Is FYA or FRA allowed for right turns?

This is a question I was curious about, is there anyone who uses flashing red or yellow arrows for right turns....I know a few places where such a situation would be very convenient.

So I was wondering if anyone knows if they are used anywhere, or if they are even allowed.

Right-facing FYAs have begun showing up on a limited basis. Some areas seem to use them more than others. There are none anywhere near me; the first one that comes to mind is the NB 15 Fwy off-ramp towards the Timpanogos Hwy (EB), south of Salt Lake City. I believe it goes red only when pedestrians activate the crosswalk.

Frankly, I'd place right-facing FYAs at the end of all channelized right turns, but that's rather expensive.

Interesting....anyways if you want to know, this is a situation I propose that uses both FYA and FRA for right turns:

Yes, I'm using another Brampton example, this time Kensington and Central Park, in the Bramalea City Centre vicinity:

https://goo.gl/maps/d9wTwCTVnKQ2

In this situation, ALL right turns on red are prohibited because of a potential conflict involving the transit signal. The transit signal when it gets its green has its movement entirely protected, everything else in the intersection faces a red.

Below is how I envision signalling this intersection to eliminate the restriction, in this intersection, only EB to NB Kensington to Central Park left turn has any form of protection.


































Central Park Dr NB-SB Main||Kensington Rd WB Left Signal        Kensington Rd WB Main Signal        Kensington Rd WB Right Signal        ||Transit Signal
Red Ball||Red BallFLASHING Red Arrow||Red Ball

And then repeat again....if there is no bus waiting at the transit signal stop line, then the transit signal phase shall be skipped.

NYC has been installing them at more places in the past few years. Mostly 3 section signals to give pedestrians a headstart on crossing.

Example

Queens Blvd/Thompson Ave and Van Dam St, Queens

Ace10

I've seen two of these in Oregon - they're both FYA right turn signals. One is at the intersection of NW 3rd St and NW Van Buren Ave in Corvallis where drivers travelling on Oregon Route 34 turn right to remain on OR 34.

I think another one of these has (or is about to) pop up along Cornelius Pass Rd in Hillsboro between Cornell Rd and US Route 26. It's a four-headed signal on the right corner of the intersection, so what else could it be? There's been lots of road work in this area the past few months, and it looks like a new multi-use path is opening just immediately to the east of Cornelius Pass Rd (which runs north-south). I bet the new signal will have a red arrow when trail users need to cross the cross street, and will otherwise be green or flashing yellow.

Revive 755

Flashing yellow arrows are shown quite a bit in the US MUTCD as an option for right turns.  As for places I've seen FYA's for right turns:

* A couple locations in Madison, WI

* SB Big Bend Road at MO 100/Machester around St. Louis (Streetview

* A couple corners around Lincoln, Nebraska



IMHO using a FYA for a right turn ought to be looked into if there is a separate right turn lane, a crosswalk parallel to the right turn lane, and a leading ped phase is desired, and maybe in cases with dual right turn lanes opposed by a permissive left turn movement.

I made a video several months ago about a T-junction near me that uses only flashing yellow arrows:

Last October, we were heading west from Austin TX on U.S. 290 when we saw a right turn FYA at an intersection, William Cannon Drive, that has continuous flow left turn lanes. I didn't have time to analyze the intersection, but it seems logical that a right turn off of U.S. 290 creates a conflict with traffic in the continuous flow left turn lane that is turning onto the cross street at the same time that 290 traffic has a through traffic indication. Thus, there was the flashing yellow right turn arrow to warn of the potential conflict. (Not sure whether the right turn traffic has a merge lane to minimize the conflict).

EDIT: To follow up, Google Maps has the intersection on satellite view, and the left turning traffic from the CFL lane is in a single lane directed to the left lane of the cross street. Right turn traffic from the opposite direction is OK if it turns into the right lane.

Is that protected right turn REALLY necessary? I don't see hordes of pedestrians waiting to cross.....

