1.2.7.13: Provide Device Interface for Field Management Stations

This process shall provide the interface between roadway devices and other signal systems or Field Manage Stations (considered to be contained in the Other ITS Roadway Equipment terminator) for the exchange of data, status, fault indications, and control. The Other ITS Roadway Equipment can be adjacent geographically, under control of a different jurisdiction, or part of a more complex hierarchy. This process supports the interconnection of traffic signal controllers in peer or hierarchical arrangements, and may also be used to exchange information between a Signal Systems Master (SSM) and Signal System Local (SSL) equipment.

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

This process is associated with the following functional objects:

• Roadway Field Management Station Operation
• Roadway Signal Control

This process is associated with the following data flows:

• tors-signal_control
• tors-signal_status
• tors-signal_fault
• fors-signal_control
• fors-signal_status
• fors-signal_fault
• f_other_rw_ic_to_ic
• t_other_rw_ic_to_ic
• field_management_station_fault_indication
• field_management_station_status
