Title: Traffic Lights for Residential Driveways
Post by: Alex4897 on November 07, 2013, 08:08:13 PM
After going to Hershey Park a few times in the past two or three years, I noticed something that kind of surprised me.  There's a 3-way intersection in south Hershey where PA 743 switches streets.  However, instead of just signalling each of the three main intersection approaches, PaDOT (or whoever's in charge of it) hung two full blown signals and a "No Turn On Red" sign for a short driveway for a home alongside the road.

Anyone else have examples of this?

A veterinary clinic has signals for its driveway on Md. 214 (Central Avenue) at Pike Ridge Road in Edgewater, Anne Arundel County.

Google from above here (https://maps.google.com/maps?q=edgewater+md&ll=38.927448,-76.575665&spn=0.000514,0.000991&oe=utf-8&client=firefox-a&channel=np&hnear=Mayo,+Anne+Arundel,+Maryland&gl=us&t=h&z=20) and GSV here (https://maps.google.com/maps?q=edgewater+md&ll=38.927462,-76.575778&spn=0.000514,0.000991&oe=utf-8&client=firefox-a&channel=np&hnear=Mayo,+Anne+Arundel,+Maryland&gl=us&t=h&z=20&layer=c&cbll=38.927462,-76.575778&panoid=HWDDmHJ2JiHEQunS4c_KpA&cbp=12,96.31,,0,11.94).

Not the same situation, but this reminds me of an intersection near Granbury, TX, where there's a signal facing a short gravel drive leading to two gates accessing fields.  My guess is that it's related to permitted access points to the highway, but I've never seen any vehicles there or either gate open.  I also don't see any actuation equipment for that side.

I'd assume that was in preparation of an extension of that loop/bypass they're building, but it does look fairly useless at the time of the picture.

Long-term plans show a connection being built there, but the loop's almost 10 years old and it'll probably be 10 more years before the connection's built.  That's a long time to have a useless signal wasting electricity and bulbs.  I could see possibly building the structure in advance, but they shouldn't have it running showing a constant red for probably 20 years.

I noticed they had a left turn signal on the pole too, I highly doubt there's sensors tripping that.

There are at least two instances of this in the Birmingham metro area.  One is at the intersection of CR-95 and CR-44 in the suburb of Alabaster.  CR-95 dead ends into CR-44, and there is a driveway across CR-44.

The second instance is in the suburb of Homewood along Lakeshore Drive (SR-149).  In one direction, one turns into the entrance to Homewood High School (BTW, shameless plug: my nephew will be marching in the Tournament of Roses Parade on 1/1/14 with the Homewood band.  He plays tenor saxophone); at this same traffic light, one can turn in the other direction into a private driveway.

In Lakeside CA, at the jogged intersection of Los Coches Road, Lamplite Lane and Lakeview Ave, the Lamplite half is set up as a 4 way intersection with full signalization for a residential driveway on a ranch house.  Los Coches was widened around 2001 from a 2 lane country road and it appears that the driveway isnot even long enough for 1 car.

This is a 'Y' intersection.  The two driveways (1 each to the left & right) each have their own signal and doppler radar sensor. 

----------------------------------------------------------

http://goo.gl/maps/3f5y5
The driveway across the way has it's own light, a 'Do Not Enter' sign for wayward drivers, and even a short left turn lane for those needing to turn left into that driveway (I wish more normal intersections in NJ had left turn lanes!!!).

These two in Lafayette, IN are still there (https://www.aaroads.com/forum/index.php?topic=8878.msg206969;topicseen#msg206969)--the first is no longer on a state highway technically, although the INDOT-installed signals have been left behind.  There are loops in the concrete of the driveway/sidewalk (http://goo.gl/maps/AP7B4) of the house.

I've seen busy business driveways attach to a signalized intersection without any signal heads facing them.
There's one on I-20 in East Texas. It was kinda suprising to find this in Texas. The other one is in Chattanooga, TN. it wasn't so suprising to find this in TN- They seem to be clueless when it comes to traffic control issues.

PA seems to be notorious in signalizing driveways that are near/at intersections.  I guess it's easier than condemning the adjacent property or relocating dirveways.

Here's one not too far from where I live that was erected nearly a decade ago along Providence Road in Secane/Primos (Upper Darby Twp., Delaware County) at a shopping center entrance.  Note the 2 post-mounted signalheads facing the driveway (to the right).

http://goo.gl/maps/9oJLj (http://goo.gl/maps/9oJLj)

A signal-geek kid's dream come true if it were his driveway that was signalized.

