An elevated expressway goes through an urban area, and crosses a local street as shown in Figure 3.9. The partial cloverleaf exit ramp is on a 2% downgrade and all vehicles leaving the expressway must stop at the intersection with the local street. Determine (a) minimum ramp radius and (b) length of the ramp for the following conditions below:
Maximum speed on expressway = 60 mi/h Distance between exit sign and exit ramp = 260 ft Letter height of road sign = 3” Perception-reaction time = 2.5 sec Maximum superelevation = 0.08 Expressway grade = 0% Assume that a driver can read a road sign within his or her area of vision at a distance of 50 ft for each inch of letter height, and the driver sees the stop sign immediately on entering the ramp. What will be an ideal response?
