Transport Analysis

The document describes a methodology for calculating transport energy consumption based on vehicle stocks, annual mileage, and fuel economy. It explains how the LEAP software handles base year stocks, future projections, and lifecycle profiles to determine overall energy and environmental impacts, noting that this specific method allows for emission factors to be specified per unit of distance traveled.

• Energy consumption in the Transport Analysis methodology is determined by the product of the vehicle stock, the average annual distance traveled, and the fuel economy.
• The system calculates base year vehicle stocks either through direct entry or by using historical sales data combined with a lifecycle profile that tracks survival rates as vehicles age.
• The Transport Analysis method differs from other demand analysis methods by allowing emission factors to be defined per unit of distance traveled (e.g., grammes/veh-mile) rather than only per unit of energy consumed.
