In a signal phase, pedestrians are allowed to cross the street walking in the same direction as movements #2 and #6. The distance from one side of the street to the next (length of the crosswalk) is 72 ft. The width of the crosswalk is 9.0 ft. What minimum green time should be set aside for 12 pedestrians (both directions combined) to cross per phase? Use the walking speed of 4.0 ft/s. Round your answer to the next second. Suggest a walk interval, pedestrian clearance interval, and
