Default Traffic Light decoder key

I was reporting some lights along my favorite routes today that did not recognize bikes. It turns out Washington Co. is responsible for most of those.

I was given the link to the map that defines who owns what in traffic control.

If you are tired of run-ins with your nemesis signal light, please contact the public works department responsible for that intersection. They should come out and recalibrate the sensitivity of the triggers and paint a little bike symbol on it to show where to wait.

Will they also increase the length of green for those lights that DO trigger for a bike?

So many intersections have such short greens I'm almost not able to clip in and pedal across before it goes red again.

Barrows Rd crossing Scholls Ferry as well as 130th crossing Scholls Ferry.

They should if you have enough evidence to support your claim. I have the same problem with quite a few 5-lane'rs.

Truly awesome resource!
The map does not seem to indicate type of sensor: loop, camera or other.

Other than physically being there is there any simple way to tell what it is?
Like everything by a certain installer, owner or in an area is one type or an other?

I must say that I like camera based traffic light triggers. They are really nice for night rides in low traffic. With a helmet light on steady you can trip them well in advance so you never have to slow down.

In particular I used to commute down Millikan crossing at Cedar Hills Blvd.
The traffic light defaults to green for Cedar Hills Blvd.
If there is no traffic on Cedar Hills Blvd I can get the light to change from about 200' away from the sensor. The camera sensor, which is mounted above the traffic lights on a pole, looks like a small CCTV security camera.

Steady light seems to be more reliable over flashing as does the intensity; this is why helmet mounting seems to be the ticket.

This is a great resource. Your post prompted me to submit my issue with the NB light on Aloclek crossing Evergreen Parkway. For those that aren't aware the Washington County roads service request form is at http://www.co.washington.or.us/LUT/D...st-service.cfm. I have had good luck with them responding to these requests.

I received an email saying they had forwarded my report to traffic engineering for a response.
