The design speed for a two-lane highway (lane width=12 ft.) is 60 mph. The localjurisdiction governs 8% superelevation. The central angel of the curve is 40 degrees. The PI station is at 452+50.What is the curve radius to the travel path (R)? What is the curve radius (R)? What is the curve length (L)? What isthe station of PC? What is the station of PT? What is the SSD? How many feet must be cleared from the lane'sshoulder edge to provide adequate stopping sight distance?
A horizontal curve is being designed for a new two-lane highway (3.6-m lanes).
The PI is at station 7 + 640, the design speed is 105 km/h, and a maximum superelevation of
0.08 m/m is to be used. If the central angle of the curve is 35 degrees, design a curve for the
highway by computing the radius and stationing of the PC and PT.
A horizontal curve on a four-lane (two lane in each direction) highway (11-ft lanes) has PC at station 124+30 and PT at station 130 + 15. The central angle is 40
degrees, the superelevation is 0.12, and 23.5 ft is cleared (for sight distance) from the inside edge of the innermost lane. Determine a maximum safe speed
(assuming current design standards) to the nearest 5 mi/h.