Nonetheless, it still begs this question; why use 12" signalheads for the driveway (I can understand the reasoning behind using 2 signalheads) when 8" heads will more than do the job?

It's not like these signals need to be seen from a long distance nor the traffic volume along the driveway warrants such.

There is a sign that says "Private driveway, no thru traffic."  Your "Except Frank" reminds me of a Nissan commercial from around 1991, with "Bob's Expressway", "Bob" getting his own lane at the tollbooth, "Go Bob", "Yield to Bob", and finally "No Parking Except for Bob."  A policeman is about to write a ticket when he realizes, "Oh, it's you, Bob."

Most of those driveway traffic light situations look like ideal places for Walgreens and CVS stores.

VERY VERY odd they haven't built them yet.

If pans 90 to 135 degrees the the left of the example I posted, one will see a CVS in the shopping center itself (not the driveway).

While the shopping center was there for decades the signals and the CVS came around the same time.  This CVS moved from its previous (& smaller building size) location at the Providence Plaza located further up the road.

Suder Avenue - just south of Ottawa River Road.  Light was put in when Kroger was built a few years ago.

On the topic - are the traffic signals serving such driveways turned off at night or dimmed?  One would think it would be a distraction to have three colors beaming into your living room or your bedroom at night.

I'd think that the considerate thing to do would be to have one 8" signal instead of two full blown 12" ones.

There aren't loop detectors on those driveways, I don't think. I've driven by that hundreds of times, as I used to live in Crystal Lake. I never gave it a second thought. I've got to be out there next week, so I can drive by and take a closer look.

Though looking at it on Google maps, that is strange.

AASHTO requires the 2 signals though, even if it faces a residential driveway, though 8" lenses would be allowed in this case as it is well below the speed threshold.  But the usual case is for a residential driveway in the intersection not to have a signal facing it.

The 2 intersections in GA I mentioned, both have loop detectors in the driveway and the second has another way out without the signal:

There are at least two examples I know of in the Springfield, MA area.

One is at Converse St and Dickinson Rd in Longmeadow, MA.  There are two driveways to the left, each getting its own 3M high visibility signal to control.  One is on the near side of the intersection, the other on the far side.
https://maps.google.com/?ll=42.067885,-72.554162&spn=0.011246,0.022724&t=m&z=16&layer=c&cbll=42.066269,-72.555291&panoid=NFLEtJitl14X-fojEh9JOA&cbp=12,278.99,,0,0

The other one is Parker St at Nantasket St in Springfield.  There is a traffic light on the right side of the intersection for the driveway on the left.  While there is a detector for the driveway, it frequently doesn't work properly and causes traffic to wait through the cycle of the driveway with no one there.

3 things to look at in that GSV:

A) The side street is called 'No Name Street'.  It leads to a shopping center (and a street named Shoppers Ln).

B) A single traffic light appears to face the driveway.  I couldn't see anything that would activate the light, so it may simply be activated only when traffic from 'No Name St' activates the light.

C) The 3 workers watching the Google Street Camera vehicle drive by.

The opposite problem (and a business driveway at that) - http://goo.gl/maps/4Ilei - The driveway to the right lead directly into the intersection, but the traffic lights did not face that driveway, and anyone trying to come out was on their own.  Ultimately, the construction you see in that GSV eventually fixed that problem.

Suder Avenue - just south of Ottawa River Road.  Light was put in when Kroger was built a few years ago.

On the topic - are the traffic signals serving such driveways turned off at night or dimmed?  One would think it would be a distraction to have three colors beaming into your living room or your bedroom at night.

I hope that's just a traffic camera and not a red-light enforcement camera mounted on the mast-arm of the driveway signals lol.

High mounted small cameras like that are always optical traffic detectors used to trigger the light. Red light cameras are always big boxes mounted low enough to get a good image of the license plate and sometimes the driver's face.

And an "ALL TRAFFIC MUST TURN LEFT" sign on the mast arm. Must be fun for this guy trying to get home. Unless they had a white-on-black supplemental plate underneath that said "EXCEPT FRANK".

Wow! I count 6 signal heads facing the driveways, including left turn arrows, if I'm interpreting right.

