The green ratio (g/c) is the ratio of effective green time of a phase to the cycle length.

The NB/SB Approach to the U.S. 95/Styner-Lauder Avenue intersection (U.S. 95) has a green ratio of 0.58.

g/c =   (Green Time for approach)/(Cycle Length for the Intersection)

                   (35 s) / (35 s + 25 s) = 0.58
