A model known as stopping sight distance is used by civil engineers to design roadways. This simple model estimates the distance a driver needs in order to stop his car while traveling at a certain speed after detecting a hazard.
A model known as stopping sight distance is
used by civil engineers to design roadways. This
simple model estimates the distance a driver
needs in order to stop his car while traveling at
a certain speed after detecting a hazard. The
model proposed by the American Association
of State Highway and Transportation Officials
(AASHTO) is given by
V²
S =
2g(f±G)
+TV
where
S = stopping sight distance (ft)
V = initial speed (ft/s)
g = accelaration due to gravity, 32.2 ft/s?
f = coefficient of friction between tires
and roadways
G = grade of road
T = driver reaction time (s)
