Interface: ADOT Roadside Comm Equipment - ADOT DUST Detection System
Information Flow Definitions
dynamic sign coordination (Existing) Selected Comm Solution
The direct flow of information between field equipment. This includes 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 local management of these devices. Current operating status of dynamic message signs is returned.
environmental sensor coordination (Existing) Selected Comm Solution
The direct flow of information between field equipment. This includes configuration and control of environmental sensors and the 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.
passive vehicle monitoring coordination (Planned) Selected Comm Solution
The direct flow of information between field equipment. This includes control commands used to control detection systems that rely on infrastructure–based identification of individual vehicles to measure travel times and other related measures by identifying the same vehicle at different points in the network. Related technologies include Bluetooth readers and license plate recognition systems. The coordination also includes sharing of time stamped identifiers that identify the vehicles that have passed through a detection zone.
roadway warning coordination (Existing) Selected Comm Solution
The direct flow of information between field equipment. This includes information used to configure and control roadway warning systems and the current operating status of roadway warning systems.
signal control coordination (Planned) Selected Comm Solution
The direct flow of information between field equipment. This includes configuration and control of traffic signal controllers or field masters. Configuration data and operational status of traffic signal control equipment including operating condition and current indications are returned.
traffic detector coordination (Planned) Selected Comm Solution
The direct flow of information between field equipment. This includes information used to configure and control traffic detector systems such as inductive loop detectors and machine vision sensors Raw and/or processed traffic detector data is returned that 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
variable speed limit coordination (Existing) Selected Comm Solution
The direct flow of information between field equipment. This includes information used to configure, control, and monitor variable speed limit systems including the equipment used to provide current speed limits and other information to drivers.
video surveillance coordination (Planned) Selected Comm Solution
The direct flow of information between field equipment. This includes information used to configure and control video surveillance systems and the high fidelity, real–time traffic images and associated meta data that are returned.
