The problems of airport landside capacity are of industry-wide interest. Evaluation of landside capacity enables airport operators and designers to identify passenger and baggage flows bottlenecks, find the primary cause of the bottlenecks formation and take measures mitigating the impact of bottlenecks on the airport operations. Many studies dealing with these problems are focused on the processing part of the airport terminal and consider the airport terminal to be an isolated system. Although this approach provides valuable data concerning capacity, delays or processing bottlenecks, in some cases, identified capacity constraints are only the symptoms of the actual problem. In order to identify the cause of the problem, it is necessary to consider the airport terminal as an integral part of much more complex regional or national transportation system. This book investigates the interrelationship between traffic flows within airport''s catchment area and passenger and baggage flows within the airport terminal with a view to improve the airport landside infrastructure utilisation and reduce the air pollution resulting from the high share of individual airport ground access trips.
