1.2.7.1–Process Indicator Output Data for Roads (Pspec*)
This process shall implement the indicator output data generated by other processes within the Manage Traffic function for use on the roads (surface streets) served by the function. It shall perform the functions needed to provide traffic control at intersections or pedestrian crossings, or provide the interface for data to be sent to the units (or systems) that manage reversible lanes, multimodal crossings or highway-rail intersections. This process shall monitor the status of the indicator equipment and provide data to the Manage Maintenance and Construction function to help that process determine whether the indicator is operating correctly or a repair is needed.This Pspec is associated with the Roadway Subsystem*.
This Pspec is associated with the following Equipment Packages*:
- Advanced Rail Crossing
- Multimodal Crossing Control
- Roadway Intersection Safety Warning
- Roadway Mixed Use Sensing
- Roadway Reversible Lanes
- Roadway Signal Controls
- Roadway Signal Preemption
- Roadway Signal Priority
- Roadway Traffic Information Dissemination
- Standard Rail Crossing
