3. A building is located 8.8 m from the centerline of the inside lane of a curved section of highway
whose radius is 145 m. the road is level and e is equal to 0.10. Determine the maximum possible
design speed. Assume the longitudinal and lateral coefficients of
friction are equal to 0.35 and 0.13, respectively.
Ensure you check speed for both stopping sight distance and vehicle stability. Assume a standard
perception-reaction time of 2.5sec.
2. A driver traveling at 70 kph sees a stalled car 30 m ahead. If the driver applies the brakes immediately (perception
- reaction time is zero) and begins slowing the vehicle at 8 m/sec2 (emergency deceleration), how far from the
stalled car will the car stop to avoid hitting the stalled vehicle?

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.
