The objective of the research is to develop more reliable ways to assess signalized intersection safety in Oregon so that ODOT and other agencies can allocate funding resources towards effective intersection safety configurations for both new and existing facilities. This will be accomplished by developing signalized intersection safety performance functions that explicitly consider approach speed as a direct input in safety assessment of the location.
