CIVIL AERONAUTICS BOARD Domestic common carrier intercity passenger travel market scheduled and nonscheduled services of airlines, buses, railroads, and water ways, 1951-63

[Millions of passenger-miles)

[merged small][merged small][merged small][ocr errors][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small]

1 ICC data 1957-62. National Association of Motor Bus Operators (NAMBO) data 1951-56. To make
the data for 1951-56 comparable with data for 1957-62, NAMBO estimated the former years by applying a
certain percentage to existing ICC data for those years.
2 Electric railway figures are estimated by ICC.

NOTE.--Airlines: Domestic operations of certificated route and supplemental air carriers. Helicopter, intra-Alaska, and intra-Hawaii carriers are excluded.

Buses: Regular-route, charter, and special-service travel in revenue service on both interstate and intrastate schedules; schoolbus travel not included. Commutation traffic is excluded.

Railroads: All classes, including electric railways. Commutation traffic is excluded.
Waterways: Inland and coastal waterways.

Source: Form 41 and other reports to the CAB; Interstate Commerce Commission; and National Associa.
tion of Motor Bus Operators.
