Caltrans D11 Field Equipment to Caltrans HQ Maintenance Administration Interface Diagram

Information Flow Definitions

field equipment status  (Existing)  

Reports from field equipment (sensors, signals, signs, controllers, etc.) which indicate current operational status.

roadway advisory radio data  (Existing)  

Information used to initialize, configure, and control roadside highway advisory radio. 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 advisory radio status  (Existing)  

Current operating status of highway advisory radios.

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.

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 image meta data  (Existing)  

Meta data that describes traffic images. Traffic images (video) are in another flow.

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.

vehicle signage application info  (Existing)  

In–vehicle signing application configuration data and messaging parameters. This flow provides a list of regulatory, warning, and information messages to be displayed and parameters that support scheduling and prioritizing messages to be issued to passing vehicles. This flow also supports remote control of the application so the application can be taken offline, reset, or restarted.

vehicle signage application status  (Existing)  

In–vehicle signing application status reported by the RSE. This includes current operational state and status of the RSE and a log of messages sent to passing vehicles.

video surveillance control  (Existing)  

Information used to configure and control video surveillance systems.
