• Abstract:
  The determination of warrants for bridge railing and approach guardrails is a ; fundamental roadside safety issue. These are specialized roadside safety barriers that are ; intended to capture and smoothly redirect errant vehicles that leave the roadway either ; on the bridge itself or on the approach to the bridge. ; The Federal Highway Administration (FHWA) requires tested bridge rails and ; approach guardrails on all National Highway System (NHS) Roadways. However, ; states are given the discretion ; to develop their own policies ; for non-NHI roads. Currently in ; Kansas, all bridges constructed ; with federal funds are required ; to have one of the Kansas ; Department of Transportation’s ; (KDOT) standard bridge rails ; (either corral rail or barrier curb) ; and approach guardrail (including ; transition and end treatment). ; These systems are expensive in ; terms of the initial cost of a bridge ; and they have additional safety ; and maintenance considerations ; that may outweigh the expected ; safety benefits on many low-volume applications
