Because of growing concerns about the future environmental impact of passenger travel, modal energy efficiency is becoming increasingly important when benefits and costs of transportation system investment are evaluated. Because passenger rail systems are often cited as being relatively more energy efficient than other modes, reduced environmental impact is one justification for investment in new commuter rail projects. It is important that studies of purported environmental benefits analyze…

Accommodation of Long-Term Growth on North America's Commuter Railroads

The transit industry has experienced great declines in ridership since World War II from which it has recovered only partially since the 1990s. By contrast, commuter rail has flourished as a result

Factors affecting urban transit ridership

The use of urban public transit services (buses, urban rail, subways and streetcars) in Canada grew steadily in the seventies and eighties, reaching a peak of 1.53 billion passengers in 1990.
