Remote sensing devices utilize infrared light absorption properties within a vehicle's exhaust plume to determine pollutant concentrations exiting from the tailpipe.
Vehicle emissions vary greatly depending on a number of factors, including engine load.
Engine load, in turn, depends on several vehicle operational parameters, such as vehicle speed and acceleration. In this study, we examine the variation of vehicle emissions measured by a remote sensing device with respect to different speeds and accelerations. The parameters of speed and acceleration are carefully measured for a set of different vehicles travelling by the remote sensor and the development of a functional relationship between speed and acceleration and remotely sensed emission levels is explored.
