Abstract:
This paper summarizes the validation of prototype vehicle-to-infrastructure (V2I) safety applications based on Dedicated Short Range Communications (DSRC) in the United States under a cooperative agreement between the Crash Avoidance Metrics Partners, LLC (CAMP) and the Federal Highway Administration (FHWA). After consideration of a number of V2I safety applications, Red Light Violation Warning, Curve Speed Warning (CSW) and Reduced Speed Zone Warning with Lane Closure Warning (RSZW/LC) were designed, developed tested and demonstrated using seven different vehicles (six passenger vehicles and one class 8 truck) leveraging DSRC-based messages from a Road Side Unit (RSU). Along with application development, an extensible, containerized message was developed to deliver required infrastructure data to the vehicle-based application in a single message leveraging existing SAE J2735 data elements. More than twenty distinct scenarios were designed to test and document system performance against requirements and more than one hundred test runs were conducted using both light- and heavy-duty vehicles over a period of seven months. Subsequently, additional on-road engineering testing of CSW on public road and RSZW/LC in live work zone were conducted in South East Michigan. Application performance analysis revealed that proper and accurate infrastructure maps are essential for the correct functioning of the V2I safety applications.
