1- A two-lane highway (two 3.6 m lanes) has a posted speed limit of 100 km/h and, on
one section, has both horizontal and vertical curves, as shown in the figure below. A
recent daytime crash (driver traveling westbound and striking a stationary roadway
object) resulted in a fatality and a lawsuit alleging that the 100 km/h posted speed
limit is an unsafe speed for the curves in question and was a major cause of the crash.
Evaluate and comment on the roadway design (after Mannering and Washburn).
