Samenvatting
When the Ottawa Transportation Commission converted in 1958 from streetcars, trolley coaches and buses to an all-bus operation, specifications have were prepared and tenders were requested for 107 buses. The tenders received were evaluated on the basis of initial cost, availability, reliability, and operating and maintenance cost. Bus appearance, comfort, driver and passenger appeal, service and delivery were considered as important intangibles. Project cost curves are illustrated and the establishment of relative costs is explained.
