I found a similar, but not the same, map from 1896 published in the Washington Times that I blogged about.

"Charmless" Signage in Arlington (VA)

I was reading a story in the Washington Post about changes coming to Arlington County council in the new year.

There is this, with a quote from Council member Libby Garvey: Garvey warned that local government should not “overstep our role and risk stifling innovation,” particularly in regulations such as the sign ordinance, which took more than a year to revise. “Part of the charm of Arlington,” she said, “. . . is how not standard everything is.”

I am not sure what "sign ordinance" is being referred to, but I don't much care for non-standard, inconsistent application of signage to traffic control affecting cyclists - but I don't have to go far to find some, given a recent change to the trail near my house.

Down the street from my house on South Dinwiddie Street, there is a trail that is an offshoot of the WO&D trail, that is parallel to the Lucky Run (stream).



The trail is shown in the image above, with the red line. Somewhat unusual I would say, there is a standard sidewalk and crosswalk at the intersection, then 40 or so feet back on S Dinwiddie, there is the crossing for the trail. It is not painted as a crosswalk with zebra stripes, but there are some dashed lines to show it is there to drivers. There are yellow yield signs controlling pedestrians and cyclists on the trail who would cross S Dinwiddie St.

Meanwhile, just a quarter mile away, the trail crosses S Wakefield St in a similar way but the traffic control is completely different.



These stop sign appeared about a month ago - previously there was not signage here controlling pedestrians and cyclists on the trail where it crosses S Wakefield St. (Yes, the stop sign are not full size, but sort of toy size for some reason.) And the crosswalk is painted with full zebra stripes.



Here you can see the situation, much like at S Dinwiddie St, with the trail crossing set about 40 feet back of the crosswalk that is the intersection.

I don't understand how it is that Arlington County thinks these intersections are supposed to work successfully. In general, if a motorist sees me in the "not quite a crosswalk" for the trail crossing, they stop - but I can't count on it. And apparently at one of the intersections (Dinwiddie) I am merely to yield, but the other (with full zebra stripes!) requires a full stop! WTF, to use the vernacular (or vulgar - whichever).

Consistency in these matters could be a good thing, even in quaint Arlington County. This is a real safety issue, after all.

Per Arlington VA Police, Cyclist=Scofflaw but Motorists are OK

Cyclists need to obey those darn laws


Motorists? They just need to be careful

This is of course absurd. It makes sense only if cyclists are presumed to be scofflaws and motorists are law abiding folks who probably would be well advised to be careful of those scofflaw cyclists. In fact there is no evidence at all that cyclists are more (or less) law abiding than people driving cars. There is considerable evidence of course that when cyclists or motorists do dumb things and have accidents involving cyclists and cars, the cyclist suffers much greater consequences.

This is particularly ironic given the location, which is right where a major bike trail crosses a busy street. Under VA law, if the cyclist is required at this location to walk his bike and not ride in the crosswalk then this needs to be specifically posted, otherwise the cyclist is free to cross the street on his bicycle in the crosswalk. The obvious for accidents with the bike trail+crosswalk across Walter Reed is with left-hook and right-hook turn accidents from cars turning from S Four Mile Run Drive where the driver doesn't see the cyclist in the crosswalk because the motorist failed to exercise due care.

Ugh!

Studded Tire Performance in Icy Weather

Photo from several years ago, but bike and tires look same now

I have a 15+ year old heavy ChroMoly Giant mountain bike with studded mountain bike tires - they were sold under the NashBar brand, but were made by Kenda (I think). 1.95 (or really 2) inches wide. There are two rows of studs, kind of alternating in position relative to one another looking across the tire. They are far enough out from the center of the tire that one can significantly influence how many studs may be in contact with the ground by changes in the tire pressure.

Three days ago it was snow, not ice, and I had the tires at 55 pounds per square inch. I made pretty good time but the studs were not really necessary. Two days ago the conditions were much more icy for about half the ride, in other words, the part that is NOT MAINTAINED BY THE NATIONAL PARK SERVICE (unlike Arlington County, which pretreats its bike trails, God help us). I rode to and from work with the tires inflated only to 40 pounds per square inch and clearly that improved the studly-stickiness of the tires - very little sliding around. On the other hand, on bare pavement, the road resistance is pretty noticeable (and unpleasant). A compromise.


