No bike racks? Just park it in the car lane

It's a frequent sight around the city. Drivers who are ignorant or who just don't care park in the bike lane when they can't find a parking space. It's rude and inconsiderate, of course, but it's also dangerous for the cyclists who have to dart into traffic to pass. How would drivers react if cyclists started parking in their lane?

The poster above was produced by Canadian design and cities-focused magazine Spacing. The image is designed to be a little provocative and to make drivers think about how they'd like it. I suspect most of them wouldn't like it one bit.

I've always wondered why people think it's acceptable to park in the bike lane. Recently I was riding on the M Street cycletrack and as I approached one of the mixing zones, a UPS driver was backing his truck into the buffered part of the bike lane. At this point, it was already after the evening rush hour, and there were 4 lanes for cars, but only one for bikes. If the UPS delivery guy had parked in one of the car lanes, he'd be blocking 1 of 4 lanes. But by blocking the bike lane, he was blocking the only bike lane.

Why is it that drivers who would never for a moment consider blocking a car lane "just for a minute," while they run inside will, without even the briefest of thoughts, park in the bike lane?

Well maybe this image can be successful in making drivers give it a little thought.

Why build protected bike lanes, in one happy quote

A father and son comfortably bike down a slow Arlington street. They approach the new Hayes Street cycletrack. The father asks "Want to take the special bike lane?" The son responds with an excited "Yeah!"

I overheard that interaction this past weekend, and had to stop and smile.

That one brief conversation sums up why protected bike lanes are so great: They make city streets safe, comfortable, and fun for even children to bicycle on. Not to mention older people, less-able people, and novice cyclists.

If Americans ever hope to make cycling for transportation a mainstream activity, cycling must feel comfortable for everyone. Getting bikes out of the path of speeding cars is a big part of that.

Protected bike lanes could fit in DC's traffic circles; here's how

London is adding protected bike lanes to one of its traffic circles. Could the same design work in DC? Would we want it to?

London city workers recently began rebuilding the Queen's Circus traffic circle to include protected bike lanes. Since central DC has so many traffic circles, it's worth considering whether the Queen's Circus design could work here too.

DC's big traffic circles are notoriously difficult places to bike. They have multiple lanes of intimidating and zig-zagging car traffic, and sidewalks too packed with pedestrians to be good bike paths. Most of the circles lack bike lanes, and those that have them (Columbus Circle and Thomas Circle) are still far from comfortable places to bike.

But the traffic circles are key destinations. People want to use them. Making the circles more bike friendly would be great for DC.

Would we want to do this?

This is sort of a good design. It's better than nothing. But with so many crossings, it's still pretty confusing what's the bike lane and what's for cars. It seems likely there will still be a lot of intimidating cross traffic.

In fact, the actual design doesn't even have the green paint; I added that to make the rendering clearer.

The other big problem with the London example is that pedestrians are mostly absent. Unlike DC's circles that typically have popular parks in the middle, this London circle is just a road. The central grassy section isn't a useful park, and there are no pedestrian crossings into it. That obviously changes how the entire thing functions.

Look to the Dutch

Perhaps a better example might come from this traffic circle in Rotterdam, where in typically Dutch fashion the bike lanes are much more well protected.

Rather than fight with cars, the Dutch put the bike lanes up on the sidewalk. That's more ideal from a cyclist perspective, but it's also much harder to accomplish.

The sidewalks around DC's downtown circles are too narrow in many places to accommodate bike lanes. DDOT could theoretically rebuild the circles to have wider sidewalks and narrower roadways, but that would be controversial to say the least, not to mention a lot more expensive than striping a bike lane on the street.

The Dutch example is better, but the British example is more achievable.

A cycletrack appears in Pentagon City

Arlington's first significant protected bike lane quietly popped up last week in Pentagon City. It runs on South Hayes Street from 15th Street to Fern Street, next to Virginia Highlands Park.

There are actually two cycletracks. There's a grassy median in the middle of Hayes Street, so in order to serve bicyclists going both directions, each side of the street has its own one-way cycletrack next to the curb.

The cycletrack connects to the new green-painted bike lanes on Hayes Street further north, forming a spine for cycling through Pentagon City.

Technically speaking this is Arlington's second cycletrack. The first one, in Rosslyn, is so short that it hardly counts. Hayes Street is the first significant one.

