Abstract:This report presents the potential safety benefits of wireless communication between the roadway infrastructure and vehicles,
(i.e., vehicle-to-infrastructure (V2I) safety). Specifically, it identifies the magnitude, characteristics, and cost of crashes that
would be targeted with currently proposed V2I for safety application areas including intersections, speed management,
vulnerable road users, and other safety applications areas. It also identifies the magnitude, characteristics, and cost of the
remaining crashes that are not targeted by currently proposed V2I safety applications. The results of this study indicate that the
applications are well conceived and can potentially treat large portions of U.S. crashes and crash costs. The characteristics of
unaddressed crashes provide a starting point for identifying either new applications or modifications to current applications.