Typical Mount Vernon Trail conditions - thanks for nothing, NPS

This morning I increased the pressure to 50 pounds per square inch since I was hopeful that the trails would be more clear today, but there were still significant areas that were covered from one side of the trail to the other. 50 pounds per square inch was too much to have the same kind of good traction that 40 provides, but I chose to ride along the edges of the trails where there was less bare ice or in a few cases off on the frozen ground along the trail. The improvement in rolling resistance by having more air in the tires made up for a small amount of slow riding in the few really bad spots.

I have now had these studded tires for something like eight years - maybe more. Of course there was at least one year where I didn't use them at all, but I don't ride them much. Originally I thought that if I rode what must be cheap metal studs on lots of bare pavement that I would pound them flat (ruin them) in no time, but in fact they seem to show little wear at all.

Last year I realized that I had lost several on each tire - they are kind of like short thick nails, with a head at the opposite end from what sticks out of the tire. Nashbar sells replacement studs with a tool for installing them and that works fine. I am now riding with a full complement of studs.

I see that there are road tires with studs - the rows of studs are of course much closer to each other. I assume that overall in most urban conditions these would be faster but for now I will stick with the mountain bike approach.

Arlington Trail Snow Removal ROCKS

At long last, parity (if only in Arlington)

Clear roads and clear trails, on the same day. Thanks County government!!


Where Arlington County trail clearing ends

I stopped on my way home to take this photo. This is where Arlington County's trail clearing efforts came to an end - the Mount Vernon Trail maintained by the National Park Service has had nothing done and tomorrow will be an icy mess.

My photo doesn't show it clearly, but it is pretty funny (to me) how Arlington's mini-plow went in a nice little circle clearing the trail before heading back into Arlington.

I suppose the National Park Service will do something when hell freezes over.

Arlington County Plows Bike Trails Early

Arlington Country bike trail along Four Mile Run - plowed at 6:45 am

The DC streets I saw, however, were not plowed at all. Crazy.

Arlington County Pre-Treats Bike Trails

Tomorrow we may have and inch or two of snow, starting around 4-5 am. Maybe.

There had been discussion of more allocation of resources to clear snow from "mixed use" (that is, bike) trails, but I had not realized this could include pre-treatment before the snow. On my way home today, turning off the Mount Vernon Trail onto the trail along Four Mile Run, I noticed the tell-tale lines on the pavement indicating some kind of vehicle had come through and applied some kind of treatment in advance of the snow's arrival.


Looking away from Shirlington, you can see the application of some sort of liquid treatement both coming and going

Apparently this is where the vehicle turned around since a fair amount was spilled.


Looking towards Shirlington, you can see that the narrower trail means just one direction of application

I have no idea how helpful this will be. Find out tomorrow, most likely.

Arlington County (VA) and Trail Plowing

March 9 I sent the following as an email to the Arlington Bike Coordinator; later I submitted a revised version to the County Board on their website.

It appears that over the winter the County decided to switch from salting trails to plowing. (I leave near Rt 7 and Walter Reed and ride down the trail along Walter Reed, then down the trail along Four Mile Run to the Mt Vernon trail and then in to DC that way.)

I am surprised by the timeliness of some of the plowing that happened - in particular, the that runs parallel to Walter Reed between Rt 7 and Arlington Mill Drive was plowed recently very quickly after the snow - this makes a lot of sense since if you are going to plow trails (and not salt), it should happen fast before the snow turns into ice from people walking on it.

The different this past week was very noticeable between the trails I use in Arlington and the Mt Vernon Trail, which was untreated and unplowed. The main thing was that the trails that were plowed become clear and useable by a regular bike quickly and the Mt Vernon trail was only rideable until Thursday either by riding very carefully or by having a bike with studded tires (which I have).

