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.
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.
