Evaluations of Low Cost Safety Improvements Pooled Fund Study


Evaluations of Low Cost Safety Improvements Pooled Fund Study (ELCSI–PFS) Annual TAC Meeting, 2007

Phase I–III Balloting Results

The goal of this research is to develop reliable estimates of the effectiveness of the safety improvements that are identified as strategies in the NCHRP Report 500 Guidebooks.  These estimates are determined by conducting scientifically rigorous before–after evaluations at sites in the U.S. where these strategies are being implemented.

The Strategies for each phase are selected by balloting in annual TAC Meetings. You can access the balloting results through the following links.
