Demonstration and Evaluation of Hybrid Diesel-Electric Transit Buses.

摘要

The project goal was to identify the next generation of transit vehicles for future fleet replacement that are cost effective, reliable, produce fewer emissions, and have improved fuel economy compared to the standard heavy-duty diesel powered bus. Data was collected to produce an estimated life-cycle cost analysis, emissions information, mileage, fuel economy, power production, brake pad wear, and maintenance and repair costs. Bus operator and Customer surveys were also performed. The 18 month project data collection effort was completed on December 31, 2004. The results found the hybrid buses to be very reliable and to achieve 10% better fuel economy than their comparable diesel buses. All vehicle emissions in the study were essentially the same. The hybrid buses had a lower life cycle cost when the current FTA 80% purchase subsidy was considered. The hybrid buses were rated very favorably by both the Bus Operators and Customers that rode in them.
