If urban infrastructure had fashion trends, bike lanes today would be the leg warmers of the '80s. Leg warmers began as a simple functional piece of attire (they were originally used by dancers to keep their calves warm to prevent cramping) and became a necessary part of every teenage girl's ensamble.
In the past 10 years I have seen bike lanes installed in every condition, from the cycle tracks along Pennsylvania Avenue to converted shoulders on rural roads in Delaware. George Mason recently installed them along Patriot Circle and they have been used as part of a “road diet” in Reston.
Fairfax City has yet to hop on this bandwagon, but it has been discussed. So, should we? And if so, where do bike lanes make sense?
First, it is important to understand why bike lanes have been all the rage over the past few years. I mean, why not just use sidewalks or paths? Well, bike lanes function more like bike highways for commuters in that they don’t require you to slow down at every street crossing as you do when using a sidewalk or parallel path. It is important for bike commuters to be able to maintain a constant high rate of speed in order to make biking a more competitive alternative to driving (bikers should still stop at traffic lights and stop signs, though I realize many do not). Bike paths on the other hand are more desirable for leisure riders.
With this in mind, Main Street and Fairfax Boulevard both seem like corridors that could attract a lot of bicyclists. They are so jammed during rush hour that riding a bike can actually be quicker than driving depending on how far you are going.
There is currently no safe way for bikes to travel quickly on these routes and they often mix with traffic. Unfortunately, most of the street rights-of-way for main roads in the city are fully utilized with travel lanes, turn lanes and sidewalks. It would take a significant investment to add bike lanes to streets such as Main Street and Fairfax Boulevard because it would require moving curbs and adjusting medians.
Another potential corridor is Old Lee Highway. Although it doesn’t have the traffic congestion as the other two roads mentioned, it connects several potential bike trip generators, including George Mason University (via George Mason Boulevard), Old Town Fairfax, Fairfax High School, and the Vienna Metro. Not to mention that parking isn’t free at George Mason or the metro, which makes alternative transportation modes more attractive. A recent report from WMATA showed that the Vienna Station had the 10th highest number of bike commuters among all Metrorail stations.
Many communities also use bike lanes not just as a transportation mode, but as a traffic calming measure that takes advantage of unused right-of-way or under-utilized traffic lanes. In Arlington, several underutilized four lane roads have been converted to two-lane roads with on-street parking and bike lanes.
Two years ago, Lawyers Road in Reston was re-striped to remove two travel lanes and add a center turn lane along with bike lanes. This reconfiguration is expected to reduce vehicle accidents and “improve safety and enhance mobility for bicyclists and motorists." This is known as a “road diet” where increased capacity is replaced with improved functionality.
Some parts of Old Lee Highway have a dedicated right-of-way and even paving for additional lanes, a goal that has long since been abandoned. This makes it a good candidate for this type of reconfiguration. Bike lanes would encourage vehicles to slow down and create a buffer between traffic and sidewalks.
Even though the use of bike lanes has gone beyond their original intended purpose, they still provide the benefit of traffic calming if designed correctly and used in the right corridor.
What do you think about bike lanes? Are they useful, or just a trend? Where would you want to see them in Fairfax City?

The center turn lane configuration on Lawyers in more commonly known as a "suicide lane. So named for the number of fatal collisions arising from the use of the lane by some to pass slower traffic in the only remaning travel lane. Many states are eliminating "suicide lanes" for obvious reasons.
How is it equitable to take a lane away from other travelers on a busy road to dedicate 25% of the pavement to the >1% of travelers who ride bicycles?
That's a terrible misappropriation of a public resource.
No one would advocate giving 25% of the classrooms to 1% of the students.

I've heard that term before and I tend to agree with it in certain situations. We have a "suicide lane" along Fairfax Boulevard between 123 and Kamp Washington. But on Lawyers Road, the previous configuration had two lanes in each direction with no room for turn lanes. There were a high number of rear end collisions because people were driving too fast when suddenly someone stopped in front of them trying to make a left turn. I agree the center turn lane isn't the best configuration, left turn lanes would be more appropriate, but it is better than the previous configuration.
As on many other projects, the bike lanes were then added simply to make use of the extra paving. With the center turn lane added, there wasn't room for the two additional travel lanes. So rather than waste that space, why not make it usable for somebody, even if they are <1%?

There were only 6 rear end collisions on the 4 lane section of Lawyers in the 24 months prior to installation of the suicide lane. That's not a "high number."
The last report I saw had 4 accidents since the suicide lanes went in a year ago. Hardly a difference that would justify the loss of capacity.
There was a parallel route for the bike lane on a set of roads immediately south of Lawyers which have much lower volume and slower speeds than present day Lawyers. The bike lane should have gone there.

