This report will be of interest to researchers and those who select, locate,
and design traffic barriers. It documents the results of a crash test of a New
York Two-Rail Bridge Rail. This was the second test of a series intended to
evaluate this new bridge rail design. The objective was to see if it meets Test
Level Four (TL-4) in NCHRP Report 350. In this test, a 2000-kg pickup truck
impacted the bridge rail at a nominal speed and angle of 100 km/h and 25 degrees.
The bridge rail contained the vehicle and redirected it. At this time there
is no widely accepted measure of occupant risks associated with deformations
or intrusions into the passenger compartment. Of necessity, this factor must
be assessed in large part by the judgement of the test agency and the user agency,
or both. The researchers have concluded that this bridge rail did not meet evaluation
criteria D and K for Test No. 4-11 in NCHRP Report 350 due to separation in
the floor plan and excessive deformation of the occupant compartment.

16. Abstract
This report presents the details and results of New York Two-Rail Curbless
Bridge Railing and the results of the small car test -- National Cooperative
Highway Research Program (NCHRP) Report 350 test designation 4-11, which
is the 2000-kg pickup truck impacting the critical impact point (CIP)
at 100km/h and 25 degrees. The New York Two-Rail Curbless Bridge Railing
did not meet criteria D and K of NCHRP 350 test designation 4-11, due
to separation in the floor plan and excessive deformation of the occupant
compartment.
