This project is being created to continue activities from Pooled Fund Project TPF-5(317) Evaluation of Low-Cost Safety Improvements (ELCSI-PFS) Evaluations of Low Cost Safety Improvements Pooled Fund Study (ELCSI–PFS) | FHWA (dot.gov). ELCSI–PFS has been conducted under and supported by the Development of Crash Modification Factors (DCMF) program. The ELCSI–PFS, which consists of 41 State department of transportation (DOT) members, has provided technical feedback on priority safety improvement evaluations to the DCMF program for low- to high-cost improvements and implements new safety improvements to facilitate evaluations.

The goal of this research is to develop reliable estimates of the effectiveness of the safety improvements identified as strategies, including but not limited to, those in the National Cooperative Highway Research Program (NCHRP) Report 500 Guidebooks. These estimates will be determined by conducting scientifically rigorous before-and-after evaluations at sites in the United States where these strategies are being implemented. This work will support efforts towards Vision Zero and the Safe Systems Approach.  

The scope of the ELCSI–PFS is to conduct a research project of the priority strategies, including but not limited to, those in the NCHRP Report 500 Guides, and to provide reliable measures for effectiveness of various low-cost safety improvements. Previously in TPF 5(317), a target of 20 strategies totaling $4.38 million over 5 years was originally planned for in four phases. That study outperformed its original goals and added 9 extra phases for a total of 13 phases. We anticipate similar performance over the next five years. 

SPR-B Waiver was approved.

Recommended minimum yearly commitment for duration of study: $10,000-$50,000/year. Please contact Woon Kim, woon.kim@dot.gov, to discuss alternative options.