Plowing isn't a perfect solution - Tuesday in particular some trails had been plowed before my morning ride but the result was that the asphalt (with the 15 degree weather) was coated with a thin sheet of ice instead of a thicker layer of ice and snow so that a regular bike would not have traction - it would have been impossible to ride without studded tires. But by that afternoon the situation was already better, and Wednesday morning the Arlington trails were rideable (with care) while the Mt Vernon trail was not. Still, I think plowing is better than treating with salt etc.

The plowing is good. Thank you.

Plowed trail near my house - makes a big difference!

This kind of systematic effort to clear trails used by cyclists (and others, of course) following snow storms is new this year in Arlington, and there was enough snowy weather for some experimentation. The first round was to use salt/road treatment type applications on the trails, which isn't great if you want to walk a dog using the trail and also is hard on the bicycle and the surrounding environment since the salt/chemicals aren't confined to the trail (asphalt). Plowing is a lot better, and the County shifted to that, which is great.

Better still would be to have a little less snow.

Limits of Cold Weather Commuting

As in, my limits. Well, my limits and the limits of my cycling equipment.


My ice commuter, for better or worse

Today was the second day I rode back and forth the ten miles between my house and Capitol Hill with the trails pretty icy and in reasonably cold weather, particularly in the morning. In my years of commuting in more or less all weather, it is fairly unusual to have sustained cold such that the trail conditions didn't change that much between two days. In a few places some salt had cleared areas, but it was not like the second day was a huge improvement. (Mostly the trails are not treated.)

This morning it was cold, for here at least, at around 12-14 F - around -10 C. It was colder than yesterday and since it took me over an hour to get to work, my fingers were starting to get cold on one hand - but overall my cold weather biking clothes work OK at least down to this temp. But I need to keep moving, spinning, to maintain my warmth.

The bigger problem is with my bike and my fitness (my "fitness" in the broader sense of being physically ready for such an endeavor). The bike is an old Giant that I have only ridden in the last few years when I want to take advantage of the studded tires I have mounted on it, and that's it. The bike could use some adjustments. The rear brakes in particular don't work well in these conditions and of course when it is slick the front brake can't be used (much) without instantly causing a crash so the poor rear brake performance isn't helpful at all. (I should fix that!) The 1.95 inch wide tires with the studs are lovely for traction when the surface is mostly flat/smooth but if there is accumulated snow or snow+ice they have a terrific amount of road (or I guess snow) resistance - the width isn't helpful.

But it does work. Two days running I rode back and forth on a lot of slick surfaces and didn't fall once. And I got back and forth.


The Gravelly Point area of the Mount Vernon Trail; another riding north as I head south

I don't see too many other riders on the trail on a day like this. Today I saw two riders coming the other way on my ride home (total) - one was a commuter and the other fellow just seemed to be out enjoying the fun to be had. The photo above shows the commuter I saw, chugging along. He did not, I think, have studded tires - he was riding a cyclocross sort of 700 size tire bike and was hugging the right edge of the trail. I am familiar with this approach - basically you stay away from where other riders have been riding and especially stay away from icy sections. The narrow tires cut through the snow OK and you have traction but it very tiring to maintain this kind of straight-ish line.

My approach with the wide mountain bike tires is to stick to the middle where the snow is pounded flat and where there is compacted snow on ice and try to skirt as much of the clear ice as I can. The studded tires will allow some riding on clear ice, but you can't brake or steer (much). And sometimes you hit a bump and the bike simple slides. The studs aren't a perfect solution.

It's an adventure (or something like one, for me) but I'm glad to have the weekend now to rest up. I don't know if I could do more than two days running of this. I was unhappy this morning to pass a guy walking his bike on the Mount Vernon Trail near the airport, on one of the bridges - he had a very nice bike, but apparently was having no luck staying upright. He didn't look like he was dressed as warmly as me, and walking . . . I didn't have anything to help him with this problem, so I just kept going.


A snow-bike patent for a set of attachments from 1900 - but my problem was ice, alas

I have a sort of cyclocross bike that is presently out of commission with disk brakes - I should get some studded tires for that thing when they are on sale so I have a bike to ride in this kind of weather with working brakes and have narrower tires to cut through snow. For next year. Yeah.

