- W24284435 abstract "The Federal Highway Administration (FHWA) organized a Pooled Fund Study of 26 States to evaluate low cost safety strategies as part of its strategic highway safety effort. The purpose of the FHWA Low Cost Safety Improvements Pooled Fund Study is to evaluate the safety effectiveness of several of the low-cost safety strategies through scientifically rigorous crashbased studies. The goal of this research is to develop reliable estimates of the safety effectiveness of safety improvements identified as strategies in the NCHRP Report 500 Guidebooks or other high priority strategies as identified by the participating States. This paper provides the results of four strategies that were evaluated as part of this study: (1) Two-way left-turn lanes on two-lane roads, (2) STOP signs with higher retroreflectivity, (3) STOP AHEAD pavement markings at stop-controlled intersections, (4) Flashing beacons as stop-controlled intersections. The safety effectiveness of these strategies has not been thoroughly documented. This study is an attempt to provide an evaluation through scientifically rigorous procedures. Crash, volume, and roadway data were collected from nine different states to evaluate these strategies. The empirical Bayes methodology for observational before-after studies was used for these evaluations. An economic analysis was also conducted." @default.
