CTC 440 - Homework 3 (Circular Curves)

1. The deflection angle between two tangents was measured and found to be 20 degrees-34minutes. It has been decided that a 2 degree-5 minute curve will be used to connect the tangents. The station at the PC is 10+00.

Find: R,T,E,M,L and the station at the PT

2. The deflection angle between two tangents is 1 deg-18 min-51 seconds. A curve with a 2,330.00-meter radius connects the two tangents. The station at the PC is 1+000.

Find: T,E,M,L and the station at the PT

3. Determine the median lane widths for the two remaining conditions (C1 and C2-symmetrical reverse curve) shown on the powerpoint slide (Use of RCC; Auxiliary Lanes)
