A roadway goes from tangent alignment to a 250-m curve (spiral-circular-spiral) by means of a 90-m long circular and two similar 80-m long spiral transition curves. The deflection angle between the tangents is 45°. Use formulas to compute X, Y, p and k. Assume that the station of the PI measured along the back tangent is 250+000, and compute the stations of the TS, SC, CS and ST. Prepare a table for the first spiral curve giving coordinates, spiral angles, deflection angles and chords (from TS) for full stations and +20 points.
