META-CDM : Multimodal, Efficient Transportation in Airports and Collaborative Decision Making

Be it snow, volcanic ash or strikes, crisis events impose high costs on the air transportation system and society. Airlines have progressively learned to mitigate the irregular operations arising from such events through procedures such as Airport Collaborative Decision Making (A-CDM) for traffic flow and airport departure management; however the passenger's door-to-door journey during difficult times often remains unpleasant. Meta-CDM (Multimodal, Efficient Transportation in Airports and Collaborative Decision Making), aims to take a passenger-centric approach and to examine how airside and landside CDM can be interlinked with other transport modes to minimize the impact of severe disruptions. We provide an analysis of past successes and failures of passenger-centric operations, by investigating representative disruptive events. We focus on the links between different transportation modes and the practicalities of switching modes in a crisis situation. We analyze if and how passenger metrics could be used to measure the performance of an extended A-CDM concept.
