This should be easily and publicly available (and periodically disseminated). I lived in Pittsburgh for ~15 years and didn't know what it was. I came up with my own.
Now that I live in Spokane, I haven't seen one on their city web site. I looked because wildfires can be a danger (though not usually to the central city). So, I don't really know the preferred routes for getting the city evacuated if necessary.
