The study conducted by the
Results of the 18-month testing showed that the hybrid buses demonstrated about 10% improved fuel economy compared to the base clean-diesel buses. The buses were popular among passengers and operators, who cited their quiet vibration-free ride. Despite the fact that these buses are of new design and are early in the product cycle, reliability performance of the hybrid buses met and exceeded expectations. Emissions for the hybrid buses and the comparison clean-diesel buses were found to be about the same; both were significantly cleaner than average emissions from older buses in the CTTRANSIT fleet.
The hybrid buses and comparison diesel buses underwent a three-phase in-depth test of fuel economy, reliability, maintenance expense and emissions. During the first phase of testing, the buses were run on the standard fuel for public transportation buses in
During the testing period, the two buses operated on regular routes in the
The demonstration and evaluation project was a collaboration of many organizations, including ConnDOT's Bureau of Public Transportation and Division of Research, the University of Connecticut, the Connecticut Academy of Science and Engineering, New Flyer Bus Company, Allison Electric Drive, Horiba Instruments, the East Coast Hybrid Consortium, and CTTRANSIT.
Results of the reports will be shared with the transit community with the hopes that, in conjunction with results of other testing projects, this study will assist both ConnDOT and the industry with future decision making. Follow-up studies are also recommended in the report, and the
