Interface: TTI Field Equipment To TTI TransLink

environmental conditions data   (Existing)  

Current road conditions (e.g., surface temperature, subsurface temperature, moisture, icing, treatment status) and surface weather conditions (e.g., air temperature, wind speed, precipitation, visibility) as measured and reported by environmental sensors.

 

environmental sensors control   (Existing)  

Data used to configure and control environmental sensors.

 

hri control data   (Existing)  

Data required for HRI information transmitted at railroad grade crossings and within railroad operations.

 

railroad network video and data_ud   (Existing)  

Real-time video and train information for highway rail intersections. Data includes train location, speed and direction.

 

reversible lane status   (Future)  

Current reversible lane status including traffic sensor and surveillance data and the operational status and mode of the reversible lane control equipment.

 

signal control data   (Future)  

Information used to configure and control traffic signal systems.

 

signal control status   (Future)  

Status of surface street signal controls.

 

traffic flow   (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).

 

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 and the operational status of the surveillance system.

 

traffic sensor control   (Existing)  

Information used to configure and control traffic sensor systems.

 

video surveillance control   (Existing)  

Information used to configure and control video surveillance systems.
