-
67 -
This is an SAE Motor Vehicle Council draft document of the DSRC committee, subject to change.
-- we could put out one UTC time, then offset from it?
-- Damlr still wants count-down timers, so kept as is
-- untill this is settled for good.
stateConfidence StateConfidence OPTIONAL,
-- Yellow phase time intervals
-- (used for motorised vehicle lanes and pedestrian lanes)
-- For the yellow Signal State, you may CHOICE one of the below:
yellState SignalLightState OPTIONAL,
-- the next state of a
-- Motorised lane
yellPedState PedestrianSignalState OPTIONAL,
-- the next state of a
-- Pedestrian type lane
yellTimeToChange TimeToChange OPTIONAL,
yellStateConfidence StateConfidence OPTIONAL,
-- below items are all optinal based on use and context
-- some are used only for ped lans
vehicleCount INTEGER (0..60000) OPTIONAL,
pedDetect PedestrianDetect OPTIONAL,
-- true if ANY ped are detected crossing
-- the above lanes
pedCount INTEGER (0..60000) OPTIONAL,
-- est count of peds
... -- # LOCAL_CONTENT
