ELCSI-PFS Publications

The goal of this research is to develop reliable estimates of the effectiveness of the safety and operational improvements identified by the ELCSI-PFS Advisory Committee (TAC). These estimates are determined by conducting scientifically rigorous before-and-after evaluations at sites in the United States where these strategies are being implemented. The ELCSI-PFS facilitates technology transfer and knowledge sharing among State members and FHWA stakeholders.
