In the study we summarize in this paper, we aim to develop a solution that helps to reduce the gasses exhausted from motorized vehicles in the area of a university campus focusing on the emissions from shuttle services serving the internal area of the campus. We are motivated by the idea of evolving the possible extensions of campus based research to city based, considering that campuses are small scale settlements, with their dormitories, social centers, faculties, and etc. In order to evaluate daily emissions from shuttle vehicles serving the campus-wide area in a ring-based fashion, we employ different emission calculation methods in terms of the scale, i.e., macroscopic and microscopic, by using GPS trajectory data that is obtained on site by measurements. We discuss the temporal and spatial effects of acceleration of shuttle services on emissions for approximately 12 hours of operation.
