time_headway() unclear

8.7.5.1.2 Method time_headway()

Returns the time distance between a traffic participant and a reference physical_object.

Prototype

    extend vehicle:
        def time_headway(reference: physical_object) -> time

Return value

    Returns the time distance between traffic participant and reference physical_object, measured from reference point to reference point along s-coordinate, assuming the reference physical_object keeps moving with its current speed.

Example

my_vehicle.time_headway(other)

Questions:

  • What is meant as reference in the definition? The reference as named in the type signature or the object which method is called?
  • In example: Should my_vehicle maintain current speed in calculation?
  • In example: Should other maintain current speed in calculation?
