A comparative analysis of several vehicle emission models for road freight transportation

Reducing greenhouse gas emissions in freight transportation requires using appropriate emission models in the planning process. This paper reviews and numerically compares several available freight transportation vehicle emission models and also considers their outputs in relations to field studies.

Research highlights
► We review and compare six vehicle emission models.
► We simulate different scenarios to test factors affecting fuel consumption.
► Predictions of the models vary as compared to actual fuel emissions.
