Imperial College London conducted research into the emissions factors used to model transport derived NOx emission
Emissions Analytics’ real-world emissions inventory contains data from more than 800 passenger car tests in the UK and over 400 from the USA. This data has multiple applications from air quality investigations to automotive research and development. One utilisation of the data was a study of the relationship between vehicle kinematics and NOx emissions and how this compares to the data used in traffic modelling software.
Imperial College London conducted the research and found a variation between models using unrealistic emissions factors and measurements of real-world operation which may cause significant issues for policy makers.
