From July 1974 through June 1977, the Double Deck Bus (DDB) Demonstration Project was conducted in New York City and in Los Angeles. The primary objective at the two sites was to assess potential increase in vehicle productivity in a feeder/park-and-ride-express busway service (L.A.) and in local service (NYC). Double deck buses carry from 68 to 85 passengers as contrasted with conventional buses which carry from 45 to 47 passengers. Both buses call for only a single transit employee, the driver. This report provides a comparative evaluation between the eight British Leyland double deck buses and four conventional GM buses in New York. Volume I contains and executive summary of both projects, while Volume III provides a detailed analysis of the double deck bus demonstration in Los Angeles. Bus routes in New York were characterized by congested traffic, heavy passenger loads, frequent stops, and frequent passenger turnover. A full-range of socio-economic classes was served and the routes traversed lower- to upper middle-class residential districts, major shopping centers and commercial and business areas. Only seven months of revenue service data are analyzed in this report, due to delays in manufacturing and in satisfying United States safety and environmental requirements. The evaluation considers passenger (including transit dependent) acceptance and perceptions of the DDB when compared with the conventional bus. Drivers, mechanics, and dispatchers were interviewed to identify their reactions to the new bus. Statistics are presentd on schedule adherence, dwell times, passenger throughput, vehicle reliability, on-board safety, fuel and oil consumption rates, operating costs, and financial and scheduling implications. Problems encountered in introducing a non production-line vehicle into revenue service in an existing fleet are discussed.