I'm betting the OP had no idea that there would be so many examples of residential driveway signals. I know I didn't. Now that I've seen all these uses, I can easily imagine why it's done. For many of them, a new road or shopping center entrance is put in opposite the existing driveway or an existing road now warrants a signal due to increased traffic. It is more economical to erect and maintain the extra signal heads than to buy out the home owner.

As with a few other instances, they made it a split phase timing so if the driveway gets a green, they are the ones getting the green.

In lieu of a full-blown red/yellow/green signal, I've seen this alternative (http://goo.gl/maps/kBceZ) a few times in Michigan.

The driveway has one red signal head. When cross traffic has a green light, the driveway has a solid red. When opposing traffic has a green ball (never seen arrows with this setup), the driveway turns to flashing red, like a stop sign. It's not something I'd trust - not everyone reacts predictably, you can't tell when the flashing red cycle will end, and you're screwed if the signal burns out.

One example I know of is in Plymouth, MN, where CSAH 6 meets MN 55.  Here's the Google Street View (https://maps.google.com/?ll=44.999329,-93.441027&spn=0.001644,0.00284&t=k&z=19&layer=c&cbll=44.99924,-93.44147&panoid=Tns1kpFBT49k3Vr7GaSOHw&cbp=12,326.47,,0,3.16) from westbound MN 55.

The house has been there for decades, since before MN 55 was rerouted/reconstructed along what was then an old county road and long before CSAH 6 was rerouted to meet MN 55 here.  Since MnDOT has long used overhead vehicle detectors for signals (usually mounted on the mast arm), there are no issues with "repairing pavement detectors".

When a signal was installed at the T-intersection of E Payton Ave and Indianola Ave in Des Moines, as part of the widening of Indianola Ave, the folks at the back of the intersection got their own signal. This picture shows their driveway–I don't have a picture facing the other way, from their perspective. This picture was taken before construction was completed and the signal turned on.

From the street view you can see that the driveway has two lights with a left turn arrow light (don't know what that light is called) and has a left turn lane for the driveway on northbound Route 50 with a doghouse for the left turn into the driveway. Plus the Target road has a left and straight turn lane.

https://goo.gl/maps/8yqdhLLRcES2

What this thread brings up, especially the above link, is the issue of signal detection at the driveway leg of the intersection.  Obviously, this leg of the intersection will have very few cars at each cycle and should not be triggered at every light cycle.  So there should be a way of only triggering this when the resident wants to pull out.

One approach would be to provide signal detection, even though it may be costly.

A second approach is to always provide a green when opposing traffic has a green.  For the odd circumstance where the resident wants to proceed and nobody is coming from the opposite side - he'll just have to wait or make a right turn.

A third approach is to provide that the signal changes  on a timer and stop main street traffic regularly, even though the driveway gets little use.

For the above singal to work - the provision of its own exclusive phase, exclusive of opposing traffic, there would need to be signal detection, otherwise it is very inefficient.

Hasn't signal detection been normal since the 1970's? I'd be very surprised if the driveway wasn't activated by detection already.

Didn't notice you said this until I re-read the thread, but no it's not the only one. This one in Northbrook, IL has three signals facing one driveway, all displaying a protected left for the driveway.

This is an interesting old thread to see resurrected.  Here is one that I have not seen mentioned yet, at Cowell Road and Coventry Road in Concord, CA:

Protected left turn INTO a private home's driveway.  That same driveway also has signals for when they exit.

Interestingly enough, this signal was installed by Cook County I believe within the last 15 years or so. Used to just be a three-way (or four-way, I guess) stop. Either way, as a kid I always was so excited when I saw a car waiting to leave the driveway, and I would ride my bike up to the light just to see it change. From then 'til today, I've still probably only seen it a couple dozen times.

Just found this one in Schenectady, New York on Google Street View at the intersection with Target & Saratoga Road (NY Route 50)

From the street view you can see that the driveway has two lights with a left turn arrow light (don't know what that light is called) and has a left turn lane for the driveway on northbound Route 50 with a doghouse for the left turn into the driveway. Plus the Target road has a left and straight turn lane.

https://goo.gl/maps/8yqdhLLRcES2
Yes, it appears their is a detector on the pole nearest to the house.

What this thread brings up, especially the above link, is the issue of signal detection at the driveway leg of the intersection.  Obviously, this leg of the intersection will have very few cars at each cycle and should not be triggered at every light cycle.  So there should be a way of only triggering this when the resident wants to pull out.

One approach would be to provide signal detection, even though it may be costly.

