Just take the Metro Line #2 from Pudong airport to downtown Shanghai. This will replace taxi, maglev, and bus as the recommended transportation.
Transition still needed. Passengers need to get off the train at Guanglan Road Station 广兰路 and wait at the same platform to another train to downtown Shanghai. The reason is, the newly added stations don't have too many traffic. They use 4-cart train to operate on this segment, and the rest line uses 8-cart train.
