trials and demonstrations Connection to real-time operational A-SMGCS Level 2

7 Airport Research Facility Hamburg Cooperation with DFS and Airport Hamburg (common research agenda) Two special equipped rooms for development, field trials and demonstrations Connection to real-time operational A-SMGCS Level 2 data and airport database Usable for A-SMGCS and Total Airport Management (TAM) research Slide 7

8 Look Back (vehicle scheduling) ATM Seminar 2009 ( AIRPORT SERVICE VEHICLE SCHEDULING ) Investigation of various algorithms for scheduling airport service vehicles Simulation runs for bus scheduling at Hamburg Airport and Dallas Fort Worth Results showed benefit in delay reduction and vehicle travel distances Slide 8

9 Vehicle Management System Concept Slide 9

10 Main Concept Ideas Use of data link for dispatcher/driver communication Automatic recording of time stamps during the handling process Support of resource selection by providing an optimization module Providing a traffic situation to driver and dispatcher Reduction of number of information systems (monitors) Easy drag and drop operation and reduced workload Providing status information of task execution Slide 10

17 Ground System (HMI) Traffic Situation Position and identification (equipped vehicles and aircraft) Management Status information (flights, resources, tasks) Task assignment (drag and drop) Bidirectional communication between displays (coupling of information) Slide 17

18 Ground System (management interface) Vehicle resources Tasks Flight plan Details Traffic load Slide 18

19 Ground System (support systems / infrastructure) Secured virtual wireless Network within the existing WLAN at Hamburg airport Interface components to the A-SMGCS and the operational airport database Database Communication server (centralized communication between onboard and ground) Situation server (fusion of position information from vehicles and aircraft) Optimizer (processing of interactions of dispatcher and driver, scheduling) Slide 19

20 Vehicle Management System Summary Slide 20

21 Field Trials Quality and coverage of the wireless infrastructure Long term measurements on board of a follow me car TUHH Position calculation with additional vehicle sensors Test runs with a special equipped vehicle TU-BS Overall Prototype system 2 weeks trial period Main focus - technical verification 2 test vehicles, 15 equipped luggage cars Dispatcher station besides the operational workplace Slide 21

22 Results Quality and coverage of the wireless infrastructure good Use of GPS possible better results and indoor navigation with additional sensors Connection to operational systems successful Proof of the overall system concept First feedback positive especially from dispatchers but Proof of operational benefits still missing simulator trials Slide 22

23 Outlook Improved dispatcher system Integrated solution (one display) Using the Eurocontrol Early Demonstration & Evaluation Platform (edep) as a base Integration into a Total Airport Management concept Slide 23
