Determining Line Direction for Historical Traffic Data

This question relates to my use of Network Analyst extension, but has an editing component to it. I need to determine the direction of which my street lines were created. What direction is taken from the first edited point to the last? Network Analyst is using a bunch of To and From information to create historical traffic patterns based on the street side edges. However, my Street Centerline was a file from our County government. So, I am not fully sure that they consistently have the lines flowing in the same direction. My eventual use is to compare the direction the street was digitized to determine a To/From direction for the lines. Then attribute my GPS data, with a heading, to the appropriate To/From edge of the line. Any ideas?
