Meeting Minutes



This standard defines the logical and physical interfaces, and the performance attributes for the interface between the rail subsystem and the highway subsystem at a highway rail intersection.


Coordination between the rail subsystem and the highway subsystem is part of creating a National ITS covering multiple modes.  Existing standards address analog interfaces between these subsystems at the highway rail intersection.  This standard will extend that information to include serial digital communication.  Standardizing the interface will allow interoperability between a wide variety of equipment and enhance safety through a set of well-defined interface and performance attributes.
