TDOT Region 2 TMC - Chattanooga to TDOT Ramp Metering Equipment Interface Diagram

Architecture Flow Definitions

freeway control data  (Planned)  Applicable ITS Standards

Control commands and operating parameters for ramp meters, mainline metering/lane controls and other systems associated with freeway operations.

freeway control status  (Planned)  Applicable ITS Standards

Current operational status and operating parameters for ramp meters, mainline metering/lane controls and other control equipment associated with freeway operations.

roadway information system 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, beacon systems). 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 information system status  (Planned)  Applicable ITS Standards

Current operating status of dynamic message signs, highway advisory radios, beacon systems, or other configurable field equipment that provides dynamic information to the driver.

traffic flow  (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 detectors.

traffic images  (Planned)  Applicable ITS Standards

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 and the operational status of the surveillance system.

traffic sensor control  (Planned)  Applicable ITS Standards

Information used to configure and control traffic sensor systems.

video surveillance control  (Planned)  Applicable ITS Standards

Information used to configure and control video surveillance systems.
