| Many previous efforts have been made to use global positioning system (GPS) data gathered from mobile units to measure freight network performance. While the majority of these previous works were instrumental in establishing the technical reliability of GPS information and using that information to measure basic network performance, there have been fewer attempts to measure performance specific to freight networks, specifically to classify stops (i.e. stops for deliveries, unscheduled stops and traffic stops). In this master's thesis I will demonstrate my efforts to define new, freight-specific, performance measures and some of the advanced algorithms used to quantify the relevant data. |
