In this paper, I perform an analysis of the time to traverse different paths from a source to a destination in an urban city based on data gathered by a vehicle-to-infrastructure (V2I) intelligent transportation system (ITS) architecture. Vehicle tracking devices have been installed in 15 vehicles that frequent the University of Alaska, Anchorage on a daily basis. This data has been analyzed using FreeSim (http://www.freewaysimulator. com) to determine the fastest path from the university to a

During the period of this research, two vehicles departed from the university to the destination along the fastest path and shortest path, respectively, each day of the week at 5:00p.m. to determine the actual amount of time to traverse each path. The fastest path traversed proved to be faster than the shortest path 67% of the time, and the calculated fastest path proved to be faster than the shortest path 84% of the time. I provide an analysis of these paths and give reasons as to why the fastest path was not always faster than the shortest path.
