@@trafficsignalstraining7673 Yup, though I assumed LPIs were pretty easy to set up with the “delayed green” function, so for some reason I assumed the same for Leading Bicycle intervals as well. Slightly off topic, but I’d love to see a video about blank out (part time restriction) signs and how they work in a controller. I’m starting to consider them more with exclusive pedestrian phases and at other signals.
@@Petru.S I have one video, although it just shows the blankout sign in action. it doesn't show the controller side, but we are driving it with an overlap green that serves when a specific crosswalk is active. Here it is... th-cam.com/video/dVVOj0oVfWo/w-d-xo.html
Very cool! We don’t have any transit corridors on the intersections I maintain but I’ll have to go over some of the many logic statements I’ve implemented at our more complex intersections! Great video as always!
The flashing triangle interval isn't required per the MUTCD...or at least it allows you to use some engineering judgement. I read that and we determined we were not going to flash the triangle...seemed like a massive headache.
@Traffic Signals Training technically, this is for light rail. I think we found examples of other cities using solid triangle. But I'd have to look through my notes and our justification document. IMO, I'm not sure what a flashing triangle does. I can see flashing the vertical for a 2 section configuration, but not a 3 section. Plus, a flashing yellow means something else, and that's essentially what this is. I think it's one of those cases where someone overthought it.
I am the traffic signals crew leader in Syracuse NY where Crouse Hindes is located. We still have a couple PCE'S in operation
Thanks for sharing! Didn't realize from the engineering/planning perspective how much went into a standard LTI/LBI
It’s true…. It can be a lot of work!
My words of wisdom to engineers: “just because you can do something doesn’t mean you should do it “.

I forgot to mention that phase 9 is in ring 3

That’s what I determined as well. Seems so difficult to program for little benefit
It seems pretty clear in 8-C3 is there any more verbiage that has a variance on this? mutcd.fhwa.dot.gov/htm/2009/part8/fig8c_03_longdesc.htm
@@Petru.S Not too hard on an econolite EOS. It's just a setting per phase for LRT.
