Interface: ADOT Maintenance Work Zone Field Equipment - ADOT Roadside Comm Equipment
Architecture Flow Definitions
field equipment commands (Existing) Applicable ITS Standards
System-level control commands issued to field equipment such as reset and remote diagnostics.
field equipment configuration settings (Existing) Applicable ITS Standards
Control settings and parameters that are used to configure field equipment.
field equipment software install/upgrade (Existing) Applicable ITS Standards
This flow supports installation and update of software residing in ITS roadway equipment. It supports download of the software installation files, including executable code and associated support files.
field equipment status (Existing) Applicable ITS Standards
Reports from field equipment (sensors, signals, signs, controllers, etc.) which indicate current operational status.
roadway dynamic signage 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). 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 dynamic signage status (Planned) Applicable ITS Standards
Current operating status of dynamic message signs, highway advisory radios, or other configurable field equipment that provides dynamic information to the driver.
roadway equipment coordination (Existing)
The direct flow of information between field equipment. This includes transfer of information between sensors and driver information systems (e.g., DMS, HAR, variable speed limit signs, dynamic lane signs) or control devices (e.g., traffic signals, ramp meters), direct coordination between adjacent control devices, interfaces between detection and warning or alarm systems, and any other direct communications between field equipment.
traffic situation data (Planned) Applicable ITS Standards
Current, aggregate traffic data collected from connected vehicles that can be used to supplement or replace information collected by roadside traffic detectors. It includes raw and/or processed reported vehicle speeds, counts, and other derived measures. Raw and/or filtered vehicle control events may also be included to support incident detection.
vehicle signage local data (Planned) Applicable ITS Standards
Information provided by adjacent field equipment to support in-vehicle signing of dynamic information that is currently being displayed to passing drivers. This includes the dynamic information (e.g., current signal states, grade crossing information, local traffic and road conditions, detours, advisories, parking availability, etc.) and control parameters that identify the desired timing, duration, and priority of the signage data.
work zone warning notification (Planned) Applicable ITS Standards
Notification of a work zone emergency or safety issue. This flow identifies that a work zone emergency or safety issue has occurred so that warnings may be generated by more than one system in the work zone.
