Instruments for Surveying

Surveying is the practice that determines the relative three-dimensional positions of many different points on the earth’s surface. There are various instruments used in Surveying like Theodolites, Total station, Tripod stands, Plane table, etc. for measuring horizontal angle, vertical and sloping angle, which are very useful for giving accurate and precise measurement.

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.

Problem 2. A horizontal curve is being designed for a two-lane highway (12-ft lanes). The PC is at station 1200 + 50, the design speed is 70 mph, and a design superelevation of 0.08 ft/ft is to be used. Central angle of the curve is 40 degrees. (1) What is the min radius (measured to the centerline of the inside-most lane)? (2) Use the min value in your design, determine the station of PT.

A 5% grade intersects a -3.4% grade at station 41+990 of elevation 42.30 m. Design a vertical summit parabolic curve connecting the two tangent grades to conform with the following safe stopping sight distance specifications.Design Velocity = 60 kphHeight of driver's eye from the road pavement = 1.37 mHeight of an object over the pavement ahead = 100 mm Perception-reaction time = 3/4 sCoefficient of friction between the road and the tires = 0.15
A vertical curve is needed to join to tangents; G₁=2% and G2-5%. 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 comfort criteria. The design speed is 50 mph. Response Feedback: G2-G₁ is positive, therefore a sag curve. A=3 Lmin-AV²146.5
