This report presents the results of an in-depth evaluation of bridge railing technology as related to levels of service. Multiple-service-level selection procedures were developed based on benefit/cost analysis technique. The complex probability equations were solved for most typical bridges and service levels identified from a set of four. In addition, a new low-cost bridge railing (estimated installed cost $10/ft) was designed, developed, and evaluated by crash test. Use of this new railing, which performs at a lower level than the current AASHTO criteria, could be widespread on low-volume roads on the basis of project findings. Finally, recommended revisions and additions to the AASHTO bridge railing specifications are offered.
