Hi there! Just now finding your channel. Eau Claire area signal enthusiast here. Dane county signals in general have always intrigued me for their variation from most of the state standard in some places. I see they are still doing a lot of the trombone + reverse trombone arms with the vertical signal head per lane instead of monotubes, id imagine for cost of installation purposes.
@JMANWiSS monotube structures are expensive to build, expensive to maintain, often their bases don't fit in urban environments due to underground utilities, and I've found many consultants become over reliant on them for "safety" and actually make intersections worse thinking just updating to monotube structures IS the safety improvement. Lazy engineering.
@@EngMadison The biggest thing is the signal head per thru lane. Up here trying to retrofit median reversed trombone arms onto the existing base locations results in offset arms. But DOT has been doing a lot of these dual trombone arms setups for a couple years now on the two laners. I've yet to see NW region do more than one head per trombone arm though.
@@TheTrafficTech 3.5 fps, measured from curb to median curb of longest crossing. Then we use a longer walk, unless the median button is pushed, then it's a shorter walk.

Very cool! How many feet per second do you use for your ped clearance?
