Example 15.8 Location of Object Near a Horizontal Curve
A horizontal curve with a radius of 240 m connects the tangents of a two-lane
highway that has a posted speed limit of 56 kmph. If the highway curve is not super-
elevated, e =
board can be placed from the centerline of the inside lane of the curve, without
reducing the required SSD. Perception-reaction time is 2.5 s, and f 0.35.
