This dataset represents freight transport services provided by trucks with a gross weight >26t and emission standard China V, carrying 1 ton of cargo over a distance of 1 kilometer. The transportation dataset covers the entire life cycle of transportation, including the construction, operation, maintenance, and end-of-life of vehicles and highway infrastructure.
The average cargo load for this heavy-duty Class III truck is 46 tons, with an average load factor of 60%, values derived from references on truck fuel consumption and the 'China Road Freight Big Data Carbon Emissions Report'. Fuel consumption and major emissions (nitrogen oxides, nitrous oxide, methane, non-methane hydrocarbons, ammonia, benzene, and lead) are calculated based on fuel consumption limits for operational diesel trucks specified in Chinese standards and literature.
Truck size and load factor determine the GVW, and thus influence fuel consumption and exhaust as well as non-exhaust emissions. Exhaust emissions from fuel combustion depend on the fuel (fuel type and quantity) or on the emission stage. The latter reflects the emission regulations to which the vehicle conforms. For highway infrastructure, expenditures and environmental impacts resulting from highway construction are allocated based on total ton-kilometer performance. Expenditures for highway infrastructure operation and land use have been allocated based on annual vehicle kilometers traveled.
