Intercity travel in a university town like IIT Bombay is important for economic growth. The study looked at how people there choose to travel to other cities, focusing on air travel. They found that people's travel choices are influenced by their income and the mode of transportation available. People with higher incomes tend to fly more often and prefer comfortable modes of travel. The study used surveys to understand how people make decisions about airport choice and mode of transportation. The results show that travel behavior is not random but depends on both the mode of travel and the traveler's income level.
