Couverture des transports en commun, aéroports et qualité des infrastructures pour les expatriés

The Northern Mariana Islands (CNMI), a U.S. commonwealth with 57,557 residents across islands like Saipan, Tinian, and Rota, features a transportation landscape dominated by private vehicles, taxis, and emerging public transit due to its remote Pacific location. Key strengths include 12 airports with 3 major ones providing essential air connectivity, while challenges involve limited inter-island options, reliance on imports, and vulnerability to typhoons. The Commonwealth Office of Transit Authority (COTA) operates demand-responsive and fixed-route services on Saipan, supported by federal funding. Residents and visitors rely on cars (right-side driving), air travel, and planned ferries for mobility.