Plywood Trail Replacement Wearing Out

The problem as of June 1 2013 - 100s of pounds of cyclists pounding these plywood sheets, day after day

About 1 3/4 miles from my house, along Four Mile Run on the bike (or mixed use) trail, Arlington County installed a temporary (one hopes) bypass storm drain pipe across the trail during the first week of May (2013). They built a ramp (or bridge) over this so that the trail is still usable. It is built out of plywood and the construction techniques leave something to be desired now that it is clear that it is going to be up for longer than say a week. The construction, not great in the first place, is gradually failing. Lawsuit alert!

The original execution had plain sheets of unpainted or treated plywood such that when it rained they were a bit slick. It struck me as obvious that the boards should be painted or treated with something and at that time throw some sand into the mix to add some traction. So I contacted this County with this brilliant observation:

My comment, made May 8 2013

Subject : WEBSITE COMMENT: Temp bridge over pipe -- ATTN: trails

Comments : On the bike trail along s glebe rd about 1/4 mile s of I-395 there is a new temporary plywood ramp over a pipe. This ramp is getting tire residue and is plain wood. When wet it is slick for bicycles. Can't you paint it and throw some sand on the paint for safety?

Thank you.

The County is fairly responsive. I was slightly amused by the notion that "exterior surfaces are slippery when wet" as being something they couldn't address but whatever.

First reply, May 9 2013:

Michael,

Thank you for writing about the ramp on the Four Mile Run Trail at South Glebe Road. Most exterior surfaces will be slippery when wet, but I will forward your observation to the unit who is working with the contractor. They may have a surfacing material with more traction for the ramp.

I was surprised (and I suppose pleased) to get a follow-up message soon after.

Second reply, May 10 2013:

Good Morning Michael,

Again, thank you for notifying trails of the condition of the bike trail ramp during the rain. The contractor has placed non-skid mats on the ramp to increase friction when bikes ride over it. Please see the attached picture for your reference. If you have any additional concerns in regards to the temporary bike ramp on S Glebe Rd, please do not hesitate to contact me.


Photo sent me by County showing how they solved the problem of slickness during rain (as of May 10)

This is a case of what happens when one (in this case me) is not very clear. I don't really see how strips like this solve the overall problem since there is plenty of area that is not covered by the traction material. And it doesn't address what is turning out to be more of a problem, which is that the untreated/unpainted boards are suffering under a higher level of pounding/usage than the County or this contractor imagined. I would not have guessed that a temporary structure of this quality was intended to serve this long - and apparently longer. Who knows how long.


June 1 - looks OK at this distance, although one railing clearly bowing in


Closer examination reveals somewhat wavy deck

The contractor chose to run the plywood longwise but it wasn't wide enough to cover the entire deck, so they have two sheets of plywood, one larger and one smaller, running side by side. Amazingly dumb. It would have been much better to run the plywood sideways so there is no "seam" running the same direction as the direction of travel.


Looking in other direction, clear that main sheet of plywood coming up

In the first picture in this blog post, another problem is clear, if you think about it. Cyclists are mostly are not used to riding on ramps like this and it isn't that wide - so they pretty much want to be in the middle (notwithstanding the little yellow striping that suggests this is some sort of miniature divided highway). Because many cyclists are apparently not used to be presented with problems of this sort, they try to cross in both directions at the same time as other cyclists or as pedestrians even though common sense would suggest that it is a bit risky. The County supplied signage warns as you approach in one direction "bump" (???) and "slow" (that's OK, I guess) in the other.

I will send the County a link to this blog post and perhaps they will make it better.

Or not. We'll see. . . . .

Capital Bikeshare Adds Shirlington (VA) Station Today

Not there this morning, there during evening commute

This is about a mile from my house, which is closer than I thought Bikeshare would be getting at this point. I haven't been able to think up a case where this would be helpful or useful but intuitively it seems like a good thing that there is one here. There is one right near my office on Capitol Hill. Who knows ~~~
