Deflection/Clear Zone
To determine the expected deflection, refer to Figure 14 and determine the value for S (in feet)
for the site in question. S is the perpendicular distance from the face of the barrier out to the
nearest side of a reference vehicle (a 3/4 ton pickup truck) which is driving exactly in the center
of the lane furthest from the barrier.
Clear zone is defined by AASHTO Roadside Design Guide, 1989 and NCHRP 350 as:
“The total roadside border area, starting at the edge of the traveled way, is available for safe
use by errant vehicles. This area may consist of a shoulder, a recoverable slope, a non-
recoverable slope, and/or a clear run-out area. The desired width is dependent upon the traffic
volumes and speeds, and on the roadside geometry.” The clear zone must allow for the
deflection of the Triton Barrier

.
Except for an anchored rigid barrier, all barriers will experience some amount of deflection.
