Interface: DDOT TMC - DDOT Traffic Signals
Architecture Flow Definitions
field device status (Planned) Applicable ITS Standards
Reports from field equipment (sensors, signals, signs, controllers, etc.) which indicate current operational status.
hri control data (Planned) Applicable ITS Standards
Data required for HRI information transmitted at railroad grade crossings and within railroad operations.
hri request (Planned) Applicable ITS Standards
A request for highway-rail intersection status or a specific control request intended to modify HRI operation.
hri status (Planned) Applicable ITS Standards
Status of the highway-rail intersection equipment including both the current state or mode of operation and the current equipment condition.
request for right-of-way (Existing and Planned) Applicable ITS Standards
Forwarded request from signal prioritization, signal preemption, pedestrian call, multi-modal crossing activation, or other source for right-of-way.
signal control data (Existing and Planned) Applicable ITS Standards
Information used to configure and control traffic signal systems.
signal control status (Existing and Planned) Applicable ITS Standards
Status of surface street signal controls including operating condition and current operational state.
speed monitoring information (Existing) 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 sensor control (Existing) Applicable ITS Standards
Information used to configure and control traffic sensor systems.
ups activation_ud (Existing)
Status information from field equipment (e.g., traffic signal controllers) sent when uninterruptable power supply (UPS) is activated/operational.
