- for the utility in problem 8-3, will the utility pole be located too close to the road if it is on the outside of a horizontal curve with a radius of 2,000 f?A driver with 20/20 vision traveling at 55 mph in the median lane desires to exit the freeway at the exit ramp. If 5-in. letters are used, what is the minimum distance the sign should be placed ahead of the ramp exit? (Some assumptions that would be helpful are perception-reaction time = 2 sec; exit speed = 30 mph; deceleration rate = 4.80 ft/s2 a driver with 20/20 vision can read a sign at 55 ft per inch of letter height.) Discuss your results.Two adjacent signalized intersections along a major arterial are 650 ft apart (stop line to stop line distance). If the space mean speed between these two intersections is 22 mph, what should be the signal offset of the downstream intersection relative to the upstream intersection?
