b) The vertical alignments of two roads A and B are to be design with speeds 60km/hr and 80km/r, respectively. Differentiate between the two roads in terms of the level of applicable design standards and the expected cost of implementation.
A new basic freeway segment will have 3 lanes in each direction. The left and center lane each has a width of 12 ft while the width of the right lane is 13 ft. The left shoulder is 4 ft while the right shoulder is also 4 ft. There are 2 interchanges within 6 miles (3 miles upstream and 3 miles down stream).The site has level terrain, the design speed is 80 mph the hourly design volume is 5250 veh/h, which includes 9.0% trucks and buses. The peak hour factor is 0.870.  Calculate FHV, VP, FFS, LOS Show all work
3.15 Due to crashes at a railroad crossng, an overpass (with a roadway surface 7.5 m above the existing road) is to be constructed on an existing level highway. The existing highway has a design speed of 80 km/h. The overpass structure is to be level, centered above the railroad, and 60 m long. What length of the existing level highway must be reconstructed to provide an appropriate vertical alignment?
