Problem 3: Curve Reassessment Along Osmeña Highway (15 points) A curve near a residential portion of Osmeña Highway has raised safety concerns after several near misses. The curve has a radius of 160 meters, and the posted speed limit is 60km//h, which engineers claim is only 75% of the actual design speed. The curve is currently banked with a superelevation of 0.07. The city is considering increasing this to 0.10 to enhance safety. Estimate the current design speed of the curve based on existing radius and superelevation. (5 pts) Calculate the minimum required radius for a posted speed equal to the design speed. (5 pts) Recalculate the minimum radius with the new superelevation of 0.10. (5 pts)
