Planning Deployment of Zero-Emission Bus for Williamsburg Area Transit Authority (WATA)

Planning Deployment of Zero-Emission Bus for Williamsburg Area Transit Authority (WATA)

In the US in 2020, the transportation sector was responsible for 27% of the greenhouse gas (GHG) emissions (US EPA, 2020). Alternative fuels such as compressed natural gas (CNG) and liquid natural gas (LNG) were one of the approaches to addressing urban air quality degradation until the emergence of electric powertrains.

WATA obtained funds from the Congestion Mitigation and Air Quality (CMAQ) federal program (allocated by HRTPO), with which they plan to purchase one 35-foot zero-emission bus and deploy it on one of WATA’s routes.

HRTPO staff conducted a study to assist WATA in deploying the ZEB. As part of this effort, the HRTPO staff reviewed ZEB deployments across transit agencies in Virginia and summarized their experience and recommendations. Additionally, the staff analyzed the technology and costs associated with ZEB deployment and researched the best practices and recommendations for training. To further assist WATA, the HRTPO staff assessed factors affecting route choice and analyzed the best route for ZEB deployment. The full version of the report can be accessed HERE.
