• Abstract:
  This research project focuses on the interactions between guardrails and curves, and their confounding relationships with crash incidents. As such, the goals of this work is to assess the impacts of the presence of guardrails and the locations of horizontal and vertical curves on crash outcomes and to help determine the contexts in which safety interventions may be warranted. Specifically, there are two project objectives: ; Objective 1: Provide guidance on the contexts in which the use of guardrails is appropriate. This includes taking into account of the road geometries, the traffic characteristics, road conditions, and other relevant factors. ; Objective 2: Determine horizontal and vertical curve characteristics that are correlated with crashes to help identify locations where safety interventions may be warranted. Similar to Objective 1, this would include taking into account of the traffic characteristics, road conditions, and the presence of guardrails.
