👉 Passenger math is a fundamental concept in economics that describes how individuals decide whether to travel based on the perceived benefits and costs of transportation. It involves a cost-benefit analysis where passengers weigh the monetary expenses (like ticket prices) against the utility or satisfaction derived from travel, such as time saved, convenience, comfort, and even environmental factors. The decision hinges on whether the marginal benefit of traveling an additional unit (e.g., a short trip) outweighs the marginal cost. This analysis helps explain why people choose different modes of transport, routes, and travel times, often leading to a balance between personal preferences and economic constraints.
