Note: Read the question carefully and give me right solution according to the question. An existing vertical curve on a highway joins a +4 percent grade. Assume f=0.4 and perception-reaction time of 2.5 sec, and S< L. If the length of the curve is 225 ft, the maximum safe speed of the curve(mi/hr). What would you recommend as the speed limit for this vertical curve?
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?

Transportation engineering Read the question carefully and give me solution according to the question. Thank you. A horizontal curve of 6-lane divided highway is built in cut section of side slope 2:1. If the design speed is 100 km/h, station of PI is 60+00, lane width=3.6 m, e = 8 %, t = 2.5 sec, g = 2 %, and Δ=45°. Determine the min shoulder width that would allow a safe operation on this curve.
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?
Two straight sections of road are to be linked by a wholly transitional curve comprising two clothoid spiral curves with differing rates of gain of radial acceleration. Deflection angle between the two straight sections of road 43.5 Design Speed 75 Rate of gain of radial acceleration for entry transition curve 0.400 Rate of gain of radial acceleration for exit transition curve 0.600 Answers required: a) What is the value of the point radius where the two transition curves meet?
1. A road with a design speed of 55 mph has a utility pole located 27 ft from the edge of travel lane. If the ADT for the road is 1,850 vpd and the sideslope slopes down at a 1V:4H grade, is the utility pole located within the clear zone? 2. For the utility in Problem 1, will the utility pole be located too close to the road if it is on the outside of a horizontal curve with a radius of 2,000 ft?
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.
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.
During your internship, your supervisor asked you to design a horizontal curve with a 24-degree deflection angle for a two-lane road with 12-ft lanes. The design speed is 65 mi/h, and superelevation is limited to 4%. The point of intersection (PI) is located at 825+20, and the roadway is on level terrain. Design the horizontal curve.
A large grain elevator is located 40 feet from the centerline of a two-lane highway (55 mph speedlimit, 12-ft lanes and level terrain). The elevator is situated on the inside of a horizontal curvewith a radius of 500 feet measured to the centerline of the highway. Assuming that the elevatoris the only sight restriction on the curve, what is the available sight distance along the curve(measured to the center of the inside lane)? Does adequate stopping sight distance exist?
Calculate the minimum length af a crest vertical curve for a two lane highway with an initial grade of +3.5 and a final grade of -2% based on a Passing Sight Distance (PSD) of 700ft .(corresponding to a design speed of 45 mph), For Pasing Sight Distance, ASHTOO 2011 poicy assumes a driver eye height above the Roadway of 3.5 ft( i.e h1) and an object height of 3.5 (i.e h2),
