Interface: St Louis County Traffic Operations Center - St. Louis County Traffic Field Equipment
Architecture Flow Definitions
rail crossing control data (Existing) Applicable ITS Standards
Data required for HRI information transmitted at railroad grade crossings and within railroad operations.
rail crossing request (Existing) Applicable ITS Standards
A request for highway–rail intersection status or a specific control request intended to modify HRI operation.
rail crossing status (Existing) Applicable ITS Standards
Status of the highway–rail intersection equipment including both the current state or mode of operation and the current equipment condition.
right-of-way request notification (Planned) Applicable ITS Standards
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 (Planned) 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 (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.
traffic detector control (Planned) Applicable ITS Standards
Information used to configure and control traffic detector systems such as inductive loop detectors and machine vision sensors.
traffic detector data (Planned) Applicable ITS Standards
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 sensor system.
video surveillance control (Planned) Applicable ITS Standards
Information used to configure and control video surveillance systems.