A second approach is to always provide a green when opposing traffic has a green.  For the odd circumstance where the resident wants to proceed and nobody is coming from the opposite side - he'll just have to wait or make a right turn.

A third approach is to provide that the signal changes  on a timer and stop main street traffic regularly, even though the driveway gets little use.

For the above singal to work - the provision of its own exclusive phase, exclusive of opposing traffic, there would need to be signal detection, otherwise it is very inefficient.

Hasn't signal detection been normal since the 1970's? I'd be very surprised if the driveway wasn't activated by detection already.

Suder Avenue - just south of Ottawa River Road.  Light was put in when Kroger was built a few years ago.

On the topic - are the traffic signals serving such driveways turned off at night or dimmed?  One would think it would be a distraction to have three colors beaming into your living room or your bedroom at night.


Someone else bumped it, but I feel compelled to reply to this anyways.

This example in Bothell has a 3M visor. 

I've driven by it at night, and it's very dim.  Interestingly enough, on SV, you can see that the luminaire has a shield, the yellow signal border is peeling off of one of the mainline signals, and one of the pedestrian signals is knocked off.

I found a driveway in Virginia that is all but signalized (https://www.google.com/maps/@38.72916,-77.7191197,3a,75y,127.68h,87.67t/data=!3m6!1e1!3m4!1s5gFBVXWffjkOuy5YR-Yz5Q!2e0!7i16384!8i8192/)--gantries, two-section beacons, signs, the works.

Honestly, what a waste. To put up a whole extra gantry for a private driveway is just disrespectful of public funds.

Heh. At least public funds got used here. You would be amazed at the waste of funds that don't result in anything being done.

Why is one of the pairs of flashing yellows horizontal while all the other signals are vertical at that intersection (including the yellow the other way)?  Weird.

The is a weird intersection in total because it's tied to a branch-off 100 feet away. But for this thread: The main road, Kings Hwy, generally has 8" signal heads. The driveway off to the left gets 12" signal heads.

A similar topic, probably not worthy of its own discussion, is what I call private lanes.  These are lanes on public roads that serve only one or a few homes.  I know of two examples.  This one is in Hillsboro, Texas along the I-35 frontage road.  Southbound traffic moves from a two-way road to a one-way road.  Northbound traffic originates only from the driveway (or any U-turns that happen here).  Further north are a few more homes.  The first public road intersection to the north is a county road about 3/4 mile back.

The construction plans call for a similar lane configuration along the business route of the recently opened Cresson bypass on US 377, but it has not been Street Viewed yet.

That's interesting.  A road near me has been rebuilt and had multiple one-lane two-way sections for a few years.  The practice seems to be putting the controlling signals far enough apart so that you can't see one end from the other end.  When a bridge is down to one lane, they put the signals on the other side of the hill at the top of the valley, resulting in a long one-lane section.  This results in private drives and public roads intersecting the one-lane section.  Someone who's unwilling to wait can just go around the signal with no real problem.  Since the whole stretch, minus the bridge, has two lanes with one blocked by barrels, they can just pull over to the closed lane if anyone is going the other direction.

This practice bothers me.  To clarify, I'm referring to a rural road with light traffic.  If they put a signal on each end of the bridge, people would see that no one is approaching from the other side and just ignore the signal and go through.  To prevent this, they have a mile-long one-lane stretch around a 50-foot long bridge, so you can't see if anyone is approaching from the signal location.  This results in longer waiting on a road on which about 70% of the time there isn't any traffic during passing through a green phase, even with the long span.  I stop, of course, but I still think unpleasant things about the people who planned this.  If this were a busy road where there's never a break in traffic it would be different, but I really think that if there's little traffic you could just put yield signs on the side where the lane closes and maybe a warning sign on the other side and trust people not to drive like suicidal maniacs (who have the patience to wait for opposing traffic to approach).

I've turned from one of the county roads onto the one-lane stretch.  There's no signal, but I had no worry because I could easily go to the closed lane at any point other than the short stretch where there's actually no other lane.  In places where there's traffic and only one lane, the signals at homes would be helpful.

This driveway for a church, pictured here before the signal was replaced with a new one, now has a signal facing it.

Due to the nature of 4-way signals, this house in Oxford, AL, has a pair of signals facing its driveway:

Signals facing the driveway aren't all that unusual. The stupid use of "2 Way" Stop signs at a signalized railroad crossing is though.
