For the New York Power Authority MJB&A developed and managed a test program to evaluate the performance of diesel hybrid-electric school buses compared to traditional diesel school buses with automatic transmissions. The program included 10 months of in-service operation at the Gates-Chili Central School district in Rochester, New York during the 2012-2013 school year, as well as fuel economy testing in simulated service on specific test routes intended to mimic urban, suburban, and rural school bus operation. The program also evaluated the in-service performance of a vehicle telematics system purported to increase vehicle fuel economy by promoting optimal transmission shifting using audible driver prompts. The final project report documents the details of the test program and the full results of the testing.
