A signalized intersection has a cycle length of 70 seconds. For one traffic movement, the displayed all-red time is set to two seconds
while the displayed yellow time is five seconds. The effective red time is 37 seconds and the total lost time per cycle for the
movement is four seconds. What is the displayed green time for the traffic movement in seconds (whole number). Blank 1
