Passenger transportation, whether on land, over the water, or in the air is the lifeblood of the tourism industry. Water transportation was the first mode of transportation to move travelers rapidly over long distances, but many other modes have evolved to meet time and distance requirements.Travelers have the choice of plying the waves, riding the rails, cruising the highways, or soaring through the skies. Which one they choose will depend on where they are going, their budget, and the amount of flexibility they desire.
