SPF Selection Target SPFs (essentially the roadway characteristics.	SPFs are applied to each roadway by default. A screening can then be done across diverse roadway types, allowing for a more accurate metric of comparison. AASHTOWare Safety Network Screening allows you to select the roadways you would like to analyze, and the appropriate SPFs will be utilized in any Predicted or Expected ranking criteria.
