As outlined in the Federal Highway Administration’s (FHWA) Systemic Safety Project
Selection Tool are the following:
• Identifies safety concerns based on an evaluation of data at the system level.
• Establishes common characteristics (risk factors) of locations where severe
crashes frequently occur.
• Given high aggregate numbers of target crashes but low average density per site
tends to deploy lower-cost countermeasures to many sites to affect a large number
of locations. (Preston et al., 2013)
The above principles can be described as the methodology to identify high-risk locations
for
crashes based on a data-driven approach (Preston et al., 2013). These steps assist in
finding the
type of crashes and the risk factor associated with the collision. The functionality of this model
might have the capability to provide some mitigation
measures.
