摘要：	In 2004, the Michigan Department of Transportation (MDOT) began a comprehensive program to implement engineering countermeasures to address the needs of older drivers. The countermeasures included the use of Clearview Font on Guide Signs (freeway and non-freeway), installation of Box Span signals, installation of pedestrian countdown signals, use of Fluorescent Yellow Sheeting on warning signs, and use of arrow-per-lane on guide signs. This study aimed at evaluating safety benefits of the selected countermeasures. Evaluation was performed through a perception survey of Michigan drivers and analysis of crash data. Safety Performance Functions (SPF) for these improvements were developed as part of the study. Crash Modification Factors (CMF) for each countermeasure were developed through the before-after analysis of crash data. Finally, the benefit cost analysis of each countermeasure was performed and is documented in this report.
