environmental conditions data
(Future)
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
(Future)
Data used to configure and control environmental sensors.
freeway control data
(Future)
Control commands and operating parameters for ramp meters, mainline metering/lane controls and other systems associated with freeway operations.
freeway control status
(Future)
Current operational status and operating parameters for ramp meters, mainline metering/lane controls and other control equipment associated with freeway operations.
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 sensor control
(Existing)
Information used to configure and control traffic sensor systems.
vehicle probe data
(Future)
Vehicle probe data indicating identity, route segment identity, link time and location.