In Fairfax City a lot of trips are 5 miles or less -- especially non-commute trips. Just converting 5-10 percent of those trips from car to bicycling would improve traffic. There is a lot of potential to draw more GMU students to downtown businesses, and bike lanes on University Drive would facilitate this. (By the way, Fairfax City did recently stripe shared-use bike lanes on George Mason Boulevard near GMU.) So for these reasons and others I agree that bike lanes would be beneficial -- not just for bicyclists but for everyone -- and particularly in those very bottlenecked business corridors of Old Town and Fairfax Boulevard that you mention.
The benefits of road diets for motorist safety have been amply demonstrated in FHWA and other studies. They lead to fewer auto collisions. They also improve traffic flow.

John brings up the subject of lane utilization in relation to the discussion of road diets in his comment. Given that Paul does not suggest the use of a road diet on Old Lee Highway, its really a moot point. Despite this fact, it is important to note that Paul should have used the phrase "excess capacity" instead of "increased capacity." The Reston road diet was the perfect opportunity to prove just how valuable of a tool road diets really are in a county that has previously over-built roads and not accommodated all users on the roadway. This fundamental change in policy was initiated in 2006 with the creation of the County's bicycle program. Let's hope the County residents will come around to this beneficial project and can see the wisdom in this decision and that the City of Fairfax will follow suit in the encouragement of alternative modes of transportation with the construction of bike lanes in smart, logical locatioins such as Old Lee Highway.

A principal source of the Washington areas 2nd worst in the nation traffic congestion was the removal over the last 50 years of thousands of lane miles of roads.
Yes, the County has required the proffered construction of hundreds of miles of excess capacity but before its declared surplus and converted to bike lanes VDOT should complete a 527 study to prove that the capacity won't be needed as houses and offices are built out consistent with the adopted Comprehensive Plan.

John, I'm not sure I have heard/seen any research or justification guiding your comment that the removal of lane miles is a "principal source" of congestion in the Washington DC area. I have however seen plenty of research indicating that steady population increase in Northern Virginia, as well as the increasing distance between homes and workplaces HAVE in fact added to existing traffic volumes in turn leading to some roads being at or over capacity. That is the more concerning fact to me. We should be focusing on a more sustainable development pattern that does not require long distance commutes for massive amounts of the population.
I also feel that your understanding of the Chapter 527 process might be misguided. The simple act of changing the functionality and lane configuration (not width) shall not and will never be a trigger for a Traffic Impact Analysis. The option of accommodating more traffic on this roadway is still not out of the realm of possibility since the pavement width was not changed. That being said, the intended density specified in the Fairfax County Comp Plan for the area around Lawyers Road at final buildout is not significant (single family homes, with a few higher density residential areas to the north). It is unlikely that the 4 lane, rural road typology that previously existed and that was specified in the original 1980s era, reston town center plan is required to safely and effectively accommodate traffic.

The 1965 transportation plan hangs on my wall. It was prepared based on population and employment projections for the year 2000 that were surprisingly accurate: population was exactly right, there were 50,000 more jobs in the MSA in 2000 than had been projected in 1965.
Unfortunately, thousands of lane miles of roads throughout the MSA shown on the 1965 plan weren't built including 4 bridges across the Potomac. Run any traffic model available; when that many lane miles are removed, gridlock results.
As to added distances, since 1956, localities have been engaged in a continuous series of downzonings eliminating thousands of houses that could have accommodated the employees' families in close proximity to the job sites. Instead large percentages of land area have been zoned for 1, 3, 5, 10, 20 and 50 acre minimum lot sizes forcing the average worker to travel further and further to find an affordable single family home, which is the preference of 80% of the market.
A 527 study looks at changes in demand and changes to capacity needed to accommodate demand. It can just as easily be used to analyze changes in capacity and the subsequent ability of the system to handle expected demand.

Lawyers (combined with Soapstone, Steeple Chase/Colts Neck and Twin Branches) provides access to the employment site along the Toll Road east of Reston Parkway from the south. As the TOD projects come on line, volumes on that group of roads will increase. Losing the capacity converted to bike lanes will lead to congestion on those roads.

Bike lanes are certainly not a trend. They've been in use around the U.S. for many years and surveys have shown that cyclists feel much more comfortable riding when they are present. If we ever expect to have more than a small number of people using bicycles for transportation we need to provide better facilities for them. As pointed out above, most of our trips are short and could easily be taken by bike. Most people own bikes. We have built our communities around cars; let's change that trend and build a few critical facilities for cyclists and maybe we'll see more of them on the road. Even without dedicated facilities I've seen many more people riding in the road in the past year or so. More people are discovering the advantages of getting around by bike and not being stuck behind the wheel of a car.
The road diet on Lawyers Road has been huge success. VDOT recently reported that "In the four years prior to the road diet, Lawyers averaged 15 crashes per year. In the first year after the road diet, we observed only 3 crashes in the same segment of Lawyers, for an 80 percent drop. It is too early to make any firm conclusions about the safety results, but the initial trend is very encouraging." The road has changed from a racetrack where motorists turning left were getting rear-ended to a much calmer, safer road for everyone. It's so successful that a similar treatment is planned for Soapstone Drive when it gets repaved later this summer.

