1.2.7.5–Process Indicator Output Data for Freeways (Pspec*)
This process shall implement the indicator output data generated by other processes within the Manage Traffic function for use on freeways served by the function. It shall perform the functions needed to output control data to traffic meters and lane use indicators including those used for ramp, interchange, and mainline metering, reversible lanes, high-occupancy vehicle (HOV) or high-occupancy toll (HOT) lanes. This process shall provide the interface for data to be sent to the units (or systems) that manage multimodal crossings. 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*:
- Multimodal Crossing Control
- Roadway HOV Control
- Roadway Reversible Lanes
- Roadway Traffic Information Dissemination
- Roadway Traffic Metering
