Question

Example 10-6 A 2500-ft roadway centerline is established during a pre- liminary survey, as shown in Figure 10-5a. The three tangent sections are to be connected by two simple curves, the first with a radius of 700 ft and the second with a radius of 600 ft. Determine the stations of the PCs and the PTs, the total length of the centerline with curves, and the last station of the final route.
