Q3: What is the minimum radius of horizontal curve for a design speed of 90 kph ?

Design a Two way - one lane Highway with the following specification. V= 90 kph e=0.05 m=15 m SD=115 m wheel base = 2.25 m C=3 Pavement is rotated at center I =20 Determine the following: Minimum Radius Road Widening Transition Spiral (if any) Vertical Curve Tangent and Length of Curve Road Profile for horizontal alignment with station if the start station is 1+ 000

Given the proposed longitudinal profile of the centerline of a rural two-lane highway as follows: PVLu STN 10+0) PVL: Elev. 100 ft G-2% Ge0% L=? Ly=? a) Calculate the required minimum design lengths (to meet the SSD requirements) of the three back-to-back vertical curves on this section of the roadway to accommodate a continuous design speed of 50 mph.

Quickly please I need help please

A highway curve will pass through a railway and grade. The crossing must be at station 4 + 310 and at elevation 220 3.38 m. the initial grade is + 2% and meets a -3% grade at station 4 + 235 at an elevation of 223.38 m. the rate of change must not exceed at 2%. Compute the length of curve, station and elevation of highest point also check if the condition of rate of change is meet.

Determine the length required for the exit ramp having a downward slope of 2% and with the following information: Expressway Speed = 96 kph Exit sign letter height = 3 in Exit sign is located 80 m. from exit ramp. Motorist can see 1 in. of letter height at 50 ft. Perception-Reaction Time = 2.5 sec Friction = 0.35 %3D

A -1% grade meets a +3% grade at sta. 12+00 and elevation 520 ft. by a vertical curve of length 200 ft. Calculate the following: i. K and r ii. Station of PVC and PVT iii. Elevation of point at a distance, L/4, from PVC and PVT iv. station of turning point v. elevation of turning point vi. elevation of mid-point of the curve
