Remote sensing of motor vehicle exhaust emissions
This report provides a comprehensive overview of vehicle remote sensing, an emissions measurement technique which has been used for more than 25 years to evaluate emissions from passing motor vehicles in real-world driving. Review technical details of the vehicle remote sensing test method, describe the multiple types of emissions analyses that can be conducted with remote sensing data, and explore areas where remote sensing can supplement emission test methods currently used in the European Union light-duty vehicle regulatory program.
