Interface: Pasco Traffic Operations Center - Pasco Field Equipment
Architecture Flow Definitions
hri control data (Existing) Applicable ITS Standards
Data required for HRI information transmitted at railroad grade crossings and within railroad operations.
hri request (Existing) Applicable ITS Standards
A request for highway-rail intersection status or a specific control request intended to modify HRI operation.
hri status (Existing) Applicable ITS Standards
Status of the highway-rail intersection equipment including both the current state or mode of operation and the current equipment condition.
right-of-way request notification (Existing) Applicable ITS Standards
Notice that a request has occurred for signal prioritization, signal preemption, pedestrian call, multi-modal crossing activation, or other source for right-of-way.
roadway warning system control (Planned) Applicable ITS Standards
Information used to configure and control roadway warning systems.
roadway warning system status (Planned) Applicable ITS Standards
Current operating status of roadway warning systems.
signal control commands (Existing) Applicable ITS Standards
Control of traffic signal controllers or field masters including clock synchronization.
signal control device configuration (Existing) Applicable ITS Standards
Data used to configure traffic signal control equipment including local controllers and system masters.
signal control plans (Existing) Applicable ITS Standards
Traffic signal timing parameters including minimum green time and interval durations for basic operation and cycle length, splits, offset, phase sequence, etc. for coordinated systems.
signal control status (Existing) Applicable ITS Standards
Operational and status data of traffic signal control equipment including operating condition and current indications.
signal fault data (Existing) Applicable ITS Standards
Faults from traffic signal control equipment.
signal system configuration (Existing) Applicable ITS Standards
Data used to configure traffic signal systems including configuring control sections and mode of operation (time based or traffic responsive).
speed monitoring control (Planned) Applicable ITS Standards
Information used to configure and control automated speed monitoring, speed warning, and speed enforcement systems.
speed monitoring information (Planned) Applicable ITS Standards
System status including current operational state and logged information including measured speeds, warning messages displayed, and violation records.
traffic flow (Existing) Applicable ITS Standards
Raw and/or processed traffic detector data which allows derivation of traffic flow variables (e.g., speed, volume, and density measures) and associated information (e.g., congestion, potential incidents). This flow includes the traffic data and the operational status of the traffic detectors.
traffic images (Existing) Applicable ITS Standards
High fidelity, real-time traffic images suitable for surveillance monitoring by the operator or for use in machine vision applications.
traffic probe data (Planned) Applicable ITS Standards
Vehicle data that is used to determine traffic conditions. In a basic implementation, the data could be limited to time stamped unique identifiers that can be used to measure a vehicle’s progress through the network. In more advanced implementations, the vehicle may report current position, speed, and heading and snapshots of recent events including route information, starts and stops, speed changes, and other information that can be used to estimate traffic conditions.
traffic sensor control (Existing) Applicable ITS Standards
Information used to configure and control traffic sensor systems.
video surveillance control (Existing) Applicable ITS Standards
Information used to configure and control video surveillance systems.
