§ 71.07 – What is an expansion factor?

(a)    A measure of actual services operated during a given duration of time. 

(b)   It is used to convert sample averages to totals in the given duration.  The total number of one-way bus trips operated during an entire report year is an example of an expansion factor in actual services operated; when multiplied by sample average PMT per one-way bus trip, it yields a measure of annual total PMT.
