- Problem 3: Highway segment is going under planning review. Given the following facts: Lane Width = 3.4 m Number of Lanes (N) - 2 (in cach direction) Total Lateral Clearance = 3.0 m Median No Median The 85th % Speed was found to be 100 km/hr (i.e. BFFS = 100 km/hr) PHF - 0.83 Terrain Type: Rolling You are asked to: A. Determine the maximum peak-hour volume that the segment can serve at a LOS C. B. Make suggestions on how to increase the total capacity while maintaining the LOS at C without major investments.arrow_forwardWhat should be the design minimum acceleration lane length for a flat parallel-type entrance ramp/curve terminal with a design speed of 45mph connecting to a highway with a design speed of 70 mph at a grade separated interchange?arrow_forwardA grade of 0.4 percent is being considered for a mountain roadway.
