Title: Signal Numbers for Reference
Post by: roadman65 on April 20, 2022, 03:55:45 PM
I noticed that along US 441 in Pigeon Forge, TN as well as Gatlinburg, TN, the two communities use signal numbers to identify locations of businesses near the signal or for giving directions to turn off US 441 at a specific signal.  The signals are numbered sequentially and therefore allows for one to home in on a specific signal number by simple math.  Almost like Exit numbers for the ramps on freeways but actual signalized intersections with numbers both communities use for tourists and locals alike.

I also noticed that a recent visit to Moss Point, MS showed me that its not only limited to Tennessee for this unusual practice.  Signals along US 90 also are also numbered in purple circles on the traffic signal mast arms all along the route (well at least from MS 603 to the Lowes Store) this past week.

Is this practice done in any other cities in the US?

Hendersonville, TN also does this along US 31E.  Likely copied from Gatlinburg.  I want to say other TN cities do this but I can't immediately think of any.  Possibly Oak Ridge.

Does anyone have pictures? Not that it was ever an expectation, but it would be cool to see.

The only time I've seen this was driving through Somerset, KY on US 27. I found it to be quite handy for counting down the signals until I made it through the town

The Kentucky example seems to be the best. The others are too concerned with being pretty to be useful for navigation.

Imagine if highway exit tabs were designed by municipalities. No thanks.

They seem to be more commonly found in Tennessee and Kentucky, and a few places in the South where there are a lot of visitors.

Here's one in Orange Beach, Alabama (I don't think I've seen them elsewhere in Alabama):

The obvious problem with this is that it only works well when there's one main drag through town with multiple stoplights. Otherwise, you end up in a situation where Signal 13 on one road is Signal 7 on the other, or else the signal numbering jumps around as streets intersect more major ones, and then the easy reference system falls apart.

The problem with the Kentucky example is that it is far more prominent than the actual street name, which is only shown on a ground-level blade. If I were passing through town and my itinerary told me to turn on Salee Street, I might well miss my turn because I interpreted the big green square 9 as meaning that this was 9th Street or county highway 9 or something similar to that.

The ones on US 90 in Mississippi run the entire length of the route (and from the Louisiana line to the Alabama border), all the way from Waveland to Pascagoula.

Ideally, you would have both a street name and a number. And yes, this method would only make sense in areas where there is only one main road with signals. Think Hilton Head Island or the Outer Banks.
