For transit operators with zero-emission buses (ZEBs) in their fleets, the primary concern is whether the vehicles can meet the agency’s service requirements for both regularly scheduled service and for unscheduled service to address local or regional events and emergencies. This concern applies both at the individual route and fleet levels.
TCRP Research Report 256: Resilient Zero-Emission Transit Bus Fleets: A Guide, from TRB's Transit Cooperative Research Program, provides a framework for transit agencies to update their resilience plans to operate ZEB fleets. It also offers a roadmap for transit agencies to integrate their existing zero-emission vehicle (ZEV) transition strategies into broader resilience planning efforts.
