Terms And Definitions
Gross Weight: The weight of a fully loaded vehicle in tons
Vehicle Characteristics: What type of vehicle has been used (tipper, articulate, rigid)? Under what driving conditions?
LBEP: Load-based emission percentage
The share of carbon emissions (fuel consumption) due to the weight of the load on the vehicle, assuming that the vehicle is fully weight-laden
Fuel Consumption/Carbon Emissions: Since they are arguably proportional to each other, they have been reported jointly
Observation Type: How has the observation been obtained?
Direct: Measure the fuel consumption of the vehicle during different runs with different runs, under given driving conditions
Driving Cycle: Use an engine emissions model to compute emissions, but use a driving cycle as the speed profile
Fixed Speed Model: Use an engine emissions model but assume that speeds are fixed
Properties Of Results: The speeds used in the CMEM fixed speed models are chosen to model low (20 km/h), medium (50 km/h), and high (80 km/h) speeds
