Bridge Rails and Transitions for Pedestrian Protection

摘要

It is desirable to protect pedestrians on bridges from motor vehicles. However, transition problems rise at the ends of bridges where the bridge rail, bridge rail end treatment, and pedestrian walkway compete for the limited available space. The objective of this study was to identify the most common scenarios in which the protection of pedestrians on bridges is desirable, and then to develop bridge rail and bridge rail end treatment configurations to accommodate those situations. The objective was achieved by performing a field investigation, a survey of state transportation agencies, and a literature review. Recommendations for the placement and general design of standard barrier configurations have been provided in the form of thirteen generalized site drawings.
