Methods of Surveying

Surveying is the practice to determine the relative three-dimensional positions of various points on the earth’s surface. This is done by computing the vertical and horizontal distances, angles between the points, collecting the observations, and plotting them on a map of any appropriate scale. Accuracy can be achieved by using the latest instruments like a theodolite, tachometer, etc. Leveling is a subdivision of surveying where the objective is to locate the elevation of objects considering a datum level.

4. Horizontal Curve: P.C. 12+00.00 P.I T 4= 30° P.T. This highway has a 60 mph speed limit requiring a minimum radius for any curve to be 1500'. If the curve is to begin at Station 12+00.00 and is to have a radius of 1610.10', how long will the curve be? At what station will the PI and PT go? How long will E be? (Answers should all be in hundredths.)
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.

There is a need for conducting a design check for a horizontal curve (flat terrain) for an intermediate speed highway in rural Victoria. Given the design speed is 80kmph and superelevation is 7%. The provided horizontal curve radius is 700m. Would the designed curve radius will be sufficient to attain the superelevation? If not, what would be the correct radius for horizontal curve? When suggesting a new radius please check and make sure that the provide superelevation is higher (>7%) than required.
