Description
This dataset represents freight trucks with a payload greater than 26 tonnes and meeting China IV emission standards providing one tonne-kilometre of transport service. The transport dataset covers the entire life cycle of transportation, including the construction, operation, maintenance, and end-of-life stages of vehicles and highway infrastructure.
The average freight load of this heavy-duty Class III truck is 46 tonnes, with an average load factor of 60%, values derived from references on truck fuel consumption and the 'China Road 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 fuel consumption limits for in-use diesel trucks according to Chinese standards and literature.
Truck size and load factor determine the Gross Vehicle Weight (GVW), and thus influence fuel consumption as well as exhaust and non-exhaust emissions. Exhaust emissions from fuel combustion depend either on the fuel (fuel type and quantity) or on the emission stage, which reflects the emission regulations the vehicle complies with. For highway infrastructure, expenditures and environmental interventions due to highway construction are allocated based on total ton-kilometer performance. Expenditure on highway infrastructure operation and land use has been allocated based on annual vehicle kilometers traveled.
Activity Description
This dataset represents a Class III heavy-duty truck (payload >26t), emission level National IV, providing 1 ton-kilometer transport service. The dataset covers the entire transportation life cycle, including vehicle production and maintenance, freight transportation, as well as road pavement construction, operation, maintenance, and disposal.
Process Description
This dataset can be used for 1 t·km freight transport service using a heavy-duty type III truck (payload > 26 t) meeting China IV emission standards. It represents a transportation service providing one ton of freight over a distance of 1 kilometer, considering only cargo transport. The vehicle operates on diesel fuel.