It's great to see such high quality bike infrastructure appearing in more jurisdictions. Who will be next? Maybe Montgomery County?

Why is Tysons walkability and bikeability so bad?

Virginia officials have known for years that Metro was coming to Tysons. Yet when the four stations opened, commuters found dreadful and dangerous walking and biking conditions. Why?

The Fairfax County DOT has been making some progress. There are two crosswalks at the intersection of Route 123 and Tysons Boulevard, which FCDOT recently installed. But at the opposite corner, there are no crosswalks. This is where Ken Archer described pedestrians running across nine lanes of traffic without any crosswalk.

According to FCDOT director Tom Besiadny, the Virginia Department of Transportation (VDOT) will not allow a crosswalk across what is now a double right turn lane. FCDOT has been discussing shrinking it to only a single lane, but that requires negotiating with VDOT, which takes a general stance of suspicion if not outright opposition to any change which slows cars.

(Update: Martin Di Caro reports that VDOT has specifically refused to let Fairfax shrink the double right lane until it conducts a six-month study about the traffic impact of the change.)

In a press release, the Coalition for Smarter Growth said these "show the challenges of retrofitting auto-dominated suburbs." It goes beyond just adding a crosswalk; even if FCDOT had one at every corner, there are still curving "slip lanes" for cars to take the turns at high speed. A more urban design would have just a basic square intersection, and with fewer lanes.

Fairfax plans a more comprehensive grid of streets to take some of the traffic volume off of the existing streets, but it will always be a struggle to make intersections smaller or slower versus continuing to design them for maximum car throughput. Even now, VDOT is continuing to widen part of Route 123 further.

According to Navid Roshan of The Tysons Corner blog, VDOT also refused a request to lower the 45 mile per hour speed limit on Westpark Drive in a residential neighborhood.

It's not just VDOT, however. Bruce Wright, the chairman of Fairfax Advocates for Better Bicycling, pointed out in a comment that many fixes for cyclists were in the Tysons Bicycle Master Plan created in 2011, but which Fairfax County has still not adopted. The plan will go to the county planning commission in October and then the Board of Supervisors.

The original plan called for a first phase of improvements by 2013, most of which are still not done. Those projects were all small, short-term items like adding sharrows and signed bicycle routes, adding enough bike racks at Silver Line stations (which are already almost out of space), and setting up Transportation Demand Management programs with nearby employers.

Roshan created a petition to ask Fairfax and the state of Virginia to prioritize fixing these problems. He points out that all of the improvements together cost less than some of the studies Virginia is doing around adding new ramps to and from the Toll Roadto move cars faster.

They shouldn't ignore traffic, but if Tysons is going to become an urban place, that means building roads that work for all users instead of maybe squeezing in a poor accommodation for pedestrians and/or cyclists as long as it doesn't get in the way of car flow.

The Fairfax County Planning Commission's Tysons Committee will meet tonight from 7-9:30 at the county's (not very transit-accessible) Government Center, 12000 Government Center Drive, Fairfax. The committee will discuss amendments to the Tysons Comprehensive Plan.

As Wright said, the county has been pushing developers to include better bicycle and pedestrian accommodations as they develop or redevelop parcels, but people riding the Silver Line now can't wait for development years down the road. Fairfax and VDOT missed chances to make the roads walkable and bikeable before the Silver Line opened, so there is no time to waste to fix these problems urgently.

See 32 years of DC bike lane growth in one animation

DC has had a smattering of bike lanes since at least 1980, but the network only started to grow seriously starting in about 2002. This animation shows the growth of DC's bike lane network, from 1980 through to 2012.


Animation from Betsy Emmons on MapStory.

From 1980 to 2001, literally nothing changed. Then in 2001, two short new bike lanes popped up. The next year there were 5 new ones. From then on, District workers added several new bike lanes each year, making a boom that's still going on.

This animation ends in 2012, so it doesn't include recent additions like the M Street cycletrack. But it's still a fascinating look at how quickly things can change once officials decide to embrace an idea.

In a few years, a map showing the rise of protected bike lanes might start to look similar. That map would start in 2009 with DDOT's installation of the original 15th Street cycletrack. It would expand slowly through this decade, then maybe (hopefully), it would boom as moveDC's 70 mile cycletrack network becomes a reality.
