Interface: St Charles County Traffic Signal - St Charles County Gateway Green Light System
Architecture Flow Definitions
roadway dynamic signage data (Existing) Applicable ITS Standards
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 systems.
roadway dynamic signage status (Existing) 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.
signal control commands (Existing) Applicable ITS Standards
Control of traffic signal controllers or field masters including clock synchronization.
signal control data (Existing)
Information used to configure local traffic signal controllers.
signal control plans (Existing) Applicable ITS Standards
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) Applicable ITS Standards
Operational and status data of traffic signal control equipment including operating condition and current indications.
signal system configuration (Existing) Applicable ITS Standards
Data used to configure traffic signal systems including configuring control sections and mode of operation (time based or traffic responsive).
