Question 4 4.1 A 2-lane road has a circular curve with a radius of 210 m, curve length of 300 m. The lane width and shoulder width are 3.6 and 1.8 m, respectively. The design speed on the road section is 80 km/h and minimum required SSD is 115 m. Determine the minimum acceptable distance of a building structure from the edge of the road. (4)

4.2 An 80 km/h rural road section has a three-leg intersection. Assume a WB50 design vehicle, determine the required shoulder sight distance for both stop and yield conditions. Show how you reach to the answers. (4) [8 Marks]

A minor road intersects a major 4-lane divided road with a design speed of 55mph and a median width of 8 feet. The intersection is controlled with a stop sign on the minor road. If the design vehicle is a passenger car, determine the minimum sight distance required on the major road that will allow a stopped vehicle on the minor road to safely turn left if the approach grade on the minor road is 3%.

ou are asked to design a horizontal curve for a two-lane road. The road has 12-ft lanes. Due to expensive excavation, it is determined that a maximum of 35 ft can be cleared from the road’s centerline toward the inside lane to provide for stopping sight distance. Also, local guidelines dictate a maximum superelevation of 0.08 ft/ft. Determine the design speed for this curve (mph)?
