A pretimed four-timing-stage signal has critical lane group flow rates for the first three timing stages of 274, 114, and 271 veh/h (saturation flow rates are 1600 veh/h/ln for all timing stages). The lost time is known to be 4 seconds for each timing stage. If the cycle length is 80 seconds, what is the estimated effective green time of the fourth timing stage? Input your answer in seconds in the form 0.00.
