Design a vertical curve (i.e., Determine length of the curve as well as station and elevation of the vertical curve's PVC and PVT) with the given PVI (station and elevation given the figure below) to go through a future intersection location at the point at which the vertical curve is flat. Report the vertical curve's design speed to the nearest 5 miles per hour. PVC Future Intersection Station = 100+00 G1 = -2.6% PVT PVI G2 = 1.0% Station = 99+00 Elevation = 228 ft %3|
QUESTION 3 A vertical curve is needed to join to tangents; G₁-5% and G₂-2%. Assuming the worst case scenario for braking, and the AASHTO recommended values for deceleration and perception-reaction time, calculate the minimum length of curve (ft) needed to satisfy the safety criteria. The design speed is 50 mph.
A curve of radius 250 ft and e 0.08 is located at a section of an existing rural highway, which restricts the safe speed at this section of the highway to 50% of the design speed. This drastic reduction of safe speed resulted in a high crash rate at this section. To reduce the crash rate, a new alignment is to be designed with a horizontal curve. Determine the minimum radius of this curve if the safe speed should be increased to the design speed of the highway. Assume fs= 0.17 for the existing curve, and the new curve is to be designed with e = 0.08
Highway problem.
A vertical curve was designed in 2006 for SSD requirements at a design speed of 120 km/h to connect grades G1 = +1% and G2 = -2%. The curve is to be redesigned for 120 km/h design speed in the year 2050. Vehicle braking technology has advanced such that vehicle deceleration rate has increased by 40% relative to 3.4m/s2 value used in the original design. However, due to the higher percentage of older people in the driving population, design reaction times have increased by 20%. Also, because vehicles have become smaller, the driver’s eye height is assumed to be 0.9 m above pavement. Compute the difference in design curve lengths for the 2006 and 2050 designs. Assume heye =1.08 and hobs = 0.60 m.
A horizontal curve is to be designed to connect two tangents on a rural principal arterial with a design speed of 110 km/h. The station of the BC is 545+13.65. It is expected that an existing building will be located at a distance of 15 m from the centerline of the inside lane. Determine the minimum radius that will satisfy the sight distance and superelevation requirements.
