1.6.3.1: Interact with Wayside Systems

This process is responsible for interfacing to railroad owned and maintained wayside equipment, such as Wayside Interface Units, Crossing Gate Controllers, etc. All these devices are expected to provide real-time information to the HRI about approaching trains and their own health. In addition, advanced implementations will make use of a communications path back to approaching trains provided by the railroad's equipment.

This process is associated with the ITS Roadway Equipment physical object.

This process is associated with the following functional objects:

• Roadway Advanced Rail Crossing
• Roadway Standard Rail Crossing
• Roadway Transit Signal Control

This process is associated with the following data flows:

• approaching_train_announcement
• ats_alert
• ats_status
• fwe-approaching_train_announcement
• fwe-train_data
• fwe-wayside_equipment_status
• hri_reporting_data
• twe-hri_status
• twe-stop_highway_indication
• twe-stop_train_indication
• wayside_status
• approaching_train_data
