Mass Transit - Center for Transportation and the Environment released updated guidance for ZEB resiliency

September 15, 2025

The Center for Transportation and the Environment (CTE) released the Transit Cooperative Research Program (TCRP) Research Report 256: Resilient Zero-Emission Transit Bus Fleets: A Guide. The guidebook, developed by CTE under the Transportation Research Board’s TCRP, provides strategies for updating existing emergency response and resilience plans to incorporate zero-emission bus (ZEB) technologies for transit agencies.

According to the guidebook, the shift to zero-emission technologies requires transit agencies to make changes in operations management to accommodate the unique characteristics of these technologies. For example, the need to charge buses means agencies are increasingly reliant on electrical power grids. The guidebook provides a step-by-step approach to adapt existing resilience plans, originally designed for internal combustion engine fleets, to the requirements of ZEBs. This framework guides agencies through assessing potential threats, evaluating risks and implementing cost-effective resilience strategies.
