I've tested the second one above on a few different signs and found it to be fairly reliable. I created a metric guide for those living in the civilised world, and wrote a short blog for our customers.

No doubt someone will find some technical errors (like PPI vs DPI).

It's better to have two hands than one glove.
There's more to it than just the resolution of the image
Ideally you want to print at least 4 times the image resolution. This give you 16 printer pixels for each image pixel. On a 4 color printer this gives ~4^16 color possibilities for each image pixel. Just what you want.
Then consider that the unaided and non-mutant human eye has a hard time discerning 1 part in 100. That's why a 130 line screen is pretty much the standard for halftone work.
In this shop everything is printed at 720dpi and virtually all bitmap images are sent in RGB at 150ppi. Exceptions for huge things to be mounted far away from any observer are considered but 150ppi and 720dpi represents 99% of all printing done here and there is no reason whatsoever to deal with any higher resolutions. There's never been a complaint in all these years doing it this way.

As pointed out by others, the charts I provided were PPI - what your file setup should be within your image editing software. Printer resolution (DPI) should always be higher. For me this is easier to determine with a hands on approach by printing samples. With most wide format machines there will be other settings that change with DPI, like number of passes, that can also have an effect on the final output.
