CORE · WIREDVolume / speed / occupancy detectors: lane-level counts and states from loops, radar and video detection.
Data model
The configuration and state tree. Safety constraints are expressed as YANG must and validated at every boundary.
container traffic-sensor {
list lanes {
key "index";
leaf index { type uint8; }
leaf volume { type uint32; units "veh"; }
leaf speed { type decimal64; units "km/h"; }
leaf occupancy { type decimal64; units "percent"; }
}
}
