NCHRP Report 350 Test 4-11 of the New York Two-Rail Curbless Bridge Railing
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.
