Transport Analysis Calculations

The document details the calculations for transport analysis, focusing on how vehicle stock is tracked by vintage and how fuel economy, mileage, and emissions degrade over a vehicle's lifecycle. It specifies that stock is determined by sales and survival profiles, while energy and pollutant emissions are calculated based on distance traveled and age-related degradation factors.

• Vehicle stock is calculated based on the number of vehicles added in a specific year (sales) multiplied by a survival fraction derived from a lifecycle profile, with a maximum vintage tracking period of 30 years.
• Energy consumption and distance-based pollution emissions are calculated by incorporating degradation factors that represent how fuel economy, mileage, and emission rates change as a vehicle ages from its model year.
