Portable emission measurement systems (PEMS) are increasingly being used in a variety of transportation research projects to determine the impact of real-world vehicle emissions. One of the key questions that remain is how well these systems perform

Emissions from "low emitting" modern vehicles were measured on-road using a Fourier transform infrared (FTIR) on-board emissions measurement system. Twenty vehicles were tested on road and on a chassis dynamometer. A subset of four vehicles was teste
