Hazardous Obstacles on the Sunset MUP
Back in Feb, I was riding on the Hwy 26 MUP between Portland and Beaverton, when I noticed that the Worst Day of the Year Ride's route had been marked along my commute route. However, no effort was made to identify three hazardous street lamp bases that jut into the MUP. It seems that whenever I ride through there, it's inevitable that someone will be walking, or cycling against me, so I need to keep to the right as I'm cruising downhill. It got me thinking...
2000 riders, going past these things 2 or 3 abreast, and we've got an accident waiting to happen.
I brought this to ODOT, but they didn't do anything. I also informed the ride's planners, and they could only temporarily mark the street lamps. Not long afterwards, the markings were taken down, or wore off. So, back in June, I applied some reflective tape to the lampposts, and I tried painting the bases with pavement marking paint (I also superglued some reflectors to it, but they aren't holding up).
The paint faded... (continued in pt 2)
Hazardous Obstacles on the Sunset MUP
Continued from pt 1
The paint faded...
So, I obtained some self-adhesive, foil backed, reflective lane marking tape...
I used up all that I had (only was able to do two of the three, but I got the worst of them).
Let's see how it holds up. My next idea is to use some of the reflective glass microbeads that I have scooped up over the years, mix it with some AB Urethane casting material and pigment, and pour that over the things if ODOT doesn't do something soon.
Can we get a permanent solution to this installed? Perhaps something like this?
It's a 4" wide thermoplastic stripe that warns cyclists of the hazard ahead.

Q: Back up on the Hwy 26 MUP
Any idea how your fixes are being removed?
Who built this path and who is ultimately responsible for its maintenance?
Is this responsible party different from the party responsible for the obstructing light poles themselves?
I find myself wondering if there isn't some bureaucratic turf battle over what is allowed to be done to fix this.
As a geek I've got a current copy of the MUTCD and have full sized and situationally scaled templates of the mandated signage that would be required by law if these light pole bases protruded in to a "real" road. The fixes I have pondered would be scale and speed appropriate for this MUP environment. There area many useful engineering equations in the MUTCD.
I "found" some unused pieces of Corex on roadsides that I intended to use as the sign board. Signs would be similar to Section 2C.64 Object Markers for Obstructions.
I recovered the composite spring loaded spars from some trashed pop-up safety cone "Wet Floor" signs. The idea being that the spring portion would be at the base so when someone came by and hit the sign it would give way.
Looking in the workplace safety catalogs I figured out how to mount the sign bases to concrete such that it would take a hammer and chisel to remove the base. Even tested a way to keep the steel spring flexible but protected from weather and rusting.
I've got this idea about "painting" road markings (per Section 3B.10 Approach Markings for Obstructions) for the obstructions. In this case "painting" would involve abrading a strip of the concrete where I would embed a thin layer of retro reflective beads in white tinted epoxy. If done right the epoxy and reflective material would be embedded in the surface still being visible but allowing traction: like chewing gum.
All this planning is for naught if someone is removing these things.
Fixes being removed? Or just wearing off?
The paint just simply faded. To get the adhesive of the foil lane markings to stick, I decided to scrub the bases with a wire brush. I don't know how effective this will be, as it is a "temporary" lane marking and I'm out of CA glue to try to seal the edges.
ODOT is the party responsible for the construction and maintenance of the MUP, but for some reason, that I can't figure out, they don't see the risk. I doubt that there's a concerted effort to counter my attempts to improve the visibility on their part.
As to the options posed by you, I'm going to have to investigate, as I'm not entirely familiar with some of them.
I've sent another one of my shotgun emails to several agencies, members of the press, and injury attorneys. I doubt that this can be now be blown off as easily, now that 15 pairs of eyes (not including forum members) are now focused on the issue. [/EDIT]
Ooh, Ahh... The Language of Traffic Engineers...
Thanks for doing your homework q`Tzal!
I'm going to use this in my next email...
Oh wait a few hours
I'll have some cruddy CGI mockups.
Maybe ODOT is misjudging the downhill speed there if they don't seem to think its an issue. Its not such a big issue if that was the uphill side, but that is a really fast section going westward, and it feels very narrow at those posts if there is any oncoming traffic.
It would look something like this as a minimum:
A whole hog implementation, how I think an equivalent obstruction (~ 3'-4' ) might be handled on TV Hwy, would look something like this:
Of course I think that the DOT responsible should be doing this but it seems that designating anything as an official bikeway comes with the assumption that it needs NO further official enhancement other than pavement.
I'm no engineer but what I've plotted out seems in spec and something ought to be done.
New night photos, and my vote...
Went out there with more paint (Rust-Oleum Professional Traffic Striping Paint), some reflective film (the yellow stripes), a (found) cat-eye reflector, and some glass microbeads to try to improve the visibility of this trail-side hazard.
Photo was taken with a helmet mounted light source, not a flash (camera's is burned out). Even with the improvements, it's still not demonstrating the hazard to cyclists well enough.
In looking over this... I think you missed something, this is a raised obstruction, so the math should be L = (W+1) S. As for the "S" I've been known to approach 40mph on this decent
Oh! You spotted something I missed... That sudden edge on the left. The streets are below the height of the path, and it just drops off, no warning.
Thanks for the images q'Tzal!
While researching for those images I noticed that I had not read through the entire bicycle section, only pieces.
I am doing so and noticed the equation as well. You failed to take in to account one thing about my draft images: your photos have no scale. ;)
I could not reasonably have made anything other than an approximation.
I was tempted to take my 100' tape measure out to get a propper engineering plot until I remembered that PortlandMaps.org will most likely have all the details plotted out in their maps database.
Also: with all this traffic sign wonkery shouldn't we relocate this line of conversation to an "All about West side" thread?
