Arlington County installs new bike signal on Custis Trail
On Tuesday Arlington County activated a bike-only signal in the Rosslyn area of the Custis Trail at the corner of N. Oak Street and Lee Highway.
This is one of the several intersections on the trail's "Rosslyn Hill" section, which is definitely the most dangerous section of the Custis Trail. Numerous cyclists and drivers have collided at some of the section's crossings in the past.
This crossing already had a walk/don't-walk pedestrian signal, which would inform cyclists about the status of the cross-traffic. Since right turns are prohibited on red, cars waiting on Oak Street will not create a conflict when the bike signal is green and the pedestrian signal is in the walk mode.
Cyclists need to watch for right-turning traffic from Lee Highway onto Oak. Although these cars are supposed to yield to bikes and pedestrian in the crosswalk, cyclists should double-check.
The above photo shows the bike signal still green while the pedestrian signal is flashing "don't walk" with 3 seconds left. Since bikes can cross much faster than pedestrians, this makes sense. There is a brief yellow bike signal that illuminates for 2-3 seconds before changing to red.
I did not observe bicycle behavior at this intersection with the new signal. The signal is green for much more of the time than it is red, probably 75% of the time. Most of the time cyclists will be able to proceed through this intersection without pause. It will be interesting to see how cyclists behave with this new signal: if they will treat it like a car would treat a traffic signal or more like an "Idaho stop."
It's great that Arlington continues to work to improve the cycling environment. Hopefully this new signal will increase safety and awareness.

49-720. STOPPING -- TURN AND STOP SIGNALS. (1) A person operating a
bicycle or human-powered vehicle approaching a stop sign shall slow down and,
if required for safety, stop before entering the intersection. After slowing
to a reasonable speed or stopping, the person shall yield the right-of-way to
any vehicle in the intersection or approaching on another highway so closely
as to constitute an immediate hazard during the time the person is moving
across or within the intersection or junction of highways, except that a
person after slowing to a reasonable speed and yielding the right-of-way if
required, may cautiously make a turn or proceed through the intersection
without stopping.
(2) A person operating a bicycle or human-powered vehicle approaching a
steady red traffic control light shall stop before entering the intersection
and shall yield to all other traffic. Once the person has yielded, he may
proceed through the steady red light with caution. Provided however, that a
person after slowing to a reasonable speed and yielding the right-of-way if
required, may cautiously make a right-hand turn. A left-hand turn onto a
one-way highway may be made on a red light after stopping and yielding to
other traffic.
(3) A person riding a bicycle shall comply with the provisions of section
49-643, Idaho Code.
(4) A signal of intention to turn right or left shall be given during not
less than the last one hundred (100) feet traveled by the bicycle before
turning, provided that a signal by hand and arm need not be given if the hand
is needed in the control or operation of the bicycle.
------------------------------------------------------------
In short: You have to slow down and yield for a stop sign. You have to *stop* for a red light.
Just a reminder.

Maybe in Idaho, but in the Commonwealth the law is cyclists must STOP on a red light, and wait for a green.
I've watched this exact section of the trail already and cyclists and pedestrians still enter the intersection when the light/do not walk are both red.
I plan on contacting the police and asking that they start issuing tickets/warnings to cyclists and pedestrians that violate these signals.
That being said, I'm thrilled these signals have finally been installed. This intersection is a deadly one.

The light is triggered by traffic going North on scott turning west on lee -- not crossing the bike path. But there is no left turn signal pattern. It is a simple cross traffic pattern. This means that 90% of the time the light is red for the bikes, it is red to let north bound scott st traffic turn west on Lee hwy.
Beyond being stupid, this breed a different problem. It trains the bikers to ignore the light. The light is a product of faulty traffic planning. It doesnt work. It stops significant traffic flows for no reason. And as a result, bikers just ignore it.
A little bit further east on the Custis, at Lynn St, no biker ignores the light, because the light is real.
Pointlessly imposing car traffic patterns on bikes for no reason only creates further problems.

