A review of on-road vehicle emission inventory

The large increase in the on-road vehicle population China has raised sustainability concerns regarding air pollution prevention, energy conservation, and climate change mitigation. Vehicle emission inventory is an irreplaceable tool to characterize temporal spatial distribution of pollutant provide guidance policy makers with effective controls. This review paper reviewed two kinds typical inventories. top-down inventories calculated based on static datasets (e.g., population, kilometer traveled, fuel consumption). These could track historical emissions abatement progress examine potential benefits from future regulations. technological evolution intelligent transportation systems have facilitated satisfy increasing sophisticated management demand. bottom-up link-level are development availability real-world traffic profiles. To simulate patterns high-resolution, demand model machine learning methods employed elucidate emissions.
