Cycle length equation

I recently came across an equation that gives a first cut at a possible cycle length for a coordinated roadway. I'm familiar with the Webster equation, but not this one: C=X(D/V) where C= cycle length, D= signal spacing, V=progression speed, and X = an integer (1,2,4, etc). Is anyone familiar with this equation as I do not understand how to choose an integer for the "X" value. What is the integer representing in this equation?
Thanks.

I've found what the integer is to do. It is providing optional cycle lengths that might be appropriate. After you divide the other part of the equation you get an approximate cycle length. If you multiply that by 1, 2, 4, or another even number you'll get a range of possible cycle lengths that should be an approxinmate starting point.

Question resolved.

Thx.
