ATMS14-Advanced Railroad Grade Crossing (Market Package*)

Market Package Graphic       Transaction Set Diagram

Description

This market package manages highway traffic at highway-rail intersections (HRIs) where operational requirements demand advanced features (e.g., where rail operational speeds are greater than 80 miles per hour). This market package includes all capabilities from the Standard Railroad Grade Crossing Market Package and augments these with additional safety features to mitigate the risks associated with higher rail speeds. The active warning systems supported by this market package include positive barrier systems that preclude entrance into the intersection when the barriers are activated. Like the Standard Package, the HRI equipment is activated on notification by wayside interface equipment which detects, or communicates with the approaching train. In this market package, the wayside equipment provides additional information about the arriving train so that the train's direction of travel, estimated time of arrival, and estimated duration of closure may be derived. This enhanced information may be conveyed to the driver prior to, or in context with, warning system activation. This market package also includes additional detection capabilities that enable it to detect an entrapped or otherwise immobilized vehicle within the HRI and provide an immediate notification to highway and railroad officials.

Rural Development

For the Crash Prevention and Security Rural Development Track, this market package is highly applicable to rural user needs and suitable for the rural environment. It addresses the needs of the broad rural development track by the following: Systems that manage highway rail intersections by warning vehicle operators of train proximity and providing traffic control through barriers to prevent vehicle from entering rail/roadway to prevent accidents from occurring. System provides additional safety features to mitigate the risk associated with higher rail speeds. Data from the intersection is shared with the local traffic management agency.
