Interface: Local Roadway Devices - Local Traffic Management Center
Information Flow Definitions
right-of-way request notification (Existing)
Notice that a request has occurred for signal prioritization, signal preemption, pedestrian call, multi–modal crossing activation, or other source for right–of–way.
roadway dynamic signage data (Existing)
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)
Current operating status of dynamic message signs.
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 control status (Existing)
Operational and status data of traffic signal control equipment including operating condition and current indications.
signal fault data (Existing)
Faults reported by traffic signal control equipment.
signal system configuration (Existing)
Data used to configure traffic signal systems including configuring control sections and mode of operation (time based or traffic responsive).
traffic detector control (Existing)
Information used to configure and control traffic detector systems such as inductive loop detectors and machine vision sensors.
traffic detector data (Existing)
Raw and/or processed traffic detector data which 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
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.
video surveillance control (Existing)
Information used to configure and control video surveillance systems.
