Traffic at Wonderland airport (WAX) has increased drastically over the past few years. The increase in the number of companies and flights calls for the building of new terminals. The increase in the number of passengers calls fora new transportation system between all terminals, and between the main terminal and Wonderland City. The current bus transportation system has reached its limits in terms of transportation capacity and quality of service. Buses are slow and often late due to traffic jams; passengers need to stand in long queues, sometimes for an unacceptably long time, which may cause them to miss flight connections, and so on.
