In geographic and cartographic analyses of transportation networks, fuel efficiency is a key metric for assessing environmental impact and economic viability. Measuring fuel consumption relative to the mass moved and the distance covered provides a more nuanced view than simple mileage figures.
The unit ton‑kilometer (tkm) combines the weight of a vehicle (in tons) with the distance it travels (in kilometers). This composite metric is widely used in logistics, regional planning, and sustainability studies to compare the performance of different transport modes and routes.
By relating total fuel used to the product of vehicle weight and distance, analysts can derive the fuel consumption per ton‑kilometer, a figure that directly reflects how efficiently a vehicle moves mass over space.
