Does anyone have the equations for the graphs and charts in the US MUTCD? I can't find them anywhere and need them to do precise calculations.
 
Yeah that has some of them but it doesn't have the equations specifically for warrant 4 and 9. That is helpful though. I'm really needing it for warrant 4.
 
DOT seems to imply there aren't any available.
At this point, I would suggest getting the best quality graph you can find and digitize the graphs. I use a very old program called Tracer for this sort of thing. The graph will need to be scrubbed to remove the grid lines within the graph, and you can use pretty much any photo-editing software for that. Tedious, but certainly doable. Seems like you could possibly make a name for yourself if you publish a polynomial fit to those curves.
