BFS in an eight-lane freeway has two interchanges in six miles along level terrain. The lane width is 11-ft. The left shoulder is 5.0 ft. The right shoulder width is also 5.0 ft. The traffic volume in the analysis period is 3225 veh/h which consists of 14% heavy trucks. Assume PHF is 0.926. What is the LOS? To increase the FFS, the engineer decided to redraw the pavement marking to create four 12-ft lane per direction, with no left shoulder and a 6.0 ft right shoulder. What is the new FFS
