Bike Safety, Part II

In a previous post I made an attempt to quantify how safe bicycle commuting was for me, personally. I concluded that for my specific situation it was probably safer than driving, and that the lifetime risk of death was at an acceptable level.

Since then, the north end of the Burke-Gilman trail has been closed for much-needed repairs and improvements, and the lack of a good detour has forced me out onto the streets for a shorter but more harrowing commute down the Interurban corridor. After two months of deprivation I have a renewed appreciation of how great an asset the Burke-Gilman trail is. And an incident this week underscored just how hazardous it is when bicycles and cars share the same pavement.

The Interurban trail is a work in progress. I get on just north of 185th and enjoy uninterrupted (if less than ideal) trail riding until 145th. Then it's onto the streets to 130th, back onto a dedicated trail, and then back to the streets for good at 110th and Fremont. This is where things get dicey.

Fremont Avenue north of Woodland Park is a low-traffic street, presumably good for bicycling. The problem is that every minor intersection is uncontrolled, with a small central barrier serving to slow traffic and suggesting (but hardly enforcing) a roundabout pattern of traffic flow. Bicycles can cruise straight through - but they shouldn't. In most cases visibility down cross-streets is poor until you get really close to the intersection, so the only way to ride safely is to cross at low speed. For southbound riders the geography is uniformly downhill from 105th through 85th, so this means continual braking.

On Thursday this week a young woman passed me at 105th. Concerned, I watched her slow down as she approached 104th, so I stopped worrying. Six blocks later I found her on the ground, in the middle of the street, with a car stopped by the central barrier and a concerned couple ministering to her needs. I didn't see the accident, which evidently was mercifully minor, but it was clear what had happened. My unease with the route increased.

South of 85th I head east to Greenwood, where I share the bike lane with buses and opening car doors. It concludes with an exhilarating, high-speed bomb down Fremont Avenue south of Woodland Park where the safest course of action is to share the lane with traffic, which in general is aware of and quite tolerant of us numerous bicyclists.

I haven't tried to recalculate my odds of survival over the next 10-20 years, since this is a temporary situation, but in just two months it has become abundantly clear that my ride is far less safe now. Unfortunately, just about the time the Burke-Gilman trail is scheduled to reopen my company will be moving its office out of Fremont to the International district, way down on the south end of downtown. I haven't tried to work out the best route there yet, but I really needn't bother: there's no question it will be much worse, worse even than my current commute.

Two months of street riding have me all but convinced that this is no way to spend two hours of every weekday. Sad though it is, I think my bike-commuting days may be numbered. My tentative plan now is to bike six miles to Edmonds and take the Sounder train downtown when the weather is good, and walk a mile and take a Community Transit express bus when it isn't. I'll have to get in my biking some other way.

I've worked my way through the Kübler-Ross stages of grief scale (though I think I skipped stage 3, Bargaining - just who would I bargain with?) and have now arrived at stage 5, Acceptance. I'm already finding upsides: less joint pain, more time to read, less total commute time. But I know I'll have to find some other way to stay in shape, and I'd like that to involve bicycling in some manner. Weekend rides with my wife to Redmond for breakfast? The occasional bike tour? Maybe I'll even finally sign up for one of the Cascade Bicycle Club rides I read about in their monthly newsletter.

Whatever happens, 2011 will go down as a Year of Change: a daughter married off, our son heading off to college leaving us in an empty nest, a historic Scandinavian tour...and the end of a decade of bicycle commuting.

Interurban Trail - Where Are You?

On a recent day off from work my wife and I decided to check out the Interurban Trail north of Seattle. According to maps obtainable here, the trail runs continuously from just north of Lake Ballinger in Mountlake Terrace all the way up to Everett. Sounded like fun.

We easily found the south end of the trail and jumped on. It took us through some pretty woodsy areas and past the outdoor batting cages of Funtasia on 220th. Then, after only a mile or so, it abruptly ended on 212th. No signs were posted anywhere suggesting where we should go next.

So we worked our way north on side streets, hoping to intercept the trail again at some point. Unfortunately I hadn't brought a map with me, so it was pure guesswork, and by lunch time we still hadn't found it.

