The Federal Highway Administration (FHWA) organized 26 states to participate in the FHWA Low-cost safety improvements pooled fund study as part of its strategic highway safety plan support effort. The purpose of the pooled fund study is to estimate the safety effectiveness for several of the unproven, low-cost safety strategies identified in the National Cooperative Highway Research Program (NCHRP) 500 Series reports. One of the strategies chosen to be evaluated for this study was ad-vance street name signs at signalized intersections. This strategy is intended to reduce the frequency of older driver crashes and crashes related to way-finding (i.e., rear-end and sideswipe crashes) at signalized intersections. Advance street name signs have the potential to reduce way-finding crashes because they provide drivers with additional time to make necessary lane changes and route selection decisions. The safety effectiveness of this strategy has not been thoroughly documented; this study is an attempt to provide a crash-based evaluation through scientifically rigorous procedures.
