A safety performance evaluation of the 29-in. Nebraska Open Concrete Bridge Rail was conducted for the Nebraska Department of Roads (NDOR). The evaluation included computer simulation modelling and two full-scale vehicle crash tests. The two crash tests were conducted to evaluate structural adequacy of concrete posts adjacent to a gap and the reduced reinforcement in the concrete rail, respectively.

The objective of the research project was to collect crash test data relating to bridge rails and median barriers, to collect information about common attachments to traffic barriers, and to evaluate this information for the purpose of developing guidelines for the design and placement of traffic barrier attachments. A comprehensive review of full-scale crash testing of bridge rails and median barriers was conducted in order to establish Zones of Intrusion (ZOIs) for traffic barriers. The primary goal of this review was to identify the extent that a pickup or single-unit truck intrudes over the top of a traffic barrier during a vehicular impact.

A combination traffic and bicycle bridge rail was developed and crash tested. The combination bridge rail was constructed with a standard New Jersey safety shaped barrier and special steel panels formed from tubular steel posts and rails, and square vertical spindle bars. Two cables were installed inside the tubular rails to prevent detachment of large pieces of debris from causing hazardous conditions for vehicles and pedestrians below. Although the crash tested bridge rail was constructed using the New Jersey safety shape, it is believed that this combination traffic/bicycle bridge rail could be easily adapted to other safety shape barriers or rectangular parapets with no need for further crash testing. Due to the modular nature of the steel panel sections, the combination traffic/bicycle bridge rail can be repaired very easily following a vehicular impact. Two full-scale vehicle crash tests were performed on Minnesota's combination traffic/bicycle bridge railing. The tests were conducted and reported in accordance with the requirements specified in NCHRP Report No. 350, "Recommended Procedures for the Safety Performance Evaluation of Highway Features" (1993). The safety performance of the combination traffic/bicycle bridge rail was determined to be acceptable according to Test Level 4 of the NCHRP Report No. 350 criteria
