Interface: ADOT ITS Field Equipment - ADOT Systems Maintenance
Information Flow Definitions
environmental sensor control (Planned) Selected Comm Solution
Data used to configure and control environmental sensors.
environmental sensor data (Planned) Selected Comm Solution
Current road conditions (e.g., surface temperature, subsurface temperature, moisture, icing, treatment status) and surface weather conditions (e.g., air temperature, wind speed, precipitation, visibility) as measured and reported by fixed and/or mobile environmental sensors. Operational status of the sensors is also included.
field equipment status (Existing) Selected Comm Solution
Reports from field equipment (sensors, signals, signs, controllers, etc.) which indicate current operational status.
roadway dynamic signage data (Existing) Selected Comm Solution
Information used to initialize, configure, and control dynamic message signs. 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 devices.
roadway dynamic signage status (Existing) Selected Comm Solution
Current operating status of dynamic message signs.
roadway treatment system control (Planned) Selected Comm Solution
Control data for remotely located, automated devices, that treat the road surface (e.g., de–icing applications).
roadway treatment system status (Planned) Selected Comm Solution
Current operational status of automated roadway treatment devices (e.g., anti–icing systems).
signal control commands (Existing)
Control of traffic signal controllers or field masters including clock synchronization.
signal control device configuration (Existing)
Data used to configure traffic signal control equipment including local controllers and system masters.
signal control plans (Existing)
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)
Operational and status data of traffic signal control equipment including operating condition and current indications.
signal fault data (Existing)
Faults reported by traffic signal control equipment.
signal system configuration (Existing)
Data used to configure traffic signal systems including configuring control sections and mode of operation (time based or traffic responsive).
speed monitoring control (Planned) Selected Comm Solution
Information used to configure and control automated speed monitoring, speed warning, and speed enforcement systems.
speed monitoring information (Planned) Selected Comm Solution
System status including current operational state and logged information including measured speeds, warning messages displayed, and violation records.
traffic detector data (Existing)
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)
High fidelity, real–time traffic images suitable for surveillance monitoring by the operator or for use in machine vision applications. This flow includes the images. Meta data that describes the images is contained in another flow.
video surveillance control (Existing) Selected Comm Solution
Information used to configure and control video surveillance systems.
work zone warning device control (Planned) Selected Comm Solution
Data used to configure and control work zone safety monitoring and warning devices.
work zone warning status (Planned) Selected Comm Solution
Status of a work zone safety monitoring and warning devices. This flow documents system activations and includes additional supporting information (e.g., an image) that allows verification of the alarm.
