Aims• Compute the value of additional slots at
congested airports• Analyzing 30 busiest airports in United States and Europe
• Need to balance:• capacity utilization • delays
• Administrative systems:• US based on first come first served principle• Europe based on slot allocation & grandfather rights
ATM & Delay• The aviation system is a queuing system & as demand hits
capacity the delays increase non-linearly• Odoni et al. (2010) measured the value of delay in the US for
2007:

Scheduling based on VFR or IFR?

Capacity Utilization versus Delays
• US: airline schedules based on VFR & high capacity utilization therefore high level of delays
• Europe: airline schedules based on slot allocations based on IFR & low capacity utilization therefore low levels of delay
• estimate connection between:– runway & terminal capacity – delays– profits for airports & airlines
• where is it worthwhile increasing capacity & how much is an extra movement worth?

Conclusions• Airside greater impact on throughput than landside• Slot allocations limit volume hence reduce delays
(excessively)• In Europe: worthwhile increasing slots because value
of additional slot exceeds additional cost of delay• Questions to be considered in second part of project:
– Passenger viewpoint (schedule versus real delay)– Safety– Environmental externalities
