• 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
