Definitions

  • the present invention relates generally to the managing of entities in a physical space.

  • the working conditions of these classes of individuals are affected by current technological trends, and furthermore significant convergence of their roles.
  • vehicles are increasingly autonomous, so that the role of the driver or pilot is increasingly supported by electronic tools such as navigation tools, and/or entrusted to a remote operator who can take over control of the vehicle via a telecommunications channel at critical instants.
  • supervision and guidance tasks may be increasingly supported by information technology, so that one individual can be expected to supervise an ever larger area, or increasingly, to supervise several different areas, or attribute only a portion of their attention to traffic considerations, with the relevant traffic information being relayed from the respective areas via telecommunications means.

  • the method comprises the further steps of receiving a user input specifying a new position of the indication on the path, a modification of the path which would modify the predicted time of arrival of the mobile entity to correspond to the new position of the indication, and issuing a communication to the mobile entity indicating the variations.
