Interface: ADOT Systems Maintenance - ADOT Maintenance Work Zone Field Equipment
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).
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.
vehicle signage application info (Planned) Selected Comm Solution
In–vehicle signing application configuration data and messaging parameters. This flow provides a list of regulatory, warning, and information messages to be displayed and parameters that support scheduling and prioritizing messages to be issued to passing vehicles. This flow also supports remote control of the application so the application can be taken offline, reset, or restarted.
vehicle signage application status (Planned) Selected Comm Solution
In–vehicle signing application status reported by the RSE. This includes current operational state and status of the RSE and a log of messages sent to passing vehicles.
video surveillance control (Planned) Selected Comm Solution
Information used to configure and control video surveillance systems.
work zone safety application info (Planned) Selected Comm Solution
Work zone safety application configuration data and warning parameters and thresholds. This includes work zone configuration including geofenced crew areas and travel lanes that provide a safety boundary between work zone personnel and passing vehicles. This flow also supports remote control of the application so the application can be taken offline, reset, or restarted.
work zone safety application status (Planned) Selected Comm Solution
Work zone safety application status reported by the RSE. This includes current operational state and status of the RSE and a record of identified work zone safety alerts and warnings issued.
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.
