Intelligent Transportation Systems Joint Program OfficeFederal Highway AdministrationThis document is the fifth of a seven volume report that describe the Performance Requirements for the connected vehicle vehicle-to-infrastructure (V2I) safety applications developed for the U.S. Department of Transportation (U.S. DOT). This volume describes the Performance Requirements for the infrastructure and vehicle components of the Spot Weather Information Warning \u2013 Reduced Speed V2I Safety Application. This application is designed to advise drivers of current adverse weather conditions in an upcoming weather zone and provide an alert if the vehicle\u2019s speed may be too high to safely traverse the zone. The safety applications described here integrate roadside and in-vehicle advisories, alerts and warnings to make the driver aware of hazards in time to take action to prevent a potential crash. The performance requirements provide requirements for both infrastructure and vehicle application components to ensure the messages are consistent and coordinated, to best capture the attention of the driver and to avoid conflicting or confusing driver messaging.17
