Montgomery County, Maryland, is undertaking an ambitious transformation to convert its 400‑vehicle Ride On bus fleet to zero‑emission technologies by 2035. To support this landmark initiative, STV, working in partnership with the Montgomery County Department of Transportation (MCDOT), developed a comprehensive master plan that outlines the infrastructure, technology pathways, funding opportunities, and operational considerations required for a full transition. The plan establishes a flexible roadmap that accommodates emerging zero‑emission bus technologies while aligning with the county’s broader greenhouse gas reduction goals.
What challenges did STV address?
Montgomery County sought to drastically lower carbon emissions – 42% of which stem from the transportation sector – while maintaining reliable transit service for riders. Achieving a countywide zero‑emission fleet required addressing large‑scale operational, facility and energy challenges, including depot upgrades, charging/fueling strategies and integration of future technologies.
What solutions did STV deliver?
STV guided MCDOT through a full evaluation of fleet needs, depot modernization requirements, workforce implications and long‑term energy strategies. The master plan identifies infrastructure improvements for maintenance facilities, bus depots and fueling/charging systems while outlining state and federal grant opportunities – many of which the county successfully secured.
How does this project benefit the region?
The resulting plan serves as a blueprint for delivering cleaner, quieter transit service, reducing greenhouse gas emissions and supporting Maryland’s statewide sustainability commitments. By providing a structured, funded, and adaptable pathway, the project enhances local air quality and sets a replicable model for zero‑emission fleet transitions nationwide.
