I created the matrix below to make it easier to develop the appropriate scope for a traffic study.  It's based on the Institute of Transportation Engineers' recommended practice Transportation Impact Analyses for Site Development and a host of government policies I was able to find online.  All you need to use it is the development's predicted peak hour traffic (here for more on that).  Caveat:  check the reviewing agency's policies – they trump this matrix.
