Interface: ADOT Systems Maintenance - ADOT Roadside Comm Equipment
Information Flow Definitions
environmental sensor control (Existing) Selected Comm Solution
Data used to configure and control environmental sensors.
environmental sensor data (Existing) 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 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 system configuration (Existing)
Data used to configure traffic signal systems including configuring control sections and mode of operation (time based or traffic responsive).
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.