"stuck behind the wheel of a car"?
Right, where's it's cool in the summer, warm in the winter, dry in the rain and has those bright tail and headlights at night to let people know where we are and show us where we're going, has room to carry several passengers, the dry cleaning and family groceries and can get through in the snow. None of the things that are true of a bike. Which explains why bikes will never exceed single digits for the percentage of trips they will represents. Thus, no reason reduce capacity on streets like Lawyers or Soapstone to give 25% of the pavement to 1% of the trips. Bike lanes should be put on roads like Foxglove, Blue Spruce and Riders.
The Lawyers diet will be a success right up until moment there's a head-on fatality in the suicide lane.

Re: Mr. Farrell's comments, there will always be people who choose to be stuck behind the wheel, sealed in their cars to get around. They do pay a heavy price for that privilege; about $8,000 a year to own and maintain a car vs. $100-$200 to do the same with a bicycle. For those who ride in the summer, it's usually relatively cool in the morning during the ride to work. In the evening it's not as hot as mid-day and riding in the heat is bearable if not going to work. We're lucky to have mild winters and can ride nearly year round. Some of us prefer riding in the winter.
Most bike commuters have powerful lights for riding at night. Some of us have trailers or cargo bikes to carry groceries or other larger loads. If you think about it, it's rare that most of us need to haul stuff in our cars, and when we do, the loads are often small. We travel to the farmer's market every week and can carry the small loads on our bikes with no problem.
Even so we also own cars and when necessary will drive them. Bicycling is not a 100% solution for all our transportation needs. No one claims it is; it's a reasonable option for short trips that many, many people want to use. We just need better facilities to use it. Fairfax Co has embarked on a bicycle master plan which will provide a guide for the future, and it's about time.

Bicycle tail lights and headlights are as bright as the car equivalent?
It's been 80+ many mornings this summer at 8 am. Never mind for the lunch hour trip. Few employers have showers at the office.
How many Moms are ready to risk their toddlers on the back of a bike. The few times I see one perked over the rear wheel I cringe.
Stop it. Your zealotry is undermining your credibility.
Cars are more comfortable, convenient, commodious and safer.
You want bike lanes on low volume street like Twin Branches and Glade that are extra wide two lane roads with extra low volumes. Have at it.
Eliminating through lanes for bike lanes is misappropriating a public resource to pander to a tiny minority.

I bike to work in Fairfax City whenever possible. I ride in traffic along both Braddock and 123 in addition to side roads. Surpisingly (at least to me), most drivers share the road without visible grief, though there are the ones that hate the thought of anything without a gas engine being allowed on the road.
I would enjoy a bike lane or two, but it wouldn't affect my own commute too much. The John Farrells of the world will honk and hog the road when there is no lane, and they'll curse the lanes when they are.

Mike -As I already wrote, I'm happy for bike lanes so long as they don't reduce capacity on a road network that's already severely undercapacity. It's great that we paid for the FFX Parkway to have a parallel trial for bike riders to use.
I happily reminding bicyclists, when they run stop signs and red lights and ride 3-4 abreast, that the rules of the road apply to them too.

@John: No one is telling parents that they have to bike their kids to daycare. But if roads weren't overengineered to be mini-highways and if they were actually designed to be safe and convenient for their host communities (rather than widened and maximized for cut-through traffic from sprawled development looking to have its transportation provided by someone else), biking a kid to school wouldn't be extraordinary.
Cars are important, but they are an expensive form of transportation for residents and for the city, and Fairfax especially would benefit with adequate facilities for bicyclists to get to town, GMU, or the Metro station. Just because you don't want to bike anywhere because it's hot or cold or uphill or you don't have a gym membership or shower at work doesn't mean there aren't many multiple-car households around town who would really appreciate the savings if they could get by with one less car.
I was born and grew up in the area, and until age 16 or so, you're pretty much stranded transportation-wise or reliant on other crazy 16-year-old drivers to get around the area. I want my kids and local high school and college students especially to have a safe and cheaper alternative to getting in a car every time they leave the house.

It's days like today, after the earthquake, that most cyclists are glad they chose to bike to work. They know how long it will take to get home, which is the same every day. Motorists almost never know how long it will take to get somewhere, especially during rush hour, so they have to plan accordingly.
