• 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-NHS 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. ; In an effort to maximize the safety benefits of the limited funding, KDOT undertook the effort outlined in this report to ; establish practical risk-based guidelines and policies for bridge rails and guardrails on low-volume local roads
