time of generation

time when the content of the LDM data object information field was created
NOTE 1 to entry: This is different to the time when the LDM data object was written into an LDM.

traffic signal phase overload

proceed manoeuvre that has been terminated while demand for the manoeuvre continues
NOTE 1 to entry: Repeated phase overloads indicate that the signal phase timing is not adequate to satisfy the demand.

velocity

an object's speed and direction of motion
NOTE 1 to entry: Velocity is a physical vector quantity; both magnitude and direction are needed to define it.
The scalar absolute value (magnitude) of velocity is called speed, a unit whose quantity is measured in the
international system of units as metres per second (m/s).

work zone

area of a highway with construction, maintenance, or utility work activities
NOTE 1 to entry: A work zone is typically marked by signs, channelizing devices, barriers, pavement markings, and/or work vehicles.
NOTE 2 to entry: A work zone extends from the first warning sign or high-intensity rotating, flashing, oscillating, or strobe lights on a vehicle to the END ROAD WORK sign or the…
