CO3 README.TXT file  November 18, 2009 by Robert I. Carr

Updates:

Nov 14, 1997: COFlag and COFlag 95 were updated on Nov 14, 1997 to allow
using capitalized letters (FLAG, FLAGGED, FLAGGING, etc.) as well as small
letters (Flag, flag, etc.) to identify periods of flagging. RICarr

Feb 3, 1998: CO and CO95 were updated on Feb 3, 1998 to implement direct
calculation of demand and delay for the common situation in which all of
a period's demand enters the zone at the same capacity. This produces 
slightly different answers than before, because it produces different 
starting points for iterative solutions. RICarr

May 28, 1998: CO and CO95 were updated to change the order of calculating 
decreases in demand and average decreases in demand. This corrected the 
Visual Basic spreadsheet calculation fault. "Calculate" is replaced by
"Compute" in the Traffic Sheet Summary View for clarity. RICarr

Nov 18, 2009: COFlag was updated May 21, 1999 to add calculation of backup
delay for vehicles arriving after flagging due to backup at end of flagging.
However, it was not updated at this site until 2009. Deleted compressed
files and Excel 95 files as confusing and no longer necessary.
