Distance-based and flat fare structures

Description

Distance-based and flat fare structures are two foundational approaches to pricing public transit. A flat fare is described as "the simplest fare structure," charging "a fixed price for a given service." A prominent modern example is the Los Angeles Metro, which "charges $1.75 for a standard single ride on its buses or rail services." A flat fee may cover a single ride or "an unlimited number of rides within a single time period such as 90 minutes, a day or a week." Distance-based fares, by contrast, charge passengers according to "the distance traveled between the origin and destination stations or stops of a service." To accurately bill customers, such systems often employ an exit fare mechanism at the destination station "in order to correctly charge the customer based on the distance traveled." Cited examples of distance-based systems include the Beijing Subway and San Francisco Bay Area's BART system. Both structures exist within a broader ecosystem of fare types. Transit fares generally serve as "a contribution to the operational costs of the transport system involved, either partial... or total," with farebox recovery ratios "typically vary[ing] from 30%–60% in North America and Europe, with some rail systems in Asia over 100%." Other fare structures—including zone-based, transfer, subscription, and variable fares—complement flat and distance-based models in modern public transport networks.[1,2,3,4,5]

    Some transportation systems charge a fare based on the distance traveled between the origin and destination stations or stops of a service. Such a system may use an exit fare at the destination station in order to correctly charge the customer based on the distance traveled.

    The fare paid is a contribution to the operational costs of the transport system involved, either partial (as is frequently the case with publicly supported systems) or total. The portion of operating costs covered by fares - the farebox recovery ratio - typically varies from 30%-60% in North America and Europe, with some rail systems in Asia over 100%.
