• Remote sensing emission measurement is a method to measure real driving emissions to identify high emitter vehicles. High NOx emitter vehicles are recognized among the selected 14 vehicles of the University of Alberta fleet. By combining remote sensing and on-board diagnostics (OBD) data, an understanding of vehicle operation and its emission signature was developed. Out of 28 measured samples, seven samples from seven different vehicles had high NOx emissions. The results show that vehicles working in part-load operational conditions are more likely to produce more NOx. In contrast, no high NOx emitter was identified among the vehicles driven with medium or high load.
