Title: Intersections With Two or More Seperate Straight Movements - Same Direction
Post by: Brian556 on June 16, 2014, 11:12:29 PM
I found two of these in Orlando, Florida.

One is at John Young Parkway and Greenwald Way.
https://maps.google.com/?ll=28.346771,-81.419432&spn=0.006657,0.012392&t=h&z=17 (https://maps.google.com/?ll=28.346771,-81.419432&spn=0.006657,0.012392&t=h&z=17)

The other is Garland and Amelia in Downtown Orlando. It actually has three separate straight movements- Garland Ave, I-4 exit ramp onto Garland Ave, Bus Lane.

These seems very dangerous to me.

Reason #1: If somebody does not see the NO TURN ON RED sign, it would cause a serios accident. This could very easily happen, especially at he John Young Parkway example because the NO TURN ON RED sign is only on the mast arm, which is a long way from the stop bar. In my opinion they should defiantly put a second NO TURN ON RED sign on the close side of the intersection, on the island, with metal orange flags. Also, there should be a custom warning sign in advance of this situation.

Reason #2: Signal Power Failure-this situation would make this intersection impossible to navigate safely--I certainly hope they have a backup generator here.

Are these common anywhere else? I'm glad they don't do this in Texas.

We have some of these in New Jersey.  Two a short distance from each other in Jersey City, in fact.

1) Bottom of exit ramp for Columbus Drive from the Turnpike Extension (I-78 East):
https://www.google.com/maps?ll=40.720602,-74.05452&spn=0.000004,0.00327&t=m&z=19&layer=c&cbll=40.720381,-74.055106&panoid=iqwwjEHK3WDbO1V-sr_qJA&cbp=12,356.88,,0,6.3 (https://www.google.com/maps?ll=40.720602,-74.05452&spn=0.000004,0.00327&t=m&z=19&layer=c&cbll=40.720381,-74.055106&panoid=iqwwjEHK3WDbO1V-sr_qJA&cbp=12,356.88,,0,6.3)

2) The very next (and last) exit from the Turnpike Extension where the freeway ends at the first of a handful of signals before I-78 East ends at the Holland Tunnel toll booths:
https://www.google.com/maps?ll=40.730632,-74.045549&spn=0.000003,0.001635&t=h&z=20&layer=c&cbll=40.730632,-74.045549&panoid=s7uheOTp2AUJ-Q8C7e9l7Q&cbp=12,103.27,,0,0 (https://www.google.com/maps?ll=40.730632,-74.045549&spn=0.000003,0.001635&t=h&z=20&layer=c&cbll=40.730632,-74.045549&panoid=s7uheOTp2AUJ-Q8C7e9l7Q&cbp=12,103.27,,0,0)

Both are signed for No Turn on Red.  The first signal does not allow turns across the adjacent parallel roadway, even on green, while the second signal does.

Couple of this variety along Palatine Road in Chicagoland:
Palatine Road at Windsor Drive (https://www.google.com/maps?q=Arlington+Heights,+IL&hl=en&ll=42.110055,-87.965754&spn=0.000866,0.002064&sll=37.09024,-95.712891&sspn=59.597077,135.263672&oq=arling&hnear=Arlington+Heights,+Cook+County,+Illinois&t=h&z=20)

Palatine Road at Schoenbeck Road (https://www.google.com/maps?q=Arlington+Heights,+IL&hl=en&ll=42.109917,-87.946368&spn=0.000866,0.002064&sll=37.09024,-95.712891&sspn=59.597077,135.263672&oq=arling&hnear=Arlington+Heights,+Cook+County,+Illinois&t=h&z=20)

Palatine Road at Wheeling Road (https://www.google.com/maps?q=Arlington+Heights,+IL&hl=en&ll=42.109796,-87.927096&spn=0.000866,0.002064&sll=37.09024,-95.712891&sspn=59.597077,135.263672&oq=arling&hnear=Arlington+Heights,+Cook+County,+Illinois&t=h&z=20)

At all three the frontage roads have an exclusive phase; the sequence is along the lines of Palatine Road main lanes>EB frontage road>WB frontage road>side road


Also in Chicagoland are a couple along IL 64:
IL 64 at Cornell Avenue/35th Avenue (https://www.google.com/maps?q=Arlington+Heights,+IL&hl=en&ll=41.907587,-87.87598&spn=0.001745,0.004128&sll=37.09024,-95.712891&sspn=59.597077,135.263672&oq=arling&hnear=Arlington+Heights,+Cook+County,+Illinois&t=h&z=19)

IL 64 at Hawthorne Avenue (https://www.google.com/maps?q=Arlington+Heights,+IL&hl=en&ll=41.907815,-87.871549&spn=0.001745,0.004128&sll=37.09024,-95.712891&sspn=59.597077,135.263672&oq=arling&hnear=Arlington+Heights,+Cook+County,+Illinois&t=h&z=19)


Depending upon where the line is being drawn between straight and 'slight shift/double turn' MO 100 at Kingshighway in St. Louis could count, but I cannot verify through streetview if the straight/shift movements from the outer roads are allowed. Google Aerial (https://www.google.com/maps?q=st.+louis,+mo&hl=en&ll=38.625861,-90.264652&spn=0.001295,0.002064&sll=41.905854,-87.861013&sspn=0.05583,0.132093&hnear=St+Louis,+Missouri&t=h&z=20)

Might also be able to count Kingshigway at McRee in St. Louis.  The SB movement has a no left turn sign, but does it really prohibit going straight?  And to make it more fun, the intersection has red light cameras.  Google Aerial (https://www.google.com/maps?q=st.+louis,+mo&hl=en&ll=38.620638,-90.26593&spn=0.001295,0.002064&sll=41.905854,-87.861013&sspn=0.05583,0.132093&hnear=St+Louis,+Missouri&t=h&z=20)

CT has one, I-95NB Exit 8 ramp.

https://www.google.com/maps/place/Atlantic+St/@41.0479691,-73.5395067,73m/data=!3m1!1e3!4m2!3m1!1s0x89c2a1e182783869:0x40bb1941220c8397

The ramp side turns green first, then the frontage road part at the same time as the ramp.  You hope everyone stays in their lane...or the one you think you should go in.

Ramp is NTOR.

This will be  replaced as there are plans to redo this intersection

Roosevelt Boulevard (US 1) in Philadelphia has most of its intersections with this configuration, with inner "express" lanes allowing left turns at signals and the outer "local" lanes allowing right turns.  There are numerous cross-overs, and a few spots where the express lanes go under major intersections.

Here's a typical intersection, but the traffic volume shown doesn't do it justice for rush hours.  I've never seen traffic so light on the Boulevard.

Interesting that left turns are allowed from the side lanes. There's actually no need for that movement because traffic coming from the SPUI ramp could take the Greenwald/Thacker intersections off Osceola Pkwy and probably arrive at the destination sooner.

Here's one in Wilmington DE.  This is just off of Exit 6 on I-95 southbound at the intersection of 4th and Jackson.