After lunch we headed back by a different route and happened across a different section of the trail purely by accident. We hopped on, and in less than a mile it too ended, again with no signage of any kind. But we recognized where we were, and this time we were able to navigate along the streets (two left turns and then a right) to the first segment of the trail we had ridden.

Alright, I know this Interurban Trail is still a work in progress, but does no one in Lynnwood have any concept of helpful signage? If not, I suggest you take an educational tour of the Burke-Gilman trail and note all the helpful signs posted along the way.

We hope to give it another try some time this month, and this time I'll take a map with me. It feels a little like leaving civilization and embarking on a quest, like Lewis and Clark's search for a route to the Pacific. I'll make sure to have a camera along to record our adventure. Wish us luck!

Why the Zig-Zag Route?

A new section of the Interurban trail opened about two years ago, offering a welcome overpass over the busy intersection of Aurora and 155th, and another one over Aurora itself just a long block to the north. For a north-south commuter like me this is a great addition to the trail system. In 1993 I used to commute this route without any trails, and the best option at the time was to ride right on Aurora between 155th and 145th. Ah, to be young and foolish!

So why am I getting ready to complain? Am I never satisfied?

Here's why: to cover the short stretch from the southwest corner of 155th and Aurora to the east side of Aurora at 157th, a biker must negotiate a tight 180° off-ramp that sends you away from where you want to go, around a blind corner at the base of the bridge to head back north again, to a stop sign that doesn't seem to serve any useful purpose (since changed to a yield sign, through a fit of common sense), back up a tight 315° on-ramp, and finally down a more rational north-facing ramp back to street level.

Walkers can shorten the trip by using stairs, but bikes (and wheelchairs) have to follow this tortuous route. I have to ask: why all the zig-zags?I can think of a couple reasons, both of them cynical:

1. The powers that be do not want bikes traveling at a high rate of speed, so obstructions were put there intentionally. There is a precedent for this: the Burke-Gilman trail through Lake Forest Park was "unstraightened" to slow bikes down as they approached driveway crossings. This is a sin that appears on its way to being corrected; why do more of the same in Shoreline?
2. The powers that be are clueless about what makes a suitable bike trail.

Although the situation at 155th and Aurora seems almost intentionally obstructionist, I'm leaning toward the second explanation, chiefly based on evidence from the very same trail just a mile farther north. Between 175th and 182nd the trail makes its way along a wide grassy expanse between Aurora to the west and Midvale to the east. Though the two roads are perfectly straight along this stretch, the trail meanders left and right between the two, no doubt for obscure aesthetic reasons. Just before 182nd it lurches to the right towards Midvale, lurches left across 182nd, followed immediately by 90°, 135°, and 45° turns before heading north again. What the...?

It looks for all the world like someone penned in a gracefully meandering trail to serve as counterpoint to the surrounding Cartesian asphalt grid, then smacked their head at 182nd and said, "Whoa, there, we can't cross here next to Aurora, it's too dangerous! Better head over to Midvale!" The result just seems too lame to be diabolical; it must be incompetence.

So as a public service, I hereby offer my expertise as a dedicated bicycle commuter to the poor clueless schmucks trying to spend the trail dollars we've approved. I have a couple principles that, if followed, will make life better for everyone:

1. Straighter is better. Meandering trails are great for hikes in the country; for commutes through the city they just mean added distance and reduced speed.


2. Wider is better, too. Pedestrians are safer, collisions are reduced, and bikers are happier.


3. When bike traffic exceeds car traffic at an intersection, aim the stop signs toward the cars, not the bikes.


4. Sectioned concrete is great for sidewalks, but it's terrible for bike trails. Use asphalt, please.

In many places bikes are still not seen as real vehicles, doing real business. Eventually the word will get out that there are large numbers of us for whom bike riding is a way of life, not a weekend diversion. Shoreline hasn't got the message yet, but the changes coming to the Burke-Gilman trail in Lake Forest Park give me hope that other places have. The future is on our side. Let's all do our best to make it come sooner rather than later.
