Interface: County ITS Field Equipment - MTS Wayside Equipment
Information Flow Definitions
advisory radio coordination (Planned)
The direct flow of information between field equipment. This includes information used to initialize, configure, and control roadside highway advisory radio including 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 monitoring and management of these systems.
dynamic sign coordination (Planned)
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.
local priority request coordination (Planned)
The direct flow of information between field equipment. This includes notification of crossing calls from pedestrians and other vulnerable road users and requests for signal prioritization or preemption, and any other request for right–of–way at an intersection. The status of the priority request is also shared. For vulnerable road users, this includes information provided to guide and warn vulnerable road users at crossings including crossing permission status and crossing time remaining.
passive vehicle monitoring coordination (Planned)
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.
signal control coordination (Planned)
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)
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
video surveillance coordination (Planned)
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.
