Analysis of Routes and Ridership of a Franchised Bus Service: Green Bus Lines (Revised).

摘要

New York City Department of Transportation (NYCDPT) subsidizes several franchise bus operators in Queens and Brooklyn. The Franchise operators, which started operating in the first half of the Twentieth Century, have made few changes to their routes in the past several decades despite the changes in the neighborhoods that their routes serve; for example, new shopping areas developing, neighborhoods that gentrify or degenerate, exodus of industry. To add to these typical changes, Metrocard was implemented in 1997. The free transfers between bus and subway have led to major increases in ridership and probable shifts in origins and destinations to take advantage of the free transfer. At the same time, the fareboxes installed to handle Metrocard were supposed to provide detailed ridership counts and fare revenue information. However, the computer outputs from the fareboxes have obvious errors, for example, 16,000 passengers on one run. The lack of reliability of the data prevent analysis of the routes through the computer data.
