Interface: Aztec Field Devices - Aztec Traffic Management

Aztec Field Devices to Aztec Traffic Management Interface Diagram

Architecture Flow Definitions

field device status  (Planned)  Applicable ITS Standards

Reports from field equipment (sensors, signals, signs, controllers, etc.) which indicate current operational status.

right-of-way request notification  (Planned)  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 information system data  (Planned)  Applicable ITS Standards

Information used to initialize, configure, and control roadside systems that provide driver information (e.g., dynamic message signs, highway advisory radio, beacon systems). This flow can provide message content and delivery attributes, local message store maintenance requests, control mode commands, status queries, and all other commands and associated parameters that support remote management of these systems.

roadway information system status  (Planned)  Applicable ITS Standards

Current operating status of dynamic message signs, highway advisory radios, beacon systems, or other configurable field equipment that provides dynamic information to the driver.

signal control commands  (Planned)  Applicable ITS Standards

Control of traffic signal controllers or field masters including clock synchronization.

signal control device configuration  (Planned)  Applicable ITS Standards

Data used to configure traffic signal control equipment including local controllers and system masters.

signal control plans  (Planned)  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  (Planned)  Applicable ITS Standards

Operational and status data of traffic signal control equipment including operating condition and current indications.

signal fault data  (Planned)  Applicable ITS Standards

Faults from traffic signal control equipment.

signal system configuration  (Planned)  Applicable ITS Standards

Data used to configure traffic signal systems including configuring control sections and mode of operation (time based or traffic responsive).

traffic flow  (Existing and Planned)  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  (Planned)  Applicable ITS Standards

High fidelity, real-time traffic images suitable for surveillance monitoring by the operator or for use in machine vision applications.

traffic sensor control  (Existing and Planned)  Applicable ITS Standards

Information used to configure and control traffic sensor systems.

video surveillance control  (Planned)  Applicable ITS Standards

Information used to configure and control video surveillance systems.
