Traffic light stop sign combos

[Revive 755]

Are than any worse examples than this one on Octavia Blvd in San Francisco?

How do these work? Do you take your life in your hands when you pull away from a stop sign not knowing if cross traffic has a green light or not?

There is this one along PA 3 in West Chester, PA...

Does this in Richmond Hill, ON count as one:

Stop sign/signal combos, where one driveway or intersecting street meets within the signalized intersection, are prohibited in the 2009 MUTCD (not sure about the 2003 version).

I don't know how these situations would be handled from a technical standpoint. In all actuality, I would hope that most modern design standards would prohibit allowing a design that would make these situations necessary. Even though the traffic approaching from the stop sign is relatively minor, there are major safety concerns with having a street/access point within a major intersection. If absolutely necessary to design, prohibiting turns into the main intersection is definitely a good idea!)

Are than any worse examples than this one on Octavia Blvd in San Francisco?

This case is especially interesting, with a one-way "frontage lane" concept for a major street turned parkway. I like the fact that the on-street parking is separated from the through traffic, and that minor street intersections are confined to right in/right out along the frontage. Also, bicycles are encouraged to use the frontage lane. So it's an interesting design concept. However, the frontage lane meets major cross streets at a stop sign, and there appears to be the option of going straight or even turning into the major intersection. This seems like it would be an incredible safety concern.

Or this one on New Ballas Road in Creve Couer, MO:

What's immediately visible appears to be drive thru drop off for a post office, which stops at the main driveway for said post office. There appears to be another stop sign on the driveway at the signal...which makes no sense because the driveway appears to be signalized (signals facing the driveway are visible when rotating the Street View).

Does this in Richmond Hill, ON count as one:
[map link]

That appears to be a signalized pedestrian crossing that happens to also be at an intersection. This is another concerning design, as motorists on the side road or shopping center driveway may not realize there's pedestrian activity when the major road is stopped. This should probably be a full signal.

West Point Avenue @ Sullivan Road @ Old National Highway/S.R. 279

This intersection is at the northern end of Old National Highway, in College Park, Georgia.

Scofield Road @ Godby Road @ Godby Road Medical Center

Stone-Hogan Connector SW

The direction to the right, in the image, has no traffic light.

How do these work? Do you take your life in your hands when you pull away from a stop sign not knowing if cross traffic has a green light or not?

Pretty much (lol).

^^ Cool, but weird.

It simply looks like an old-style set of flashing red lights to me.

[Bryant5493]

^^ The stop signs one wire -- I've not seen stop signs mounted in that fashion before.

Here's one in southern St. Louis County, Missouri, with a driveway having a stop sign.  Though the driveway was there many years before the intersection was signalized, it doesn't look like it would be too hard to shift it away from the actual intersection.  There's also a car with an imperfect cloaking device behind the cam on Heintz Road.

A driveway without a stop sign, but still emptying into a complicated signalized intersection in Kirkwood, MO:

EDIT: No stop sign at this driveway entering a signalized intersection on 1st Avenue in Coralville, Iowa.  Would it have been that hard to add sensors and signal heads for the hotel driveway?

I have to wonder if that light is even warranted anymore, given the new one to the north that provides an alternate route to the area served by 7th Street.

At the convoluted intersection next to the pizza shop I used to work at, in the Observatory Hill section of the Northside in Pittsburgh, there is this:



Even without the road with the stop sign, this intersection sucks.  Mostly because of the topography there.  All the other roads (Baytree, East & Mairdale) intersecting Perrysville Ave (US-19) are coming up the hills on either side, so you can't see "past(?)" the intersection.
The road with the stop sign also functions as a primary exit from Perry Traditional Academy (Where all the buses queue and depart from and stuff like that).  It's also one-way there.

Another one from Romeoville, Illinois along IL-53:

There used to be another one north of here, but that one has since been cut off.

This should probably be a full signal.

Interestingly the Ontario Traffic Manual(OTM) still permits this type of signal setup although I also would like to see a full signal there. Here's  a page from the 2007 OTM showing a diagram of a similar setup (click to enlarge):

[roadman65]

Here is one that used to be that way and now seems to be more complicated. 

In Scotch Plains, NJ on US 22 at the Glenside Avenue- Mountain Avenue jughandle the jughandle that came in from Glenside Avenue into US 22 originally had NO signal heads whatsoever!  The other two jughandle ramps did have signal heads and those trying to cross US 22 from Glenside Avenue would wait for the other ramps to turn green to proceed cause those of you who are familiar with New Jersey are aware that US 22 has a high traffic volume in Union County.

Now signal heads were installed at all roadways, but now the Glenside Avenue jughandle and the US 22 WB jughanle to Mountain Avenue, both turn green simataneouslly.  Traffic from Glenside Avenue to US 22 EB have to cross those in the other jughandle driving straight across US 22 to Mountain Avenue.  Go to street view and see how this intersection is configured and you will wonder yourself how come an accident has not happened when two roads enter the same intersection from right angles to cross each others path.
