This dataset represents freight transport services provided by trucks with a payload capacity of <=1.8 tons and China IV emission standard, transporting 1 ton of cargo over a distance of 1 kilometer. The transport 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 of this micro truck is 1. 2 tons, with an average load factor of 60%; these values are referenced from the fuel consumption of freight trucks in literature and the "China Highway Freight Big Data Carbon Emission Report".
Fuel consumption and major emissions (nitrogen oxides, nitrous oxide, methane, non-methane hydrocarbons, ammonia, benzene, and lead) are calculated based on China's standards and fuel consumption limits for operational diesel freight trucks cited in the literature.
Truck size and load factor determine the GVW, and thus also influence fuel consumption and exhaust and non-exhaust emissions. Exhaust emissions from fuel combustion depend on the fuel (fuel type and quantity) or on the emission standard level. The latter reflects the emission regulations that the vehicle complies with. For highway infrastructure, expenditures and environmental interventions resulting from highway construction are allocated based on total ton-kilometer performance. Costs related to highway infrastructure operation and land use are allocated based on annual vehicle kilometers traveled.