Personally, I don't mind treating a stop sign as a yield sign as a biker. It is silly to make bikers stop at empty intersections. A slow down is enough. I disagree that bikers should be allowed to stop and go through a red light. It's dangerous.
Overall, bike signals are good. They help create clarity.

Drivers can't see up the hill because the building blocks the view of the trail. The cause of almost every accident is that of the cyclists blowing the stop.
Hopefully the dedicated bike light will help, but im fairly certain that the majority of cyclists will only stop/pause there and there will still be accidents.
Cars that have the green know it is only a short light and are often going 25 mph through the intersection when making a left.

The first part sounds exactly what pedestrians and cyclists must do on crosswalks.
"After slowing to a reasonable speed or stopping, the person shall yield the right-of-way to any vehicle in the intersection or approaching on another highway so closely
as to constitute an immediate hazard"
Thats exactly how most crosswalk laws around this country are ridden.
Re: Togea:
Why are cars welcome to run red lights legally (right turn on red) so long as the intersection is clear, but if a pedestrian lay foot on the asphalt with a red signal THEY ARE A TERRIBLE JAYWALKER!!!!
Seems like the law makes no sense.
"I just remembered, there are painted stop signs on the ground in both directions, so cyclists are supposed to stop even if the light is green. "
That also makes no sense. Coming to a full stop when presented with a green? That's a recipe for disaster. Go ahead, do that next time you're driving and approach a green light and see what happens.
If the government installs a sign that says "Jump" at the edge of a bridge, doesn't mean you should pay it any attention.

At that intersection there is a "no turn on red" sign.
As you know cyclists are supposed to obey all traffic signals, just like drivers. If there is a stop sign (like at this location), cyclists must stop. If the light is red, they should wait until it is green.

I live on Scott St and I am a runner and a biker. I'm very familiar with both the Scott and Oak crossings.
Scott St is green to bikers 90% of the time, not red 90%. The reason is that there is a lot more traffic on Lee Hwy. There is significant danger to bikers from cars coming South down the hill on Scott. There are warning signs for cars to watch for bikes, but the vegetation blocks the view of these signs. There should also be a sign on Lee Hwy for cars turning right to yield, as this is a big area of vulnerability.
That said, my opinion is that Oak is the more dangerous intersection. Bike speeds are much higher. Bikes crossing Scott going East have just started to go downhill and haven't picked up much speed. Bikes crossing Scott going West are often laboring. Oak is very different. Bikes are either speeding at the bottom of the hill or trying to build up momentum to get up it. While the visibility for cars on Scott may not be great, it is much worse on Oak.
If there is to be a cop handing out tickets, Oak would be the obvious place to focus the efforts. Cars that turn right illegally or block the bike path (my personal pet peeve)should get tickets and bikers who fail to check for traffic (or cross in front of a car) on a red should get a ticket. The solution can't focus on only one group at that intersection and the things my neighbors have suggested are udderly laughable - speed bumps for the bikes. Could you imagine? For Scott, the focus should be on the cars, not the bikes.

Damn straight. Great post overall.

Oak st is a popular spot for cops to hang out, but they mostly are just ticketing speeders on that stretch of lee highway.
I've noticed since the bike lights went in an increase in the Lycra-clad on lee highway itself. Nice weather, or getting confused by bike lights? Perhaps a bike lane on the right most lane. Except for rush hour, Lee highway could support that. The danger is bikes on Lee Highway below Oak (and the sound barriers)

I think this is great, but there is a huge problem that I see a few times a week when I am driving on Lee Highway around this area of Curtis Trail. The problem is that cyclist are using the road instead of the designated bike path! It slows down traffic and is extremely dangerous. Is it against the law for cyclist to be using the road while there is a bike path right next to the road?
Thanks,
Kyle

At the same time, cyclists need to honor the rules of the road (in particular the blatant signage, as the new light mentioned in the article) to stop, yield, or dismount, to hold up our end of the bargain.
