Default New signal

I just noticed this news story in the Tribune:

"State pushes up pedestrian crossing signal for dangerous TV Highway intersection

The Oregon Transportation Commission agreed Thursday to speed up installation of a pedestrian traffic signal at the intersection of Southwest 178th Avenue and the Tualatin Valley Highway in Aloha."

http://www.portlandtribune.com/news/...medium=twitter

I'm wondering if anyone is familiar w/ that intersection from a bike perspective. If so, how/if this signal might impact bike safety.

The not presently in print Washington County Visitors Association bike map shows TV Highway having a full 4' bike lane through that section of the highway(the Bike There! map shows it too).

Unfortunately, TV highway is one fast, dirty, nasty highway to ride alongside, even with a clearly marked 4' wide bike lane. For that reason, I avoid it if at all possible. At least part of a commute route can be made on quiet neighborhood streets Alexander and Johnson on the north side of the highway starting at 170th, and Blanton on the south side. They don't have bike lanes, but traffic on them is low and slow enough to support good biking on them. From previous threads here in the forums, I recall other people commenting that they use those streets. They're some of the ones I prefer if I'm traveling between Beaverton and Hillsboro, etc.

Pedestrians really need a crosswalk signal that stops motor vehicle traffic with a red light at 178th, so pedestrians can cross safely; It's 3/4 of a mile between 170th and 185th, presently the nearest intersections to 178th with such a light. From 178th in either direction, that would be about 1800 feet...same as 9 blocks in downtown Portland. That's a lot of hoofin' it to cross the street safely on a regular basis.

What? Not a single other person besides myself from the West Side or parts beyond has any personal experience to relate about this section of TV Highway with its few safe crosswalks? I know there are people that ride this area regularly, and that are probably checking in on this forum from time to time.

Why are you not taking advantage of the opportunity this thread offers, to let people that check it out, have some first hand accounts of where infrastructure in this area could benefit from improvements?

Default TV Hwy Crossing

As an instructor for the League of American Bicyclists, I work with several group homes that adults with physical or mental challenges live. There is a house near that crossing that I have been working with staff to get residents to be able to get to the 7-11 on the north side of the highway on their own. “Dennis (one of the residents) loves his coffee!”

In itself, my assessment is that this cannot be done without staff present.

ODOT has tried to take steps necessary to reduce collisions between cars and pedestrians, but all, so far have been incpmplete.

Without a light at that crossing, it is nearly impossible to cross without at least one of the 4 lanes having a vehicle that doesn’t stop.

As for bicycle traffic, it has been pointed out that TV hwy is a miserable place to ride. I agree, but for a straight line shot east-west, there is little alternative.

The WashCo BTC has been striving for 12 years to improve conditions for bicycling in Washington County and we're making bigger steps now than in the past.

We look forward to the West Side Get together on the 27th to share and collaborate on ideas.

Default New signal

I live within a mile or two of this crossing. From what I have seen its mainly used by Tri-met riders accessing the bus stops on either side of TVHWY. For people on bikes crossing going north it dumps them in a heavily travel residential area that is used as a cut through for those avoiding backups on TVHWY.

Yosh...welcome to the forum, (your first post....excellent )and thanks for your observations on the crosswalk at 178th, as well as on motor vehicle use of streets in the residential area north of TV highway at this intersection. I'm presuming you're referring to Alexander. In an earlier comment, I described this street as being located in a quiet neighborhood...which I'm inclined to think it mostly still is...but to be accurate, it's been awhile since I've actually ridden it. I wouldn't at all be surprised if it's being heavily used by motor vehicles as a cut-through to escape traffic congestion on TV highway during, for example, rush hour.

Other than those hours, I'm thinking it's still probably a mostly slower traffic, quiet street. That's partly because it's rather narrow and has some ups and downs that don't allow a long sight-line for people driving cars. I'll get over and check it out before long.

This should be an excellent street for bike travel if cut-throughs haven't made it otherwise. If one were there, for many types of people riding bikes and wanting to cross to the south side of the highway, a signaled crosswalk at 178th may turn out to be far more preferable for crossing than with the intensely busy traffic on 170th, either on the road itself or in the signaled crosswalk there.
