(1) A HMI through which the Un/Loading Zone Operator can manage the use of parking places in loading or unloading zones and their associated holding zones.
(2) The HMI shall enable the Un/Loading Zone Operator to confirm booking requests, plus obtain and update data about the zones.
(3) If an incorrect Freight Vehicle is found to be using a parking place, the ability for the HMI to output information about the Vehicle to the Un/Loading Zone Operator.

Functional Requirements

(a) continuously monitor for receipt of the un/loading zone request and incorrect vehicle in un/loading zone from the Manage Loading or Unloading Zone Bookings function or the data flow containing a request current in/loading zone data and current un/loading zone data update from the parking zone operator
(b) when the first data flow in (a) is received, output the request to the un/loading zone operator in the un/loading zone use request data flow and continuously monitor for the response in the un/loading zone use response data flow
(c) when the data flow in (b) is received, pass on its contents to the Manage Loading or Unloading Zone Bookings function in the un/loading zone use response data flow
(d) when the second data flow in (a) is received, output the vehicle identity to the un/loading zone operator in the incorrect vehicle in un/loading zone data flow
(e) when the third data flow is received in (a) send the request to the Manage Store of Loading or Unloading Zone Use function in the data flow expected to contain the request un/loading zone data and continuously monitor for the receipt of the data flow containing the requested un/loading zone data
(f) when the data flow in (e) is received, output its contents to the un/loading zone operator in the data flow containing current un/loading zone data
(g) when the fourth data flow is received in (a), send the updates to the zone data to the Manage Store of Loading or Unloading Zone Use function in the data flow containing updated un/loading zone data.
