Testing and Evaluation of Transition Designs for the New England Transportation Consortium

Project Description

In two previous projects, the New England Transportation Consortium (NETC) developed and crash tested two steel bridge rail systems¿a two-bar curb-mounted system and a four bar sidewalk-mounted system. The Federal Highway Administration (FHWA) Office of Highway Safety Infrastructure has concluded that both bridge rails are acceptable as TL-4 designs and may be used on the National Highway System. The objective of this project was to qualify transitions to the two bridge rail systems and to a concrete end wall that is used as a component of several bridge rail systems. The NETC New Hampshire transition to the two-bar steel bridge rail successfully contained and redirected the pickup for TL 3 test conditions. The NETC Massachusetts transition to the concrete end wall successfully contained and redirected both the pickup and the single unit truck for TL-4 test conditions. All occupant risk values were acceptable where applicable.
