National Summary Statistics for Depot-Based Medium and Heavy-Duty Vehicle Operations

Delivering nationally aggregated summary statistics characterizing daily operations for medium- and heavy-duty vehicles, including transit and school buses. It includes typical daily driving distances, domicile dwell durations, and potential normalized electric vehicle depot charging load curves. The data is designed for national representativeness and analysis.

Use Cases

• Model potential normalized electric vehicle depot charging load curves based on vehicle operating patterns.
• Analyze typical daily driving distances for depot-centric vocational trucks to inform fleet electrification planning.
• Study domicile dwell durations for transit buses and school buses to assess depot charging infrastructure needs.
• Characterize the subset of medium and heavy duty vehicle operating patterns that originate from a consistent depot each day.

Strengths

• Data is designed with national representativeness in mind, suitable for national analysis.
• Covers multiple vehicle types including trucks, transit buses, and school buses.
• Associated methodology is detailed in a published NREL technical report.

Limitations

• Specific data volume (rows, columns) and granularity are unknown.
• Data is aggregated to national summary statistics, limiting regional or local analysis.
• Primary file formats are PDF and BIN, which may require specific tools for data extraction and analysis.