Since it's a RED right arrow, are right turns fully prohibited on that phase?

Fully protected right turn signals are relatively rare in Ontario, I can only think of a few off the top of my head, but in all those cases, there is a "No Right Turn on Red" sign that goes with the signal, I see no such signal here, are turns allowed on red arrow?

If I had a dollar for every time I had to sit behind someone that stops at one of those even though the lane continues past the intersection, I'd be a rich man.

I want to say there is at least one signal of this type in Tucson, near the downtown area.

A right turn against a red arrow is permitted in Washington State. The only time a red arrow shows is when the cross street has a green. If the pedestrian light is activated, it flashes yellow. In other words, it's not a protected turn.

Is there a lot of pedestrians? No. But this is a new standard for the city of Federal Way. All T intersections will now have left and right facing FYAs.

Regarding the bolded statement: If the green arrow is on, then no other conflicting movements are going simultaneously–in this scenario, it is protected. The right turn signal is basically protected/permitted (the mode being determined by the presence of pedestrians).

Federal Way's policy here is actually a decent one, but only if it is desired/necessary to have pedestrian crossings to both sides of the "T" stem–one FYA can be eliminated if the adjacent ped crossing is removed.

Sorry. When I said it wasn't protected, what I meant was that you can turn on red (SG1 brought up prohibited turns, so that's where my mind was).

They could do that, but I fail to see the reason why. It doesn't really hurt having it on both sides.

It would basically come down to a capacity issue.

For example, one scenario would remove the crosswalk conflicting with the left turn coming from the stem, to in essence always have a protected left turn. Since the right turn on red is usually allowed, more signal time for the stem leg is needed to clear left turns as opposed to right turns. Eliminating the crosswalk across the left turn allows more time to clear that lane between cycles. This is a typical setup in Nevada–and is nearly always implemented if it's a dual left turn, since Nevada very rarely allows dual permitted left turn scenarios.

Also the right turn lane will get a protected signal during the cross streets left turn even if it missed it during the crossing phase. In this scenario, the left turn seemingly could end up never getting a protected phase if the crosswalk is getting used continuously.

NYSDOT Region 4 has them in Geneva. In this case, the right turn in one direction immediately crosses a rail line, so this allows the right turn to be independent of the straight movement.

Couldn't Region 4 achieve the same result using a 3-head signal? I'm all for using FYA's at right turns, particularly when there's a crosswalk involved. But I can't think of a use for it here, lest there's a crosswalk?

It's 3 head (no green) and NTOR because of the railroad tracks.

Gotcha. So the standard phase is flashing yellow?

Correct. Here is the intersection in GSV. To the south (left) is a park with little traffic, so right turn traffic will rarely face a red arrow unless there is a train.

Very cool! So it acts more like a slip lane with a yield sign? Does it go red when EB traffic has a green arrow?

I don't remember. Generally, New York's FYAs flash when opposing traffic is green even if the adjacent through movement is red, so it is possible that it doesn't. Region 4 has been quite aggressive and inventive with their FYAs and I'd love to see stuff like this throughout the state where a grade crossing is next to an intersection.

Maybe it's just me, but I'm VEHEMENTLY against a red right arrow meaning that one can make the turn if they stop. If that's what they intend the right arrow to mean, then they should use a red ball.....since arrows are the way of the future, make it a flashing red right arrow, thus it has the same meaning as we assume with a flashing red ball.

The whole concept of giving a left and right PROTECTED phase has me still scratching my head when there are very few pedestrians here. Instead, why couldn't they use this approach with the sequence:

FLASHING Right Red Arrow (Displayed when cross traffic has the green)
FLASHING Yellow Arrow (Displayed when this T intersection has the "green")
SOLID Yellow Arrow
FLASHING Right Red Arrow

I honestly think the green right arrow phase is totally unnecessary, it would only make sense if there were a serious flux of pedestrians, but it looks like this intersection in suburbia sees very little action pedestrian wise, so really, what's the point?
