A two-lane highway along the border has a horizontal curve segment with radius of 656 ft (measured to the centerline that separates the two opposing lanes). If the superelevation is 4% and f = 0.10, what should be the posted speed limit? With this speed what is the SSD? If the lane width is 12 ft and the border wall is located at 30 ft from the continuous while line that separates the inner lane and the right shoulder. Calculate the available sight distance of the driver. Is the sight distance adequate?

A section of highway has vertical and horizontal curves with the same design speed. A vertical sag curve on this highway connects a +1% and a +3% grade and is 420 ft long. If a horizontal curve on this highway is on a two-lane section with 12ft lanes, has a central angle of 37 degrees, and has a superelevation of 6%, what is the length of the horizontal curve?

If a horizontal curve on this highway is on a two-lane section with 12-ft lanes and has a central angle of 37 degrees and a superelevation of 6%, what is the length of the horizontal curve?
A parabolic sag vertical curve is formed when a rural highway passes under a bridge joining a -6% grade to the horizontal grade. The vertical point of intersection of these two grades lies 3 feet below the curve. If the vertical clearance of the underpass is only 10 feet, what speed limit would you suggest should be imposed at this spot, considering a safe stopping sight distance? Use H=3.5 ft, β= 1.50; assume vehicle deceleration rate of 13.5 ft/s2 and driver’s perception-reaction time of 2.5 seconds.
Determine the minimum radius of a horizontal curve required for a highway if the design speed is 70 mi/h and the superelevation rate is 0.08.
A horizontal curve is to be designed for a section of a highway having a design speed of 60 mi/h. (a) If the physical conditions restrict the radius of the curve to 500 ft, what value is required for the superelevation at this curve?(b) Is this a good design?
A tow truck is searching a city street at 40 mi/h for illegally parked vehicles. It travels over an equal tangent vertical curve with an initial grade of +4.0% and final grade of -2.0%. If the height of the driver's eye is 6.0 ft and the driver spots a car 450 ft away with a height of 4.0 ft, what is the minimum length of the vertical curve for this situation?
When aligning a highway in a traffic area, it is necessary to provide a horizontal circular curve of radius 295 m , if the design speed is 60 kph , determine the superelevation rate. ( Superelevation to fully counteract centrifugal force use only 75% of the design speed).
A curve of 100 m radius (e=8.0 % and fs=0.14) is located at a section of an existing rural highway which restricts the safe speed to 55 % of the design speed causing a high accident rate. To reduce the accident rate, a new curve is to be designed. Determine the minimum radius of this curve if the safe speed should be increased to the design speed. Assume the same values of e and fs.
A horizontal curve on a two-lane highway is designed with a 610-m radius, 3.5-m lanes, and 80 kph design speed. Determine the distance that must be cleared from the inside edge of the inner lane to provide sufficient stopping sight distance. (Note: Curve radius is typically reckoned from the centerline of the roadway, and driver location is assumed to be at the middle of the travelled lane.) Assume coefficient of friction as 0.35. ANSWER M =4.0 ?
A delivery truck passes thru the expressway exit ramps at a design velocity of 50 kph. connects with a local road to allow ram traffic to turn right without stopping at an acceleration of 1.57 m/sq.s. The turning roadway has stabilized shoulders on both sides and provides for a one-lane one-way operation with no provisions for a passing stalled vehicle. Super elevation on the turning roadway is 0.08. Determine the minimum radius of curvature for the ramp in meters.
A section of a two-lane rural highway consists of a -3% grade intersecting a +4.5% grade. The speed limit on the highway is 55 mph. The height of headlights of an average car is 2.4 feet with a beam angle of 1.50. Determine the length of sag vertical curve that joins the two grades, considering a safe stopping maneuver
What is the appropriate super elevation rate for a curve with a 1,200-ft radius on highway with a design speed of 60 mi/h? The maximum design super elevation is 6% for this highway.
