any part of any lane. The idea is to be courteous and not slow traffic.
Bikelanes have the understood benefit of encouraging people to ride; more people riding encourages sharing of the road. I never feel safe in bikelanes. They trap you into dangerous situations, and when they end they leave inexperienced city riders with a choice between the sidewalk (pedestrian collisions) and uncertain auto behavior. Proper education can teach riders to establish themselves in the lane and be aware of vehicle behavior (watching mirrors, making yourself seen, signals, and learning the way people drive) while proper driver education can teach drivers to look for bikes, and be aware that they may split lanes or be on either side of the car.

A seat belt is different from a helmet. Because a seat belt keeps a drier in front of the steering wheel, studies have shown that it gives the driver a greater chance of regaining control of the car once the collision has occurred and reducing the seriousness of it. Furthermore it keeps others in the car from becoming deadly projectiles that could kill other passengers or hit the driver and cause them to further lose control of the car. So that is different. Plus the efficacy of seat belts is not in question.
As for insurance and medicare, that is a slippery slope. Once you decide that you can tell people how to behave because you're on the same insurance program, well then, so can they tell you. They could tell you to eat less red meat, to not drink (or to drink exactly 6oz of red wine a day), not to work in certain places etc...They could make you wear a NASCAR style crash helmet and jumpsuit when you drive - which is quite analogous, since bike helmets were originally only used by racers.
I would recommend that someone who rides a SmartBike wear a helmet, but I'm not going to force them to.
And as far as providing helmets. Do you really want to wear a helmet some stranger just sweated into for 25 minutes? Who's going to clean those between rides? I look forward to the rampant city-wide outbreak of lice.

Since the SmartBike operates on the basis of a yearly membership, one very easy way to encourage helmet usage is to give members a discount on the purchase of a helmet at local bike stores.
One of the presenters at the TRB session said that one significant challenge for bike-sharing programs is liability issues and the difficulty of municipalities getting insurance coverage for these programs. This has led to many of these programs being funded and managed by private companies instead, such as J D Decaux in Paris or Clear Channel here in DC. If these program operators could get lower insurance rates through the encouragement of helmet usage, they will have a reason to provide users with an incentive for the use of helmets.
by Ben on Jan 13, 2009 10:58 am
The city dealt with closing sidewalks for construction a year ago or so. Now it's not allowed for new projects. Topics like that can come up again if there's something new to write about. Like I said, please feel free to submit specific tips or even articles. The bike blogosphere is pretty active, which is why a lot of bike stories come up. It'd be great to have more pedestrian blogging. I can't do it all by myself. Please help light a candle instead of cursing the darkness and send in some specifics for articles when you find them.

The separated bike lanes are not always safer than regular bike lanes. They require separate infrastructure at intersections and the maintenance needs are different. Here's a great chart on when separated bike lanes are the best option - usually roads with high numbers of automobiles moving at fast speeds. http://www.streetsblog.org/wp-content/uploads/2006/11a/bike_lane_chart.jpg

Whereas it is obvious that a physical separation makes things safer, it has amazed me how much coloring a bike lane helps. It really creates a psychological barrier for car drivers. It is my strong recommendation to any authority creating a bike lane to color the asphalt.

I pretty much gave up cycling once I left my 20s. After a while I got burned out on the close calls and getting worked up about all the shitty drivers trying to kill me. Some days I'd get to the office ready to punch somebody. That's no way to live.
So I was on the fence about this until I came across David Hembrow's blog. Here he is on the idea of subjective safety (and more).
John Pucher on Cycling for Everyone is also really persuasive.
If we're serious about climate change, obesity, mobility, social justice, and plain old quality of life, we'll stop debating how much defense cyclists need against cars (helmets, lasers, weird clothes, etc) and get real about building bike infrastructure.
